This fragrant herb takes center stage when added to any summer dish, but it flies under the radar when it comes to its impressive nutrition content. “If you have a garden full of basil, savor it for more than its flavor! Basil has antioxidant properties and provides almost 25 percent of the vitamin K a woman needs in a day,” says Marisa Moore, RDN, a dietitian in Atlanta, Georgia. Add to a salad or marinade, sprinkle over berries and ice cream, or muddle into a skinny summer cocktail. Check out the 20 superfoods that could help you lose weight.

Sweet, tangy, and packed with antioxidants, grapes are quickly racking up the science to back up their superfood status. They’re good sources of vitamin K, which helps blood clot and may contribute to strong bones, and a study in Experimental Gerontology found that consuming grapes twice a day for six months protected against metabolic decline in regions of the brain associated with early Alzheimer’s disease, plus enriched metabolic activity in areas of the brain related to memory and attention. “Snack on them fresh, frozen, or add to salads, salsas, or smoothies,” says Moore. California grapes are in season from May through January.
