1. Many of these drinks are claimed to have the effects of nourishing brain, zinc and antioxidation. In this regard, Yang Wenjiao, a national second-class nutritionist, said that the efficacy of these products can be concluded from the nutritional ingredients marked on them. Taking walnuts as an example, the content of protein in every 100g of walnuts is generally above10g, and the content of walnuts with better quality will be higher. From the nutritional composition table marked on the product, the public can know the composition and nutritional composition of the purchased product. The reporter found that the content of protein in this beverage is about 0.6g/ 100ml, so the content of protein in a can of beverage is generally above10g, which is close to the content of protein in a walnut.
2. Some products claim to have the function of supplementing zinc. Among nuts, walnuts and almonds have higher zinc content, and both of them have the function of supplementing zinc. When manufacturers produce drinks such as walnut dew or almond dew, they all include the process of grinding nuts. The ingredients in walnuts and almonds, including protein, zinc and unsaturated fatty acids, are also included in the drinks. Consumers can see from the food ingredient list that the zinc content of good quality walnuts can reach 6.42g/ 100g or even higher. From the content of protein in the beverage ingredient list, it can be inferred that the zinc content is not high, and more nutrition can be obtained by eating walnuts and almonds directly. Therefore, its claimed functions of nourishing brain, zinc and antioxidation are limited. When choosing this kind of drinks, people should not have too high expectations for zinc supplementation, brain strengthening and other functions.
