The Claim

In postmenopausal Iranian women, higher adherence to an unhealthy plant-based diet is associated with significantly lower intake of whole grains, fruits, vegetables, legumes, nuts, dairy, and animal proteins, and higher intake of refined grains and sweets.

In plain English

Postmenopausal Iranian women who follow an unhealthy plant-based diet eat fewer whole grains, fruits, vegetables, legumes, nuts, dairy, and animal proteins, and more refined grains and sweets.

See the scientific wording

In postmenopausal Iranian women, higher adherence to an unhealthy plant-based diet is associated with significantly lower intake of whole grains, fruits, vegetables, legumes, nuts, dairy, and animal proteins, and higher intake of refined grains and sweets, suggesting a pattern of nutrient-poor plant food consumption.

Why this might work

Eating mostly refined grains and sweets instead of whole plants means the body gets less calcium, magnesium, and potassium. Without these nutrients, bones lose minerals and weaken. At the same time, these processed foods make the body more acidic, which causes the kidneys to flush out more calcium from the bones into the urine, making bones even weaker.

    Women who ate more sweets and white bread had much weaker bones, while those who ate more fruits, veggies, and whole grains had stronger bones — so the unhealthy plant-based diet really does mean eating worse, nutrient-poor foods.
