Research finds a link between Alzheimer's and gum disease bacteria

New research suggests that a type of bacteria involved in gum disease could play a role in the development of Alzheimer's. "The researchers looked at brains of deceased people with Alzheimer's disease and found evidence of Porphyromonas gingivalis (Pg), a type of bacteria that's associated with gum disease. They also found evidence of gingipains, toxic enzymes produced by the bacteria, in brain samples of people with Alzheimer's, Science Magazine reported."

Probiotics for your heart

Mar 2018

Eating yogurt twice a week could reduce risk of heart attack in those with high blood pressure by up to 30% according to a study. The study reveals that consuming at least two servings of yogurt weekly will help lower the risk of women with hypertension suffering a cardiovascular event, like a heart attack or stroke, by as much as 30 percent. The risk is minimized by 19 percent in men.

In summary:

Justin Buendia, a study author from Boston University, shares that the "results of their study reveal significant new data which prove that yogurt can boost heart health. A diet consisting of yogurt, fiber-rich fruits, vegetables, and whole grains can do wonders for an individuals heart health."

The researchers analysed 55,898 women aged 30-to-55 from the Nurses' Health Study and 18,232 men aged 40-to-75 from the Health Professionals Follow-Up Study. All of the study participants had high blood pressure and were followed for up to 30 years. The participants completed food questionnaires, which the researchers used to estimate their average yoghurt consumption.

The findings were published in the American Journal of Hypertension.




Gut colonisation study could lead to gene targeting probiotics.

This is an exciting development. New probiotic products targeting individual genes for gut microbial diversity could be on the horizon after researchers outline a data-based approach that identifies the growth of beneficial microbes. Source: Nutra Ingredients

Probiotics labelled useless, BUT are they?

A new article by BBC on probiotics headlined "Probiotics Labelled Quite Useless" (Sep 2018) basically dismisses the benefits of probiotics because the study failed to find colonization. 

Here lie the issues- it is a serious mistake to confuse colonization with efficacy. 

The team at the Weizmann Institute of Science made their own probiotic cocktail using 11 common good bacteria including strains of Lactobacillus and Bifidobacteria. It was given to 25 healthy volunteers for a month. They were then sedated and samples were surgically taken from multiple places in the stomach and small and large intestines.

The researchers were looking to see where bacteria successfully colonised and whether they led to any changes in the activity of the gut.

The results in the journal Cell, showed in half of the cases the good bacteria went in the mouth and straight out the other end. In the rest, they lingered briefly before being crowded out by our existing microbes.

The findings are challenged by the International Probiotics Association. An article published in Nutra Ingredients called "No BBC, Probiotics are not useless" have an excellent response. Please read it rather than be alarmed by sensational reporting by the media.
