Fresh Fruits and Vegetables Provide Important Nutrients
A Look at Foods That Help Prevent The Flu, Colds and Other Illnesses
It is important to understand that what you eat throughout the day affects your immune system, as do a number of other factors in your life, such as your level of stress and how much sleep you get every night. Certain vitamins are also very important immune system boosters, specifically Vitamins A, C, D and E. Many of the following foods contain these important vitamins.
- Fruits and vegetables provide essential vitamins and minerals that boost the immune system, such as vitamins C and E, beta-carotene, and zinc. Many people do not eat enough servings of fruits and vegetables in a day. Nutritionists recommend at least five servings per day. Eat well-rounded servings of fruits and vegetables to ensure you enjoy the full benefit, including, but not limited to: citrus fruits, berries, apples, red grapes, broccoli, leafy greens, kale, onions, peppers, spinach, sweet potatoes, Brussels sprouts and carrots.
- Drink orange juice and eat red bell peppers to increase vitamin C levels, which is a well-known vitamin that helps prevent and fight illnesses.
- Eat yellow and orange vegetables that contain beta-carotene, which the body converts into vitamin A. Vitamin A assists the body’s immune system by increasing production of T-cells, which are important illness fighters. It is known to help fight respiratory infections. To obtain Vitamin A, consider these yellow and orange vegetables: butternut squash, carrots, yellow peppers, yellow potatoes, pumpkin, yellow summer or winter squash, sweet corn, sweet potatoes, or yellow tomatoes.
- Yogurt is a good food to include in your regular diet to ensure that you obtain the probiotics that act as good microorganisms in your digestive tract. If yogurt is not your thing, consider adding probiotics to foods that you eat or drink probiotic containing Kefir, which is a drink derived from a mixture of milk and kefir grains. Medical research has found that having good microorganisms in your digestive tract improves the function of the body’s immune-system and bolsters its defenses against illnesses. To get your healthy gut bacteria, look for yogurt and kefir with "live and active cultures."
- Eat two servings of salmon per week. Salmon is a good source of vitamin omega-3 fatty acids (fish oil). Omega 3 contains abundant anti-oxidants that help the immune system repair damaged cells and prevent illnesses. The reason for the limit of two servings per week is that some fish can contain high amounts of toxins from the environment, such as mercury and lead, which are harmful substances to humans in large quantities.
- Eat Foods rich in zinc. A diet that includes foods that contain zinc will support the body's ability to make white blood cells, which are potent illness fighters in the immune system. If you become ill, zinc also may help reduce the length of the illness. To obtain zinc through diet, eat spinach, chickpeas, sesame seeds, lentils, beef, chicken, and lamb. Of course, red meats, such as beef should only be eaten in moderation, as they can cause health problems when consumed in large amounts.
- Add garlic, onions, ginger, and lots of spices (oregano, turmeric) to your meals because they provide a wide spectrum antimicrobial agents to the blood stream that fight illnesses.
- Eat almonds to obtain vitamin E, which is a powerful antioxidant that the body uses to fight illnesses.
- Use garlic when you cook meals. Garlic contains sulfur compounds that have strong antiviral properties that deactivate active viruses in the body, which helps prevent and treat illnesses.
- Use the spice known as ginger to spice up meals. Ginger has antioxidant properties that are beneficial to the immune system. It is also an anti-inflammatory agent, which helps prevent and alleviate illnesses associated with inflammation.
- Eat mushrooms to boost selenium levels in your bloodstream. Selenium helps white blood cells produce cytokines, which are a part of the immune system that clear up illnesses. Mushrooms also contain beta-glucan, an antimicrobial agent that helps the body prevent infections.
- When it comes to treating yourself and having some desert, consider eating dark chocolate, just do not overdo it or you will cancel out the health benefits. Dark chocolate has higher concentrations of cocoa than milk chocolate. Cocoa helps the body produce T-cells, which help the body avoid getting sick. It also is an antioxidant, which helps remove harmful free radicals from the body.
- Drink plenty of fluids, especially water, because proper hydration keeps the immune system running at peak capacity. A properly hydrated body provides the mechanism the blood stream needs to transport germ fighting cells throughout the body. Avoid caffeine and alcohol, since they act as dehydrates.
- Eat proteins with each meal. Proteins provide the energy that your immune and detoxification systems need to run at maximum efficiency.
Steaming Vegetables Is The Best Way To Cook Them
How To Cook Foods To Retain Nutrients
Eating a healthy diet goes beyond making good choices regarding what you eat. The way in which you prepare nutritious foods is very important to ensure that the foods retain their nutrients when you consume them. The most important thing to remember is to not overheat food in water. Beneficial nutrients and vitamins are broken down in food that is overheated in water. The best way to prepare fresh vegetables is to steam them, since steaming minimizes the amount of hot water contact and helps retain the nutrients and vitamins that your immune system needs.
Foods To Avoid Because They Suppress The Immune System
Avoid eating foods high in sugar and made of white flour, because sugar and processed white flour suppress your immune system for hours while your body processes them. Caffeine and alcohol can also act as an immune system depressants, since they cause the body to work on removing them from your system, which takes away resources from your immune system. It is a good idea to only use caffeine and alcohol in moderation to keep your immune system healthy. Fried foods that are high in saturated fat can also lessen the effectiveness of the immune system by promoting inflammation, and should be avoided.
Are You Getting Enough Vitamins Through Your Diet?
Vitamin D Is Very Important To Prevent The Flu, Colds and Other Illnesses
While there are many nutrients and vitamins that are helpful to the body’s immune system, a focus on foods that are high in Vitamin D is important during the cold dark winter months. The body does not produce any Vitamin D naturally during the winter, due to a lack of sunlight exposure. While being in close contact with others and spending a lot of time indoors spreads colds, flus, and other illnesses during the winter months, the marked increase in illnesses during the winter season cannot be only attributed to these factors. The missing factor appears to be the dramatic drop in Vitamin D that occurs in the human bloodstream during the months in which sun exposure is minimal and Vitamin D is not produced naturally.
A Word of Caution About Vitamins and Minerals Regarding Health Conditions
If you are pregnant or have a health condition, it is important to consult a licensed medical professional before making a substantial change in your diet that increases your intake of vitamins and minerals. In some circumstances, high levels of certain vitamins and minerals can be detrimental to your health. When in doubt, always consult a licensed medical professional that is qualified to provide medical advice regarding proper vitamin and mineral intake.
