A diet high in sugar and processed foods can have negative long-term health effects. One of the most obvious is the way our bodies respond to exercise.
People with consistently high blood sugar are less likely to benefit from exercise, according to a new study on nutrition, blood sugar and exercise. In addition, another study also showed that eating a diet high in sugar and processed foods affects blood sugar control, has long-term effects on health and causes the body to change the way it responds. with exercises.
People with hyperglycemia tend to be overweight and obese and face an increased risk of heart disease and type 2 diabetes.
Most previous studies on blood sugar and exercise have been epidemiological, meaning that researchers have identified a link between the two conditions but have yet to find definitive proof.
According to a new study recently published in the journal Nature Metabolism, researchers at the Joslin Diabetes Center in Boston and other institutions raised blood sugar levels in mice and saw what happened when they do exercise.
Do research on mice
The researchers started with adult mice. First, they divided the mice into three groups, one on a normal diet, the other on a diet high in sugar and saturated fat, like the common human diet in today’s society. . With this diet, the mice quickly gained weight and blood sugar levels rose as well.
In the other group of mice, the scientists injected a substance that reduced the production of insulin (a hormone that helps control blood sugar), similar to when people have diabetes. The mice did not gain weight, but their blood sugar increased to about the same as the mice in the group that ate the high-sugar diet.
The group of mice with high blood sugar had a much lower running time
After four months, the scientists tested them by measuring their running time. They then put a wheel in each cage and let them run as they wanted for the next six weeks. On average, each rat ran about 482km in a period of 1.5 months.
The training results of the three groups of mice were completely different. The group on a normal, low-sugar diet were able to run for a long time before becoming exhausted, while the high-blood sugar group of mice had a much lower running time.
To better understand why, the scientists conducted muscle analysis. The animal’s muscles will consist of healthy muscle fibers and a network of blood vessels to transport oxygen to fuel these muscle fibers. But the muscle tissues of mice with high blood sugar had a type of collagen that coagulated blood vessels and prevented the muscles from adapting to exercise.
Human study on how blood sugar affects exercise performance
After conducting the study with mice, the scientists conducted a study on blood sugar and endurance of 24 young adults. Of these 24 people, none had diabetes, but some had blood sugar levels that were considered pre-diabetes. When exercising on the treadmill, young adults with poor blood sugar control had the lowest endurance. And when the scientists examined the young men’s muscle tissues microscopically after exercise, they found proteins that could inhibit growth during exercise.
Regularly eating foods high in sugar can actually negatively affect exercise results
In addition, these findings also suggest that high or low blood sugar will depend on diet. When you intend to exercise to lose weight or exercise, in addition to maintaining regular exercise, you also need to limit your intake of products containing a lot of sugar, fat, and processed foods to avoid these foods. This product affects training results.
In addition, the results of these studies also emphasize the role of both diet and exercise in maintaining good health. Both of these two factors have a great influence and relationship with each other, if you want to improve your health but you only exercise but eat “free” foods high in sugar, you will never be able to see it. The result is as good as we expected.
The most special feature of the study was that the rats had hyperglycemia, although their endurance was very low at the beginning of the exercise, but after a while, they also gradually controlled their blood sugar better. This suggests that with the time and determination, regular exercise will help people with hyperglycemia stabilize blood sugar levels and gradually improve their fitness.
