Anti-Osteoporotic Factors in ALMONDS
Eating almonds has many health benefits, such as reducing oxidative damage, improving lipid profile and lowering cardiovascular disease risk. It has also been associated with increased bone mineral density, and recent evidence suggests that its regular inclusion in the diet (at least 4 servings/week) may be a protective factor in relation to the risk of developing osteoporosis in postmenopausal women.
Both osteoblasts (bone-forming cells) and osteoclasts (involved in bone resorption and degradation) have been studied in the laboratory to test the effects of different dietary factors on their formation and function.
A study, conducted in Canada, tested 14 healthy subjects for the effects of serum obtained 4 hours after ingestion of 3 snacks consisting of almonds, rice and potatoes respectively, all identical in terms of macronutrient content.
The participants avoided consumption of supplements or foods high in antioxidants, maintained the same level of physical exertion and recorded food diaries to keep track of what they ate.
Blood samples were collected
Blood samples were collected from the subjects on an empty stomach and after consumption of 60g almonds, along with 97g white bread. These measures aimed to limit the effects of other factors. On separate visits, the two other menus consisting of rice and boiled potatoes with Cheddar cheese and butter were also tested.
The changes could not be linked to the antioxidant content of almonds (osteoclast formation is stimulated by reaction to oxidation)
All three snacks were similar in this respect.
In other words
In other words, the combined effect of the various chemical compounds in almonds or the known metabolites of almonds is much more relevant than the effects of any single nutrients or factors.
The data is considered direct evidence to support the association between regular consumption of almonds and a reduced risk of developing osteoporosis.
In conclusion, the value of whole foods along with a varied diet, deserves the attention and effort of proper menu planning.
