The human body uses two main energy sources, glucose and fat. The glucose is in the bloodstream and stored in the form of glycogen in the muscles and in the liver, and the fat in the adipose tissue and the fatty acids.
Metabolic flexibility is the body's ability to optimize the consumption of each energy substrate in function of the intensity of the physical exercise.
The egg has been one of the main victims of the absurd war that has been waged during the last few decades against the cholesterol. It all started in the 40's when Ancel Keys he began his particular struggle against the saturated fats. Such was their fanaticism and hatred of fat that ended up earning him the nickname of Mr. Cholesterol.
Sadly, despite not exist not a single clinical study to support their crazy theories, the influence of his ideas has come to our days. In fact, to speak of "cholesterol" we owe it to Ancel Keys.
The theory of energy balance established from the first law of thermodynamics, that the energy that enters our body, the less that comes out is equal to what is stored in the form of fat.
This statement is true but does not explain the process of accumulation of the fat. The first law of thermodynamics is a universal truth, which is always met, but that has nothing to do with the metabolic processes of fat accumulation.
The phytosterols are the food industry equivalent of the statins for the pharmaceutical industry. A very lucrative business, in this case the of the functional foods to reduce the cholesterol. Do I sound?
Phytosterols are molecules of vegetable origin that have a structure very similar to cholesterol animal competing in the intestines with the absorption of cholesterol. The food with the highest amount of phytosterols are: oils, nuts, seeds, legumes and whole grains.
The microbiota it is the large community of microorganisms, which covers the body of the human being. It is a complex ecosystem of microbes, comprising bacteria, fungi, and other microorganism. For every human cell there are 10 bacteria and its more of 3 million genes exceed 150 times the human genome.
The intestinal microbiota it is the part of the microbiota that we host in our intestines. Approximately represents 70% of the total. Let's not forget that the surface of the intestines is equivalent to the area of a tennis court (approximately 300 m2).
