Firemen Causing Fires!

This past week I stumbled across a discussion online of a TV show that aired recently. The show told an interesting story that I’d love to share.

Many years ago, researchers and epidemiologists got together in attempt to reduce the number of fires in the United States. Fire, whether accidental or on purpose, can cause injury and even loss of life.

After sifting through all the data available, a common theme was discovered – firemen were almost always present at fires!

For this reason, the United States passed guidelines recommending that the general public avoid calling firemen in such situations. The association between firemen and fires was clear.

Sure – matches, flammable substances, and improperly wired electronics were also present in many fires. But firemen, with their brightly colored gear and fire truck sirens, were a much more apparent similarity in all incidents.

The public avoided calling firemen and even took measures to reduce the number of active firemen on duty. The number of fires grew in the U.S. every year, but since we had our culprits, we figured we just weren’t strict enough in our fight against firefighters.

For 50 years this continued, until enough people challenged the status quo. The initial studies were easily disproven. Anecdotally, people saw more reduction in fires after improving wiring in their homes and avoiding flammable materials. Enough scientists, researchers, and media sources shared alternative ideas.

Finally, in 2015, the “powers that be” have admitted, for the first time since 1957, that perhaps firemen are not the cause of fires!

Now clearly this is an analogy – but the simplicity of the message really struck home with me.

In this story, fires represent heart attacks and cardiovascular disease. Firemen represent cholesterol. Matches, flammable substances, and unsafe wiring represent man-made fats (such as canola and corn oil) and sugar.

When our nation was confronted with rising rates of cardiovascular disease, we looked at various blood markers in individuals that suffered heart attacks. The first thing we saw was high cholesterol levels. Immediately, our nation concluded that cholesterol was the cause of heart disease. For 50 years the medical community did everything possible to lower blood cholesterol levels.

However, it turns out that cholesterol in the blood, much like firemen at a fire scene, exist to protect us!

When there is inflammation within the blood, caused by overconsumption of carbs or vegetable oils, the body sends cholesterol to protect the artery walls from damage. In an ideal situation, the period of carb and unnatural fat overconsumption ends, and the cholesterol is carried away.

Atherosclerosis, or buildup of plaque within the arteries, occurs when inflammation does not end. This results in the oxidization and hardening of beneficial cholesterol.

This past week, new guidelines were set forth recommending that the public pay more attention to sugar consumption than cholesterol and fat. Keep in mind that all carbohydrates (besides fiber) are broken down into sugars eventually.

Start your day with plenty of whole eggs, don’t fear fatty grass-fed steak, and request more specifics (such as particle size and count) when your doctor tries to prescribe statins to lower blood cholesterol levels.

Just because firemen are the first to arrive at a fire doesn’t mean they are to blame!

An Avocado A Day…

It seems everyday a new study emerges showing that eating more dietary fats improves cholesterol levels. At the same time, carbohydrate consumption tends to have a much more negative affect in most diseases and health conditions.

One recent study suggests that fats found in nature, in this case avocados, are more beneficial than their man-made counterparts, such as canola and sunflower seed oil.

Although the sample size was small (only 45 individuals), the structuring was far more reliable than most diet “studies”. Most studies look at massive populations to form weak correlations between food and health. This study, however, used randomized, crossover, controlled feeding trials.

The experiment separated participants into three groups:

  1. A group eating a low-fat diet. Fat accounted for about 25% of daily calories, in line with USDA recommendations.
  2. A group eating a moderate-fat diet, accounting for 35% of calories. The extra fat calories in this group came from processed seed oils.
  3. A group eating a moderate-fat diet, with extra fat coming for one whole avocado a day. Fat still accounted for about 35% of calories.

After a mere 5 weeks, the moderate-fat group consuming seed oil saw a reduction in “bad cholesterol” of almost 10 points. The low-fat group experienced a statistically insignificant drop of less than 5 points.

The truly remarkable part: the moderate-fat group eating one avocado a day experienced an average reduction of almost 15 points!

This could be due to a couple factors.

First, avocados contain 14 grams of fiber, more than 3 servings of oatmeal! Fiber reduces blood sugar spikes and helps the body transport cholesterol.

Second, avocados are extremely nutrient-dense, providing 15% to 50% of almost every vitamin and mineral. Man-made oils contain no essential nutrients.

