Most people's understanding of a light diet is to eat more light fruits and vegetables and avoid meat. In fact, a light diet doesn't mean only drinking congee and eating vegetables without any animal-based foods. It refers to using less oil and salt when cooking, and ensuring a balanced intake of nutrients. The necessary meat should still be included in the diet.
Protein is a substance essential for the human body. A healthy adult should drink a glass of milk and eat an egg every morning, consume five to six liang (about 250-300g) of staple food per day, and also have two to three liang (about 100-150g) of meat daily. For example, one liang (about 50g) should be from soy products and two liang (about 100g) from animal meat. In short, the required amount of protein must be met.
If you really don't want to eat meat like pork, you can choose some refreshing, easy-to-digest, and absorb beans, fish, and dairy products. For instance, drink an appropriate amount of yogurt or milk, and prepare dishes like steamed fish, braised tofu, or salted duck. Additionally, if elderly people dislike eating meat due to their age, they can opt for all-formula nutritional powders and other nutritional supplements to provide the body with essential nutrients like protein and vitamins.
Special attention should also be paid to balancing oil and salt when cooking. For example, if you cook a braised fish dish, you can pair it with a cold-dressed vegetable dish. If the braised fish uses a lot of oil, the cold-dressed vegetable should use relatively less oil, in order to control the total daily intake of oil and salt.
