Drink black rice and spinach porridge if your nails are thin.

Black Rice Porridge

Many elderly friends have brittle and non-flexible nails that are prone to splitting and breaking. This is due to a deficiency of minerals and B vitamins in the body. Consuming black rice and spinach porridge can effectively prevent and treat this condition. Black rice not only contains high-quality protein needed for nail regeneration but is also rich in minerals such as zinc, copper, calcium, and iron, which nourish the nail surface to prevent it from becoming brittle, thin, and peeling. Spinach is rich in various B vitamins and selenium, which help nails effectively use oxygen and promote the rapid metabolism and renewal of damaged nails. Take 100 grams of black rice (soaked for 8 hours), add water to cook into a porridge. After it's cooked, add 100 grams of chopped spinach and simmer for a short while. Consume in the morning and evening, every other day, for three consecutive weeks.
