WATERLOO (KWWL) -- Eating less may help boost your memory late in life.
German researchers had a group of older, healthy adults cut their daily caloric intake by 30-percent. After three months, they did better on a memory test than a control group, who stuck with their regular diet. A third study group ate more unsaturated fatty acids, found in fish and olive oil. But, that didn't make any difference on the memory test results.
