Healthy Leaky Gut Syndrome Diet Plan
The human gut has a large area of intestinal lining, over 4,000 square feet of surface area, to be exact. This lining forms a tight intestinal barrier, deciding what gets absorbed into the bloodstream and what doesn’t. Intestinal permeability, better known as “leaky gut,” occurs when the intestinal lining becomes damaged. Cracks or holes form in the lining, allowing for undigested food, toxic waste, and bugs to “leak” into the bloodstream. The leakage can cause chronic inflammation, irritable bowel syndrome, other allergic reactions, and change the gut flora (normal bacteria) in the digestive tract. Changes in the intestinal bacteria and inflammation could lead to the development of several common chronic diseases. With leaky gut, your body cannot absorb proper nutrients. Your leaky gut syndrome treatment diet is crucial, and so is knowing the right supplements to take, including vitamins and probiotic pills or drinkable probiotics.1
What foods should you avoid if you have leaky gut syndrome?
If you have leaky gut, the foods that you eat can directly affect your symptoms. Certain foods have been found to worsen leaky gut symptoms and increase inflammation. These foods should be avoided. You can tailor the guidelines based on your preferences, your specific trigger foods, and nutritional needs. Each individual will have different reactions to foods, so find what works and doesn’t work for you and talk about it with your registered dietitian to avoid any nutritional deficiencies.
Refined Carbohydrates and Sugar
There are several foods associated with leaky gut syndrome known to cause inflammation. These foods should be avoided or limited to help keep inflammation down. Refined carbohydrates such as pastries and white bread can be hard on the gut. This includes cakes, cookies, brownies, and candy. Most processed snack foods and desserts have refined carbohydrates and added sugar. Added sugar in large quantity and any sugar substitutes such as xylitol and sorbitol should be excluded from your diet2.
Red Meat and Processed Meats
Red meat such as beef, pork, lamb, and bison should be limited because of their association with higher levels of inflammatory markers. The tough, fatty cuts of meat are hard to digest and can worsen leaky gut symptoms. Processed meats are also hard on the digestive tract. Hot dogs, sausage, and lunch meats; these are high in sodium, fat and preservatives and low in iron and proteins.
Fried, Fatty, Spicy, and Greasy Foods
Not only are they unhealthy, but foods that are fried, fatty, and full of grease can also be triggers to leaky gut symptoms because they are hard to digest and can cause inflammation. Spicy foods can also be hard on the gut and escalate symptoms3.
Whether or not you are intolerant to lactose, dairy can be triggering for leaky gut symptoms as well as Crohn’s disease symptoms. Dairy products such as full-fat milk and cheese should be limited. Margarine, shortening, and lard should be excluded as well. Dairy alternatives enriched in calcium and in vitamin D could be a good substitute.
What you drink can also play a role in leaky gut. Sodas, energy drinks, and other sugar-sweetened beverages can increase inflammation. Some people have found that caffeinated coffee and tea can worsen their symptoms and avoid those. Research has shown that alcohol has been linked to an increase in leaky gut and might want to be completely avoided4.
If you’re having symptoms, raw fruits and veggies can be triggering because they are packed with fiber and harder to digest. Try cooking the vegetables or blending the fruit into a smoothie instead. This can help with digestibility. Similarly, whole grain foods, like bread and pasta, can be hard to digest when having symptoms, so they might have to be limited during flare-ups.
Which 3 foods are bad for your gut?
As we now know, several foods that are hard on your gut, but some are harder than others.
Studies have shown that red meat can raise levels of trimethylamine N-oxide (TMAO), which is a byproduct of gut bacteria. The negative change in gut bacteria can occur quickly, in as little as two days. Diets high in animal protein can put people at a higher risk for leaky gut and other chronic conditions because of its inflammatory properties. Higher levels of TMAO not only affect your gut microbiota negatively but can also lead to a higher risk of heart disease5.
Researchers looked at the gut bacteria of children in Burkina Faso, Africa, and compared them to the gut bacteria of children in Italy in a 2010 study. The children in Burkina Faso consumed diets high in fiber and more pea protein while the Italian children consumed more meat. The gut microbiota of the children in Burkina Faso was made up of more good bacteria and had lower inflammation than the children in Italy who had more bad bacteria in the gut microbiota and more inflammation6.
