A team of experts found in a new study that people who reported consuming less caffeine had a higher risk of memory loss consistent with Alzheimer’s disease or mild cognitive impairment. They also had less amyloid protein, which is often linked to the development of Alzheimer’s disease.
The new study used data from 263 people with mild cognitive impairment or Alzheimer’s disease between 2010 and 2015.
The low caffeine intake group included those who consumed 216 mg or less of the substance per day. People who consumed more than 216 mg of caffeine per day were classified as having high caffeine intake.
A cup of coffee contains 113 to 247 mg of caffeine, and a 355 ml can of energy drink contains 41 to 246 mg of this substance.
After controlling for age, gender, smoking status and other factors, the researchers found that those who drank fewer caffeinated beverages had a higher risk of memory loss. Experts also noticed a link between caffeine consumption and amyloid protein levels. People who drank less caffeine had lower levels of plasma amyloid-β 42 (Aβ42) and abnormal rates of other types of amyloid proteins. It is known that low amounts of Aβ42 in the cerebrospinal fluid are associated with Alzheimer’s disease.
