A clinical study led by Kings College London Professor of Dietetics Kevin Whelan investigated how gut microbes break down almonds to produce butyrate, a specific microbiota product associated with several health benefits.

This new research found that consuming almonds significantly increases butyrate, a type of beneficial short-chain fatty acid (SCFA) produced by microbes in the colon when they digest fiber. Butyrate is the primary fuel source for colonocytes, the cells that line the colon, according to the study funded by the Almond Board of California. 87 healthy adults participated in this 4-week study.

Results from the study showed significant differences in stool frequency as well as significant increases in butyrate in the colon. Other measured outcomes from the study included relative abundance of fecal bifidobacteria, fecal microbiota composition and diversity, fecal SCFAs, whole-gut transit time, gut pH, stool output (both frequency and consistency), and gut symptoms.

More on gut microbiome influences on depression

The influence of genetic variation on the rate of depression ranges from 37% to 48%, showing a strong relation between family history and depression. The gut microbiome can be a promising approach for managing depression.

Gut dysbiosis is associated with major depressive disorder (MDD) by involvement with various aspects of Gut-brain axis (GBA). It promotes neuroinflammation and causes behaviour alteration, according to the September 07, 2022 Science Direct report.

There are three diet metabolites - kynurenine, tryptophan, and propionic acid - that greatly influence the activities of the gut microbiome and the deficiencies of which can contribute to depression. Researchers found that depression disorder also shows gut-brain dysregulation, an increase in inflammatory cytokines in the blood of depressive patients, dysregulation in fatty acid metabolism, neuropeptide, gut hormone and neurotransmitter synthesis, and abnormal immune system activation, as reported by Science Direct.

Subhajyoti De, associate professor of cancer systems biology at Rutgers Cancer Institute of New Jersey together with RWJBarnabas Health, found that microorganisms may be new targets for earlier diagnosis or treatment of pancreatic cancer (1).

According to the October 10 2022 Rutgers University press release, they were able to identify tumor-associated microbes and measure the activity of the host cells at the same time. They examined the microbiome of pancreatic tumors and identified particular microorganisms that are associated with inflammation and poor survival (2).

Short of two weeks earlier, research by Lian Narunsky Haziza, a cancer biologist at the Weizmann Institute of Science in Israel, found that tumors contain millions of microbes and fungi, representing dozens of species, according to a September 29 2022 New York Times article (2).

So-called tumor microbiome is proving so distinctive in each type of cancer that some scientists hope to find early signs of hidden tumors by measuring the microbial DNA they shed into the blood, says the study led by Dr. Haziza.
