XINGFU Walnuts shell is a little bit thick than the other two models, but still can crack by hand, it is a cost effective model from Xinjiang as well, Kernel rate is 50-53%.
Walnuts without shells are 4% water, 15% protein, 65% fat, and 14% carbohydrates, including 7% dietary fiber (table). In a 100-gram reference serving, walnuts provide 2,740 kilojoules (654 kcal) and rich content (20% or more of the Daily Value or DV) of several dietary minerals, particularly manganese at 163% DV, and B vitamins
One published study mentions research indicating that consumption of 75 grams per day of walnuts improved biomarkers of prostate and vascular status in men at risk for prostate cancer. Study authors noted that the food's high tocopherol content was likely a contributing factor for this benefit。
Another study showed the potential for reduced prostate risk when men consumed 35 grams of walnuts per day. While some other animal studies have researched the link between prostate cancer and walnut consumption,strong evidence in humans is lacking.
Other studies have suggested dietary components in walnuts may counter inflammation and therefore the risk for certain cancers. However, those study authors also note that human clinical evidence directly assessing walnuts and cancer risk as a primary outcome is limited.
