Gut Benefits of Walnuts and Seaweed

June 4, 2018 by

Everyone is aware that it is important to have fiber in your diet to optimize gastrointestinal health. Fiber allows the good bacteria in the gut to do its job and break down complex foods, which gives your body the nutrition it needs.

Almonds and cashews are a popular snack, but walnuts are also a great nut to consider. Walnuts provide your body with healthy fats and plenty of fiber, while also benefitting your gut microbiome. Seaweed is also beneficial for gut bacteria because it is able to change bacterial strains to be therapeutic for the body. Eating these two foods to optimize your gut is important because it can then boost your immune system.


Walnuts have some great health benefits. They benefit cardiovascular health by reducing blood pressure and and lowering the risk of heart disease. They are also believed to improve cognitive function and brain health due to their omega-3 fatty acids and antioxidants. Most of the benefits of walnuts are found in its skin.

When it comes to gut bacteria, walnuts improve your gut microbiota, which are the trillions of healthy microorganisms living in your gut. Researchers have found that blood and fecal samples of people who eat walnuts have an increased amount of Clostridium, Faecalibacterium and Roseburia in their gut, which are bacteria that help improve colon health.

Other studies have found that walnuts increase gut bacteria diversity, and researchers have found that less bacterial diversity is associated with fewer incidents of obesity and diseases such as inflammatory bowel disease. Instead, walnuts increase bacteria that are associated with probiotics, which means that walnuts may be an effective prebiotic.

Seaweed can also benefit gut health. Stanford University researchers have shown that seaweed can manipulate animal diets to change their gut bacteria. The team was able to control the amount of bacteria growing in the intestines of mice by changing the amount of carbs in their food and water.

The researchers studied a carbohydrate-active enzyme from seaweed on the human gut, and found that it can be possible to change the gut microbiome in humans in a deliberate manner to improve overall health and fight against diseases.

While very little is known about why certain strains of bacteria are more beneficial to our health than others, it has been speculated that having a dietary boost through foods such as walnuts and seaweed could allow specific beneficial bacterial strains to have an advantage in our gastrointestinal system.

All of this shows that it might be possible for doctors to manipulate the bacteria in the human gut to help benefit long term health.

Some other ways to help your gut flourish aside from eating walnuts and seaweed are to eat fermented foods and prebiotic foods. Fermented foods help to heal damage that has previously been done to the gut and and seal up any places in your gut that are damaged. It is both simple and inexpensive to culture your own vegetables at home, and it is also easy to make your own yogurt, kefir, and even kimchi. These fermented foods are full of good bacteria, and are also effective in detoxifying the body, boosting the immune system, and providing the body with nutrients that it can use. Fermented foods are able to give your body more beneficial bacteria than you can get by taking supplements.

Prebiotic foods are mainly found in foods that contain a lot of fiber. Research conducted in young rats has found that dietary prebiotics have a profound effect on sleep cycles after looking and the cycles of rapid eye movement. Some whole foods that add prebiotic fiber to your diet and improve your microbiome health include apples, Jerusalem artichokes, shallots, green peas, bananas, Burdock root, pistachios, grapefruit, beet root, cashews, Fennel bulb, and pomegranate.

Whatever you do to increase your gut health, whether it is eating more walnuts and vegetables that originated in the sea, cutting out sugar and processed foods from your diet, eating more prebiotic foods, or start experimenting with fermented foods, it is important to start optimizing the health of your gut. Having a healthy gut will improve your immune system, help you fight off diseases, and improve your overall health and well-being in certain ways that you may not even expect.
