Those who consume walnuts have a lower risk of type 2 diabetes
A study by US researchers has shown that people who consume walnuts have a significantly lower risk of type 2 diabetes compared to people who do not eat nuts.
Rich in healthy vitamins and minerals
According to experts, nuts are a healthy addition to the diet and can protect against serious illnesses. Above all, the “Queen of Nuts”, the walnut, has many health benefits. It contains plenty of vitamins E and B6, minerals (especially magnesium), fiber and valuable secondary plant substances. In addition, walnuts contain by far the most essential omega-3 fatty acids of all types of nuts. And, according to a study, walnuts appear to lower the risk of type 2 diabetes.
Health benefits confirmed in studies
With 63 percent fat and a calorie content of 670 kilocalories per 100 grams, walnuts are high in energy, but also very healthy.
According to health experts, regular consumption of this type of nut lowers “bad” LDL cholesterol and prevents cardiovascular diseases.
Numerous scientific studies have shown that walnuts protect health.
For example, scientists at Louisiana State University (USA) found that walnuts can promote intestinal health and prevent colon cancer.
They can also help against rheumatic diseases thanks to the anti-inflammatory omega-3 fatty acids they contain.
And years ago, a study was published in the "Federation of American Societies for Experimental Biology", the "FASEB Journal", according to which walnuts can offer protection against type 2 diabetes despite their high fat content.
California researchers came to a similar conclusion in a recent study.
Reduced risk of type 2 diabetes
As part of the study, researchers at the David Geffen School of Medicine at the University of California, Los Angeles, analyzed data from 34,121 adults aged 18 to 85.
The National Health and Nutrition Examination Survey (NHANES) asked these people about their eating habits, whether they were diagnosed with diabetes, or whether they were taking medication for diabetes.
The evaluation showed that people who consumed walnuts had a significantly lower risk of diabetes than those who did not eat walnuts.
According to the information, the average intake among walnut users was approximately 1.5 tablespoons per day. The doubling of walnut consumption (three tablespoons) was associated with a 47 percent lower prevalence of type 2 diabetes.
According to the scientists, this amount of walnuts is close to the recommended serving size of four tablespoons.
The researchers' results were published in the journal "Diabetes / Metabolism Research and Reviews" (Diabetes Metab Res Rev).
No causality has been demonstrated
"These results provide further pointers for food-based instructions to reduce the risk of diabetes," explains study author Dr. Lenore Arab in a communication from the California Walnut Commission that funded the study.
"The strong connection that we see in this study between walnut users and lower prevalence of type 2 diabetes is an additional reason for the inclusion of walnuts in the diet," said the scientist.
"Other studies have shown that walnuts can also be beneficial for cognitive functions and heart health."
However, the communication also points out that participants in the newer study were asked about their eating habits over the course of a day or two, which may not be representative of common consumption patterns.
In addition, the study was unable to prove causality. (ad)
