Are Calories a Determining Factor in Life Expectancy?

Many times we have heard that people who follow a low-calorie diet were more likely to live longer than the rest. They have taken this belief followed for years by land researchers at the University of Washington.

According to these recent studies everything had broken down on this subject we accomplish nothing, and is that Yes it is true that in laboratory mice a caloric excess cut off the life of patients undergoing this type of power throughout his life. But in the case of humans this is not, as evidenced by the results derived from this latest research as well.

The reason for these results lies in the call growth factor insulin (hormone IGF-1), in the case of mice decreases if they consume fewer calories, but in humans it does not occur. This hormone influences the quality of life and the organic status, but was believed not only that produced it an excess of calories, but protein were also suspected of causing an increase in this hormone, this is why researchers at the University of Washington set eye on proteins instead of calories.

After conducting numerous studies with strict vegetarians and others that were not so, they detected that IGF-1 levels were lower in vegetarians, so that excessive protein intake can be the trigger for a shortening in life expectancy. In addition, they came to the conclusion that reducing proteins in our diet may help prevent certain types of cancer.

The problem lies in that many people need to eat protein to prevent malnutrition, and is that their physical and intellectual activity forces them to give your body of these important nutrients. But in this case it is important to know the origin of these, and is that they are not all the same biological value. Most proteins are those that obtain food as fish or vegetables such as soybeans, it contain high doses of this nutrient.

Since then according to this research the best way to prolong our lives for more years is basing dietary intake of fruits and vegetables that it will help us to adjust the levels of the hormone IGF-1. This conclusion shows us is that not only the fat and calories is what determines our longevity, but that proteins enter the scene. To control the intake of this nutrient researchers who have made possible this conclusion set the daily amount recommended in 0.82 grams per day for every kilogram of weight that we have.

It is important that we bear this in mind, but it is not necessary for us to obsesionemos. Of course that one varied and balanced diet It is essential to maintain good health. Variety is the spice and food repeats this principle since all the nutrients are needed in the body, but without to go or remain scarce.
