Green vegetables
Collard greens are one of the most calcium-rich vegetables, with about 232 mg of calcium per 100 grams. According to the American Journal of Clinical Nutrition, collard greens are not only rich in calcium, but also contain vitamin K, which aids in blood clotting and increases bone density.
Kale
Kale, also known as the “king of greens,” contains about 150 mg of calcium per 100 grams. Kale has a higher calcium absorption rate than milk, thanks to the low oxalate content of this vegetable.
Spinach
Spinach is a popular source of calcium, with about 99 mg of calcium per 100 grams. However, the National Osteoporosis Foundation notes that spinach contains oxalates, which can reduce calcium absorption.
Therefore, this vegetable should be combined with foods rich in vitamin C to increase absorption.
Cabbage
Cabbage contains about 105 mg of calcium per 100 grams. This vegetable is low in oxalates, making it easier for the body to absorb calcium. According to the Journal of Bone and Mineral Research, cabbage is also rich in antioxidants, which help protect bones from harmful agents.
Spinach
Spinach provides about 51 mg of calcium per 100 grams. In addition to calcium, this vegetable also contains magnesium and vitamin D - two important nutrients that help strengthen bones and teeth.
Asparagus
Asparagus is not only a good source of calcium, but it is also rich in vitamin K and folate. According to the British Journal of Nutrition, regular consumption of asparagus helps improve bone density and reduce the risk of arthritis.
Spinach
Amaranth contains about 215 mg of calcium per 100 grams, making it one of the richest vegetables in calcium. Amaranth is also rich in iron and vitamin C, which helps the body absorb calcium more effectively, according to research from the American Society for Nutrition.
