Walnut has high nutritional value. Especially for middle-aged and elderly people, because the arginine, oleic acid and antioxidants contained in walnuts are beneficial to protect the cardiovascular system and prevent coronary heart disease, stroke and Alzheimer's disease, walnut powder must be selected correctly. High-quality walnut powder is produced with high-quality walnut kernel as the main raw material, while poor-quality walnut powder is mostly prepared with puffed rice, dextrin and essence or dried with soybean and other raw materials. Many inferior walnut powders even contain no walnut raw materials at all. It is not good to eat. Cereal is also a good coarse grain food, which is beneficial to moistening the intestines and relaxing the bowels. You can eat it safely. Others, it is good for the elderly to eat ganoderma lucidum spore powder. My grandfather has been eating. It is good because the polysaccharides, peptides and amino acids in Ganoderma lucidum have a good effect on preventing tumors and fighting cancer. Very suitable for the elderly. This brand has a long history and a good reputation. You can eat it.
