Age is a major risk factor – osteoporosis is common in advanced age when the supply of all nutrients often becomes limited and one-sided – insufficiently varied diet.

Underweight in youth (BMI 18.5) – mental anorexia and long-term psychiatric disorders.

Alcohol – excessive consumption has a negative impact on bone.

Weight reduction diets causing underweight, primarily in young individuals, have a negative impact on BMD (bone mass). Strict diets result in imbalanced and one-sided supply of nutrients. Low body weight may result in inadequate loading of bone, which is the main stimulus for its regeneration.

Acidifying effect on internal environment is associated, for instance, with consumption of sugar-sweetened soft drinks (coca-cola, etc.), excessive intake of proteins, salt and caffeine – more than five cups of coffee daily (with excessive amount of sugar).
