Think about it, in your daily life, do you throw away a lot of things you consider useless? For example, throwing away fish scales when cooking fish, picking off all the white pith from oranges when you eat them, spitting out bones when eating pork ribs...
Everyone, please don't think these things are useless! If you really think so, then you are being terribly wasteful!
Fish eyes: Fish eyes, especially those of tuna, contain quite a rich amount of unsaturated fatty acids such as DHA and EPA. This natural substance can enhance brain memory and thinking ability, and is greatly beneficial for preventing memory decline, high cholesterol, high blood pressure, and many other diseases.
Orange pith: Many people, after peeling an orange, always tear off the white pith from the surface of the segments until it's completely clean. In fact, orange pith contains a vitamin called "rutin," which can keep human blood vessels normal in elasticity and density, reduce the brittleness and permeability of blood vessel walls, prevent capillary bleeding, and prevent cerebral hemorrhage in hypertensive patients and retinal hemorrhage in diabetic patients. For people who have a tendency to bleed, especially the elderly with a tendency for vascular sclerosis, eating orange pith is even more beneficial.
Bones: The nutrition in bones is superior to that in meat. Under a microscope, countless sponge-like pores are found within a tube wall mainly composed of calcium, where rich nutrients are stored. Comparing the nutritional composition of pig bones with fresh pork, its protein, iron, sodium, and energy produced are far higher than fresh meat. Its protein is 23% higher than milk powder, twice that of pork, 61% higher than beef, and more than one time that of an egg. As for its phosphorus and calcium content, it is incomparable to other foods. What's particularly valuable is that its nutrients are more easily absorbed by the human body than plant-based foods.
Chili leaves: Chili leaves are rich in calcium, carotene, various vitamins, and other nutrients. They have a sweet, fresh, and tender taste and are very palatable. They can be cooked as a dish alone, stir-fried with meat, or used to make soup. Regular consumption of chili leaves can have the effects of dispelling cold, warming the stomach, nourishing the liver, improving eyesight, and aiding in weight loss and beauty. In addition, eating a moderate amount of chili leaves can also promote gastric juice secretion, increase appetite, and is suitable for those with a weak stomach, indigestion, bloating, and stomach cold pain.
