Researchers at the Harvard Medical School's Institute for the Study of Age Change have found that the risk of a fracture of the femoral neck is higher in people whose diets do not contain enough protein.
A fracture of the femoral neck is one of the most serious fractures, as bone healing can take 8-12 months.
In many cases of fracture there is a risk of problems with the blood supply to the head of the femur, which leads to the death of the bone cells that make it up - vascular necrosis of the head of the femur.
In necrosis of the bone tissue, the leg is permanently shortened, which leads to difficulty walking, deterioration of quality of life and even disability.
In adult patients, in whom the bones are more difficult to heal and the recovery process is slower, a number of complications can occur, such as pneumonia, urinary tract infections, bedsores. But the biggest risk is pulmonary thromboembolism, which is a life-threatening condition. Pulmonary embolism may occur with prolonged immobilization of the patient.
The authors of the study analyzed the results obtained by nearly 1,000 adult participants and found that in those whose diet contained a quarter less protein, bone density and strength were reduced and the risk of fractures was 50% higher.
In addition, muscle mass in the lower extremities was also reduced compared to volunteers who had a balanced diet.
According to Dr. Marian Hanan, head of research, stronger muscles in the lower limbs also reduce the risk of falls and fractures of the femur.
In general, researchers at Harvard Medical School recommend that older women eat at least 46 grams of protein a day and men at least 56.
The main sources of protein are foods of animal origin, such as meat, poultry, fish, eggs, milk and vegetables, as well as nuts, seeds, legumes and cereals.
