According to the United Press International, this new study shows that the risk of premature death is not the fat in the diet, too much carbohydrate may be the real death killer, especially refined, processed carbon water. Compound.
The study also found that eating fruits, vegetables, and beans can reduce the risk of premature death, but eating three to four servings a day seems to be enough, and any additional intake does not seem to provide more health benefits.
What does this mean? For example, cheeseburgers are edible, and burgers with lettuce and tomatoes are good for health, but excessive consumption of white flour burger bread may increase the risk of premature death.
Mahshid Dehghan, the lead author of the study and an investigator at the Institute of Population Health at McMaster University in Ontario, points out that high fat intake (about 35% of the daily diet) is compared to people who consume a small amount of fat. The risk of premature death was reduced by 23% and the risk of stroke was reduced by 18%.
The researchers also point out that people with low saturated fat (less than 3% of their daily dietary intake) are at a higher risk of premature death than those who consume more than 13% of saturated fat in their daily diet.
At the same time, a high-carbohydrate diet (an average of 77% carbohydrates) also causes a 28% increase in the risk of premature death compared to a low-carbohydrate diet.
Dehegan pointed out that the results of the study are completely opposite to the current popular concept. Increasing fat intake may actually help reduce the risk of death.
“We have not found any evidence that a state of saturated fat below 10% is good for health, and less than 7% may even be harmful. The right amount of fat, especially when carbohydrate intake is low,†she said. It is the most beneficial to health."
She stressed that the results of this study suggest that some well-known health organizations may need to reconsider their dietary guidelines.
But not everyone supports giving up the current diet guidelines.
Dr. Christopher Ramsden, a clinical researcher at the National Institute of Aging in the United States, believes that the results of this study are still to be considered and are not yet a reference for healthy eating guidelines.
O'Dea, a nutritionist at the Lennox Mountain Hospital in New York, also pointed out that the study did not select specific foods for nutritional analysis, so this is a major drawback from a nutritional point of view. In addition, the study did not consider trans fatty acids, a component that has been shown to seriously affect health and cause cardiovascular disease.
The researchers said that the current global dietary guidelines suggest that 50% to 65% of a person's daily intake of calories should come from carbohydrates, while less than 10% comes from saturated fat. The recommendation also points out that the best diet is to maintain a balance of carbohydrates and fats, that is, about 50 to 55% of carbohydrates and about 35% of fat, including saturated fats and unsaturated fats.
All foods contain three major nutrients that are vital to life: fat, carbohydrates and protein. How people should eat is the focus of debate for decades. Over time, people's diet is also developing from low fat to low carbohydrate.
In this study, Dehgan and her colleagues tracked the diet and health of more than 135,000 people, aged 35 to 70, in 18 countries around the world, and the research team averaged the participants' health status. Track for about seven years, at least once every three years. Researchers hope to show a global perspective on how diets affect health.
Researchers have found that high-carbohydrate diets are commonplace, with more than half of people taking 70% of their daily calories from carbohydrates. High-carbohydrate diets are associated with increased blood cholesterol and cholesterol-induced thrombosis.
Although the experts are still arguing about what is the best diet, people always have to eat. What should they eat? Audi believes that diet should include healthy carbohydrates, protein and lots of fruits and vegetables. Remember to avoid eating processed snacks containing trans fatty acids and saturated fats and choose a healthy source of carbohydrates.
The study was presented at the annual meeting of the European Society of Cardiology in Barcelona, ​​Spain on Tuesday. The Lancet magazine website also introduced this research findings on August 29.
