Calcium rich foods keep bone strong - nutrition geriatrics
Calcium is an essential mineral for the health of our bones. It is essential not only for bones, but also for the proper functioning of the heart, muscles and nerves. As we age, maintaining a calcium-rich diet becomes more crucial to avoid diseases such as osteoporosis. In this article, we will explore the most calcium-rich foods and how to incorporate them into your daily diet to ensure you keep your bones strong.
Why is calcium important?
Calcium is the main component of bones and teeth. Approximately 99% of the calcium in the human body is stored in the bones and teeth, while the remaining 1% circulates in the blood for critical functions, such as blood clotting and muscle contraction. If you don't consume enough calcium, your body will begin to draw calcium from your bones, which can lead to their weakening over time.
Main sources of calcium
- Dairy: Dairy products are one of the best sources of calcium available. An 8-ounce glass of milk can provide about 300 mg of calcium, which is about 30% of the recommended daily intake. Products such as cheese and yogurt are also rich in this mineral. Opting for low-fat or fat-free versions can provide the same benefits without adding extra calories.
- Green leafy vegetables: Green leafy vegetables such as kale, bok choy and spinach are also excellent choices for those looking to increase their calcium intake. For example, one cup of cooked kale can provide about 100 mg of calcium. However, it is important to note that some vegetables such as spinach contain oxalates, which can inhibit calcium absorption, so they should not be the only source of calcium.
- Fortified foods: Many common foods today are fortified with calcium, such as orange juices, cereals, and plant-based milks [such as almond and soy]. These fortified foods are an excellent choice, especially for people who follow a vegan diet or have a dairy intolerance.
- Fish: Fish such as sardines and canned salmon [with bones] are rich in calcium. These fish also contain omega-3 fatty acids, which help improve overall bone health. One serving of sardines can provide more than 300 mg of calcium.
- Nuts and seeds: Almonds and chia seeds are another important source of calcium. A handful of almonds [about 23 pieces] can contain about 75 mg of calcium, while chia seeds not only provide calcium, but also other nutrients such as magnesium, which is also crucial for bone health.
How to improve calcium absorption
It's not enough to consume calcium-rich foods, it's also important to make sure your body can absorb it properly. Vitamin D is key in this process, as it facilitates calcium absorption in the intestine. You can get vitamin D from sun exposure, fortified foods or supplements.
Another factor to keep in mind is to avoid excessive consumption of certain foods that can interfere with calcium absorption, such as sodium-rich foods and carbonated beverages.
Tips for a calcium-rich diet
- Start the day with a calcium-rich breakfast, such as a bowl of yogurt with nuts or a glass of milk with fortified cereal.
- Incorporate leafy green vegetables into your daily meals, either in salads or as a side dish.
- Add sardines or salmon to your main dishes at least once a week.
- Use fortified milks instead of regular milks if you are dairy intolerant.
- Snack on almonds or chia seeds, which not only provide calcium, but also healthy fats.
Conclusion
Maintaining a calcium-rich diet is critical to maintaining strong bones throughout life. Incorporating foods such as dairy, leafy green vegetables, nuts and fish can make a big difference in your bone health. Also, don't forget to supplement your calcium intake with enough vitamin D to improve its absorption. Making these small adjustments to your daily diet can help you avoid bone problems in the future and maintain a strong, healthy body.
