How does low-carbohydrate diet affect life expectancy?
A diet low in carbohydrates has been used by many people in recent years to lose weight and achieve a healthy body weight. Researchers have now discovered that a diet low in carbohydrates can shorten life expectancy by up to four years.
The researchers at Brigham and the Women & # 39; s Hospital in Boston discovered in their recent research that a low-carbohydrate diet can significantly shorten life expectancy. The doctors published the results of their study in the English-language journal "The Lancet Public Health."
Study had 15,400 subjects
Low-carb diets have recently become more popular for weight loss. A modest reduction in carbohydrate consumption or the transition from meat to vegetable proteins and fats seems healthier than a low-carbohydrate diet, according to the current American study. 15,400 participants completed questionnaires about the food and drinks they consumed, as well as the portion sizes. The scientists then estimated the amount of calories consumed by carbohydrate, fat and protein participants.
What were the sources of carbohydrates?
The researchers found that those who were 50-55 Percent of their energy from carbohydrates (moderate intake) had a slightly lower risk of death than participants from groups that consumed very few carbohydrates or carbohydrates. Subjects derived from carbohydrates from vegetables, fruit and sugars, but the main source was starchy foods such as potatoes, bread, rice, pasta and grains.
What is moderate carbohydrate consumption effect?
Researchers estimate that From the age of 50 onwards, the poband of the group with moderate carbohydrate intake would still be 33 years old. This was four years more than compared to people who consumed 30 percent or less of their carbohydrate energy. They also lived two to three years longer than the participants, who took 30 to 40 percent of their carbohydrates and 1.1 years longer than those with 65 percent or more carbohydrates.
Carbohydrates of vegetable proteins and fats replaced
The scientists then compared a low-carbohydrate diet with many animal proteins and fats to a diet with a lot of vegetable proteins and fats. They found that consuming more beef, lamb, pork, chicken and cheese instead of carbohydrates was associated with a slightly increased risk of death. Replacing carbohydrates with more vegetable proteins and fats, such as legumes and nuts, easily reduces the risk of mortality.
Low-carbohydrate foods that replace carbohydrates with proteins or fats are becoming increasingly popular. Study author Dr. Sara Seidelmann from Brigham and Women & # 39; s Hospital, Boston. The data suggest, however, that an animal-based low-carbohydrate diet is associated with a shorter total life span. That is why it must be discouraged, the expert emphasizes. The substitution of carbohydrates with more vegetable fats and proteins on the other hand promotes healthy aging in the long term.
Western high-carbohydrate diet is unhealthy
The authors predict that the high-carbohydrate diet on the west side is often less receptive to vegetables, fruits and grains and also includes a higher consumption of animal proteins and fats, which is associated with inflammation and aging in the body.
It is important to note where our nutrients come from
A very important one The message of this study is that it is not enough to focus on the nutrients, but it must also be taken into account if they of animal or vegetable origin. Reducing the intake of carbohydrates in the diet and replacing vegetable fat and protein sources results in health benefits. However, these benefits are not respected when they are replaced by sources of animal origin such as meat. (Ash)