I started eating one avocado a day almost 3 years ago and almost immediately noticed this benefit to my cholesterol levels.

The nice thing is that avocado has a very mild taste and can be seasoned to compliment almost any dish. Sometimes I’ll have an avocado with an omelet in the morning. Other times I’ll make guacamole as a substitute for a bun when I have burgers for dinner. It is very rare that I skip this valuable and versatile food.

My final takeaway from this study:

Replace man-made fats, such as canola and soybean oil, with whole foods like avocado and coconuts. You’ll feel full longer, provide your body with more nutrients, improve blood markers of health, and get closer to eating what nature provides!

Meal Comparison, Part 3: Dinner

Today’s post will be the last side-by-side comparison of a Standard American Diet (S.A.D.) meal and a grain-free, unprocessed meal.

For Part 1, a breakfast comparison, click here. For Part 2, a lunch comparison, click here.

The healthy American dinner consists of:

Pasta1 cup whole wheat pasta (enriched)

1 cup generic tomato sauce

2 ounces low-fat ground turkey

1 cup skim milk (fortified & fortified)

1 brownie (using a recipe recommended by Ellie Kroger, Registered Dietician)

The whole foods meal contains:

Burgers

8 ounces ground beef (grass-fed)

½ avocado

1 cup asparagus

1 large sweet potato

Both meals provide 650 calories.

First, let’s look at the macronutrients and fatty acid profile:

. Total Carbs Fiber Net Carbs Protein Sat Fat Mono Fat Omega 3 Omega 6
S.A.D. Dinner 90 10 80 25 5 5 250 12500
Whole Foods 45 15 30 45 10 17 500 2000

As we saw in the previous comparisons, the S.A.D. meal provides almost 100 grams of carbs with only 10 grams of fiber and very little healthy fat. Even adding sweet potato to the grain-free dinner results in only 30 net carbs, fewer than half the carbs in the Standard American dinner.

The whole foods dinner offers a more adequate amount of healthy fat, particularly saturated and monounsaturated, aiding in absorption of vitamins, providing a stable energy source, and maintaining healthy cells.

Finally, the omega-3 to omega-6 ratio, which should ideally be close to 1-to-2, is 1-to-50 in the Standard American Diet meal. The tomato sauce and “healthy” brownie both contain canola oil, molecularly the same as corn oil, causing inflammation and cardiovascular disease.

Next is the vitamin content of both meals:

. Vit A Vit C Vit D Vit E Vit K Vit B6 Vit B12 Folate
S.A.D. Dinner 4500 20 0 3 30 0.5 1 50
Whole Foods 27000 42 0 7 83 2 5 180

No surprise here! Vegetables, meats, and healthy fats provide far more vitamins than refined grains, diary, and oils.

Finally, the mineral content of each meal:

. Calcium Iron Magnesium Potassium Zinc Copper Manganese Selenium
S.A.D. Dinner 570 5 150 1500 4 0.5 2 55
Whole Foods 130 10 150 2000 13 1 1 36

If you recall the previous comparisons, you’ll remember that grains and dairy provide more of certain nutrients.

The Standard American Diet provides more Manganese and Selenium, and ties for Magnesium. However, just a handful of nuts would close this gap and set the whole foods meal ahead in all categories.

In conclusion, the dinner based on whole foods provides more for the body, with less detriment, than the S.A.D. dinner.

I will do one more follow up post totaling the days’ worth of macro- and micro-nutrients. In the meantime, feel free to ask any questions about particular values, foods that may address shortcomings, or if you’d like me to analyze your own meal options.

Thanks for reading!

Eat Protein and Plants!

As most of you know by now, I recommend consuming 1 gram of protein per pound of bodyweight. This means that a 100-pound girl running track should eat 100 grams of protein; a 200-pound strength athlete should consume 200 grams of protein; and a 300-pound adult trying to lose weight should aim for 300 grams of protein.

The reasons for this recommendation are as follows.

  • Protein has the highest thermogenic effect. 30% of the calories from protein are used during digestion and processing.
  • Protein is the most satiating nutrient, leaving one full for 4 – 9 hours.
  • Protein breaks down to amino acids. These are not only used for cell repair and maintenance, but also trigger the release of serotonin, dopamine, melatonin, etc, in the brain. These are chemicals that affect moods, energy levels, and feelings.
  • Excess protein will either be converted to sugars, to be used for fuel, or excreted in the urine.

