Fermented £2 food that could help slow ageing and aid weight loss

A £2 jar of fermented food could help you maintain your fitness and wellbeing, with its benefits said to be particularly beneficial for those concerned about ageing and weight management. A traditional Korean favourite, kimchi can be found in numerous UK supermarkets for as little as £2. It's produced by fermenting vegetables such as cabbage, radish and carrots alongside chilli, garlic, ginger and soy sauce. The vibrant and sharp pickle food boasts a deep, savoury umami taste. It's commonly served as an accompaniment, for instance, with Korean fried chicken. If you want to pick some up, you'll find it in your local supermarket like Morrisons , which is selling a jar for £2. You could also pick it up in ASDA , where a jar costs £3.45. The well-loved dish, which is excellent for our digestive system thanks to the fermentation method, may help slow the ageing process. According to specialists at Healthline , a 2025 review suggests that fermented foods, such as kimchi, may promote anti-ageing. This could be because they help manage inflammation. In its findings, the study indicates that consuming fermented foods may assist in slowing ageing by decreasing oxidative stress, supporting the immune system, reducing inflammation, preserving cell balance, and enhancing gut bacteria. These benefits come from both the live microbes in the foods and the helpful compounds produced during fermentation, "including organic acids, phenolic metabolites, polysaccharides, and bioactive peptides." It may help you lose weight, but of course, you need to make sure you are doing other things too in order to support your goals. One study in 2024 found that kimchi increased good bacteria and has a "positive" effect on the gut. This study noted in its conclusion: "Kimchi intake also promotes robust growth of A. muciniphila, a bacterial species associated with anti-obesity effects, while simultaneously reducing Proteobacteria species, often associated with obesity. "Additionally, the weight gain and altered gut microbial composition observed in the placebo group suggest that regular kimchi consumption in Koreans suppresses weight gain and has a positive effect on gut microbial homeostasis. In summary, the positive effects that kimchi has on obesity symptoms appear to be associated with the composition and metabolites of the LAB within kimchi influencing the intestinal microbiota composition." A study of the same year also "also found that kimchi can support weight loss. In the study, men who consumed 1 to 3 servings of kimchi per day had a lower risk of obesity compared with those who consumed fewer than one serving per day. "While more research is necessary, consuming kimchi as part of a diet could help with weight loss or management." According to M&S Food , you can start to incorporate kimchi into your diet with the following meal ideas. With rice Spoon over steamed rice for instant flavour.
