Group of foods worsening memory in women identified
Scientists from New York University found that frequent consumption of ultra-processed foods in middle-aged women is linked to poorer memory and cognitive functions later in life. The findings were published in the journal Preventive Medicine.
Ultra-processed foods include sweets, fast food, soda, ready meals, and more. These foods are high in added fats, sugar, salt, and artificial flavorings.
Data from over 5,000 women in the Women's Health Study showed that those who consumed the most ultra-processed foods between ages 35 and 65 were about 20–24% more likely to report cognitive complaints such as memory and concentration difficulties 25–35 years later.
These complaints were subjective experiences of declining memory or focus, which previous studies suggest may precede dementia by several years.
A particularly strong link was found with processed dairy and meat products, while no significant association was seen with sweets or sauces.
Women make up about two-thirds of Alzheimer's patients. Early identification of risk factors is a priority for healthcare. The researchers emphasized that reducing ultra-processed food intake could be a practical way to lower the risk of age-related cognitive decline.