A reservation people have to eating more protein is that it is “dangerous for the kidneys”. Studies of individuals with renal impairment, or complete kidney failure, show a worsening of symptoms when administering a high protein diet. However, no study has ever suggested that a healthy population can’t handle high amounts of protein. Processing excess nutrients is the main role of our kidneys.

Recent studies have gone as far as feeding participants up to 400 or 500 grams of protein a day. The worst side effects reported were feelings of being “bloated” or “hot”. As a side note, these individuals gained no fat, even though they were consuming over 1000 extra calories a day from protein.

The other concerns I hear stem from certain studies suggesting that protein, specifically meat, causes cancer. Next time you hear this, look at the study to verify the following:

  • Was the meat naturally raised? Was beef from 100% grass-fed cows? Were chickens raised in open pastures, feeding on seeds and bugs? More likely, the beef was from feedlots and the chickens were fattened to the point they could not stand.
  • What were the cooking conditions? Was the meat slow roasted or seared? We already know that black, crunchy sear-marks are carcinogenic.
  • Who were the individuals in the study and how were they tracked? The average American that consumes over a pound of protein a day is usually resorting to McDonald’s and pepperoni pizza, not chicken eggs from a friends backyard or a local burger with multiple cups of fresh vegetables.

Protein does cause an insulin release and increases mTOR signaling, leading to cell survival and proliferation. This is a good thing if you are exercising and attempting to displace fat with lean body mass. However, if you already have cancer, a lower protein diet, such as a ketogenic diet, will be more suitable.

A review of all macronutrient studies shows that diets higher in fat and protein, compared to high carb diets, result in:

  • Maintenance of more lean muscle mass
  • Greater loss of fat mass
  • Maintenance, or even an increase, in strength and performance

The only downside of protein is that healthy sources may not be inexpensive.

In areas with sustainable farming (such as where I live in Vermont), you can buy directly from a farmer. You may even be able to invest in a “cow-share” or similar program, paying for the cow before the government charges various fees. I have found grass-fed ground beef for as low as $3/lb. Search around and develop a relationship with local farmers.

Grass-fed beef, or pastured chicken and pork, may cost $5 – $10 a pound in typical markets. However, sales always occur, and meat can last for up to 12 months in a freezer before it loses flavor. Investing in a meat-freezer can help save money in the long run.

Another option is to find a high-quality protein supplement. I always recommend whole food from nature, but I am aware that having a full serving of protein (4 – 8 ounces of meat/fish, or 3 – 6 eggs) is not always easy and convenient.

In these situations, find a whey protein powder that is affordable and has as few ingredients as possible. I will do a post in the future comparing different forms of protein powders and brands.

In my experience, a client consuming 1 gram of protein per pound of bodyweight, is able to experience easy improvement in body composition and performance.

Ideally, every meal should have a large serving of protein, about the size of your hand, surrounded by vegetables, cooked in healthy fats, with a serving of berries or fruit as desert. And if you’re still hungry, have seconds of the veggies and protein. Don’t wait an hour or two and resort to crackers, cookies, or other packaged goods.

Just eat more protein and plants!

Steak and Veggies

Meal Comparison, Part 1: Breakfast

Over the last year, news headlines showcased that saturated fat is not dangerous, animal products are not inherently unhealthy, and most of our health problems stem from over-consumption of refined carbohydrates.

However, change takes time. For the last 50 years, the public has been taught to fear fat and cholesterol, and to eat meals built around dense sources of carbs – particularly grains.

The science is now widely available showing that grains disrupt healthy gut function, provide an enormous carb load with few nutrients, and are inflammatory. But even with this information, many people are bewildered by recommendations to choose healthier options.

I can post in-depth articles discussing anti-nutrients, biological mechanisms, and studies…but sometimes a side-by-side comparison is more effective.

So, today I will post part 1 of a series comparing the Standard American Diet (S.A.D.) with a grain-free approach. Each post will compare two meal options, starting with breakfast!

