Walnuts, as a common nut food in daily life, have no significant therapeutic effect on gallstones. There are many types of gallstones, which can be categorized into cholesterol gallstones, bile pigment gallstones, mixed gallstones and so on according to their main components. The reasons for the formation of gallstones are also various, such as high oil and high fat diet, obesity and so on. Therefore, consuming walnuts not only fails to abate gallstones, but after consuming them in large quantities, it may also induce the formation of gallstones due to the rich fat it contains. It is recommended that people suffering from gallstones try to stick to a light diet in their daily life and reduce the intake of high-fat and high-sugar foods such as fried chicken, pig’s trotters, cakes, and so on. If symptoms such as biliary colic occur, consult a doctor in time to avoid irreversible consequences due to delayed treatment.
