The recommendation to eat more than three times a day is one of the most widespread food councils in industrialized countries.
Studies in animals have carried out 2 meals daily show that this number of intakes is beneficial to health and lengthens life expectancy.
Soon these test results are expected in humans. The effect of the number of daily intake on metabolism is studied for over 40 years.
Until recently research has confirmed that eating five or six times a day has a positive impact in preventing and treating diseases such as obesity, cardiovascular disease or diabetes. Also have linked the increased frequency of consumption of foods with a decrease in the amount of body fat, concentration in the blood total cholesterol and LDL cholesterol and glucose intolerance.
Other studies also found the relationship between the frequency of consumption, not breakfast and quantity of meals taken away with the risk of obesity.
New evidence from the animal kingdom
The calorie restriction, reduction in the number of meals and fasts for one day to another can suppress the development of various diseases and increase life expectancy in rodents. These eating habits, laboratory rats experienced greater protection against degeneration in animal models of Alzheimer’s, Parkinson’s and cardiovascular diseases such as myocardial infarction.
It has also proven an increase in resistance to stress. Thus, a study by the Neuroscience Laboratory and the Center for Gerontological Research Baltimore (USA) finds that the decline in the contribution of calories and intermittent fasting rats increase in the production of a substance in the brain, or BDNF ‘ brain-derived neurotrophic factor ‘.
According to the study, this component increases the resistance of neurons to natural degeneration by the passage of time and stimulates their recovery in case of injury or illness.
After striking these data, recently published research on the effects of reducing the frequency of meals in healthy adults, without reducing the supply of calories and maintaining the recommended intake of vitamins and minerals.
The results indicate that there is no change significativosm. However, when consumed one meal per day, there is a significant decrease in body fat mass. By contrast, showed a higher bad temper and an increase in blood pressure and the concentration of total cholesterol in the blood.
The Department of Biochemistry at the School of Medicine, Maltepe University in Istanbul (Turkey) also casts recent data. The Ramadan is the month of fasting of Islam, during which Muslims do not eat healthy or drink any liquid during 12 hours a day.
This custom became religious, therefore, a model of intermittent fasting that has been studied by scientists from the university.
It has been discovered that this type of intake does not reveal significant changes in levels of total cholesterol, LDL or triglycerides. However, increases the proportion of good cholesterol (HDL), which reduces cardiovascular risk and increases the body’s ability to combat inflammatory processes.
The recommendation professional
Scientists have raised the need for more research and make further controlled studies on how human health affects the frequency of daily intakes. The same researchers predict that it will take time and many jobs accredited to reach conclusions that can then extrapolated to the general population.
Therefore, the current recommendation for healthy people remains the eating four to five times a day.
So far there is a large body of literature that proves this practice as food for good health. In addition, the three daily meals are fully assumed in the food habits and culture of Spain.
The dilemma of energy
The quantity and frequency of meals are also essential aspects with profound effects on longevity and health of laboratory animals.
In people, an excess of energy is associated with an increased incidence of cardiovascular disease, diabetes and certain cancers. Also, it was found that overeating is a fact involved in major diseases responsible for death in developed countries.