Since I clearly favor a grain-free approach, I have taken the following steps to ensure objectivity:

I picked the healthiest standard breakfast options doctors and dietitians recommend. This includes:

oatmeal1 cup of oatmeal (not instant; fortified and enriched)

1 cup of orange juice (not from concentrate; fortified)

½ cup of skim milk (fortified with vitamins A & D)

1 handful of raisins

For the grain-free breakfast, I picked foods that conventional wisdom would classify as too “high calorie” or “unhealthy”, including:

omelet1 omelet made with 4 whole eggs, spinach, and sweet red peppers

1/2 avocado

1 tomato

2 slices of bacon

Both meals provide 600 calories and take less than 15 minutes to prepare.

After running all the foods through a nutrient spreadsheet, here are the total offerings of each meal:

Meal Carbs Fiber Protein Sat Fat Mono Fat Omega 3 Omega 6
Standard Breakfast 136 9 15 1 1.5 50 2000
Grain-Free Breakfast 25 13 35 10 20 1300 3500

The oatmeal breakfast provides a major carb bolus, with very little fiber or fat to mitigate the resulting blood sugar spike. At over 100 grams of sugar per meal, it’s no surprise that almost 30 million Americans suffer from diabetes.

These carbs also increase small, dense LDL, causing atherosclerosis. Meanwhile, the grain-free breakfast provides 13 grams of fiber, along with 10 grams of saturated fat and 20 grams of monounsaturated, both raising HDL, or “good” cholesterol.

I included a column for omega 3 and omega 6. These are both essential fats, but O-3 has an anti-inflammatory affect while O-6 causes inflammation, increasing the risk of cardiovascular disease.

Historically, humans consumed a 1-to-2 or 1-to-4 ratio of O3-to-O6. The oatmeal breakfast skews this massively, with a ratio of 1-to-40, while the omelet and guacamole is more ideal (1-to-3).

Clearly the grain-free breakfast is healthier in terms of cardiovascular function, inflammation levels, and blood sugar control. But what about vitamin content?

Meal Vit A Vit C Vit D Vit E Vit K Vit B6 Vit B12 Folate Choline
American Breakfast 2700* 125 50* 0.4* 3* 1 0.5 280 70
Grain-Free Breakfast 10000 250 70 8 184 2 3 330 560

Once again, the omelet, bacon, and guacamole trump the oatmeal and fruit in every category!

You’ll also notice an asterisk in the vitamin A, D, K, and E categories. The oatmeal breakfast offers less of these vitamins but also lacks the fat and cholesterol necessary to activate and absorb these 4 fat-soluble vitamins.

The American breakfast offers far less B vitamins, and folate, which is problematic since carbohydrates use up B vitamins in their processing. It is common for Americans that don’t consume enough animal products, yet eat a large amount of grains, to require vitamin b supplements and sometimes even injections.

Finally, let’s look at the minerals offered by each meal:

Meal Calcium Magnesium Phosphorus Potassium Zinc Copper Manganese Selenium
American Breakfast 500* 160 590 1300 2.9 0.5 2 24
Grain-Free Breakfast 170 120 600 1700 4.4 0.8 0.8 75

The oatmeal and fruit offers more in 3 categories! Grains are an excellent source of magnesium and manganese, while dairy provides a substantial amount of calcium.

I have once again put an asterisk next to calcium. Dairy and grains create a very acidic environment in the body, potentially leaching calcium from the bones.

The omelet and guacamole offer more minerals in total…but a daily serving of nuts may help shore up the few shortcomings.

As evidenced by this side-by-side comparison of a Standard American Diet breakfast, and a breakfast based around plants, animal products, and healthy fats, grains are not necessary.

There are a few minerals that are more abundant in grains which may support an argument for their occasional inclusion, but the idea that we should eat 6 to 11 servings a day is ludicrous.

Whether we look at carbohydrate load, inflammatory factors, or nutrients, grains clearly are not the “heart healthy” option we have been told.

Next time you’re contemplating what to make for breakfast, crack a few eggs and fry up some bacon – I’ve never heard someone complain that these foods aren’t more tasty…and now we know they are healthier too!

Vitamin Recommendations

Growing up, I took a Centrum multi-vitamin every day. If I was coming down with a cold, I would take supplemental vitamin C. When I first got serious about my health, switching to a vegetarian diet for a couple years, I would take Animal Pak, which had 11 pills per serving.

Currently, the only supplement I take and recommend to everyone is vitamin D.

