A USDA study done by scientist recently discovered that top foods with the disease-fighting compound of antioxidants were the acai berry, beans and artichokes.

It was also confirmed that already well-known high antioxidant foods such as cranberries and blueberries–the researchers also found that Russet potatoes, pecans and even cinnamon are all excellent–although lesser-known, sources of antioxidants. Antioxidants are thought to fight cancer, heart disease, and Alzheimer’s.

“The bottom line is the same–eat more fruits and veggies,” states Ronald L. Prior, Ph.D., a chemist and nutritionist with the USDA’s Arkansas Children’s Nutrition Center in Little Rock, Ark., and lead author of the study. “This study confirms that those foods are full of benefits, particularly those with higher levels of antioxidants. Nuts and spices are also good sources.”

The new study is more complete more accurate than previous USDA antioxidant data and includes more foods than the previous study as high tech equipment was used by the researchers. They analyzed antioxidant levels in over 100 different foods, including fruits and vegetables–the new study also includes data on spices and nuts for the first time.

Among the fruits, vegetables and nuts analyzed, each food was measured for antioxidant concentration as well as antioxidant capacity per serving size. Cranberries, blueberries, and blackberries ranked highest among the fruits studied. Beans, artichokes and Russet potatoes were tops among the vegetables–pecans, walnuts and hazelnuts ranked highest in the nut category.

Spices are normally consumed in tiny increments, yet many are high in antioxidants. In terms of antioxidant concentration, ground cloves, ground cinnamon and oregano were the highest among the spices studied.

The data should prove useful for those seeking to add more antioxidants in their diet. You must still use caution as the total antioxidant capacity of the foods does not necessarily reflect their potential health benefit, which depends on how they are absorbed and utilized in the body.

The government currently has no guidelines for how people should consume antioxidants as part of their daily diet–this is the same dilemma with vitamins and minerals. One big problem is the lack of continuity amongst researchers.

For the time being it is recommended that you eat a variety of fruits and vegetables that are high in antioxidants like cranberries and acai berries.
