Diet Linked to Reduced Risk of Dementia for Millions
In a groundbreaking development, recent research suggests that reducing carbohydrate intake, particularly refined carbs and gluten-containing grains, could play a significant role in the potential prevention of Alzheimer's disease.
The low-carb diet, which eliminates energy-dense carbohydrates like bread, pasta, and rice but permits some vegetables, primarily leafy greens, has been associated with multiple mechanisms that may help protect against Alzheimer's.
One such mechanism is the reduction of inflammation. Gluten found in grains like wheat, barley, and rye can trigger intestinal inflammation, increasing permeability and allowing harmful proteins into the bloodstream. This prolonged inflammation can spread to the brain, contributing to Alzheimer's disease development. Removing gluten and reducing carbohydrate intake can mitigate this inflammatory pathway and thus potentially lower Alzheimer's risk.
Another link is the association between high intake of refined carbohydrates and insulin resistance. Insulin resistance interferes with neurons' ability to use glucose effectively, accelerating cognitive decline and promoting the accumulation of amyloid plaques - a hallmark of Alzheimer's disease. Reducing intake of processed and high-carb foods can improve insulin sensitivity and slow dementia progression.
Diets emphasising complex carbohydrates that increase insulin sensitivity, such as those in the MIND diet, appear beneficial. Processed and low-quality carbohydrates are linked to greater cognitive impairment, while higher-quality protein intake combined with reduced low-quality carb consumption may improve cognitive outcomes.
Overall, plant-based, anti-inflammatory diets rich in fibre, antioxidants, and low in processed carbs support brain health by reducing oxidative stress and inflammation, key factors in preventing Alzheimer's and related dementias.
While approximately six percent of British adults currently follow a low-carb or keto diet, the estimated number of Brits with Alzheimer's disease is around 900,000, and it's projected to rise to 1.7 million within two decades. This development offers a glimmer of hope, as studies link carbohydrate quality with cognition and Alzheimer's risk.
However, it's important to note that while the potential benefits of a low-carb diet in preventing Alzheimer's are promising, studies have also suggested that this diet could raise the risk of heart disease and other deadly cardiovascular conditions. As always, it's crucial to consult with a healthcare professional before making significant changes to one's diet.
In other related news, a study published in The Lancet has provided more hope than ever before that Alzheimer's can be tackled. World-leading experts found that high cholesterol and suffering vision loss were new risk factors for dementia, joining 12 existing factors identified as increasing the risk. In 2022, 74,261 people died from dementia in the UK, making it the country's biggest killer.
Memory problems, thinking and reasoning difficulties, and language problems are common early symptoms of Alzheimer's. Alzheimer's Disease is the most common form of dementia, affecting 982,000 people in the UK. The ongoing research into the potential benefits of a low-carb diet and other lifestyle factors in preventing Alzheimer's promises to continue shedding light on this complex and devastating condition.
- The low-carb diet, which eliminates energy-dense carbohydrates, could potentially lower the risk of Alzheimer's disease due to its association with reduced inflammation and improved insulin sensitivity.
- Removing gluten and reducing carbohydrate intake can mitigate the inflammatory pathway that contributes to Alzheimer's disease development.
- Reducing the intake of processed and high-carb foods can improve insulin sensitivity and slow dementia progression, as high intake of refined carbohydrates is linked to insulin resistance and cognitive decline.
- Diets rich in complex carbohydrates, such as those in the MIND diet, support brain health by reducing oxidative stress and inflammation, key factors in preventing Alzheimer's and related dementias.
