Brain health. Promising prebiotics and probiotics combination

According to new research, the bacteria in our gut, known as gut microbiota, play an important role in brain injury and healing after a stroke.

Taking particular types of prebiotics and probiotics can help with brain injury, inflammation, gut bacteria imbalances, and intestinal health.

However, we still don't know whether prebiotics, probiotics, or synbiotics (a combination of both) perform best for particular conditions, or how they operate.

In this study, scientists tested a new synbiotic formulation containing multiple strains of probiotics

Lactobacillus reuteri UBLRu-87
Lactobacillus plantarum UBLP-40
Lactobacillus rhamnosus UBLR-58
Lactobacillus salivarius UBLS-22
Bifidobacterium breve UBBr-01
and prebiotic fructooligosaccharides (FOS)

FOS are extracted from the blue agave plant and fruits and vegetables such as bananas, onions, chicory root, garlic, asparagus, jícama, and leeks. Some grains and cereals, such as wheat and barley, also contain FOS. The Jerusalem artichoke and its relative yacón, together with the blue agave plant, have been found to have the highest concentrations of FOS of cultured plants. (See more)

They used a rat model of stroke called middle cerebral artery occlusion (MCAO).

Before producing a stroke, they gave the synbiotic to the rats for three weeks.

Three days after the stroke, the rats' sensory and motor abilities improved by the synbiotic treatment.

It halted the death of brain cells in the damaged area and
Diminished the extent of the stroke's brain damage.

The synbiotic therapy also

Restored the levels of proteins that support intestinal integrity
Reversed the elevated amounts of certain proteins and chemicals linked to brain inflammation and cell death.
Increased the abundance of good bacteria
Reduced harmful bacteria

Rats, not human beings, but these findings suggest that the new synbiotic preparation has the potential to improve neurological dysfunctions caused by stroke by influencing the communication between the gut and the brain in rats.

Sweetener Reformulated Biscuits: A Step Towards Blood Glucose Control

In a recent study led by Catherine Gibbons from the University of Leeds, the effects of sweetener reformulated biscuits on appetite and endocrine responses in adults with overweight or obesity were evaluated. This study, conducted between 2021 and 2022 in England and France, sheds light on the potential benefits of substituting sucrose with sweeteners like neotame and stevia rebaudioside M (StRebM). The findings suggest that while the reformulated biscuits yielded similar appetite responses compared to sucrose-sweetened ones, they demonstrated a significant advantage in terms of post-meal insulin and glucose levels. Participants consuming biscuits with neotame and StRebM experienced lower postprandial insulin levels compared to those consuming sucrose, indicating a potential positive impact on blood glucose control. This is particularly noteworthy in the context of individuals at risk of developing type 2 diabetes. However, it's essential to acknowledge the limitations highlighted ...

Los no fumadores engordan menos

Un nuevo estudio relaciona el tabaquismo con la ganancia de peso, y concluye que las personas fumadoras activas, no sólo las que lo dejan, engordan más que las no fumadoras. Después de cuatro años de análisis en la Universidad de Navarra, las personas que menos engordaron fueron las que nunca habían fumado.
