Our best choice is to consume a variety of the types of plants available to us , ranging from garlic , leeks and onions containing allyl sulfides , to cruciferous vegetables containing indole-3-carbinols , to citrus fruits and berries containing effective antioxidants such as ellagic acid and ascorbic acid . Dr. Russel J. Reiter calls it Melatonin : Your Body 's Natural Wonder Drug , and presents his perspective , based on more than 30 years of melatonin research , on the drug 's potential , including its role as a powerful antioxidant and where to find it in the foods we eat . Similar patterns exist for most of the key antioxidant enzyme systems in brain and liver . The antioxidant , dubbed AEOL 10113 , mimics the naturally occurring antioxidant superoxide dismutase , but is effective against a wider range of antioxidants and lasts longer in the body . Or it could be that we isolated the wrong antioxidant . So , we do not believe that all such problems are inevitable and , with appropriate glucose control , A1c control , monitoring of these other risk factors and earlier interventions ( i.e. ACE inhibitors , statins , aspirin , antioxidants , not smoking , avoiding obesity ) , these types of risk factors can be overcome . The case of the antioxidants points up the dangers in taking a nutrient out of the context of food ; as Nestle suggests , scientists make a second , related error when they study the food out of the context of the diet . Preliminary results from a test conducted by Byrne and Dr. Luis Cisneros-Zevallos , Experiment Station food technologist , showed that peaches have good to excellent antioxidant activity , some antimicrobial activity , potential for use as a natural food colorant , and good to excellent tumor growth inhibition activity . One very small study reported benefits from a combination of the antioxidants alpha lipoic acid ( thioctic acid ) , silymarin ( found in milk thistle ) , and selenium . In cultured fetal rat hepatocytes , oxidant-related damage caused by ethanol exposure can be mitigated by augmenting / normalizing antioxidant defenses .
