As soon as it comes to wonder about his diet, he becomes sometimes difficult to find the right answers. Hire an approach to a change of lifestyle and diet cannot be improvised.
Although thousands of articles dealing with this topic, it is essential to speak with health professionals (dietician nutritionist), although each may have the ability to find a diet that suits him well.
Among the recurring advice found on the Internet, in magazines and popular books on Dietetics, a varied diet is often the prerequisite. However, a diversified diet may not be the healthiest according to a new study published in the journal Circulation August 11, 2018.
The scientific evidence to date does not support the notion that a varied diet is healthy or promotes a healthy weight. Some studies suggest that a varied diet can increase food consumption and the prevalence of obesity.
Eating a more diverse diet can be associated with a greater variety of healthy and unhealthy foods. Combined, such a food regime can lead to an increase in food consumption and obesity.
Eat a variety of foods is a public health recommendation around the world for decades. Although certain directives highlight a more variety of foods, there is little consensus on what is called dietary diversity, how it is measured and if it is a food goal healthy.
Choose foods that are healthy, adapted to its budget or taste, rather than diversity
The authors of this recent study conducted a thorough scientific review article published between January 2000 and December 2017.
The main conclusions are in 3 points:
- There is no evidence that greater food diversity promotes a healthy weight or optimal nutrition.
- There is evidence that a greater variety of food options in a meal may delay the feeling of satiety of the people, thus increasing the amount of food they consume.
- Limited evidence suggests that greater food diversity is associated with consumption increased calories, unhealthy eating habits and a weight gain in adults.
Of these comments, the authors conclude that instead of telling people to eat a variety of foods, food recommendations should focus on adequate consumption :
- of plant foods such as fruits, vegetables, whole grains,
- lower dairy fat, vegetable oils (not tropical), poultry and fish,
- limit consumption of red meat, sweets, and sugary drinks.
Finally, “choose a variety of healthy foods, adapted to its budget or taste, and respect, can help people maintain a healthy rather weight to choose a wider range of foods, even moderation,” says the study.
