Yes, an apple a day is a great idea, but that's not the only thing that'll keep the doctor away. To really ensure you get the nutrients your body requires, you'll need to incorporate a variety of nutrient-rich foods filled with vitamins C and E, antioxidants, beta-carotene, and bacteria-fighting properties. Look for fresh fruits and veggies that are in season and local, as much as possible.

An easy way to get the immune-boosters you need to stay healthy is to eat with your eyes. That means, go for color and diversity because each fruit and veggie has its own unique way of nourishing your internal organs. There's a reason you eat soup when you're sick: you can throw in a wide assortment of veggies to contribute to your cure. Also, the heat from the soup, especially if you add in a little spice, will make you sweat, which will help clear out your sinuses and help flush out the toxins in your body. Make sure to add a healthy amount of garlic to whatever you're cooking. Its active ingredient, allicin, is a natural antibiotic, which can help you fight off anything that ails you. It also contains high levels of manganese, calcium, vitamin B1, B6, and C, phosphorus, copper, potassium, selenium, and trypotophan.
