Donate Blood!

I am always offering ways to improve health and performance. Improvement in these areas is an admirable goal for any individual.

My number one recommendation for everyone is to first improve their diet –replacing packaged foods with vegetables, fruits, and local meat and eggs.

However, an ideal diet, high in nutrient density, can have one unfavorable outcome: elevated blood iron levels.

High iron levels become an issue when an individual starts eating adequate protein but doesn’t participate in activities that result in bleeding. Historically, we would risk injury during hunting, defending ourselves from prey, or just living life with fewer comforts than we have now.

This is more problematic for men than women, as women have a natural method for disposing of excess iron through blood on a regular basis.

High iron levels in the blood can pose as an oxidative stress for the body. And, if you recall the concern of fats becoming oxidized, you’ll remember that it’s the process of oxidation that causes most of our health problems.

Many studies that claim red meat causes cancer, actually examine iron levels in the blood. It is well accepted that unnaturally high iron levels can indeed be a precipitating event in the formation of different cancers.

So, if we are shooting for one gram of protein per pound of bodyweight, and understand that grass-fed beef is the second healthiest protein source after seafood, what can we do to avoid the risks of over consuming iron?

Donate blood regularly!

This is something I have started recently and recommend for most healthy individuals, particularly men.

Not only can you help an individual that may be in dire need of blood, but you will also reduce the oxidative stress in your own body.

The American Red Cross allows you to donate blood once every eight weeks. This is because most donations will take about one pint of blood, which takes the body four to six weeks to fully replace. However, the plasma in your blood will be replaced within 24 hours so symptoms of fatigue should not last longer than this.

Donating blood is a stressor for the body, so you will need to curtail your exercise schedule accordingly. I usually donate blood on the Saturday before a recovery week. This means that I won’t have any scheduled exercise within 2 days of donating blood, and even when I do return to the gym on Monday, my workouts will be at half intensity for the following week.

Even though eating after giving blood can be beneficial, make sure you are still making healthy choices! Some donation sites still offer juices, cookies, or candy. I would recommend coming prepared with a piece of fruit or a protein smoothie.

Anemia, often caused by low iron levels, is common in our country and may be more problematic than “high-normal” levels. For this reason, I recommend getting a ferritin blood test before donating blood on a regularly basis.

On average, 10% of women nationally have anemia, while only about 2% of men have it. Because of this, I believe a regular blood donation schedule is far more beneficial for males.

Take a look at the effort you put into exercise. Consider how much time you spend shopping, cooking, and eating. Add up how much you spend on health insurance. Now ask yourself: is donating blood every few months to improve your health and possibly save a life, worth 30 minutes of slight discomfort?

Not every step we take to improve our health will directly help a fellow human – but this one will!

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!
