The Claim

In Chinese adults aged 55–65, higher adherence to an unhealthy plant-based diet, characterized by increased intake of refined grains, sweets, and preserved plant foods, is associated with lower bone mineral density, with individuals in the highest quintile of intake showing over twice the odds of osteopenia and nearly three times the odds of osteoporosis compared to those in the lowest quintile.

In plain English

Chinese adults aged 55–65 who consume more refined grains, sweets, and preserved plant foods have lower bone mineral density and higher rates of osteopenia and osteoporosis than those who consume less of these foods.

See the scientific wording

In Chinese adults aged 55–65, higher adherence to an unhealthy plant-based diet, characterized by increased intake of refined grains, sweets, and preserved plant foods, is associated with lower bone mineral density, with individuals in the highest quintile of intake showing over twice the odds of osteopenia and nearly three times the odds of osteoporosis compared to those in the lowest quintile.

Why this might work

Eating too many refined grains, sweets, and preserved plant foods changes the levels of certain fats and amino acids in the blood. This reduces a key amino acid needed to activate bone-building cells and increases other fats that block minerals from being deposited into bone. As a result, bone formation slows down and bone density drops.

  1. Study: Unraveling the role of serum metabolites in the relationship between plant-based diets and bone health in community-dwelling older adults

    In older Chinese adults, eating lots of refined grains, sweets, and preserved foods is linked to weaker bones — those who ate the most had more than twice the risk of bone thinning and nearly three times the risk of osteoporosis. The study confirms this link directly.
