Taking care of the microbiota can help fight frailty in old age; look how

The study highlights special fibres, responsible for the balance of bacteria in the intestine, as allies against mobility disorders and malnutrition among the elderly

In the spotlight of science for several decades, the intestinal microbiota is gathering evidence of its relationship with the immune system emotional well-being and also against obesity. Now, a study published in the scientific journal The Journal of Clinical Investigation highlights another possible benefit: contributing to the quality of life of elderly.

Chinese scientists carried out an observational analysis on 1,693 elderly people, divided into three groups, depending on the presence or absence of frailty (non-frail, pre-frail and frail). For the classification, they considered characteristics such as weight loss, physical decline, slower walking, decreased hand grip strength and increased exhaustion. In the second phase of the study, biological and metabolic aspects between classes were evaluated, including investigations of the microbiota.

The third phase consisted of a double-blind, randomized clinical trial. In this phase, some participants consumed, for 12 weeks, a preparation of special fibers with prebiotic action, i.e. they contribute to the proliferation and activity of beneficial bacteria. The other received a placebo for control and comparison at the end of the study.

Ecosystem in balance

Several studies show damage linked to dysbiosis, or imbalance in populations bacteriawith a higher concentration of pathogenic bacteria compared to the “good” ones. In this scenario, the permeability of the gut ends up being compromised, allowing harmful microorganisms to travel through the circulation, which can trigger inflammation, among other ailments.

Focusing on a menu rich in fruit, vegetables, whole grains and legumes is one of the strategies for keeping everything in harmony. Such foods offer so-called prebiotic fibers. “Within this group are fructo-oligosaccharides (FOS), present in onions, yacon potatoes, asparagus, tomatoes, among others,” explains nutritionist Einstein.

Also noteworthy are galactosoligosaccharides (GOS), present in milk, including breast milk. Another example is inulin, obtained from artichokes and chicory. “There are also studies that show that substances called flavonoids, coming from cocoa, can have prebiotic effects,” adds Gabriela Mieko.

Finally, add to the list the psyllium. “It is a natural fiber extracted from the seeds of a plant, the Ovate plantainand has been used extensively in studies,” he says. It requires professional guidance for consumption, as excess can cause abdominal discomfort, such as gas and constipation.

Other great allies of the microbiota are probiotics. According to the definition of the National Health Surveillance Agency (Anvisa), probiotics are “live microorganisms which, administered in adequate quantities, bring benefits to the individual’s health”.

They appear in fermented foods, such as specialty yogurts, kefir, kombucha, among others. One thing to watch out for is to pay attention to the information on labels and favor products with lower sugar levels, additives and a shorter ingredient list.

Taking care of this ecosystem ensures the production of short-chain fatty acids (SCFA) – butyrate, acetate and propionate -, which allows for better use of mineral salts and other nutrients. These substances help reduce the risk of deficiencies and, according to some studies, also have anti-inflammatory effects.

Regardless of age, there are many good reasons to pay special attention and keep your gut microbiota healthy.
