As temperatures rise and fruit season gets underway, U.S. nutrition experts singled out the peach as the summer fruit that best combines flavor, freshness and health benefits. Dietitian Samantha Peterson, speaking to Martha Stewart’s website, said peaches are at their peak in summer, when they are at their best for both taste and nutrition. She said in-season peaches contain more water, are sweeter and juicier, and are often richer in antioxidants.
A major advantage is hydration. Peaches are about 89% water, making them especially useful for maintaining fluid balance in hot weather. They also provide potassium, magnesium and calcium, minerals that help regulate fluids, support muscle function and maintain a normal heart rhythm.
The fruit is also rich in antioxidants, including vitamin C, polyphenols and carotenoids such as beta-carotene, which gives peaches their orange-yellow color. These compounds help fight oxidative stress, a process linked to chronic diseases including heart disease, diabetes and some cancers. Researchers also say peaches may support heart health because potassium helps balance blood pressure and reduce sodium’s effects, while fiber and polyphenols may lower cholesterol and inflammation.
Peaches can also help the immune system, since they contain vitamin C, vitamin A and zinc. Vitamin C supports white blood cell production, and vitamin A is important for immune cell development. Beta-carotene is converted in the body to vitamin A, which is essential for the retina and low-light vision and helps protect eye tissue over time. A medium peach has about 2.2 grams of fiber, mostly insoluble, which aids digestion and prevents constipation, while soluble fiber supports gut bacteria and may help stabilize blood sugar. The article notes that people with peach allergies, those on low-potassium diets because of advanced kidney disease, and some people with IBS or FODMAP sensitivity should be cautious.
