With Alzheimer's disease affecting millions of people across the United States, extensive research is being done every day to find cures and preventive measures. However, many people aren't aware that there are some things they can do in everyday life that may be able to help prevent the onset of the disease.

For instance, believe it or not, drinking coffee daily is believed to help prevent early onset Alzheimer's disease. According to a recent study published in the Journal of Alzheimer's Disease, participants with higher blood caffeine levels avoided the onset of the disease.

"These intriguing results suggest that older adults with mild memory impairment who drink moderate levels of coffee - about three cups a day - will not convert to Alzheimer's disease, or at least will experience a substantial delay before converting to Alzheimer's," said Chuanhai Cao, lead author of the study and neuroscientist at the University of South Florida.

Another beverage, generally consumed late in the day, could also help prevent the disease. Several studies have found that reservatrol, found in red wine, may help prevent diabetes, heart disease, cancer and memory loss, according to data from the National Institute of Aging. Reservatrol is also found in the skins of red grapes, berries, tomatoes, peanuts and chocolate.

In addition to these two preventative measures, it is important to protect your hearing throughout life, according to the Better Hearing Institute. The group found hearing loss is linked to several chronic diseases, including Alzheimer's disease.

"Hearing loss if far more serious than people realize," said Sergei Kochkin, BHI's executive director. "When left unaddressed, hearing loss negatively affects virtually every aspect of an individual's life."

According to the Alzheimer's Association, more than five million Americans are affected by Alzheimer's, with nearly $200 billion in healthcare costs associated with the disease. Though a considerable amount of research is being conducted to prevent and treat the disease, these measures may be able to help prevent the onset of Alzheimer's for many people.
