From 1985 to 2016
, scientists analyzed
the health status of almost 14 thousand people. Each study participant was asked to fill out a questionnaire, where he had to answer about the consumption of 66 products. Researchers counted how much each participant consumed carbohydrates daily and how many calories received from carbohydrates (also daily). American guidelines recommend eating so that carbohydrates make up 45-65 percent of the daily calories.
Then, the researchers divided the participants into three groups: those who consumed few carbohydrates (less than 44.
8 percent of the daily calories), those who consumed a moderate amount of carbohydrates (44.8-52.4 percent), and those who consumed a lot of carbohydrates (over 52.4 percent).
Participants who consumed little carbohydrates were most likely to develop atrial fibrillation (the most common type of arrhythmia): they had a 18% higher risk of developing this disease than those who moderately consumed carbohydrates, and 16% higher than those who consumed a lot of carbohydrates.
With this disease, the heart does not always beat as it should, which can lead to heart palpitations, dizziness and fatigue. People with atrial fibrillation have a five-fold higher risk of developing stroke than people without this condition. In addition, atrial fibrillation can lead to heart failure.
According to one of the authors of the study, there are several explanations why the restriction of carbohydrates can lead to atrial fibrillation. One of them is that people on a low-carb diet tend to eat less vegetables, fruits, and grains, products that have anti-inflammatory effects.
If you exclude these products from the diet, there is a risk of inflammation, which may be associated with atrial fibrillation. Another possible reason is that consuming large amounts of protein and fat instead of carbohydrate-rich foods can lead to oxidative stress, which can also contribute to this heart disease.
For 21 years, scientists have diagnosed atrial fibrillation to nearly 1,900 participants (almost 14,000 people took part).
This large study is considered the first to evaluate the relationship between carbohydrate intake and atrial fibrillation (the most common type of arrhythmia). It is important to understand that although this study shows the relationship between low carbohydrate intake and the development of heart disease, it does not prove cause and effect.
To be sure of this, more research is needed.
Low-carb diet (or keto diet)
that 70-80 percent of calories should be obtained from fats, twenty percent - from proteins and five percent - from carbohydrates. It is believed that with this approach, ketosis is launched in the body - a process in which carbohydrate starvation of cells occurs.This, in turn, leads to weight loss, since it is fat that is burned - it is used as the main source of energy. The consumption of carbohydrates in large quantities is unacceptable in this diet - they contribute to the production of glucose, which is used as energy.
You can eat meat, greens, most vegetables, fatty dairy products, nuts, seeds, avocados, berries, vegetable oils, such as coconut, on a keto diet. On a keto diet, you can’t eat grain, including rice and wheat, sugar, including honey and maple syrup, most fruits, potatoes.
Despite the effectiveness of the diet, it also has contraindications. Before you begin to adhere to it, consult with your doctor.
