Yes, the stems, leaves and buds of germinated buckwheat are edible, but foods like potatoes and sweet potatoes will produce toxins after germination and cannot be eaten.

Buckwheat bulbs are rich in protein, amino acids, soluble sugar, minerals, vitamins and other nutrients, and have certain dietotherapy and health care functions. Buckwheat head has wide adaptability and strong resistance. Its bulbs can be fried, pickled and salted. It is one of the famous health-care agricultural products, known as "Ganoderma lucidum in vegetables", with good shape and taste and unique flavor.

Extended data;

He Wei, a researcher at the National Vegetable Engineering Technology Research Center, pointed out in an interview with the reporter of Life Times that some vegetables can still be eaten after germination, such as garlic, ginger, onion, radish, cabbage and broccoli. Garlic sprouts and grows into green garlic seedlings, which are rich in nutrients such as vitamin C and carotene.

The "new shoots" of cauliflower are rich in carotene, vitamin E and sulforaphane. Radish seedlings are also very nutritious, containing a lot of vitamin K and folic acid. Under the premise of not rotting, this kind of food will not produce toxins when sprouting, and can be eaten normally, but the nutritional value of sprouted food will be reduced to some extent, because it gives some nutrition to "new life".
