Eat Less, Remember More

German researchers report that cutting calories can improve memory and brain function. The researchers speculate that consuming fewer calories helps reduce levels of inflammation, a known risk factor for cognitive decline. Study participants cut 30 percent of their daily calories, which is 750 calories (about five and a half cans of cola) if you are consuming 2,500 calories a day.

How Is Your Memory?

Some of the memory erosion that comes with aging can be slowed or even reversed. For example, when aging cells in the front part of your brain, known as the prefrontal cortex, shrink, it causes a loss of "executive function," skills that let you multitask and focus intently on what you are doing. But you can improve executive function through physical exercise, which increases the blood flow and the availability of oxygen and glucose to your brain cells.

To do this, you need at least 30 minutes of cardiovascular exercise, such as aerobics or fast walking, three times a week. Even if you have been sedentary for a while, your ability to focus can improve markedly within a few months of starting an exercise program

Improve Your Memory Quickly With These Nine Tips

Though you may not nitice it until you reach your mid-60's, your memory starts a gradual decline around the ripe old age of 25, according to University of Michigan psychologist Denise Park.

"Younger adults in their 20's and 30's notice no losses at all, even though they are declining at the same rate as people in their 60's and 70's, because they have more capital than they need," says Park in Scientific American.

Most of this mental decline is quite harmless, though it may lead you to have trouble recalling certain facts or make multitasking more difficult. The good news is that, like your muscles, your brain can be built up and strengthened at any age, and here are the top tips to do so.

1. Exercise
2. Meditate
3. Get a good night's sleep
4. Concentrate
5. Make sure you'r getting enough iron
6. Eat apples
7. Use your brain
8. Don't worry about it
9. Have a cocktail (in moderation)
