  1. Our Immune System (and How to Eat the Foods That Support It)


    boost your immunity

    Living in a pandemic has many of us thinking about ways we can stay healthy. Luckily, our bodies have a built-in defense mechanism that works hard to keep viruses at bay and us living longer and healthier.

    All we have to do is support it by maintaining a healthy weight and eating a wholesome, nutrient-dense diet. Below is a detailed look at our immune system — and how to eat the foods that support it.
     

    What exactly does an immune system do?


    Your immune system is basically your front line of defense to the harmful things that enter your body, things that cause disease, illness, viruses and more. Think of the immune system as your body’s army, an intricate web of defense walls and soldiers that protect you from invaders. In more scientific terms, the immune system is a network of stages and pathways that combat against the harmful microbes that you encounter every single day.

    There are two kinds of immunity: innate and adaptive.

    Innate immunity includes barriers — defenses like skin, stomach acid, mucus, enzymes in sweat and tears and the cells that attack foreign invaders.

    Adaptive immunity is a system that learns from an invader, called an antigen, and creates antibodies to destroy it. This form of immunity then remembers those invaders so that it can quickly destroy them if they enter the body again.
     

    What impacts an immune system?


    Immune systems are tough cookies, and obviously critical to keeping us going strong day-in and day-out. But there are some things that can cause disruptions in the immune system.
     

    • Autoimmune disorders

    Genetics are what makes you YOU, and that’s great. Sometimes, however, genetics can cause hypersensitivity in the immune system, causing antibodies to attack healthy cells instead of antigens. Some examples are type 1 diabetes, lupus and rheumatoid arthritis.
     

    • Immunodeficiency disorders 

    This occurs when the body’s immune system is so weakened that it becomes extremely susceptible to illness. While these types of disorders are sometimes genetic, it’s more common for them to be acquired by diseases like AIDS or cancer.
     

    • Toxins

    Excessive drinking or smoking, and things like air pollution, can interrupt the body’s natural ability to fight off antigens.
     

    • Age

    Getting older means your internal systems have to work a bit harder to function properly. That means, without help, systems produce fewer antibodies.
     

    • Excess weight

    Carrying around excess weight has been tied to chronic inflammation. While inflammation is a natural part of the immune system’s process, chronic inflammation can wear down the immune system’s effectiveness.
     

    • Poor diet

    Like everything in life, the immune system needs proper fuel to function well. If it’s lacking certain nutrients, it will not work at peak performance. Conversely, eating certain nutrient-dense foods may improve immune function.
     

    • Other

    Mental stress and lack of sleep have also been tied to reduced immunity capabilities.
     

    How to Eat the Foods That Support Immunity


    Now that we’ve covered some of the things that can impact immunity, let’s focus on something we can do to improve it: eating a healthy, well-rounded diet. It can’t be stressed enough how important that is when it comes to fighting off viruses and maintaining overall well-being. Eating ultra-processed foods that lack nutrients can not only expand the waistline, but can also decrease the immune system’s effectiveness. That’s why you should be keeping an eye out for those nutrients that are tied with growth of immune cells.

    Below are some common foods that contain those nutrients, which include vitamin C, vitamin D, zinc, selenium, iron and protein. They’re the types of things you should definitely be adding to the shopping list or looking for in a meal delivery service.
     

    • Yogurt
    • Garlic
    • Onions
    • Leeks
    • Asparagus
    • Artichokes
    • Fruits
    • Beans
    • Whole grains
    • Ginger
    • Apple cider vinegar
