Can you identify the major types of bacteria in your gut and how one could eat in a single day to maximize their production of good / beneficial bacteria?

The Major Types of Bacteria in Your Gut

Gut bacteria, also known as gut microbiota, plays a critical role in keeping us healthy. Over 1000 species of bacteria reside in the gut, and the prominent ones include Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria. Each of these types varies in terms of functions and effects on human health (Valdes, Walter, Segal, & Spector, 2018).

Firmicutes

Firmicutes mainly contribute to breaking down carbohydrates and dietary fibers. The amount of Firmicutes in the gut is often directly proportional to a person's body fat ratio (Le Chatelier et al., 2013).

Bacteroidetes

Bacteroidetes are crucial for processing complex molecules to smaller molecules that can be absorbed into the bloodstream. They can also have an impact on the total energy harvested from the diet (Turnbaugh et al., 2006).

Actinobacteria

Actinobacteria are vital for maintaining gut health. They primarily facilitate the fermentation of dietary fiber, and production of important short-chain fatty acids. Some well known probiotics are also a part of this group (Zhao et al., 2018).

Proteobacteria

Proteobacteria, a large bacterial group, includes both beneficial bacteria and some associated with illnesses like Escherichia and Salmonella (Shin et al., 2015).

Eating to Promote Beneficial Bacteria

Maximizing the production of beneficial gut bacteria involves including certain foods in your diet. Here are some suggestions:

Include probiotics

Probiotics like yogurt, kefir, sauerkraut, and other fermented foods assist in boosting beneficial bacteria, especially Lactobacillus and Bifidobacterium (Markowiak & Slizewska, 2017).

Consume prebiotics

Prebiotics, non-digestible food components like dietary fiber, can stimulate the growth of beneficial gut bacteria (Slavin, 2013).

Include whole grains

Whole grains amplify the production of Bifidobacteria, lactobacilli, and other beneficial gut bacteria (Martínez et al., 2013).

Avoid processed foods

Processed foods can increase harmful bacteria and reduce beneficial gut bacteria, which can disrupt the balance in your gut microbiota (Suez et al., 2018).
