Easy to snack on, mix into sparkling water or champagne, ideal for salads and desserts alike, there's a reason why strawberries are the star of the summer season. McMordie credits their high water content—92 percent, to be exact—as one of the many reasons they're superstars for our skin. One cup of these red beauties gives you 100 percent of the vitamin C your body requires in a day, helping to fight against free radicals—and preserve your youth. "Vitamin C is also important for the synthesis of collagen, one of the main components responsible for skin elasticity," she adds.

Often times when you break out, it's because of some sort of inflammation showing its impact in the form of aging symptoms or acne. To the rescue is this fatty fish that's high in omega-3, which helps to keep your skin calm and nourished. If you're not a fan of salmon, add some walnuts to your snacking routine, as they're also filled with this nutrient, McMordie says.

Lounging around on a lake on a float, reading a book and passing time, the only thing missing is an easy snack. Consider sunflower seeds for your vacation, since McMordie says they provide 37 percent of the daily value of vitamin E in one serving. "It's thought that vitamin E helps to boost immune function, which helps clear skin of acne," she explains. You can also nibble on peanuts, wheat germ and almonds for similar benefits.

With everything vibrant in color and growing steadily, the summer is ideal for gardeners—and those who love their creations. Pick, collect or buy leafy greens to make salads, side dishes and more, since McMordie says this vegetable type is naturally high in the antioxidants lutein and zeaxanthin, which help scavenge damage-causing free radicals. As a bonus, they also contain excellent amounts of vitamins C and A, which McMordie notes are vital for skin health.

Though you should love the skin you're in—most folks tend to eat lighter during the summer, since warm weather requires less clothing. This is good news for your skin, since lean meats of beef and pork and oysters are all great sources of minerals like iron and zinc. Ayoob explains the powerful perks of these ingredients: "Iron from animal sources is far better absorbed and utilized by the body than plant sources of iron. Lean cuts will have more of these important minerals, but less fat and calories, also."
