THE carbohydrates are organic molecules, made up of carbon, oxygen and hydrogen. They constitute the main source of energy for our body – and particularly for our brain.
We find the simple carbohydrates (glucose, fructose, lactose and sucrose), quickly assimilated by the body. We talk about “quick sugars”. They are found in sandwich bread, industrial cakes, candies and chocolates, but also in fruits, vegetables and dairy products. At the same time, we also have the complex carbohydrates. These are absorbed more slowly by the body. They are found in foods containing starch, cereals and dried vegetables.
Carbohydrates should represent between 50 and 55% of the total energy intake provided by the daily diet. A deficiency can cause deleterious effects on the body.
Yet for some people, carbs get a bad rap. However, while some should be limited to reduce the risk of diabetes and weight gain, others should be favored. This is what has just been demonstrated by a new study conducted by American researchers and published within the British Medical Journal.
Choose non-starchy vegetables like broccoli, carrots and spinach
The researchers conducted their study on 136,432 men and women aged 65 or younger over a 24-year follow-up period. Patients were in good health at the time of enrollment and were asked to complete several questionnaires detailing their medical history and lifestyle.
The researchers observed an average weight gain of 1.5 kilos every four years, or nearly 9 kilos over the period studied.
In question according to scientists? Certain vegetables high in starch. Increased consumption of carbohydrates from refined grains, starchy vegetables (potatoes, corn, peas) and sugary drinks lead to greater weight gain around age 50.
On the contrary, it would be necessary favor fiber and carbohydrates from whole grains and non-starchy fruits and vegetables (without starch). Researchers cite broccoli, carrots and spinach.
“ Most of these associations were stronger in people with excess body weight, highlighting the potential importance of carbohydrate quality and source for long-term weight management. », Specify the researchers in a press release. They point out that these associations were greater in women than in men.
