A recent study has found that consuming ultra-processed foods such as chips, soda, and hotdogs may increase the risk of stroke and cognitive impairment. The research followed over 30,000 participants aged 45 or older for an average of 11 years, with 14,175 studied for cognitive decline and 20,243 for stroke. Participants who ate more ultra-processed foods had a 16% greater risk of developing cognitive impairment and an 8% higher risk of stroke. In contrast, those who consumed more unprocessed and whole foods had a lower risk of both cognitive decline and stroke.
The study revealed that 768 participants were diagnosed with cognitive impairment and 1,108 had a stroke during the study period. Interestingly, Black participants faced the highest risk, as those who consumed high amounts of ultra-processed foods had a 15% increased risk of stroke. This adds to a growing body of research linking ultra-processed foods to various health conditions, including diabetes, depression, and death. Ultra-processed foods are made from extracted substances like fats, sugars, and starches, and undergo multiple processes. Examples include soda, chips, candy, hotdogs, and canned soup.
In the United States, ultra-processed foods make up the majority of the average American’s diet, contributing to almost 58% of their total calories. These foods also account for nearly 90% of the energy Americans obtain from added sugars. Processed foods, on the other hand, are not as harmful, as they have been altered but are still safe for human consumption. Unprocessed foods, such as fruits, vegetables, meat, and whole grains, contain minimal added ingredients. Given the negative impact of ultra-processed foods on health, experts recommend avoiding them and opting for whole foods instead.
Previous research has linked ultra-processed foods to a range of health conditions, including weight gain, diabetes, depression, and even an increased risk of mortality. Participants in one study who consumed a high amount of ultra-processed foods consumed around 500 extra calories daily and gained an average of two pounds over a short period. Women who consumed nine servings of ultra-processed foods daily were found to have a 50% increased risk of developing depression. Additionally, individuals who ate higher amounts of ultra-processed foods had a 4% higher risk of all-cause mortality.
To steer clear of ultra-processed foods, experts recommend shopping on the outer perimeter of grocery stores, where fresh and unprocessed items are typically located. This approach helps individuals prioritize whole and healthy foods over processed and unhealthy options. With the latest study highlighting the increased risk of stroke and cognitive impairment associated with ultra-processed foods, it is crucial for individuals to make informed choices about their dietary habits to protect their overall health and well-being.
