When it comes to bone health, milk is usually the first – and sometimes the only – protagonist. However, nutrition specialists agree that maintaining strong bones throughout life depends on a combination of nutrients that goes far beyond a glass of dairy: calcium, vitamin D, vitamin K, magnesium and protein work together to preserve bone density and reduce the risk of fractures and osteoporosis.
But it is worth noting that calcium does not live only in dairy products.
Calcium is the mineral most associated with bones, and with good reason: it is part of their structure. But there are plant and animal sources that are equally valuable:
Vitamin D, the great silent ally
There is little point in consuming calcium if the body cannot absorb it correctly, and that is where vitamin D comes into play. This vitamin facilitates the incorporation of calcium from the intestine into the bloodstream and, finally, into the bone.
The main source of vitamin D is sun exposure, but it can also be obtained from:
Vitamin K: the least known but essential nutrient
Vitamin K intervenes in the formation of a protein called osteocalcin, responsible for fixing calcium in the bone matrix. It is mainly found in:
Magnesium and potassium, the minerals that work as a team
Magnesium participates in the conversion of vitamin D to its active form and in bone mineralization. It is located at:
Protein: a structural component, not muscle
About half of bone volume is made up of protein, mainly collagen. Therefore, adequate protein consumption—present in lean meats, fish, eggs, legumes and dairy products—is as relevant as calcium when it comes to maintaining strong bones.
A varied diet, the best recipe
Experts insist that there is no single “miracle food” for bones: the key is variety. Combining green leafy vegetables, fish, legumes, nuts and moderate sun exposure allows you to meet the needs of calcium, vitamin D, vitamin K, magnesium and protein without depending exclusively on dairy products.
This variety is especially relevant for people with lactose intolerance, who follow vegan or vegetarian diets, or simply seek to diversify their diet without neglecting the health of their skeleton, a care that becomes especially important after the age of 30, when bone density begins to decrease naturally.
