Reduced brain size and risk of developing dementia can be the result of drinking more than six cups of coffee a day, British certified dietitian and celebrity chef Serena Poon told Eat This, Not That!
“One study showed that heavy coffee consumption, more than six cups a day, was associated with a decrease in brain volume and an increased risk of dementia. If you’re monitoring your caffeine intake, be sure to count your tea and chocolate intake,” she said.
In a Jan. 11 feature on drinks that cause premature brain aging, Poon added that cognition and thinking are just as affected by water deficiency. Considering that the brain is made up of almost 70% water, keeping the body hydrated is one way to keep the body and mind in good condition.
“Researchers have found that even mild dehydration can affect cognitive function. Keep in mind that drinks containing alcohol and caffeine are diuretics and can decrease overall hydration,” she said.
Serena Pun’s Russian colleague, nutritionist Mikhail Ginzburg, told on January 15 what you can eat before going to bed in order to be alert and sleepy in the morning. He emphasized that going to bed hungry is not worth it – this will cause a desire to eat too much during breakfast.
