Gut Health Impacts Your Immune System
You are what you eat! Did you know that 70 percent of your immune system is in your gut? (1) Research shows that our gastrointestinal system affects everything from our energy levels and immunity to our brain function. Yet sadly, stomach issues are highly prevalent across the US. Supporting your immune system is more important now than ever as we continue to be impacted by the pandemic.
According to a 2019 study, digestive diseases account for over 100 million ambulatory care visits annually. Whether it's bloating, acid reflux, constipation, gas, or diarrhea, Americans are suffering the effects of poor gut health. (2)
Tips to Boost Your Gut Health and Immune System
What can you do to support your immune system and incorporate healthy gut habits into your nutrition and lifestyle routine? Consider the following five tips:
1. Include pre-and probiotics in your diet
When you're struggling with poor gut health, sometimes you need to fight off the harmful bacteria in your GI system and create an environment that promotes good bacteria growth. Therefore, avoiding the foods that harm your gut is critical. You want your microbiome—everything in your gastrointestinal tract—to thrive! (3)
Adding pre-and probiotic-rich foods to your diet, which aid digestion, is one step you can take to help support your gastrointestinal system. Prebiotics are fiber-rich foods that stimulate the growth of good gut bacteria. Examples of foods rich in prebiotics include Jerusalem artichokes, garlic, asparagus, cabbage, onions, boiled potatoes, bananas, apples, grapefruit, walnuts, oats and chia seeds. (4)
Probiotic foods (or microbes) support the good bacteria (live microorganisms) and/or yeasts that live in your body naturally. Their job is to fight off harmful bacteria and include fermented foods like yogurt, cottage cheese, kombucha, sauerkraut, kimchi, pickles, and sourdough bread. Pairing these with your prebiotic foods works together to build a balanced gastrointestinal system. (5,6)
2. Eat high-fiber foods
The food you put in your body plays a significant role in your digestive tract function and how you feel. For instance, having the right amount of fiber in your diet can potentially normalize your bowel movements, lower your cholesterol levels, and even control your blood sugar. (7)
So how much fiber does your body need? The Mayo Clinic recommends 21 to 25 grams of fiber a day for women and 30 to 38 grams a day for men. (8)
Examples of foods high in fiber include:
Whole-wheat spaghetti
Oatmeal
Quinoa
Raspberries
Pears
Apples
Boiled green peas
Broccoli
Turnip greens
3. Keep your body moving
Just like nutrition, exercise is vital to your overall health and is a great immune booster. Research shows that regular aerobic exercise can benefit your gut microbiota (the microflora of the gut) and lead to several human health benefits like lymphatic and cardiovascular system improvement. For most adults, the Department of Health and Human Services recommends at least 30 minutes of moderate physical activity every day. (9, 10, 11)
Whether you walk, run, jump on a trampoline, or practice yoga or Pilates for 30 minutes each day, routine physical activity is a great way to keep your lymphatic system healthy. It helps balance the fluid in your lymph nodes, cut your stress, and improves your body's blood flow. Additionally, when you decrease your sitting time and actively move your body, you can lower your blood pressure and body weight. (12)
4. Limit your sugar intake
Sugar is a sneaky ingredient that companies love to add to their food and beverage products without customers even realizing it. Why? Because there are over 50 alternative names for sugar, including: (13)
Galactose
Dextrose
Corn syrup
Ethyl maltol
Galactose
Agave nectar
Fruit juice concentrate
Maltodextrin
Barley malt
High fructose corn syrup
You must pay attention to food labels because you never know how many of these alternatives will pop up in a single food or drink item. Consuming a high-sugar diet puts you at a greater risk for heart disease, diabetes, weight gain, high blood pressure and chronic inflammation. Additionally, sugar loves the harmful bacteria in your gut, and it slows your body's good bacteria production. (14) If you want your body to thrive, cut out the sugar!
5. Drink more water
Keeping your body well hydrated is essential to your overall health, especially when your body is 60% water. Not only does water regulate your internal body temperature, but it also metabolizes and transports carbs and proteins in your bloodstream and flushes out your waste through urination. (15) We need water to survive!
Depending on your body size, drinking at least six glasses of water every day is the general recommendation to stay hydrated.16 When you're dehydrated, your lymphatic system slows down, and you feel weak. (9) Not drinking enough water can also cause constipation. So increasing your water intake is even more essential when you're adding more significant amounts of fiber to your diet. The goal is to create an environment that promotes healthy bowel patterns, not constipation, gas or bloating.
