Dietitians Advise Limiting Candy to Mitigate Dementia Risk

In a comprehensive review of dietary impacts on cognitive health, nutrition experts have identified high added sugar consumption, particularly from candy, as a significant risk factor for dementia. This assertion emerges amid growing global concerns about dementia prevalence, which currently affects over 55 million individuals worldwide, with Alzheimer’s disease representing 60% to 70% of these cases. According to Lauren Manaker, M.S., RDN, LD, CLEC, a registered dietitian and nutrition expert, the consumption of candy and other high-sugar foods should be approached with caution to support brain health. This advice is supported by recent findings indicating that high levels of added sugars can lead to increased risks for Alzheimer’s disease and other dementias.

Recent research highlights a concerning correlation between high sugar intake and the development of amyloid plaques in the brain—characteristic of Alzheimer’s disease. "Candies are not your brain’s friend," states Maggie Moon, M.S., RD, emphasizing that diets consistently high in added sugar may significantly disrupt brain functions. A study highlighted by Moon found that each additional 10 grams of added sugar consumed daily correlates with a 1.3% to 1.4% increase in the risk of developing Alzheimer’s disease.

Furthermore, Laura M. Ali, M.S., RDN, reinforces this viewpoint, detailing that high blood sugar levels can lead to insulin resistance affecting brain regions critical for memory and cognition. The World Health Organization (WHO) and other health institutions recommend limiting added sugars to less than 10% of total daily caloric intake to mitigate various health risks, including cognitive decline.

In addition to curbing candy and sugary products, experts advocate for a holistic approach to brain health that includes regular physical activity, social engagement, and a balanced diet rich in antioxidants. Effective dietary patterns such as the Mediterranean-DASH Diet Intervention for Neurodegenerative Delay (MIND) diet emphasize the importance of consuming whole grains, nuts, berries, vegetables, and healthy fats while limiting saturated fats and sugars.

The implications of these findings are profound, as the world faces an escalating dementia crisis. According to a report by the Alzheimer’s Association, the number of people living with Alzheimer’s is projected to rise to 14 million by 2050 in the United States alone. As such, public health initiatives are increasingly focusing on preventive strategies that encompass diet and lifestyle modifications.

Experts urge individuals to adopt brain-healthy habits early in life. This includes moderating alcohol consumption, engaging in regular exercise, and managing chronic health issues effectively. Dr. Sarah Johnson, Professor of Neuroscience at Stanford University, notes that maintaining social connections and mental engagement can also bolster cognitive resilience as individuals age.

In conclusion, while no single food or lifestyle choice guarantees immunity from dementia, adopting a balanced diet low in added sugars, especially from candy, coupled with a healthy lifestyle, may significantly reduce the risk of cognitive decline. As research continues to evolve, health professionals stress the importance of making informed dietary choices as part of a broader strategy to promote long-term brain health.
