Well, three apples actually - or, two 8oz glasses of apple juice. Those are the equivalent amounts that humans would need to consume to match the amounts given to laboratory animals in a study that seems to indicate that consuming apples can improve memory.

Antioxidants in apples may help slow the decline of the neurotransmitter, acetylcholine, in the brain. Studies have shown that increasing the amount of acetylcholine in the brain can slow the mental decline of people suffering from Alzheimer’s.

Previous studies have shown that foods rich in antioxidants can slow brain-aging and boost memory.

Scientists believe boosting levels of an enzyme, Uch-L1, could help Alzheimer’s patients to restore memory. Brains affected by Alzheimer’s tend to be low in Uch-L1.

Scientists studied mice who had been given a shot to block Uch-L1 and found they were less likely to respond to training and learn. They also found that within three weeks after injecting mice who had brain plaque with the enzyme Uch-L1, they began to learn at the rate of healthy mice.

The enzyme has potential as a treatment in Alzheimers but needs much more study before it’s ready for human testing, the researchers said.

Enzyme May Help Memory in Alzheimer’s

Boosting health, energy and memory as we age are key elements to enjoying a happy and satisfying life. It isn’t surprising that what keeps the body healthy, also keeps the mind active and boosts memory retention.

Friends

Social interaction has been found to greatly increase mood and outlook. One great way to increase social contacts is through volunteerism. Check into programs that can utilize your talents and interests. How about programs at the local library reading aloud to children? Inquire at your local senior center about activities that match your interest and make new friends.

Exercise

Aerobic exercise, such as walking, increases circulation and therefore, the oxygen supply to the brain. In studies, exercise improved short-term memory and the ability to focus.

Diet

Maintaining a healthy diet rich in antioxidants, B vitamins and omega 3 fatty acids is not only good for your heart but also for your brain.

In short, Friends, Exercise and Diet are the keys to keeping your body and brain FED. Oh yeah, in case you hadn’t guessed it, mnemonic games such as making up acronyms to stand for important information is another way to keep your mind and memory sharp.
