Immune Health During the Colder Seasons

This time of year is filled with sneezing and sniffling. Unhealthier eating habits during the winter months may increase our chances of catching cold/flu symptoms. Nutrition plays a big role in our immune health, so it is important to keep the well balanced meals coming year round. I am not saying to ditch the sweets/desserts this holiday season but rather to make sure you are getting enough nutrients from food on a daily basis. Below are some of my top favorite nutrients to help fight off the cold and flu.

Protein: Consume a variety of protein sources such as seafood, lean meat and poultry, eggs, beans, peas, soy products, and nuts. Our body uses protein as a defense mechanism. Proteins help build and repair tissues as well create hormones and enzymes that support a healthy immune system.

Vitamin A: This is an important vitamin for our immune system as it helps keep our skin and tissues healthy to protect us from infections. Vitamin A is found in a variety of foods including sweet potatoes, kale, spinach, eggs, carrots, red bell peppers and fortified foods, such as cereal.

Vitamin C: No need to pop a daily vitamin C if you are consuming enough vitamin C containing foods. Eat a variety of fruits and vegetables, including red bell pepper, citrus fruits, tomatoes, and fortified foods. Vitamin C supports both the innate and adaptive immune system, and research shows that a deficiency in this nutrient impairs immunity and increases risk of infections.

Vitamin D: During the summer months – we are able to ensure adequate vitamin D from exposure to the sun. Unfortunately, many of us spend less time outdoors during the cold months, so we have to attain vitamin D from foods and/or supplementation. Some good sources include dairy products, oily fish (such as salmon and tuna), mushrooms, tofu, eggs, and fortified foods.

Pre and Probiotics: Ensuring that our guts stay healthy is important for not only our immune health but also our brain health. Build a stronger immune system by adding natural probiotics into your diet, such as yogurts, cheese, kombucha, kefir, and sauerkraut.
