1. which foods contain large amounts of calcium?
There are a variety of foods that contain large amounts of calcium. Here are some examples:
1. milk and dairy products: Milk is an excellent source of calcium. A glass of milk (240 ml) contains about 300 mg of calcium. Yogurt and cheese are also rich in calcium. Greek yogurt and hard cheeses such as cheddar or parmesan contain particularly high amounts.
2. green leafy vegetables: vegetables such as kale, broccoli, spinach and pak choi are rich in calcium. One cup of cooked kale contains about 200 mg of calcium, while one cup of cooked broccoli provides about 60 mg of calcium.
3. legumes: beans, lentils and chickpeas are not only a good source of protein, but also contain significant amounts of calcium. One cup of cooked white beans contains about 175 mg of calcium.
4. fish: certain types of fish are rich in calcium. For example, a can of sardines (85 g) contains about 350 mg of calcium. Salmon and mackerel are also good sources of calcium.
5. nuts and seeds: Almonds, sesame seeds, and chia seeds are rich in calcium. One ounce (28 g) of almonds contains about 75 mg of calcium, while two tablespoons of sesame seeds provide about 180 mg of calcium.
6. soy products: Tofu, tempeh, and soy milk, which are fortified with calcium, are good plant sources of calcium. Half a cup of tofu contains about 250 mg of calcium.
7. Cereals and grain products: Some cereals and grain products such as oatmeal, amaranth and quinoa also contain calcium. Note, however, that the amount of calcium in grain products is usually lower than in the foods mentioned above.
2. What exactly is calcium?
Calcium is a vital mineral that plays a central role in the body. It is the most abundant mineral in the human body and accounts for about 1-2% of body weight. Calcium is not only important for building and maintaining bones and teeth, but also performs a variety of other vital functions. Most of the calcium in the body is actually found in the bones and teeth. Here it is responsible for strength and structure. Calcium ensures that bones are strong and resilient and do not break easily. It also allows muscles to contract and relax. This applies not only to skeletal muscles, but also to muscles in organs such as the heart. In addition, calcium plays an important role in blood clotting by participating in the activation of clotting factors. It also supports communication between nerve cells and is essential for the transmission of nerve signals. Calcium is involved in the release and transport of neurotransmitters, which are responsible for signal transmission in the brain. Another important aspect is the regulation of acid-base balance in the body. Calcium ions can act as a buffer and help maintain the pH in the blood. They neutralize excess acids and contribute to the stability of the internal environment. Calcium is mainly absorbed through food. Dairy products such as milk, yogurt and cheese are particularly rich in calcium. However, some green vegetables such as broccoli, kale and spinach also contain appreciable amounts of calcium. In addition, calcium is sometimes added to certain foods such as juices or cereal products. For calcium to be effectively absorbed and used by the body, vitamin D is necessary. Vitamin D promotes calcium absorption in the intestines and helps it to be stored in the bones. Therefore, an adequate supply of vitamin D is critical for calcium supply. It is important to note that the body not only absorbs calcium, but also excretes it. Excess calcium is excreted in the urine via the kidneys, which regulates the calcium level in the body.
3. what happens in case of calcium deficiency?
Calcium deficiency, also called hypocalcemia, can have several effects on the body. Calcium is an essential mineral that is important for many biological processes in the body. Therefore, a deficiency of calcium can lead to a number of symptoms and health problems. Here are some possible effects of calcium deficiency:
- Weakening of bones: Calcium is a major component of bones and teeth. A deficiency of calcium can lead to a decrease in bone density and increase the risk of osteoporosis and bone fractures. Bones may become weaker and more brittle.
- Muscle problems: calcium is critical for muscle contraction and relaxation. Calcium deficiency can cause muscle spasms, especially in the calves or neck. Muscle twitching and numbness in the extremities may also occur.
- Increased risk of cardiovascular disease: Calcium plays an important role in regulating heart rhythm and contraction of the heart muscle. Calcium deficiency may increase the risk of cardiac arrhythmias, hypertension, and coronary artery disease.
- Nerve problems: calcium is essential for the transmission of nerve signals. A deficiency of calcium can lead to disruptions in nerve conduction and cause symptoms such as tingling, numbness, muscle twitching and even seizures.
- Problems with teeth and gums: Calcium is also important for dental health. A calcium deficiency can lead to increased susceptibility to tooth decay, gum disease and tooth loss.
- Hormonal changes: Calcium plays a role in regulating hormones such as parathyroid hormone and vitamin D, which are responsible for calcium metabolism in the body. A deficiency of calcium can lead to hormonal imbalances and affect calcium absorption and release.
4. calcium in the form of dietary supplements
If you want to increase a calcium level that is too low with a dietary supplement, you should definitely pay attention to the form of the active ingredient and its origin. Calcium capsules are particularly suitable for increasing calcium levels. They are very well tolerated and are utilized by the body to a high degree. Likewise, the preparation should not contain any chemical additives. If you buy a preparation from Germany, you can be sure that the product has also been produced safely and is of high quality.

5. conclusion: Which foods contain large amounts of calcium?
In summary, calcium is an extremely important mineral for the body. It plays a crucial role in building and maintaining strong bones and teeth. In addition, calcium is essential for muscle function, nerve transmission, blood clotting and maintaining a healthy cardiovascular system. Adequate calcium levels in the body are of great importance for health at every stage of life, from childhood through adulthood and old age. Adequate calcium intake through a balanced diet that includes calcium-rich foods is the best way to meet the body's needs. It is important to note that calcium should not be considered in isolation. The absorption of calcium is influenced by factors such as vitamin D, magnesium and hormones. Therefore, in addition to adequate calcium intake, it is advisable to ensure a balanced overall nutrient supply.
