Available year-round, zucchini is at its best during the summer season, especially if freshly plucked from your own garden. A delicious source of potassium, vitamin C, vitamin A, folate, and fiber, it packs a nutritious punch for a mere 27 calories per cup cooked. Registered dietitian Rachael Hartley says summer vegetables like zucchini, simply seasoned with olive oil, garlic, salt, and pepper, are delicious on the grill. “I like to make extra and use leftovers for pasta, salads, and sandwiches during the week,” says Hartley.
New York City-based nutritionist Natalie Rizzo, MS, RD says, “there’s nothing better than sweet summer corn. I like to throw it on an indoor grill in the husks. It gives a nice smoky charred flavor. To make it a little special, top with cotija cheese and a squeeze of lime.” A medium ear of corn offers about 3 grams of fiber, some protein, and potassium. Corn also contains the compounds lutein and zeaxanthin, which have been linked to reduced risk for macular degeneration according to a 2015 article in the Journal of Ophthalmology.
