Think back, in your daily life, do you throw away many things you think are useless? For example, when cooking fish, you discard the fish scales; when eating oranges, you pick off all the pith; when eating spare ribs, you spit out the bones... Don't ever think these things are useless. If you really believe that, then you are being wasteful!
Fish eyes, especially those of tuna, contain a considerable amount of unsaturated fatty acids such as Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (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.
Nutritionists have found that fish scales contain more lecithin, various unsaturated fatty acids, and multiple minerals, especially high in calcium and phosphorus, making them a special health supplement. They have the effects of enhancing human memory, delaying the aging of brain cells, reducing cholesterol deposition on blood vessel walls, promoting blood circulation, and preventing hypertension and heart disease. Additionally, they can prevent rickets in children and osteoporosis and fractures in the elderly.
Many people, after peeling an orange, always tear off the white pith from the surface of the segments. In fact, orange pith contains a vitamin called "rutin," which can help maintain the normal elasticity and density of blood vessels, reduce the fragility and permeability of blood vessel walls, prevent capillary bleeding, and help prevent cerebral hemorrhage in patients with high blood pressure and retinal hemorrhage in diabetic patients. For people who are prone to bleeding, especially the elderly with a tendency for vascular sclerosis, eating orange pith is even more beneficial.
Bone nutrition is superior to meat. Under a microscope, a wall composed mainly of calcium contains countless sponge-like pores, where rich nutrients are stored. Comparing the nutritional components of pig bones with fresh pork, its protein, iron, sodium, and energy produced are far higher than that of fresh meat. Its protein content is 23% higher than milk powder, twice that of pork, 61% higher than beef, and more than double that of an egg. As for 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 are rich in calcium, carotene, various vitamins, and other nutrients. They have a sweet, fresh, and tender taste with a good texture. They can be cooked as a dish alone, stir-fried with meat, or used to make soup. Regular consumption of chili leaves can help expel cold, warm the stomach, nourish the liver, and improve eyesight, as well as aid in weight loss and beauty. Additionally, eating chili leaves in moderation can promote gastric juice secretion, increase appetite, and is suitable for those with a weak stomach, indigestion, bloating, or stomach cold pain.
