Insulin, Glucagon and Eicosanoids
Food is really the most efficient hormone delivery system. Simply put, different types of food affect different types of hormones, which are chemical messengers. This is why most of my programs and diet plans evolve around a 40-30-30 breakdown, which translates into 40 percent of calories from wholesome and essential fats, 30 percent from slow acting carbohydrates and 30 percent from lean protein foods.Carbohydrates (think sweet potatoes, yams, peas and squash) stimulate the secretion of the hormone insulin, which is known to lower blood sugar levels and acts as a fat-storage hormone. Proteins (poultry, beef, chicken, fish, tempeh and beans) produce the hormone glucagon, which raises blood sugar levels and mobilizes fats from storage.
My Take on Insulin
Insulin, as many of you are now aware, is basically the key hormone that is the blood sugar controller after you eat any type of carbohydrate. Insulin helps muscle tissue use blood sugar as fuel for energy, and it helps store excess blood sugar in two ways.First, insulin helps store blood sugar in the liver and stores energy as glycogen in the liver. However, the body can store only a limited amount of glycogen. Any excess beyond what the body can store is converted to body fat, again with the assistance of insulin. To increase glucagon relative to insulin, and thus enable the body to access body fat better, your body requires a more balanced proportion of carbohydrates, protein, and fat at each meal. Along with a more balanced diet, exercise also reduces insulin levels.
Glucagon
The protein hormone glucagon works in opposition to insulin. What insulin puts away in storage, glucagon puts back into use. The two hormones do not conflict with one another in the bloodstream, because when the insulin level is high, the glucagon level is low and vice versa.When your blood sugar level drops, the pancreas secretes glucagon. It is believed that both protein-rich foods and exercise induce this process. Glucagon causes the stored sugar glycogen to be released back into the bloodstream to restore the blood sugar level. In addition to releasing glycogen, glucagon releases fat from adipose tissue. This fat is then burned as fuel.
Eicosanoids
As we all now know, we need the right kinds of fats in the diet to provide the essential fatty acids that become part of the eicosanoids. Eicosanoids are natural hormones secreted by the body that control our bodily functions on a minute-by-minute momentary basis.Prostaglandins are the only eicosanoids most people have heard of, and that is due to the importance of prostaglandins in the male sexual system. But eicosanoids have a much larger role to play in human biology than they are generally credited with. In fact, some authorities claim that eicosanoids control just about all hormones and every bodily function. They are known to be affected by the nutrients we absorb from food.
All-in-all, think of food as the most efficient delivery system for hormonal balance. We no longer eat for calories, but we eat for our hormones. To your health!
