Sugary drinks include beverages like soda, sports drinks, energy drinks, and fruit crush.
A high intake of sugary drinks not only expands your waistline and boosts your risk of type 2 diabetes and heart condition — but it also features a negative effect on your brain.
Excessive intake of sugary drinks increases the chances of developing type 2 diabetes, which has been shown to extend the danger of Alzheimer’s disease.
In addition, higher sugar levels within the blood can increase the danger of dementia, even in people without diabetes.
A primary component of the many sugary drinks is a high-fructose syrup (HFCS), which consists of 55% fructose and 45% glucose.
A high intake of fructose can cause obesity, high vital sign, high blood fats, diabetes, and arterial dysfunction. These aspects of metabolic syndrome may cause a rise within the long-term risk of developing dementia.
Animal studies have shown that prime fructose intake can cause insulin resistance within the brain, also as a discount in brain function, memory, learning and therefore the formation of brain neurons.
One study in rats found that a diet high in sugar increased brain inflammation and impaired memory. Additionally, rats that consumed a diet consisting of 11% HFCS were worse than those whose diets consisted of 11% regular sugar.
Another study found that rats fed a high-fructose diet gained more weight, had worse blood glucose control and a better risk of metabolic disorders and memory impairments.
While further studies in humans are needed, the results suggest that a high intake of fructose from sugary drinks may have additional negative effects on the brain, beyond the consequences of sugar.
Some alternatives to sugary drinks include water, unsweetened ice tea, vegetable juice, and unsweetened dairy products.
