It is essential to adjust your diet reasonably to ensure an adequate supply of essential nutrients for the body, thereby enhancing cold tolerance and immune function. But how can you eat healthily and safely?
There are many types of bamboo shoots, categorized by the season they are harvested: winter shoots (dong sun) from winter, spring shoots (chun sun) from spring, and whip shoots (bian sun) from summer. Among them, winter shoots are of the highest quality. January and February are the best months to enjoy them.
Winter shoots are the young buds that grow from the rhizomes of the nan bamboo. They develop in the summer and are harvested in the winter after maturing, which is how they got their name. They are generally grown in mountainous areas in an environment with clean soil, water, and air, and no pesticides are used, making them a very authentic green vegetable. Winter shoots are conical in shape with a yellowish downy outer shell. The best ones are plump, golden in color, have a small base, and are undamaged on the outside. Those with a large base or visible damage are of lower quality. The flesh of the winter shoot is tender, fresh, and crisp, with a pure, clean fragrance. It is as white as jade and has a pure, fresh aroma. It is praised as "golden robe and white jade, unparalleled among vegetables" and "the finest among all vegetable dishes." Not only are winter shoots delicious, but they are also nutritious. They contain a nitrogenous substance that gives them a particularly savory flavor when cooked with various meats.
Winter shoots are considered cooling in nature and sweet in flavor, and are said to have benefits such as "clearing the nine orifices, invigorating blood circulation, resolving phlegm, and promoting digestion." The rich dietary fiber in winter shoots promotes intestinal peristalsis, which aids digestion and helps prevent constipation and colon cancer. They also have certain therapeutic effects for patients with obesity, coronary heart disease, hypertension, diabetes, and arteriosclerosis. However, winter shoots contain a high amount of calcium oxalate, so people with urinary tract stones, gout, hyperuricemia, nephritis, or kidney insufficiency should not eat them in large quantities.
There are many ways to cook winter shoots, such as braising, stir-frying, boiling, stewing, and simmering, all of which can create delicious dishes. When cooked alone, they can make uniquely flavored dishes like oil-braised winter shoots and dry-braised winter shoots. When steamed with chicken or stewed with duck, they impart a very fresh and delicious flavor. Cooking with winter shoots also has its nuances: the tips are tender, crisp, and refreshing, and are best stir-fried with meat; the outer sheaths are thin, soft, and smooth, and are best steamed with meat; the slices are sweet and thick, making them a good accompaniment for stewed dishes. Because winter shoots have the characteristic of absorbing the umami of other foods, they can be cooked with meat, poultry, and eggs, or also combined with bean products and edible mushrooms.
