How Nutrition Affects Behavior

I wrote this essay on December 31st, 2013 based on a lecture by Russell Blaylock M.D. — Nutrition and Behavior

The human brain needs fuel in order to function, this is food. However a lot of the food that we consume daily is actually severely harmful and damaging to the brain. All components in the brain are naturally replaced every so often. It can take months, years and even decades; however some components such as the Omega 3 Fatty Acid DHA are replaced every two weeks! Brain cells are never replaced and they cannot be. So anything that harms them and kills them will permanently damage the human brain.

Our bodies need sugar in order to work properly. But, excessive amounts of it can result in low blood sugar or hypoglycemia. This produces numerous malfunctions and actions such as anxiety, depression and hyperactivity, but also more seriously: crimes, aggression and serious diseases. It can also result in your cells aging faster. The process in which this happens is this: excessive sugar causes a reactive insulin release which produces hypoglycemia. Then the adrenal gland, in order to counteract the hypoglycemia, produces three hormones: cortisol, epinephrine and norepinephrine, the last two connected with helping you to be active. These, together with the release of glutamate, by the brain, result in hyperactivity and potentially permanent brain damage.

In the 1900’s an average American consumed about four pounds of sugar a year, whereas today the average American eats about sugar219 pounds, a 2500% increase. The average adolescent eats about five times more than the recommended amount of sugar a day. More than half of the sugar consumed comes from processed foods, and the rest from soft drinks.

From much research that has been done, it has been found that among criminals the most serious offenses have been committed by humans with the most hypoglycemia. When the hypoglycemia was treated they did not commit any more crimes and their lives changed. The same was found among children who ate too much sugar, their diets changed and they had a longer attention span, they were not hyperactive and they were much healthier and smarter. They also had a better memory and clearer thinking.

Food allergies can also seriously affect the brain. Because the food that you are allergic to enters your body as a whole food, which it’s not supposed to do, it causes an immune reaction, which is triggered by the brain. We get the same result with vaccinations, with one major difference, the immune reactions go on for years. Milk, peanuts, soybeans and gluten are a few foods that can cause allergic reactions.

Deficiencies in several vitamins, such as vitamins A, B, C, D, E and K, can also affect your behavior. Lack in vitamin B1 can cause the disease beri-beri, which results in chronic fatigue and loss of memory.

In conclusion, if people did not consume so much sugar, resulting in no hypoglycemia, and there was no taking in of pollutants in the environment, along with the releasing of free radicals, people would not have to suffer from hypoglycemia and its effects, or any other diseases caused by the consuming of all of these products.

  1. Yes. I am aware sugar is not something that should be consumed in large quantities. However, a lot of health issues from sugar are from white sugar and confectioner’s (powdered) sugar. These are bleached which make them very bad to eat. Our sugar is called Sugar in the Raw. Its Cane Sugar that still contains the molasses (molasses contains huge amounts of iron, magnesium, and potassium, but white or powdered sugar has molasses taken out of it. The sugar by itself tastes like a tropical fruit and I have had a sugar cane and it tastes the same. The sugar can also be blended in a blender on the highest setting and it makes powdered sugar. Another option is Agave Nectar but I haven’t tried it.

    Here is a link to their site:

    The science behind the glucose need is (from what I can remember from 7th grade science in public school) is that the glucose (C6H12O6) and Oxygen (O2) are needed to make ATP (adenine triphosphate) which is basically energy for the human body to use. I thought it was cool.

    Nice essay!
