The numbers add up for eating your five-a-day of fruits and vegetables

Coming out of COVID

As Americans begin to slowly move out of the COVID-19 pandemic, they may face old and new challenges. People should use this transition period to prepare mentally and emotionally for a post-COVID world. Steps include planning how to safely return to social gathering, restarting health habits that have fallen away, and addressing mental health issues.

Facts about fiber

Fiber improves digestion and may help lower a person’s risk for heart disease, diabetes, and cancer. But according to the 2020–2025 Dietary Guidelines for Americans, most people meet only half their daily fiber needs. The main reason is not following a basic healthy diet with foods high in fiber.

Expand your healthy cooking oil choices

The healthiest fats for cooking and using on food come from plants. Plant oils consist mostly of unsaturated fat, which in limited amounts is good for the heart. One can enjoy a wide variety of plant oils, such as avocado, canola, corn, flaxseed, grapeseed, olive, peanut, rice bran, safflower, soybean, sunflower, and walnut oils. But high heat can break down plant oil molecules and reduce health benefits. The most fragile plant oils include extra-virgin olive oil and nut oils, such as walnut oil.
