Nuts reduce the growth of breast tumors


MADRID– New research from Marshall University (USA) has identified nut consumption as a factor that could reduce the growth of breast cancer in mice. Specifically, consumption of 57 grams of nuts per day for about two weeks significantly altered gene expression in already confirmed tumors, Europa Press reported.

In this first two-arm pilot study, published in the journal Nutrition Research, women with breast lumps large enough to perform biopsies were recruited and randomly assigned to groups that consumed nuts or control groups. . Immediately after the biopsy, the women in the nut group began to consume 57 grams daily until the follow-up surgery.

Pathological studies have confirmed that the swellings were breast cancer in all women who remained in the study. At surgery, approximately two weeks after the biopsy, additional samples of the tumors were taken.

The RNA sequencing profile revealed that the expression of 456 genes identified was significantly modified in the tumor due to the consumption of nuts.

"These results support the hypothesis that, in humans, nut consumption may suppress the growth and survival of breast cancers." Further research would be needed through a large-scale study to clinically confirm that its consumption actually reduces the risk of breast cancer or recurrence, "explains W. Elaine Hardman, a professor in the Department of Biomedical Sciences at Joan C. Edwards College of Medicine. Marshall University.

Other studies have linked nut consumption to other health benefits. For example, a systematic review of 26 clinical trials from Harvard University suggests that walnut-enriched diets can significantly reduce total cholesterol, "bad" cholesterol, triglycerides, and apolipoprotein B.

In addition, other research has shown that walnuts help control weight thanks to its high content of unsaturated fats, according to a study published in the Journal of the American Heart Association. Eating a diet that contains unsaturated fats, such as nuts, has similar weight-loss effects to a low-fat, high-carbohydrate diet.

On the other hand, according to an article from the University of California, Los Angeles (USA), those who eat nuts can halve the risk of developing type 2 diabetes compared to those who do not consume them.

After assessing more than 34,000 adults, consumption of 3 tablespoons of nuts per day was associated with a decrease in the prevalence of type 2 diabetes by 47%. This amounts to almost the recommended ration, which is equivalent to 4 tablespoons or 30 grams per day.