Meat may also contain antibiotics that you are ingesting without knowing it. Antibiotics can kill off good bacteria, allowing the bad bacteria to survive and thrive.
Can’t live without meat? Think about eating it less frequently and buy organic meat, confirming labels say “no hormones” and “no antibiotics.”
We all know fried food is not as healthy as fresh vegetables and fruit, but fried food is also harder for the body to digest. Fried food is often made in oils that are heavy with saturated fats and trans fats. A leaky gut diet heavy in fat can alter the balance of bacteria in the gut microbiota and promote the growth of bad gut bacteria3. Leaky gut and other gastrointestinal problems can be a result of fried foods.
A leaky gut syndrome diet high in refined sugars can also lead to an imbalance of bacteria in your gut microbiota. The imbalance can cause inflammation and increased symptoms of leaky gut. Refined sugar has little nutritional value and can even be bleached2.
Foods you should eat
There are foods that have anti-inflammatory properties to them. They should be eaten in abundance because reducing the inflammation in your gut could help rebuild a healthy gut lining and stop further leakage. Green, leafy vegetables can lessen inflammation. Greens such as spinach, kale, and collards are considered leafy greens. Fruits such as strawberries, blueberries, cherries, and oranges have anti-inflammatory properties. Blueberries, apples, and leafy greens are also high in natural antioxidants and polyphenols, which are the protective compounds found in plants. Other foods that reduce levels of inflammation are tomatoes, olive oil, nuts (almonds and walnuts), and fatty fish (like salmon, mackerel, tuna, and sardines)7.
The Mediterranean diet incorporates a lot of anti-inflammatory foods. The Mediterranean diet is rich in healthy oils, fish, vegetables, fruits, nuts, and whole grains. The World Health Organization recognizes the Mediterranean diet as a sustainable and healthy diet8. This way of eating is based on the traditional cuisine of countries bordering the Mediterranean Sea. If eating the Mediterranean way, you should focus on daily consumption of healthy fats, fruits, vegetables, and whole grains. Fish, poultry, and eggs should be consumed a couple of times a week. Eat dairy products in moderation and limit your intake of red meat (beef, lamb, and pork). Make sure to spice it up! Adding spices and herbs reduces the need for salt.
Some other foods that can be eaten to help with leaky gut are poultry (such as chicken or turkey breast), soups, low fat cheese, tofu and other meat alternatives, low-fat yogurts, flax, chia, and other seeds, and probiotic-rich fermented foods (such as yogurt, kombucha, and kefir).
Studies say that probiotics can help with leaky gut and its symptoms. Probiotics, also popular with a SIBO diet plan, are a “good bacteria” that we eat for our health. They are made up of different strains or a combination of strains. Probiotics can help alter and equalize the balance of bacteria in the gut microbiota. The gut microbiota is made up of over 2,500 different species of bacteria, both “bad” and “good.” Leaky gut can be persistent when the balance of bacteria is off. Probiotics can help improve your gut health by remedying the symptoms of leaky gut, strengthening the tissue of the bowel wall, regulating the response of your immune system, and decreasing inflammation. Probiotics may be useful in remedying leaky gut syndrome, but their effectiveness might differ based on the already existing strains in your gut and the ones that you ingest9.
Probiotics can also help form an intestinal barrier and improve the intestinal lining block undigested food particles, toxic waste, and bugs from entering into the bloodstream10. Product research is very important when selecting a probiotic to add to your leaky gut diet plan and finding the one that works best for you. Consider using an evidence-based supplement from Bio K+ probiotics, a unique probiotic formula that helps keep bad bacteria in check and maximizes intake of good bacteria and to balance the intestinal microbiota.
A leaky gut diet can be flexible and personalized based on an individual’s nutritional needs and trigger foods. It may take some time to figure out what foods your body can tolerate and which ones it can’t. Consult a registered dietitian to ensure the compliance with your food intolerances and avoid any nutritional deficiencies.
