As a logical follow-up to last week’s post, let’s look at what we can do to reduce our risk of cardiovascular disease.
So far, we learned that eating cholesterol does not increase the risk of cardiovascular events. In fact, 75% of people that suffer a heart attack have normal or low cholesterol levels in the body. Furthermore, taking cholesterol-lowering medications (such as statins) does not reduce the risk of heart attacks in 98% of the population.
So, if cholesterol consumption is irrelevant, what is causing our nations deterioration in cardiovascular health?
One word – inflammation!
It is the process of inflammation that damages the arteries, signaling the body to send cholesterol to protect the area. And it is, once again, inflammation that damages the cholesterol in the blood, causing it to harden, leading to plaque formation and clogged arteries.
There are a few things that cause inflammation. The first is consumption of unstable, easily-oxidized fats . The worst is man-made trans-fats. These are found in most butter replacements and aerosol cooking oils. Another problematic fat would be omega-6 polyunsaturated fatty acids. The biggest offenders here are corn oil, soy oil, and other modern vegetable oils.
Many natural foods, such as nuts and avocados, are quite high in O-6’s but, as long as they are consumed fresh and in moderation, without extremely volatile processing methods, they should not be problematic.
The second biggest cause of inflammation is excess sugar in the blood. If an individual consumes more carbohydrates than their muscles can store, the excess sugar will wreak havoc in the body until insulin forces it into fat storage. Sugar is toxic in very high amounts so it is no surprise that too much, idling in the blood, causes inflammation and damages the arteries.
The third biggest cause of inflammation is eating foods that are detrimental to the gut. Eventually I will have an entire post on gut health but, to put it simply, if you eat enough foods that have the potential to damage the gut lining, the offensive compounds will pass through the gut (a condition referred to as “gut permeability”) and cause inflammation elsewhere in the body. Grains and legumes contain many of these compounds…predominantly lectins. Lectin content can be diminished through extensive soaking, sprouting, and cooking but it’s still not wise to base a diet around such a problematic food.
So, man-made vegetable oils, excessive carbohydrate consumption, and grains cause inflammation…what does that leave?
Instead of using vegetable oils, try cooking at high-temperatures with coconut oil or grass-fed butter. Save your olive oil, avocados, and nuts for raw consumption.
No need to count every gram of carbohydrates; rather, focus on more nutritional sources such as vegetables and fruits (which will also have far less calories and sugar per serving than grains or legumes).
Finally, avoid grains when you can. I personally replaced them altogether with vegetables and locally, humanely-raised meat, but I know the idea of eliminating a food group we have grown up with can be daunting. So, maybe try only eating grains when you go out to your favorite pizza joint or restaurant.
Also, don’t forget to eat your healthy fats! Monounsaturated fats and even saturated fats will be far less inflammatory than grains and legumes. Since you’ll be limiting your intake of problematic carbs, that are high in calories and low in nutrition, a few extra calories from good fats will help keep you feeling satisfied and well-fueled.
As a personal trainer, I always have to mention to stay active as well! The more relaxing walks you can take the better. Throw in a couple weight-training workouts a week and an occasional high-intensity-interval-training session (sprints, rowing, etc) and you’ll be on the path to having a perfectly conditioned heart.
Best of luck!
