According to the Center for Disease Control and Prevention, nutrient dense foods are those that provide an average of 10% or more daily value per 100 calories of 17 nutrients, including potassium, protein, fiber, iron and calcium (DiNoia, 2014). While there are several fruits and vegetables that are nutrient dense, there are some in particular that are best in the summertime, because they also happen to be refreshing and help with hydration. Citrus fruits and berries are excellent choices for summer snacking. According to CDC’s nutrient density approach, the healthiest of them all is the strawberry, with a nutrient density score of 17.6 (DiNoia, 2014). According to the FDA, strawberries have more vitamin C than any citrus fruit, and are also rich in potassium and fiber. As an added bonus, strawberries are a good source of flavonoids (Odriozola-Serrano et al., 2008) group of phytonutrients linked to reduced risk of diabetes, heart disease, and some cancers (Arnoldi, 2004). Strawberries are about 92% water (NNDS, 2016) a proportion similar to that of watermelon; and, because of their electrolyte content, strawberries are an ideal source of hydration on warm days. If you aren’t a fan of eating a portion of plain fresh strawberries, the flavor of strawberries is delicious when sliced pieces are added to your ice water. There are also many healthy summer recipes, both sweet and savory, that contain strawberries, such as the Caprese Salad with Strawberries recipe below.
