In the second episode of The Educated Kitchen, Eva Tolchinsky, M.S., RDN, a clinical and outpatient bariatric dietitian at Raritan Bay Medical Center and Old Bridge Medical Center in New Jersey, joins Chef Urvick Bouloute to make a vibrant watermelon salad with red, yellow and orange watermelon, strawberries, cucumber and feta cheese.
Fruit can fit into a diabetes-friendly diet
Tolchinsky said the recipe is “a great opportunity to debunk the myth that individuals with diabetes cannot have fruit.” Fruit does contain carbohydrates, so portion sizes matter, she explained, but it also provides fiber, vitamins, minerals and antioxidants.
The different colors of watermelon each have their own mix of carotenoids, plant pigments that act as antioxidants. Some carotenoids can be converted into vitamin A, which supports immune function. Strawberries add fiber from their seeds and are rich in vitamin C.
Nutrition in every ingredient
Cucumber, a nonstarchy vegetable, adds hydration and micronutrients. Feta cheese contributes calcium and protein, though Tolchinsky noted it contains sodium, so people watching their salt intake should be mindful of how much they use. Fresh mint and shallots boost the flavor along with adding nutrients.
Bouloute recommends cutting all the fruit and vegetables to the same size so every spoonful includes a bit of each ingredient.
A simple vinaigrette with heart health in mind
The dressing combines olive oil with fresh orange and lemon juice, citrus zest and cracked black pepper. Tolchinsky pointed out that cardiovascular disease is the leading cause of death in the United States, and that heart health is especially important for people with diabetes. Olive oil provides unsaturated fats, which can support heart health when used in place of saturated fats.
Using citrus for flavor also reduces the need for added salt or sugar, she said.
For the best flavor, Bouloute suggests letting the dressed salad rest for 20 to 30 minutes so the watermelon can absorb the mint, shallot and citrus.
