In its most comprehensive study yet on the healthy compounds, the
US Department of Agriculture suggests that certain varieties of fruits, nuts and veggies contain more antioxidants than others.
And flavonoid content varies widely between individual samples. For example, a market may display a tub full of red delicious apples, but flavonoid levels in each individual apple may vary, reports ABC online.

Nutritionist David Haytowitz, one of the study`s authors, says that taxing conditions, such as those created by more natural farming methods, appear to force plants to release greater amounts of flavonoids and other beneficial compounds.
"Insect attacks and weather conditions can be stressful to plants," he says. "Even harvest times are important, as early morning harvests are less stressful than those conducted around noon, since the midday sun adds to a plant`s stress."
