1、 Definition and symptoms of osteoporosis
Osteoporosis
A systemic and systemic bone disease characterized by decreased bone mass and degeneration of bone tissue and fiber structure, resulting in increased bone fragility and fracture risk.
2 classification of osteoporosis
(1) primary osteoporosis
(2) secondary osteoporosis
(3) idiopathic osteoporosis
Symptoms of osteoporosis
(1) pain
(2) shortened body length and hunchback
(3) fracture
(4) decreased respiratory function
2、 Functional food for improving osteoporosis
1 protein
Protein is the main raw material for the synthesis of bone organic components. Without enough protein to supply bone synthesis, bone tissue cannot be formed. According to the actual situation of our country, the daily intake of protein for the elderly should be about 60-90g.
2 fat
If the long-term intake of lipid is insufficient, the risk of osteoporosis will increase due to the lack of vitamin D; however, if the intake of fat is too much, the bone will become loose and easy to break, so that people will suffer from osteoporosis.
3 vitamins
(1) vitamin D promotes the absorption of calcium and phosphorus, and promotes the growth and development of bones and teeth.
(2) vitamin A promotes the growth and development of bones and teeth.
(3) vitamin K can act on osteoblasts, promote calcification of osteoblasts, inhibit osteoclasts, cause ancient absorption, increase bone density, and prevent osteoporosis.
4 minerals
(1) calcium is the necessary material basis for normal development and growth of bone.
(2) zinc deficiency is related to osteoporosis density, which affects the proliferation of bone cells and the synthesis of collagen in bone matrix, and further plays an important role in the regulation of bone formation and calcification.
(3) phosphorus excess is one of the risk factors of osteoporosis.
