5 Myths about nutrition
Proper nutrition has already become a real science, not without the presence of legends and myths. Not always advice from may carry reliable information professionals, which leads to frustration and belief that diet and a healthy lifestyle in vain, because the extra weight does not go away, not to mention the risk to make heart and kidney disease, or cancers. We've put together a few common myths about foods that are prevalent for a long time, and told me that they think about the researchers.
1. Vegetables require full availability
Still tushish broccoli? If you want to get the most out of their dishes, then stop right now. The researchers found that vegetables bring to full readiness deprives them of a large number of nutrients, including soluble fiber, vitamin C and glucosinolates - component necessary for the prevention of cancer. Long cooking leads to the fact that vitamins evaporate along with the water, so the best option to cook vegetables - it quickly reheat them in a skillet with a small amount of liquid. If possible, eat vegetables raw. For example, bell pepper contained about 150% of the required daily dose of vitamin C and the temperature above 190 degrees Celsius kills all the antioxidants.
2. Oil is harmful to health
Oil is always perceived as harmful ingredients as the high content of fat - a risk for your heart, the threat of obesity and high cholesterol. But the 72 studies on the subject of oil hazard, conducted in more than 17 countries, showed that consumption of oil has nothing to do with heart disease. In addition, the oil - a source of vitamin A, D, E and selenium - an antioxidant that plays an important role in the proper metabolism.
So do not skimp on the oil in the next time you're cooking dinner.
3. The high-protein diet harmful to the kidneys
We have evolved into the most intelligent creatures that ever walked the earth, through food-based protein intake, so hard to believe that the work of evolution in the blink of an eye become harmful to the kidneys. I believe it is not necessary, since the studies that have shown harmful effect of protein, were performed on people with pre-existing predisposition to kidney disease.
If you are in good shape, the high-protein diet can help you to ask the weight without side effects, according to researchers from the Association of International Society Of Sports Nutrition. In addition, the protein can balance blood pressure, according to Dutch researchers.
4. Alcohol before bed - a pledge of strong sleep
Alcohol after a hard day, maybe it will help you quickly shut down, but that's a healthy and sound sleep to wake up refreshed with the prospect unlikely to provide. All because of what effect alcohol has on the brain. Clinical studies have shown that the brains of subjects drunk just before bedtime, show delta activity associated with deep sleep and rest. But, apart from that, alcohol triggered and alpha activity that occurs only during waking hours. Confrontation between the alpha and beta waves interrupted your sleep, so waking up the morning after the party, you feel as if he had not slept at all. During the night, your brain needs to 6-7 cycles of deep sleep, and after drinking, you can only hope for a 2-3, which means relaxation do not wait.
5. Carbohydrates after 18:00 will lead to the fullness of
obscurantism - and more! This myth is based only on the idea that during sleep the metabolism slows down, which means that the body does not have time to digest the carbohydrates eaten, leading to the formation of excess fat. But scientists have shown that even at the stage of light sleep your metabolism continues to work with efficiency of 35%, not to mention the fact that 4 hours to digest eaten, you will be more than enough. In addition, if you are engaged in fitness, even during sleep the digestion and absorption of food, as well as the burning of calories, it is faster than in the absence of physical activity.
Eating carbohydrates helps to quickly fall asleep due to the high concentration of tryptophan in the blood amino acids that make you feel relaxed and lethargy.
