Calcium is not the only nutrient needed to make old bones. Several elements of the vegetable kingdom seem to play a significant role in the mineralization of our bones. Among them, the carotenoid pigments of colored Fruit and vegetables yellow,mortal gold, orange and red. Explanation.

Some preliminary studies conducted in humans suggest that carotenoids inhibit bone resorption (its gradual disappearance with age) and stimulate the proliferation and differentiation of osteoblasts, ie cells responsible for bone formation. Affected individuals ofOsteoporosis have, according to some studies, blood levels of carotenoids lower than those observed in healthy subjects. Furthermore, consumption of carotenoids and fruit and vegetables in general, has a positive effect on bone health.
Many carotenoidsAs LycopeneThe beta-carotene, Or beta-cryptoxanthin, have shown interesting effects by stimulating the synthesis and / or preventing bone resorption. However, epidemiological evidence on the effect of carotenoid intake on bone health are less numerous.

Carrot, tomato, peppers, salmon …

The main sources of carotenoids in the diet are Fruit and vegetables. Those with red, orange or yellow are those most likely to contain large amounts of carotenoids.
Some carotenoidsSuch as lutein, beta-carotene or theAstaxanthinAre also present in animal sources (liver, butter, salmon, egg yolks). These come from the concentration of carotenoids along the food chain.

The carrots are not cooked

U.S. researchers have assessed the relationship between intake carotenoids and bone mineral density (BMD) of the hip, spine and head of the radius for 4 years in 334 men and 540 women aged 75 on average.
They found, among women, an association between intake Lycopene and changes in BMD at the lumbar spine. Among men, the association was significant for the contributions carotenoids total, buy mortal gold,beta-carotene, lycopene and lutein + zeaxanthin for trochanter BMD (each of the two processes of the proximal femur).
These results therefore support the beneficial role of carotenoids in maintaining the BMD of Seniors. They supported the need, with age, of course, eat enough DairyBut also to maintain an adequate intake of fruits and vegetables, emphasizing the variety of colors.