What changed?

First, I learned that vitamin supplementation doesn’t prevent the “free radical damage” we once thought. It’s actually the phytochemicals, in fruits in vegetables, joined with vitamins that protect against DNA damage.

Second, the free radical damage that these supplemental vitamins do effectively prevent is produced by exercise. But, it turns out that our body needs free radical signaling post workout to improve. By mega-dosing with vitamins post workout, we are blunting our bodies’ ability to adapt to exercise.

Finally, studies show that high supplementation of vitamins B, C, E, and A (beta-carotene) increase mortality, sometimes by as much as 22%.

So why do I recommend vitamin D?

Vitamin D affects almost every function of the human body. Deficiencies can contribute to literally dozens of different diseases and conditions.

What about doctors or studies suggesting that vitamin D doesn’t affect health?

In all studies, subjects were given 400 – 800 IUs of vitamin D a day. A mere 30 minutes of sunlight provides 20,000 IUs. Therefore, it’s no surprise that a 25th of a natural dose wasn’t able to increase blood levels or affect health changes.

Trace amounts of Vitamin D can be found in certain foods. One egg yolk will contain about 20 IUs while 4 ounces of salmon may have up to 400 IUs.

If you want to be certain whether you need to supplement with vitamin D, get a vitamin D blood test, known as a 25 hydroxy.

Make sure your doctors tell you the actual numbers though! Most doctors won’t show any concern if your levels are between 20 and 55 ng/ml. This is usually enough to prevent rickets or bone softening, but optimal blood levels are in the 50 to 80 ng/ml range.

Depending how low your levels are, you may need to supplement with 5,000 to 20,000 IUs of vitamin D3 (cholecalciferol) a day.

Keep in mind that vitamin D is fat soluble and converted by cholesterol so it needs to be taken with a fatty meal that contains a healthy amount of dietary cholesterol.

In the summer, I take 2,000 to 5,000 IUs a day. In the winter, I take 5,000 to 10,000 IUs a day. I take it with breakfast, usually consisting of 4 to 6 whole eggs.

These specific recommendations assume that you are already eating a healthy diet (full of local and naturally raised meats, vegetables, and fruits) and avoid, or at least limit, grains and processed foods.

The digestion of carbohydrates, particularly grains, uses a massive amount of B vitamins, found most abundantly in meat. If you diet is too high in the former and too low in the latter, you may need a moderate dose of vitamin B supplements. I still would recommend against mega-dosing though.

There are certain other situations that may require additional supplementation but I’ll discuss those in a different post.

As you can tell, our understanding of supplements has changed greatly over the last decade. It used to seem so simple to merely pop a pill and have 100% of your vitamins and minerals for the day…but we now know that there is no substitute for a natural and varied diet.

Hope all this helps – both in terms of health and saving a few dollars on vitamins!

3 News Articles

I know I reviewed a news article just last week, but this week I wanted to try something new and discuss multiple articles at once.

My hope is to provide more information at a time. Reviewing multiple articles also means I won’t get into the same level of detail – but this may make my postings easier to get through (I know not everyone is as interested in the scientific details and mechanisms).

The first article is about the updated F.D.A. guidelines recommending women that are pregnant or breast-feeding consume at least 8 ounces, or half a pound, of fish a week. This is a major shift in our nation’s guidelines.

Some fish, such as albacore tuna, have high levels of mercury that can be dangerous to women and infants. However, sardines and salmon (that happen to have the highest omega-3 content), will have much lower mercury because they simply do not live as long. As previously mentioned, mercury binds with selenium (found in high amounts in fish) so our bodies will not absorb the mercury.

An interesting thing I learned back in college: in the U.S., we recommend women avoid alcohol and eat vegetables while they are pregnant. However, in France, pregnant women used to be told to consume wine and to avoid certain vegetables such as spinach and broccoli.

As with everything, our knowledge is constantly changing and food producers are powerful enough to influence health recommendations.

Just consume the foods humans were meant to eat, in the quantity that is realistic in nature, and be aware of food sources. This way you will know if it contains more of something (mercury) or less of another (magnesium) than it once did.

The next article goes along with the typical understanding we are slowly coming around to – that saturated fat has no correlation with heart disease.

