Research has indicated that moderate amounts of red wine consumption is correlated with increased diversity in gut bacteria.
One of the characteristics of red wine is that it is rich in a group of micronutrients called polyphenols, particularly when compared to other alcoholic drinks such as beer and white wine. Polyphenols are present in a wide range of plant-based foods and have long been associated with a number of health and wellbeing benefits including improved digestion and cardiovascular health.
A recent scientific study published in the journal Gastroenterology and featured by the BBC, claims that even two glasses of red wine a month might be sufficient to boost gut health. Reports that link alcohol consumption with health benefits are usually treated cautiously, lest they provoke excessive consumption. This research found that in three independent cohort studies, red wine drinkers had greater diversity in helpful gut bacteria than non-red wine drinkers. Although this study demonstrated a simple correlation, the evidence is mounting that a number of physical and mental health conditions (Alzheimer’s disease, asthma, obesity, and even depression) are linked to the range of bacteria in our digestive tract. It should be stressed that none of the participants in the research were identified as ‘heavy drinkers’.
In summary, the initial findings are that moderate amounts of red wine consumption are correlated with increased diversity in gut bacteria. And in turn, increased diversity in gut bacteria is linked to a number of health benefits. However, the wider picture is that the composition of our gut microbiota can be influenced by a range of factors. Therefore any single element, such as red wine consumption must be seen in relation to diet and lifestyle in general.
Polyphenols found in red wine may support oral bacteria able to inhibit tooth decay and gum disease
Moderate red wine consumption has been associated with a range of health benefits. Many of the claims made historically have not been supported by the latest evidence. In any case, increasing alcohol consumption per se could have a negative health impact that outweighs any positive outcome. However research featured by the BBC this week is linking red wine to improved oral health by acting as a probiotic for mouth bacteria.
Recent research into red wine has highlighted the benefits of polyphenols, these are antioxidant compounds present in red wine, thought to fight harmful free radicals in humans. A recent study from Spain indicates that red wine may be able to exert a beneficial influence over damaging oral bacteria. The effect of polyphenols (caffeic and p-coumaric acids) were tested on the bacteria that can harm teeth and causes gum disease. Caffeic and p-coumaric acids were found to be more successful than grape seed and red wine oenological extracts at limiting the ability of bacteria to stick to cells. But when combined with an oral probiotics (streptococcus dentisani), the polyphenols ability to limit the growth of harmful bacteria (streptococcus mutans) was enhanced.
This is an initial study carried out on cells in a lab, not on actual people, it reflects a simplified or reduced approach. Results will need to be replicated in other studies and ultimately with humans. However the important point to take at this stage is that there is some evidence that wine appears to offer probiotic qualities to both mouth and gut bacteria. This isn’t a charter for people to increase wine consumption, the overall effect of drinking wine hasn’t been clearly established and it is likely to be different for each person. However this study offers yet more evidence of the important role of probiotics in human health.
Polyphenols are abundant micronutrients present in a wide range of foods and drinks, not just red wine. The extent to which any individual substance is able to deliver the health benefits of the polyphenols contained within it is still being researched. The ability of our body to digest and make available the polyphenols we consume is a key issue. Other foodstuffs rich in polyphenols include, blueberries, blackberries, cherries, green tea, black tea and coffee.
Show someone your love by taking an interest in their long-term health and wellbeing. Fermentation is a game changer.
The media (traditional and social) are full of valentine news, view and suggestions. Local traders, shops and supermarkets have an overwhelming array of products linked to St Valentine’s day. However the way in which you decide to treat your loved one says a lot about you. Whilst chocolates, Champagne or roses spring immediately to mind they may by simple clichés of what people are supposed to give, rather than lasting indications of love.
Perhaps a different approach would be to offer your partner (and yourself) something likely to offer nourishment and a lasting health benefit. It is easy to overstate the qualities of naturally fermented probiotics. But we can feel confident that they are likely to make a long lasting contribution to wellbeing in a number of ways. Evidence is starting to emerge that positive gut flora, may be correlated with, stable weight, and generally improved physical and mental health across a number of measures.
Clearly probiotics are not just for February the 14th, and moving towards a healthy diet is a long term project. But talking about fermented foods or trying them for the first time, may be a great way of showing your partner that you really care, and that you want them to enjoy the best possible health. When you create fermented foods at home, not only are your own family exposed to the product, but the idea and your positive actions can influence a wide circle of friends. Something that can’t be said of a bottle of fizz or a bunch of roses.
Whatever you do, and whoever you do it with have a great day.
If wine is good for your health, its relationship with gut bacteria may be part of the answer.
One of the rapidly emerging truths about the relationship between our health and gut flora is that it’s not simple to demonstrate causality. Specific food and drinks can be both positive and negative in different ways at the same time Each person may react to substances in different ways dependent on a number of individual factors.
However science can offer general indications (sometimes something more specific) about what might be beneficial. A 2016 study from the University of Groningen, indicated that wine, coffee and tea all appear to have a probiotic effect, increasing the diversity of the bacteria inside our digestive system (microbiome). The quality and quantity of bacteria in the gut microbiome is apparently increased by the consumption of certain drinks. Health studies have for years suggested that wine, drunk in moderation, may be beneficial for your health. It is possible its role in maintaining and increasing helpful gut bacteria might be part of the explanation.
