Gut health could be the biggest trend in the health field right now. Everywhere I turn people are discussing the importance of their gut health and how it is linked to their overall health, as well as the benefits of probiotics. And, for good reason: a growing body of research shows that what happens in our gut expands well beyond the gut.
Now new research shows that the health of your gut is significantly influenced by what you eat. A new study assessed 15096 fecal samples provided by 11336 people, published in the journal of the American Society for Microbiology, found some exciting facts about gut health and the microbiome, which is the total of all the microbes in a living being.
We each have a microbiome and no two microbiomes are alike, although there can be some similarities between them. The microbiome is a sort of microbial fingerprint. And, thanks to the new research, we have greater insight into the effect of diet on our microbiome. Here are some of the findings from this exciting study:
1) Plant-based diets produce the most diverse microbiomes. Diverse microbiomes seem to confer health benefits. Consider people who struggle to lose weight: earlier research in the journal Beneficial Microbes shows that they tend to have less diverse strains of beneficial bacteria and a lower ratio of beneficial microbes to harmful ones.
2) Eating more than 30 types of plant foods weekly yields the most diverse microbiome. In other words, it’s important to eat a plant-based diet but also one that has tremendous diversity. So, expand your horizons when it comes to trying new vegetables, fruits, nuts, seeds and grains. Your microbiome will thank you. And, who knows? You might even discover a new favorite food.
3) There is a lower incidence of bacterial resistance in those who eat the greatest variety of plant foods weekly. This is great news since more and more varieties of harmful bacteria like E. coli and MRSA are, not only becoming more prevalent, they are also becoming resistant to the typical drug treatment: antibiotics. This is an astounding discovery on its own. We tend to assume that all of a certain variety of bacteria have the same level of potency against humans, but the research shows that people who eat a large variety of plant-based foods are less likely to be host to these disease-causing, resistant bacteria. People who ate more than 30 types of plant foods weekly had less resistance to antibiotics.
4) The gut bacteria of people suffering from mental health issues, including: post-traumatic stress disorder (PTSD), schizophrenia, depression or bipolar disorder were more similar to others suffering from mental disorders than to those who do not suffer from mental disorders. While the scientists conducting the study did not draw any conclusions, there may be a possible connection between gut health and mental health. Certainly other research suggests that is indeed the case. Research in the Journal of Physiological Anthropology found a link between gut bacteria and increased activity in brain pathways that improve brain health and reduce depression risk.
How can you reap the benefits of this exciting research?
There are endless ways to boost the variety of plant-based foods you consume, but the following ones should help you get started:
- Start by replacing meat in your diet with plant-based options. Start with Meatless Mondays but don’t hesitate to go meatless the rest of the week as well
- The next time you pass by that odd-looking fruit or vegetable in the produce section of your grocery store, add it to your cart. It’s easy enough to find recipes for lesser-known foods using a quick Internet search. And, most importantly, add the food to your diet.
- Instead of just snacking on almonds or another nut, branch out to try Brazil nuts, cashews, hazelnuts, pecans, pistachios, etc. Choose raw, unsalted varieties.
- Rather than just add a can of kidney beans to your soup, stew, or chili, opt for bean varieties you are less familiar with. That could include: chickpeas, lentils, pinto beans, Romano beans, black beans, navy beans, etc.
- The next time a snack attack strikes, choose a piece of fruit or a bowl of mixed berries.
- When you have a craving for salty foods, choose traditionally-fermented pickles, pickled green beans, pickled beets or other foods with live cultures. Not only will you be getting a wider variety and a greater quantity of plant-based foods, you’ll also help expand the beneficial microbes you consume. Be sure to choose pickled foods that state “live cultures” or “unpasteurized” on the label.

Great article, but the idea of eating raw cashews -gave me the shivers — these are in the poison ivy family & if one breaks out from that, they would do so from cashews, too. In point of fact, cashews are tricky to process,
As you might have guess, I’ve encountered raw cashews and had a sever reaction.

While nuts are very healthy- certain nuts can certainly cause issues for many of us … severe reactions are scary!

I’ve heard many people have problems with peanuts, too, but doubt if many realize that cashews can have such a horrible reaction.

Interesting stuff!! I believe mental health ties directly to our gut health. These kinds of studies are invaluable to get closer to the truth. (Although it can’t be pretty, haha!)
