Research: Excessive-fiber weight loss plan linked to diminished threat of dementia

Japanese researchers followed more than 3500 men and women aged 40 to 64 for two decades and found that those who ate more fiber, especially soluble fiber, had a reduced risk of developing the disease. dementia. Researchers suggest that fiber is not only beneficial for our heart health, but also for the brain.

Based on Science everydayThe study was published in the journal Nutritional Neuroscience.

Lead author Dr. Kazumasa Yamagishi said: “Dementia is a dangerous disease that often requires long-term care. “We are interested in some recent studies showing that fiber may play a preventive role. We investigated this using data collected from thousands of adults in Japan for a large study that began in the 1980s.”

The researchers divided the participants into four groups depending on the amount of fiber in their diets. They found that the groups that ate the most fiber had a lower risk of dementia. They also found that people who ate more soluble fiber found in foods like oats and legumes than insoluble fiber found in whole grains and vegetables, were more protective against obesity. stronger dementia.

Yamagishi speculates that perhaps soluble fiber in the gut reduces neuroinflammation and plays a role in the onset of dementia, ScienceDaily reports. Or, maybe fiber can reduce other risk factors for dementia, such as body weight, blood pressure, lipids, and sugar levels.

Insoluble fiber is not absorbed through the body Dr. Gabe Mirkin. He adds that a high-fiber diet, rich in foods containing soluble fiber, promotes the growth of healthy bacteria in the gut that produce short-chain fatty acids, or SCFAs. These SCFAs help reduce inflammation, which is associated with damage to brain cells and other tissues as part of the aging process.

“Aging is associated with increased loss of brain function, and more than 30 percent of North American adults over the age of 65 have dementia,” explains Mirkin. “This loss of brain function may be related to the way that aging changes the composition of the bacteria in your colon. As people age, the number of different colonic bacteria decreases markedly and gradually increases. The loss of bacterial diversity has been linked to an increased risk of brain damage, such as dementia, Alzheimer’s disease and Parkinson’s disease. “

Mirkin adds that a low-fiber Western diet significantly reduces the number of different types of bacteria in your colon, but a change in diet can rapidly increase diversity. The form and quantity of colon bacteria are beneficial for health at any age, even when a diet is low in fiber. have been followed for a long time.

“Your current diet determines what kind of bacteria live in your gut,” says Mirkin. Even if your colon is full of harmful bacteria, you can change your colon bacteria by switching to a high-fiber diet that includes a variety of vegetables, whole grains, beans, nuts, and seeds. other. A healthy diet, along with weight control, a regular exercise program and avoiding alcohol and smoking will help protect your brain from dementia and many other related diseases. to the typical Western diet and lifestyle”.
