Healthy diets with only 10% ultraprocessed foods may raise risk of cognitive decline, stroke

Eating an increased amount of ultraprocessed foods has been associated with a higher risk of cognitive decline and stroke. This risk remains even when following a plant-based diet like the Mediterranean, DASH, or MIND diets. Conversely, consuming more unprocessed or minimally processed foods is linked to a lower risk of cognitive impairment. Ultraprocessed foods, high in calories, sugar, and salt, and low in fiber, contribute to various health issues such as obesity and high blood pressure. A recent study examined data from 30,000 participants and found a higher risk of stroke and cognitive decline among those who consumed more ultraprocessed foods.
