Misinterpreted studies
At the beginning of information about the harmful effects of fatty foods is a study of the 1970 Ta pointed to the link between an increased incidence of cardiovascular disease and the amount of cholesterol in the blood, whose levels attributed amount of fat obtained from food. Based on this information it was recommended limit of daily intake of saturated fats in the diet at 30% maximum. A people took this recommendation to heart so. Flooded with light food shelves and have children in kindergarten now know that fats are bad. Despite a significant decrease in the consumption of fats, but the number of cardiovascular disease in the population did not significantly change. So the researchers focused on the role of fat again.
It's all sugar
Recent studies refute the original claim about the harmful fats and instead maintains that their consumption protects our blood vessels formation called. Worthy of cholesterol. Saturated fat intake in the diet is slightly increased total cholesterol levels, but does not increase the risk of cardiovascular disease. Who or what can be so significant enlargement of heart disease in developed countries? Scientists indicate sugars. Now you are by them responsible for the epidemic of atherosclerosis and diseases resulting from it. Replacing fat carbohydrates, especially those with a high glycemic index (this includes not only sweets and honey, but also the breakfast potatoes or corn chips), leads to more frequent vascular disease and heart attacks . So if you want to reduce the risk of cardiovascular disease, skip the potatoes, bread, pasta and sweet. Protect your arteries better than "light" cream.
Energy and vitamins
Fat is the most efficient source of energy that our body has. We use it all the daily acts - walking, working, running light, but also mountain hiking. Sugars come in a variety of intensive exercise, strength training and sprints. Sugars therefore to everyday life basically do not need. Even the brain, which uses the energy from glucose, is able to "switch" and the portion of energy taken from ketones, molecules derived from fatty acids. If there is no blood in large amounts of glucose, it does not mean that the brain stops working. And best of all, the combination of glucose + ketones operates more efficiently than with glucose alone.
Fats are also rich in vitamin E (antioxidant), K2 (important for the prevention of cancer) and D (important for bone health), and necessary for the dissolution of vitamins A, D, E and K in the blood.
Fats help to lose weight
If you wonder how it is possible thanks to the high-fat diet to lose weight, the answer is simple. Excessive consumption of sugars offer the body very easy source of energy that makes the body lazy and energy from fat leaves on a rainy day. Therefore fat. In addition to carbohydrates brings much more than eating fats. How many times we are able to eat a few slices of bread or a bowl of pasta and hunger persists. If the same number of calories eaten in fats and proteins, we have long enough. Thanks to the energy intake from fat and less eventually manage to burn her normal daily activities. In addition, if you start exercising, losing weight is not long to wait.
Cursed Atkins
A similar concept came years ago, Dr. Atkins and his miraculous diet when you can eat almost anything, and you still lose weight. The diet is based on high intake of protein and fat and minimal sugar intake. Although diet functioned, his recommendation was considered very controversial and doctors were concerned about the health of patients who underwent this diet. Today's conclusions rather speaks in his favor. However, we must realize that there is no ideal diet that would be perfect for everyone. It is always necessary to consider the personal health risks. Food recommendations change very often. It is best therefore to rely on their common sense, not to overeat and reasonably move.
