As the saying goes, "food should not be too refined," but in the process of refining, nutrients are lost. In fact, many ingredients we consider "waste"恰恰 contain the nutrients we lack.
People's lives are becoming more and more refined, and this is especially true for their diet. Squeezing oranges into juice, grinding soybeans into soy milk, and mincing fish into fish balls—this process of "removing the coarse and keeping the fine" actually causes many important nutrients to be lost.
You only need to learn a few simple tricks to牢牢 keep these good nutrients.
Fish scale jelly, turning waste into treasure
The scraped fish scales can be made into fish scale jelly. Rinse the fish scales in clean water and drain them. Place them in a pressure cooker, add an appropriate amount of vinegar to remove the fishy smell. For every 250 grams of fish scales, add 400 grams of water. Cook over high heat for 10 minutes, then reduce to low heat and cook for another 20 minutes, until the fish scales turn white and curl, and the soup becomes pasty. Remove the scales and impurities, pour the liquid into a container to set into a jelly, and store it in the refrigerator for a finer texture. When eating, season with salt, soy sauce, vinegar, coriander, and chopped green onions for a cold salad.
Tofu dregs pancake
After making soy milk, the tofu dregs can be used to make pancakes. Tofu dregs can be considered the most nutritious "waste" because it contains a large amount of calcium. In 100 grams of tofu dregs, there are nearly 100 milligrams of calcium, almost equal to the calcium content of milk. In addition, the dietary fiber in tofu dregs is also quite rich. Dietary fiber can promote gastrointestinal motility and has the effect of preventing colon cancer. In recent years, scientists have also discovered that tofu dregs contain more anticancer substance "saponin." Eating tofu dregs regularly can reduce the risk of breast cancer, prostate cancer, pancreatic cancer, and other cancers.
Although nutritious, tofu dregs have a poor texture, which is the main reason people discard them. In fact, with a little processing, tofu dregs can also be delicious. The simplest way is to mix the tofu dregs with salt, flour, eggs, and chopped green onions, and pan-fry them into tofu dreg pancakes. Paired with soy milk, it makes a nutritious and delicious breakfast. In addition, tofu dregs can also be cooked with oatmeal and coconut milk into a sweet and delicious tofu dreg porridge, which can be chilled in the refrigerator for a great dessert.
Pork skin, something women should eat more of
Many people throw away pork skin and fat when cooking meat, believing that eating only lean meat is the healthiest. In fact, pork skin contains extremely rich collagen, and its fat and calorie content are very low. Collagen is important for maintaining the shape of cells and the plasticity of tissues. It can prevent the skin from drying out and dehydration, delay cell aging, and thus play a role in skin care and beauty. Women should eat more of it. Stir-fried pork skin or making pork skin jelly are both good choices.
Eating oranges, don't throw away the orange pith
Between the orange peel and the pulp, there are some white, thread-like substances that are a bit bitter. Many people peel them off completely when eating oranges. In fact, this bitter substance is a nutrient called "rutin." This substance can keep human blood vessels normal elasticity and density, reduce the brittleness and permeability of the vessel walls, and prevent cerebral hemorrhage.
Therefore, elderly people with cardiovascular and cerebrovascular diseases should not throw away the orange pith when eating oranges.