By now, we know that the science to vilify saturated fat and cholesterol was falsified:

“But as Tiecholz and other critics point out, Keys cherry-picked the seven countries he visited: the United States, the Netherlands, Finland, Yugoslavia, Italy, Greece and Japan.
Noticeably absent? Countries well known for their rich fatty foods but without high rates of heart disease, like Switzerland, Sweden and West Germany.
Based on his study, Keys promoted the Mediterranean diet: a diet high in fruits and vegetables, along with bread, pasta, olive oil, fish and dairy. But Teicholz pointed out that Keys visited Greece during Lent, a time when people abstain from eating meat, which in turn skewed his data.”

But, I also wanted to share this article for another quote:

“Take the 30-year follow-up to the landmark Framingham Heart Study, for example. It is one of the largest epidemiological studies evaluating the roots of heart disease in our country.
In the follow-up, scientists found that half the people who had heart attacks had below-average cholesterol levels. In fact, scientists concluded that “for each 1% mg/dL drop of cholesterol, there was an 11% increase in coronary and total mortality.””

This shows that lower total cholesterol levels increases ones risk of death!

I still think triglycerides, carried by oxidized (small and dense) LDL particles, can be a good predictor of inflammation and cardiovascular risk. However, high total cholesterol, with high HDL and fluffy and benign LDL, is actually protective for the body.

And, finally, the last article I’ll share with you today is comparing the sugar content of fruit juice and sugar.

Sound familiar? Scroll back a few months on my blog and you’ll see a post I had detailing how drinking orange juice is the same as drinking a coke, taking a fiber pill, and a multivitamin. Well, now the mainstream is coming around!

I always stay open to new information, and love to learn when I’m wrong, because it means I’m learning something new…but I do have to pat myself (and my “nutrition guru” peers) on the back occasionally.

Not that staying more up-to-date on research and delving into biological and chemical mechanisms more often than CNN, New York Times, and NPR is any amazing feet – things only make the news when there’s a catchy headline, photo, or agenda!

Well, I hope these 3 articles were interesting and helped provide just a few more reasons to move away from a diet based on processed foods and towards a lifestyle based around nature.

See you next week!

The Most Nutritious Foods

As many of you know by now, I try to consume the most nutritious foods possible. However, I’ve never listed exactly what foods provide the most nutrients per serving.

Advertisements claim that certain foods are important nutritionally. Markets assign numbered scores to various products. Most of these rating systems, such as NuVal and ANDI, are inaccurate for a number of reasons.

First, they look at nutrients that are not essential for life, and conversely, overlook nutrients that are necessary for life. Second, they draw from disproved nutritional norms, such as dietary cholesterol and saturated fat being “bad”. Thirdly, they are designed by agricultural companies or individuals with a bias.

Scientists, such as Loren Cordain and Mat Lalonde, have done extensive work in the last few decades to redesign nutrient rating systems. They set aside non-essential nutrients in food and focused purely on what the body must consume from outside sources.

The body cannot produce the following:

Fatty Acids: Omega 3 and Omega 6

Amino Acids: isoleucine; leucine; lysine; methionine; phenylalanine; threonine; tryptophan; valine; histidine

Vitamins: A; Bp (choline); B1 (thiamine); B2 (riboflavin); B3 (niacin); B5 (pantothenic acid); B6; B7 (biotin); B9 (folic acid); B12; C; D; E; K

Minerals: calcium; chloride; chromium; cobalt; copper; iodide; iron; magnesium; manganese; molybdenum; nickel; phosphorus; potassium; selenium; sodium; sulfur; zinc

These nutrients were plugged into the following formula to determine nutrient density:

(sum of essential nutrients per serving) ÷ (weight per serving)

I’d like to make a few points before posting Mat’s nutrient density list.

First, the database he drew from did not have complete data for certain nutrients.

The database did not differentiate between preformed vitamins and their final form. Vitamin A, “beta-carotene”, in sweet potatoes and carrots, must be converted to “retinol”, found in egg yolks and liver. Vitamin K1, found in green leafy vegetables, requires conversion to K2, found in grass-fed dairy.

There was no way to account for bioavailability of nutrients. Most grains, legumes, nuts, and seeds contain high levels of phytates which prevent absorption of nutrients and minerals.

