Calcium supplementation has become a conscious practice for many people, leading numerous women to regularly take calcium supplements as health aids. Beyond selecting appropriate calcium supplements, factors like adequate sun exposure, balanced nutrition, and proper cooking methods are equally crucial. Many everyday foods serve as calcium sources. Here are some calcium-rich foods to consider.
As research into calcium deepens, over 120 diseases have been found to be closely linked to calcium deficiency in their onset and progression. Therefore, we must consume more healthy foods that aid calcium supplementation.
Milk and Dairy Products: Cow's milk, goat's milk, and their powdered forms; cheese; yogurt; condensed milk.
Legumes and bean products: Soybeans, edamame, lentils, broad beans, tofu, dried tofu, tofu skin, fermented tofu, etc.silver carp, loach, shrimp, dried shrimp, crab, kelp, laver, clams, sea cucumber, snails, etc. Meat and poultry: Lamb, pork brain, chicken, eggs, duck eggs, quail eggs, preserved eggs, pork floss, etc.
Vegetables: Celery, Chinese cabbage, carrots, radish greens, sesame seeds, cilantro, snow peas, black fungus, mushrooms, etc.
Fruits and Dried Fruits: Lemons, loquats, apples, black jujubes, dried apricots, dried tangerine peel, dried peaches,almonds, hawthorn, raisins, walnuts, watermelon seeds, pumpkin seeds, dried mulberries, peanuts, lotus seeds, etc.
Special Notes:
Proper food preservation minimizes calcium loss. Avoid stirring milk while heating. Add ample water when stir-frying and keep cooking time brief. Avoid chopping vegetables too finely.Spinach, water chestnuts, and leeks contain high levels of oxalic acid. Soak them briefly in hot water to dissolve oxalic acid, preventing it from binding with calcium-rich foods to form insoluble calcium oxalate. Lactose helps retain dietary calcium. Whole grains like sorghum, buckwheat, oats, and corn contain more calcium than rice or wheat flour. Incorporate whole grains into your diet regularly.
Generally, consuming yogurt between 30 minutes to 2 hours after a meal yields optimal results. Under normal conditions, gastric pH ranges between 1 and 3. On an empty stomach, gastric acidity is below pH 2, unsuitable for the growth of yogurt's active lactic acid bacteria. Only when gastric pH rises can yogurt's lactic acid bacteria proliferate fully, promoting health.Approximately two hours after a meal, gastric acid is diluted, raising the pH to 3–5. Consuming yogurt at this time maximizes nutrient absorption.
Additionally, drinking yogurt on an empty stomach may stimulate rapid gastrointestinal emptying, causing nutrients to be expelled before complete digestion and absorption. Post-meal consumption reduces this stimulation, allowing yogurt to be gradually absorbed in the stomach.
Drinking milk at night maximizes calcium absorption
Yogurt is an excellent dietary source of calcium. From a calcium supplementation perspective, consuming yogurt in the evening offers greater benefits. This is because blood calcium levels are lowest between midnight and early morning, creating an optimal environment for calcium absorption from food. Simultaneously, fewer factors interfere with calcium absorption during this timeframe.
While milk also contains high calcium levels, the lactic acid in yogurt binds with calcium to enhance absorption more effectively. However, remember that certain bacteria and acidic substances in yogurt can damage teeth. Always brush your teeth promptly after consuming yogurt at night.
