You may have heard that this is a particularly tough flu season. Simple actions like choosing healthy foods can boost the immunity of yourself and your family to give all of you the best chance of fighting off flu and colds.
Your Immune System
Your immune system defends your body against disease by ridding your body of foreign invaders. Your immune system is not a constant, though. Your actions can boost or inhibit your immunity. If your body is already struggling because you are tired, for example, you will have more difficulty fighting off a cold.
The simplest way to boost your immunity this winter is to understand which foods provide your body with the nutrients it needs to function well.
Basic Immunity-building Pantry
Foods help your immune system through the vitamins, minerals, and micronutrients that help the system function. The most important immunity building vitamins are: Beta carotene (increases number of cells fighting infection), Vitamin C (increases white blood cells and antibodies), and Vitamin E (increases B-cells that destroy bacteria). Immunity building minerals are zinc (helps white blood cells reproduce quickly) and selenium (increases fighting cells). Don’t run out and buy a supplement pill, though. You can get all of these vitamins and minerals in food.
Stock your pantry with colorful fruits and vegetables. Carrots and sweet potatoes have beta carotene. Citrus has vitamin C. Blueberries, cranberries, pomegranate seeds, cherries, and other dark blue, purple, and red fruits are high in antioxidants, which reduce inflammation. Elderberries are particularly good for helping you fight colds and flu as an antiviral an antioxidant. Mushrooms have selenium and many other minerals an vitamins. Garlic is a great flu fighter with antioxidants and other immune-building properties.
Choose a variety of proteins. Beans, nuts, fish, and lean meats can all contribute toward your immune-boosting diet. Almonds provide vitamin E. Salmon is rich in omega-3 fatty acids. Sunflower seeds have selenium, as do many nuts, whole grains, and seeds.
Add herbs and spices to your foods. Medicinal herbs, like echinacea, goldenseal, and astragalus, are all immune boosters that fight viruses or increase the efficiency of white blood cells. You don’t want to add these to your foods, though. Culinary spices, like cayenne, oregano, and ginger, are also bacteria fighters. Use them fresh if you can, but use them in any form. Even black pepper can give you a little immune boost.
Every Day Foods
The range of immunity building foods is broad. It wouldn’t make any sense for me to tell you that only 5 or 10 or 50 of them are best for you because there is enough variety for you to choose your favorites. Still, I am going to suggest a few foods that will help you build immunity every day.
Smoothies. Start your morning with smoothies. Add dark fruits and vegetables, almond milk or yoghurt as a base, a few ice cubes to make it cool and reduce the intensity. That’s it! Just choose a colorful collection every morning.
Soup. With lunch, have a cup of soup every day. Chicken or vegetable broth both make a good base, but make sure you add garlic, perhaps ginger, lots of herbs and spices, and a few colorful vegetables.
Salad. With dinner every night, have leafy greens. Spinach and romaine lettuce are both very nutritious. Choose your dressing carefully. Better yet, make your own from olive oil, vinegar, and herbs. Each of these gives you a little boost. Maybe sometimes you have cooked kale with cider vinegar instead, but make sure you eat leafy greens every day.
Whole Grains. If you are going to eat cereal or bread, make them rich and nutty. The variety of grains, nuts, and seeds will help you over time.
Doesn’t that seem simple? It is. Boosting your immunity really isn’t difficult to understand or to do. These choices are easy to make every day, and the benefits build over time.
Keep in Mind
Avoid processed ingredients like white sugar and bleached wheat flour. Just avoiding those two will help you avoid many processed foods that have been drained of most nutritional value.
Get enough sleep. Yes, that isn’t a food, but rest is important enough to the healthy functioning of your immune system that you can undermine all of the good work you do with nutritious food by not getting enough sleep. Sleep for your health.