Finally, and most importantly, the diet, age, and lifestyle of animals were not specified. Grass-fed beef, raised on open pastures, is much healthier than corn-fed beef, raised in stalls that restrict movement. Also, mature ducks having more nutritional value than baby ducks.

Taking this unavailable data into consideration, we can assume that most animal products would move up a few spots. This is because most plants have limited amino acids and fatty acids, and the vitamins found in vegetables must be converted or activated.

Without further ado, the ranking of nutrient density averages for the food groups:

1.) Organ Meats and Oils
2.) Herbs and Spices
3.) Nuts and Seeds
4.) Cacao
5.) Fish and Seafood
6.) Pork
7.) Beef
8.) Eggs & Dairy
9.) Vegetables (raw & unprepared)
10.) Lamb, Veal, and Wild Game
11.) Poultry
12.) Legumes
13.) Processed Meat
14.) Vegetables (cooked, canned, blanched, pickled)
15.) Plant Fats and Oils
16.) Fruit
17.) Animal Skin and Feet
18.) Grains and Pseudocereals (cooked)
19.) Refined and Processed Fats and Oils
20.) Grains (canned)
21.) Processed Fruit

Many people will be surprised by how low grains appear on the list. The nutrient value of raw grains would place them in the top 5. However, our bodies cannot digest raw grains. Taking nutrient loss during cooking and expansion of grains (1/4 cup raw rice = 1 cup cooked rice) into account, their value decreases dramatically.

I was quite surprised to see herbs, spices, and cacao near the top of the list. I always considered these foods to be enjoyable additions to a healthy diet, but not the most valuable sources of nutrients.

Two final notes regarding this list:

It is not a requirement to eat the most nutritious foods all the time. Certain nutrients, such as activated vitamin A (retinol) and selenium (abundant in Brazil nuts) are actually toxic in high doses.

Second, as previously mentioned, this rating system only looks at essential nutrients. Many vegetables contain antioxidants and fiber that can improve health, even though they are non-essential for life.

I would recommend consuming foods higher on this list and keeping your meals full of vegetables.
For Mat Lalonde’s complete presentation, follow this link to YouTube.

Matheiu Lalonde has a PhD in Organic Chemistry and a postdoctoral degree in Inorganic Chemistry from Harvard. He teaches, lectures, and is the Science Safety Officer at Harvard’s Department of Chemistry and Chemical Biology. I have to give him credit for the motivation behind, and information in, this post.

I hope this sets aside all confusion of what is best to eat.

Keep in mind that human-run studies can be flawed, correlations from epidemiological studies can be weak, and research can be conducted to prove a point, rather than discover the truth, but the actual make-up of foods cannot be disputed!

Improve Your Hormone Levels

As I promised a few weeks ago, I’ll provide some simple steps you can take to improve your hormone levels.

Just to reiterate, your hormone levels dictate a large part of your health, performance, and body composition.

For the actual details about healthy hormone levels and effects, please refer to my post about testosterone.

Without further ado, here are the safest and most effective tactics to manage healthy hormone levels:

• Make sure you are consuming a nutrient rich diet.
Any nutrient deficiency has the potential to negatively impact hormones, but the biggest culprits will be zinc, vitamin A, vitamin D, and magnesium. I’ll do a post explaining which foods have the most nutrient value later on but, for now, I’ll just recommend oysters, liver (if you can stand the flavor and have a high-quality source), avocados, eggs (particularly the yolk), and plenty of naturally-raised, well-treated meats, full of the fats and proteins your body needs to manufacture testosterone.

• Consume dietary cholesterol on a regular basis.
The best sources are eggs, shrimp, and fattier cuts of beef (grass-fed of course!). Cholesterol is a precursor to testosterone production. Keep in mind, the cholesterol you eat will only raise your HDL a little and have hardly any effect on triglycerides (the “bad” cholesterol in the blood).

• Avoid over-consuming carbohydrates.
Starches and sugars will cause insulin spikes in the blood. Your muscles can only store so many carbs before the insulin forces carbs to be stored in fat cells. This insulin will also disrupt normal hormone signaling.

• Get 8-9 hours of sleep a night.
During the first few hours of sleep, your body will release the largest amount of human growth hormone, allowing your body to recover from the day. I know everyone says they can get by with 6 hours…but your body composition, mental performance, and energy levels will always be better with a proper 8 hours of sleep.

