If you’re a woman who regularly reaches for coffee throughout the day, you may want to think twice about that next cup — or consider switching to tea.

Researchers at Flinders University reported in a study published in the journal Nutrients that high coffee consumption may be associated with lower bone mineral density (BMD) in older, postmenopausal women.

consumption → report → women
The scientists analyzed coffee and tea consumption among 9,704 women age 65 and older over a 10-year period.

During that time, they also measured participants’ BMD at the femoral neck and hip, areas where osteoporosis-related fractures commonly occur.

fractures → measure → neck
The researchers found that drinking tea was associated with higher total hip BMD, while drinking more than five cups of coffee per day was associated with lower BMD.

drinking → find → BMD
Moderate coffee consumption — about two to three cups a day — was not associated with negative effects on bone health.

The study also identified differences based on other health and lifestyle factors.

Coffee consumption was associated with lower femoral neck BMD among women with higher alcohol intake, while the positive association between tea and bone density was more pronounced among women with obesity.

The researchers wrote that osteoporosis, which is characterized by low BMD, “is a major global public health concern affecting individuals across all ages, genders and ethnicities.”

About one in three women and one in five men age 50 and older worldwide experience osteoporosis-related fractures, according to the study.

Women face a particularly high risk because they generally have lower bone mass and experience accelerated bone loss after menopause.

In the US, the number of adults age 50 and older with low BMD in the hip or spine is projected to increase by 17.2 million by 2030, adding to the healthcare costs and long-term disability associated with osteoporosis-related fractures, the researchers noted.

The scientists wrote that they studied the relationship between coffee and tea and bone health because dietary factors play a “crucial role in the prevention of noncommunicable disease and may influence bone health,” and these are two of the most widely consumed beverages globally.

Study co-author Ryan Liu told ScienceDaily “compounds called catechins, abundant in tea, may promote bone formation and slow bone breakdown.”

“Coffee’s caffeine content, by contrast, has been shown in laboratory studies to interfere with calcium absorption and bone metabolism, though these effects are small and can be offset by adding milk,” Liu said.

“Our results don’t mean you need to give up coffee or start drinking tea by the gallon,” Liu added.

“But they do suggest that moderate tea consumption could be one simple way to support bone health and that very high coffee intake might not be ideal, especially for women who drink alcohol.”
“This study offers an interesting look at how everyday beverages might relate to bone health, but the findings should be interpreted with caution,” Lisa Young, registered dietitian and adjunct professor of nutrition at New York University, told Fox News Digital.
“Because it followed women over time without assigning them to drink coffee or tea, it can only show associations, not prove that coffee weakens bones or that tea strengthens them.”
The study had limitations, including differences in participants’ lifestyles, its focus on bone density rather than fractures and relatively small effects seen mainly in older women, Young noted.

Symptoms of osteoporosis and early bone loss include back pain, loss of height over time and stooped posture, according to the Mayo Clinic.

“The bottom line for the public is reassuring: Moderate coffee intake appears fine, and there is no need to switch drinks for the sake of your bones,” Young said.

“The most proven ways to protect bone health remain getting enough calcium and vitamin D, staying physically active and avoiding smoking and excess alcohol,” she added.

“With that said, I do make a case for moderate amounts of coffee for good health.
