Vinegar is a staple in every household's cooking. Adding the right amount of vinegar not only serves a disinfecting purpose but also makes dishes more vibrant in color. So, what are the benefits of adding vinegar when cooking?
First, adding vinegar during cooking can increase appetite. This is especially beneficial for the elderly who may have a poor appetite. In cold dishes, a little vinegar makes them crisp and refreshing while also stimulating the appetite.
Second, vinegar acts as a "catalyst." Adding vinegar when cooking can make the chemical structure of water-soluble vitamins and Vitamin C in food more stable, preventing them from being destroyed by heat and thus preserving the nutritional value of the food. Additionally, vinegar can dissolve plant fibers and animal bones. When cooking fish, stewing meat, or braising pork ribs, adding some vinegar can dissolve the calcium, making it easier for the body to absorb and preventing osteoporosis in the elderly.
Again, for the elderly who suffer from hypertension, vinegar can be a substitute for salt, effectively reducing sodium intake and helping to control blood pressure. Moreover, after being absorbed by the body, vinegar can promote fat breakdown, prevent cholesterol-like substances from depositing on blood vessel walls, and also plays a role in preventing cardiovascular diseases in the elderly.
Finally, from the perspective of Traditional Chinese Medicine, vinegar is sour, bitter, and warm in nature, with effects such as dispelling stasis, detoxifying, and killing parasites. It is also effective for improving the acidic environment of the stomach and inhibiting the reproduction of harmful bacteria.
Elderly individuals should pay special attention to how they consume vinegar. It should not be drunk directly but should be added to dishes. Because vinegar is acidic, undiluted consumption can damage the gastric mucosa, causing acute gastritis and stomach ulcers, and in severe cases, it might even lead to major bleeding in the upper digestive tract.
However, when cooking carrots and green vegetables, vinegar should be avoided. Heating accelerates the chemical reaction between acetic acid and the nutrients in the vegetables. For example, the carotene content will decrease, and chlorophyll will be broken down by the action of acetic acid.
