Being full may prevent hunger, but why are an increasing number of people plagued by "seemingly sick but not quite" conditions like limb weakness, back pain, leg soreness, dizziness, and blurred vision after eating? In fact, this is your body's protest because we haven't "eaten enough calcium." So, how can Chinese people be "full from calcium" while also being "full from food"? There are three key points to remember.
The first key is to choose high-calcium foods. First, selecting high-calcium foods is the most effective, simplest, and most economical way to supplement calcium. Calcium-rich foods can be categorized as follows: The first category is milk and dairy products. One bottle of milk per day (about 250 ml) can meet one-quarter of the body's daily calcium requirement. The second category is soybeans and soy products, including soybeans and tofu. The third category is aquatic foods, among which dried shrimp has the highest calcium content. The fourth category is marine plants and fungi, including kelp, nori, and wood ear mushrooms. Additionally, many coarse grains are also high in calcium, such as black sesame and lentils.
The second key is to master scientific methods of calcium supplementation. First, it's best to eat less foods that hinder calcium absorption. For example, although spinach contains a large amount of calcium, its oxalate content inhibits calcium absorption. A high-salt diet can also interfere with calcium absorption. If daily salt intake exceeds 5 grams, the absorption rate of calcium will decrease. In this case, calcium intake should be appropriately increased to meet the body's needs. Secondly, prioritize "dietary supplementation," and special populations can supplement with calcium preparations. This is because the intake of high-calcium foods is constrained by multiple factors. Therefore, for certain special populations, such as children, pregnant women, lactating women, and those allergic to high-calcium foods, they can directly supplement with some calcium preparations or additives to meet the body's special needs for calcium.
The third key is to seize critical periods for calcium supplementation. In younger years, although the body's calcium demand is less than in old age, this period is the golden time for calcium supplementation because the calcium consumed during this time is being stored for a lifetime. Before the age of 30, the body's calcium metabolism is in a positive balance, meaning calcium absorption is greater than loss, and excess calcium continuously deposits in the bones. The more calcium stored during this time, the more will be available for consumption later. However, after the age of 30, the body's bone mass begins to slowly decline after reaching its peak. If the accumulation in the early stages is insufficient, the "bone bank" will be in deficit during old age, leading to problems like osteoporosis and other bone metabolism diseases. Of course, this doesn't mean that calcium supplementation after 30 is futile; it should be a lifelong必修课 (required course).
Despite this, researchers still hope to make milk even more perfect. For example, the Public Nutrition and Development Center of the National Development and Reform Commission, in collaboration with the Mengniu Dairy Group, developed OMP bone-building milk. The OMP (Osteoblast Milk Protein) it contains is a natural active protein found in trace amounts in milk, with a relatively higher content in colostrum. It has a unique mechanism and effect on increasing human bone density. The OMP content in the regular milk we drink is so minimal that it has no significant effect. However, Mengniu uses advanced separation and extraction technology to extract OMP from milk and adds it to its brand "Telunsu." Compared to regular milk, its active milk protein content is multiplied several times, thus improving bone synthesis metabolism, enhancing bone density, promoting bone mass increase, and delaying bone aging.
