New research indicates that a preference for specific foods may be associated with a longer lifespan, while liking certain other items could be linked to a higher risk of death. The study, which surveyed over 177,000 individuals across the United Kingdom, explored food preferences as a more stable indicator of dietary habits than recall of recent food intake.
Researchers asked participants about their favorite foods and then tracked their survival rates over more than three years. The findings highlighted six foods and ingredients associated with a lower risk of death and five linked to an increased risk.
Among the items associated with a higher risk of mortality, sugary soda showed the strongest link, with a 38% increased risk. Diet sodas followed, with a 23% higher risk. Sweetened tea was associated with a 22% increase in death risk, and whole milk with an 18% increase. Corn flakes were linked to a 20% higher risk, underscoring potential concerns about ultra-processed foods.
Interestingly, alcoholic beverages such as beer, wine, and spirits did not show an association with increased mortality risk in this study. The researchers noted that a small subset of participants died during the study period, and these deaths were from all causes, not necessarily linked to diet or metabolic diseases.
On the other hand, liking certain foods was associated with a significantly lower risk of death. Extra virgin olive oil was linked to a 33% lower risk, and black pepper to a 28% lower risk, suggesting that cooking at home with fresh ingredients might be beneficial.
Among the foods themselves, asparagus and broccoli showed the strongest association with longevity, each linked to a 31% lower risk of death. Butternut squash was associated with a 25% lower risk, and eggplant with a 21% lower risk. Other foods such as whole-wheat bread, spinach, salad, onions, mushrooms, lentils, beans, and bell peppers were also associated with a longer life.
These foods, often staples of the Mediterranean diet, are known for their benefits in weight management, brain health, and reducing the risk of metabolic diseases. The study suggests that a preference for these whole foods, fresh produce, and fiber-rich items may play a role in promoting longevity.
