As I am reading the article, maybe it's not the vegetables, but the vitamin E:
""We had found in previous studies that vitamin E in food protected against cognitive decline and the development of Alzheimer's disease," she said.
Her previous research also had shown that consumption of healthy fats, such as the polyunsaturated and monounsaturated fats found in foods such as olive oil, were similarly protective.
"When we eat vegetables, we tend to put the good fats on them, such as an oil-based salad dressing on salads, healthy-fat mayonnaise on cole slaw, and healthy-fat margarine on vegetables," Morris said. "Such fats help us to absorb the vitamin E, and perhaps are also beneficial to the brain. So that's one plausible explanation of why vegetables are good for you."

This is NOT research, if they can't tell for sure whether the vegetables or the oils put on them were the ones that helped. How stupid!
But in general, both vitamin E and vegetables are good for you, but this "research", if you can call it that if not conclusive.
Clarification: my post 15 refers to the article I opsted in post 7 about green leafyvegetables.
The study about drinking reduces heart attack risk was well done.
