Ultra-Processed Foods Linked to Higher Risk of Cognitive Decline and Stroke: Study Finds

Boston, Massachusetts United States of America
American Cancer Society recommends consuming 'very little' to no processed meat due to association with increased risk of colorectal cancer and all-cause mortality.
Examples include prepackaged soups, sauces, frozen pizza, ready-to-eat meals and pleasure foods such as hot dogs, sausages, French fries, sodas, store-bought cookies, cakes and candies.
Exchanging one or two meals a week of ultra-processed food for unprocessed or minimally processed alternatives resulted in measurable reduction in risk of stroke or cognitive impairment.
Greater intake of ultra-processed foods tied to increased risk of cognitive impairment by 12% and incident stroke by 8% for all participants.
Risk of stroke was even higher at 15% for Black participants.
Ultra-processed foods are typically high in calories, added sugar and salt but low in fiber.
Ultra-processed foods linked to higher risk of cognitive decline and stroke in study involving over 30,000 participants.
Ultra-Processed Foods Linked to Higher Risk of Cognitive Decline and Stroke: Study Finds

Ultra-processed foods, such as frozen waffles, yogurt, cereal, and ready meals, have been linked to a higher risk of cognitive decline and stroke in a study involving over 30,000 participants. The research published in the Neurology medical journal found that a greater intake of ultra-processed foods was tied to an increased risk of cognitive impairment by 12%, and incident stroke by 8% for all participants. For Black participants, the risk of stroke was even higher at 15%. However, exchanging one or two meals a week of ultra-processed food for unprocessed or minimally processed alternatives like fruits, vegetables, nuts and legumes resulted in a measurable reduction in the risk of stroke or cognitive impairment. Ultra-processed foods are typically high in calories, added sugar and salt but low in fiber. Examples include prepackaged soups, sauces, frozen pizza, ready-to-eat meals and pleasure foods such as hot dogs, sausages, French fries, sodas, store-bought cookies, cakes and candies. The American Cancer Society recommends consuming 'very little' to no processed meat due to its association with an increased risk of colorectal cancer and all-cause mortality. Some commercially available whole grain breads are considered ultra-processed but are healthier options compared to refined grains, as they contain fiber, magnesium, selenium and are linked to a lower risk of developing type 2 diabetes. Breakfast cereals with added sugars, dyes and additives fall into the ultra-processed food category. Look for breakfast cereals with no more than 6 grams of sugar per dry ounce or opt for store-bought granola bars that contain nuts and have the least amount of added sugar.

  • Deception (50%)
    The article makes editorializing statements and uses emotional manipulation by implying that consuming ultra-processed foods is dangerous and will lead to negative health outcomes. The author also engages in selective reporting by only mentioning the negative aspects of certain ultra-processed foods while ignoring their potential benefits.

  • Deception (5%)
    The author makes editorializing statements and uses sensational language in the title and throughout the article. The title implies that eating ultraprocessed foods raises the risk of cognitive decline and stroke 'even if a person is trying to adhere to a Mediterranean diet, DASH diet or the MIND diet.' However, according to Dr. Andrew Freeman, who was not involved in the study, 'this study can only show an association, not a direct cause and effect.' The author also uses emotional manipulation by stating that 'Studies on the dangers of eating ultraprocessed foods are piling up' and quoting Dr. W. Taylor Kimberly saying that 'the impact on blood vessels that leads to stroke and cognitive decline may also be due to the presence of additives including emulsifiers, colorants, sweeteners, and nitrates/nitrites.' The author selectively reports details from the study by focusing only on the negative aspects of ultraprocessed foods without mentioning that eating more unprocessed or minimally processed foods was linked with a 12% lower risk of cognitive impairment.