• Lift something heavy a few times a week.
This will stimulate the body to produce testosterone to recover from the stimulus. Again, keep in mind that heavy lifting isn’t what produces bulky muscles…that would be higher repetitions (8-15) for multiple sets (3-4) with very little rest (30-90 seconds).

• Do some high intensity interval training.
Refer to my post from a few weeks ago. This has the potential of benefiting hormones more than any other exercise.

• Avoid alcohol.
Or at least try to moderate your intake. Alcohol will convert testosterone to estrogen within the body.

• Avoid stress.
This might be the most difficult but cortisol, released when you’re stressed, will lower testosterone levels. Some of the easiest things you can do are to limit your caffeine intake and take time during the day to stare off into nature or distract yourself from the stresses of our modern lives.

One final method for increasing testosterone levels is to supplement directly with hormones (a.k.a. steroids). However, this is a much more controversial and potentially unsafe method that I’ll save for another post.

Give all these things a try and see if you notice an improvement in body composition, strength, recovery, or just general mood and energy on a daily basis!

How To Improve Your Cholesterol Levels

As promised, this week I’ll give you a few easy tips to improve your cholesterol levels. Before I start though, I want to remind everyone that “improving” cholesterol levels does not necessarily mean lowering them.

If you remember my post about cholesterol, you’ll remember that the body creates and uses LDL as a temporary bandage that, once the threat to the body is resolved, HDL will transport back to the liver to be excreted. It is only when inflammation persists in the body that LDL becomes oxidized, hardening and risking blockages in the arteries.

In fact, low total cholesterol levels in the body have been linked to shorter lifespan! Therefore, for this post, we’ll talk about how to adjust your cholesterol levels to the optimal zone…as opposed to the range statin companies usually promote.

First off, the easiest number to alter is your HDL. This is what carries cholesterol back to the liver after it has served its purpose.

The best way to boost your HDL is to consume more monounsaturated fats, such as olive oil and avocado. Consuming these in a raw form, as opposed to cooking them, will be more beneficial. Also, conjugated linoleic acid (CLA) found almost exclusively in grass-fed beef and dairy, will help raise HDL.

In addition, weight training and moderate aerobic activity are shown to increase HDL.

Now, on to LDL. To reiterate, high LDL is not necessarily a bad or dangerous thing. However, LDL can become oxidized in the blood so I understand why people may want to lower their LDL numbers.

To lower LDL, be careful when consuming other saturated fats. Saturated fat is actually the safest to consume, and most stable source of energy for the body, but make sure you’re consuming it from natural sources. This would include coconut products (again, with minimal processing), grass-fed beef, and other humanely raised animals fed a natural diet, with plenty of space to roam and forage.

Exercise may also help control LDL levels since low-level aerobics will improve the body’s ability to metabolize fats for energy.

Finally, the only truly problematic form of cholesterol found in the body is triglycerides. Anytime you see claims that cholesterol in the blood is dangerous, I will guarantee the samples were people with extremely elevated levels of triglycerides and low HDL.

The best way to decrease your triglyceride count would be to avoid processed or heated polyunsaturated fats which are highly unstable and prone to oxidization.

I’m not saying to fear nuts and seeds and every food containing high amounts of omega-6 (the primary inflammatory constituent of poly-fats). Just avoid foods that are high in this AND have been processed or altered. Examples of foods to avoid would be corn oil, soybean oil, and other vegetable oils.

Finally, limit your sugar and refined carb intake. Again, no need to fear fruits, sweet potatoes or other whole foods; instead, skip the center aisles of the market made up of processed and packaged food.

Please keep in mind that all my suggestions of what to eat more or less of are based on the assumption that we already know things like candy, chips, ice cream, and soda are unhealthy. Fortunately, our health and nutrition systems have not yet become so infiltrated by major corporations that McDonalds and pizza is labeled as healthy.

Nonetheless, as exemplified by my own past food choices, there is still a great deal of confusion regarding what is optimal for our bodies. Just last month Mazola ran a massive marketing campaign (and must have spent billions of dollars) to convince researchers and doctors to claim that corn oil is “safer for the heart” than extra virgin olive oil!

And with that, we should all have a decent level of knowledge regarding what to consume and not consume to maintain the most beneficial cholesterol levels in our bodies.

Hope it helps!
