Scientific knowledge evolves constantly – or in successive revolutions, as others say. So the facts of today 's world may not be the same as those of the world of tomorrow. Do not forget that cigarettes were only medically recommended 80 years ago, but today and in recent years, they are "the leading cause of cancer," warnings say. What about controversial medical hypotheses of our time? We chose three nutritional hypotheses on the Reader & # 39; s Digest website:
Coffee
Experts have long accused coffee of hindering growth, raising blood pressure, angina and other causes. However, over the past decade, experts have shown that the death rate of people who consume between three and four cups of coffee per day is lower than that of the various medical causes leading to death, compared to those of others. Coffee reduces the risk of certain cancers, as well as diseases of the liver and heart. However, coffee is still accused of causing fetal growth problems if it is consumed specifically by women during pregnancy, as well as contributing to osteoporosis.
Processed meat
When the World Health Organization recommended a few years ago that the "hot dog" and other processed meats increase the risk of colon cancer, the panic of those who consume meat in their food. But studies have shown that the risk of eating such meat in moderate amounts is very low and is much lower than the risk of smoking, for example. "Other studies have shown that people who consume red meat are more likely to die from cancer, heart disease, respiratory disease, diabetes and infectious diseases than those who eat small amounts.
Vitamin Supplements
In some malnourished countries, children eat foods of poor quality, which may be deficient in food and cause serious health problems, including vitamin A, which can lead to blindness. However, in countries where food is varied and adequate, children do not need supplements.
