Nutrition Myths that science has disproved
Nutrition is a stricken baseless beliefs and myths field. Or not, because some of them actually have their origin in authentic scientific research.
Nutrition is a complicated and full of rumors field. As an everyday activity, we all “know a lot” about food and its details. But we have spoken countless times about how difficult it is to treat any subject related to this field. Thus, extended myths of nutrition among the population are many . Some come from misinformation.
Salt is not bad for health
This is probably one of the myths of the most widespread nutrition world . Its origin dates back to the beginning of the century when some cases of heart attacks in opulent affected their diet was associated. Until 2010, approximately doctors were sure that drinking ten or twelve grams of salt a day could cause a rise in blood pressure. This, in turn, could be responsible for cardiovascular diseases of all kinds. Over time, various groups have pressured the industry to reduce salt levels in food. .
However, most recent studies have found that there is no evidence to really support these deductions. In fact, studies show that there is no direct relationship between sodium (the alleged perpetrator of the dangers of sodium chloride, common salt) diet and the number of heart attacks or other problems. As a precaution, doctors still ask patients with heart problems that reduce the amount of salt in their intakes. But, of course, their relationship is unclear. .
Eating eggs and other myths about cholesterol
Another myth of the most widespread nutrition. And dangerous. Cholesterol is not only not bad, but it is necessary. Cholesterol is associated with meat, eggs and other foods. Again, the origin of this myth is in the medical field. At the time it was discovered it was crucial to associate to an increasing awareness of cardiovascular problems. However, again, the relationship was misunderstood. From what we know today, the relationship of cholesterol in food with heart problems is very weak. According to recent studies , not even the paper of the kind of cholesterol (HDL, LDL …) It is as clear as expected. In any case, because cholesterol diet affects the metabolic cholesterol very slightly. Except if we do not get the necessary or their precursors, at which time it can be dangerous. .
The desayuno is the most important meal of the day?
not all nutrition myths are false. Some simply are not true. Or at least, we have no evidence that they are. This and precisely one of those examples. To date, as increasingly felt nutritionists, the asunciones made with regard to breakfast have an unfounded origin. That is, it is easy to attribute profits that seem logical. But we do not have strong scientific evidence that the substantiating . Moreover, some studies suggest that changing eating habits and force us to eat a breakfast that is considered “healthy” or within accepted parameters in myth, can translate into a gain unhealthy weight.
not always gain weight after a “flash diet”
There are certain recommendations nutritional quite strict when it comes to dieting. For example, it is advisable to lose weight gradually. Moreover, these same lines of recommendations warn against making a “flash diet”, ie, lose weight very quickly. However, this could be another of the myths of nutrition. And is that recent estudios suggest that there is no real relationship between the rate at which weight and recovery is lost. That is, the back fat should be more to other factors than the way we’ve had to lose weight. It is a little evidence that contradicts what he tells us why. But this we always have … reason. Despite the redundancy. That’s what the scientific method. .
Bad fats are not as bad
As with cholesterol, one of the most widespread myths of nutrition refers to saturated fats. Although in this case it remains a scientific evidence on its overconsumption and certain risks to health, this is not as strong as previously thought. On the contrary, according to the estudios, it is more dangerous to remove from the diet consumed in excess . And it is that saturated fats, like cholesterol, saturated fats, which are considered “bad”, are also indispensable for our life. Still, consumption remains moderate advised; but within a much looser than before lines.
Nutrition is not a simple matter
As we said above, and repeat again and again, nutrition is a field very complicated. Feed is one of the basic functions of any living being. We depend on it. And this means that its implications at physiological and metabolic levels are … too complicated to understand in full . We try to envision a huge picture based analyze your strokes. .
It is therefore very common myths run into nutrition as we gather up. Nutritional guidelines change over the years, as we know more about our own body and its mechanisms. But before such a scenario there is one thing we can always do: feed sparingly, maintaining a healthy, varied and very important diet, do some sport
