The Claim

In postmenopausal Iranian women, higher adherence to a healthy plant-based diet, characterized by increased intake of fruits, vegetables, whole grains, legumes, and tea/coffee, is associated with a 66-70% lower odds of low bone mineral density in the femoral neck and a 64-66% lower odds of low bone mineral density in the lumbar spine, after adjusting for age, BMI, physical activity, education, and calcium supplement use.

Support is ahead, but a single strong opposing study can change this.

In plain English

Postmenopausal Iranian women who eat more fruits, vegetables, whole grains, legumes, tea, and coffee have lower rates of low bone density in the hip and lower spine compared to those who eat less of these foods, even when accounting for age, body weight, activity level, education, and calcium supplement use.

See the scientific wording

In postmenopausal Iranian women, higher adherence to a healthy plant-based diet, characterized by increased intake of fruits, vegetables, whole grains, legumes, and tea/coffee, is associated with a 66-70% lower odds of low bone mineral density in the femoral neck and a 64-66% lower odds in the lumbar spine, independent of age, BMI, physical activity, education, and calcium supplement use.

Why this might work

Eating more fruits, vegetables, whole grains, legumes, and tea or coffee lowers the body's acid levels, which stops the kidneys from flushing out too much calcium. This extra calcium stays in the blood and gets used to build stronger bones in the hips and spine.

  1. Study: Healthy plant-based diet index as a determinant of bone mineral density in osteoporotic postmenopausal women: A case-control study

    Postmenopausal women in Iran who ate more fruits, vegetables, whole grains, and tea/coffee were much less likely to have weak bones in their hips and spine, even when accounting for age, weight, and supplements. Those who ate more sugary foods and white bread had much higher risks.
