Given our friendly ongoing debate on the benefits of fruit, a few parts really stood out to me:
Morris' study also found that high consumption of fruit had no effect on thinking ability. A similar large-scale study, the Nurses' Health Study, also found that high vegetable consumption, but not high fruit consumption, was associated with a slower rate of cognitive decline.
One of the most common antioxidants found in fruit, vitamin C, has not been consistently shown to protect the brain, Morris said. Most of her study participants consumed fruit such as oranges, grapefruits, apples and bananas, which are high in vitamin C.
It's possible that some fruit may contain compounds that counteract antioxidants. Further studies are needed to determine whether fruit is brain-protective, she said.
As for eating vegetables, Morris said it's too soon to say for sure that they actually preserve the brain from age-related decline. "But it's encouraging to see that it appears to slow the rate of decline," she said. "We know that eating vegetables is important for chronic diseases. So this might be one more reason why you should eat your vegetables."
The authors also discuss how people's tendency to mix fats and veggies together may heighten the health benefit of the latter.
When average Joe or Jane eats fruit, it's usually as a stand-alone snack between meals. Maybe fruit, like veggies, has a greater positive impact on health when consumed alongside a fat source? Who knows! :-)
