A quick meal, a cookie and a soda. This common combination, a daily habit for millions, could have silent but profound consequences for the body.
Recent research from Tulane University has linked high consumption of ultra-processed foods to lower bone mineral density and an increased risk of hip fracture. The findings shed light on the quality of the modern diet and its effects on one of the pillars of health: our bones.
The study, published in the British Journal of Nutrition, analyzed data from over 160,000 participants in the UK Biobank over a period of more than 12 years. Results showed that those who consumed the most ultra-processed foods – products industrially manufactured with high amounts of salt, sugar, and unhealthy fats – experienced a reduction in bone density in key areas like the upper femur and lumbar region.
The data is clear: for every 3.7 additional daily servings of ultra-processed foods, the risk of hip fracture increases by 10.5%. This increase is equivalent to adding a frozen dinner, a cookie, and a soft drink to one’s daily diet.
Widespread Consumption Pattern
Ultra-processed foods are now a significant part of the daily diet for many. According to data from 2023, the Centers for Disease Control and Prevention (CDC) reports that these products account for 55% of the daily calorie intake of young adults and adults in many countries.
Lu Qi, distinguished professor at HCA Regents and the Celia Scott Weatherhead School of Public Health and Tropical Medicine at Tulane University, explained: “We followed the study participants for over 12 years and found that high consumption of ultra-processed foods was associated with reduced mineral bone density in several areas, including key areas of the upper femur and lumbar region.”
This research is particularly important given the increasing prevalence of ultra-processed foods in modern diets and the potential impact on long-term bone health.
Increased Risks for Younger Adults and Those with Lower Weight
The negative impact of ultra-processed foods is more pronounced in certain groups. The link between consumption and bone density loss was more significant in individuals under 65 and those with a body mass index (BMI) below 18.5. A low BMI is already a risk factor for bone health, and combining it with a nutrient-poor diet can amplify the adverse effect.
According to Qi, “the association could be stronger among those under 65 due to more efficient digestive function, which absorbs more of the harmful ingredients present in ultra-processed foods.” He suggested that age and body composition influence the extent of potential damage.
A Global and Growing Trend
The proliferation of ultra-processed foods is driven by changes in eating habits and the global food industry. These products, including flavored yogurts, breakfast cereals, and frozen pizzas, are characterized by their convenience, low cost, and long shelf life.
The problem lies in their composition: they typically contain low levels of whole ingredients and a high caloric content, with additives that deviate from their natural state.
Previous studies have already indicated links between the consumption of ultra-processed foods and diseases such as diabetes, cardiovascular disease, and some types of cancer. Now, evidence regarding their effects on bone health adds to the growing list of concerns.
Research cited in the Tulane publication references a 2016 study that observed lower mineral bone content in babies born to mothers who lived near fast-food establishments. A 2024 investigation already linked high consumption of ultra-processed foods to a greater risk of osteoporosis.
Insights from Science
The Tulane team notes that the results are not surprising, given that “ultra-processed foods have been systematically associated with various nutritional disorders, and bone health depends on adequate nutrition,” according to Qi.
The research highlights how easily these products are found in supermarkets and the normalization of their daily consumption.
“Ultra-processed foods are readily available on any supermarket visit, and these findings raise concerns about how they may affect our bone health,” Qi warned.
The findings from Tulane University add to a growing body of research pointing to the risks of a diet dominated by industrialized products, not only on metabolism and the cardiovascular system but similarly on bone structure.
