Staying healthy is important year-round, but especially in the cooler months when temperatures drop, people spend more time inside and germs can spread easily. What you eat and the lifestyle you embrace are critical components of staying healthy.

Nourishing meals full of fruits, vegetables, protein-rich foods and whole grains help provide the body's immune system with the nutrients it needs. Maintaining a healthy lifestyle by getting enough sleep, being physically active every day, having enough fluids and reducing stress also help keep the immune system in shape.

As a nutritious food to include on your grocery list, grapes of all colors - red, green and black - contain more than 1,600 natural plant compounds such as antioxidants and other polyphenols that help protect the health of cells throughout the body. They also contain about 82% water, so they provide important fluids for hydration, which is also critical to a healthy immune system.

Grapes can be enjoyed as a healthy snack or an immune-boosting ingredient in recipes like Chicken, Spinach and Grape Pita sandwiches and Grape and Salmon Power Salad. Each provides a mix of immune-supporting nutrients, including zinc in chicken, vitamins A and C in kale, polyphenols in grapes and other important nutrients in the salmon, walnuts and barley.
