Researchers discovered particularly high levels of antioxidants in walnuts

Because of their content of vitamins, minerals, protein, fiber and unsaturated fatty acids, nuts have long been proven to be health-promoting. In several studies, their antioxidant content was also found to have a positive effect on the cardiovascular system and blood vessels.

Now American scientist Joe Vinson from the University of Scranton (Pennsylvania, USA) has found that walnuts have the highest antioxidant content among nuts. Walnuts contain about twice as much antioxidants as other nuts and, moreover, the antioxidants of walnuts are particularly effective in binding free radicals, emphasized Joe Vinson. The protection against cell damage and the health-promoting effect is therefore particularly high for walnuts, the US scientist reported on the “24th National Meeting & Exposition of the American Chemical Society ”.

Antioxidants prevent numerous diseases As part of his study, the University of Scranton researcher examined the antioxidant content of nine different types of nut. When comparing almonds, pecans, peanuts, pistachios, hazelnuts, Brazil nuts, cashew nuts, macadamia and walnuts, walnuts had the highest levels of antioxidants, said Joe Vinson. In addition, not only is the amount of antioxidants in the walnuts significantly higher, but they are also much more effective in binding free radicals, the US scientist emphasized. According to the expert, the walnut substances are, for example, two to fifteen times more effective than vitamin E, which is considered to be a general cell protector because of its anti-inflammatory effect. Older studies have already clearly demonstrated scientifically that eating small amounts of nuts or peanut butter significantly reduces the risk of heart disease, certain types of cancer, gallstones, type 2 diabetes and other health problems. The antioxidants were always said to have a particularly health-promoting effect. In view of his own research results, Joe Vinson comes to the conclusion that the consumption of seven walnuts a day is enough to benefit them considerably in terms of health.

Health-promoting effects of nuts not sufficiently known The US scientist denied the widespread concern that eating healthy but also high-calorie nuts increases the risk of obesity, and referred to a study from 2009 that had shown that the Consuming nuts reduces the risk of gaining weight and being overweight rather than increasing. In addition, the fats contained in nuts are healthy and are not suspected of clogging the arteries. Nevertheless, the expert advises keeping the quantities of nuts consumed rather low. However, this should not be particularly difficult for nut lovers since nuts are as filling as they are high in calories. For the US researcher, from a health standpoint, nut consumption would still be significantly expandable, because residents in modern industrialized countries have so far only obtained around eight percent of the antioxidants consumed daily from nuts. The expert suspected that the health-promoting effects of the nuts were not sufficiently known. Vinson attributed the fact that the antioxidants of the walnuts work particularly efficiently, because they are not roasted before consumption, so that all ingredients are preserved. Another advantage of the nuts as a whole is that they are lactose and gluten-free, the US researcher emphasized.

Vegetables and fruits that contain antioxidants The cell-protecting, anti-inflammatory and cancer-preventing function of antioxidants has been known for a long time in medicine, although in naturopathy, for example, onions, turmeric and cranberries have always been considered “natural antibiotics” due to their antioxidant content. be used. Other types of fruit and vegetables that contain natural antioxidants and can have a positive effect on health include mangoes, grapes, garlic, broccoli, ginger, coffee, tea, parsley, whole grain rice, tomatoes and asparagus.
