Here's what she eats in a day to stay healthy, youthful and glowy."If you knew what her diet was like, you would be very shocked. I don't know anyone who eats as healthily as she does."One of the 73-year-old's breakfast go-tos is probiotic-rich yoghurts. Probiotics, as defined by the NHS, are "live bacteria and yeasts promoted as having various health benefits".Experts explained: "Probiotics are thought to help restore the natural balance of bacteria in your gut (including your stomach and intestines) when it's been disrupted by an illness or treatment."In 'The Role of Probiotics in Skin Health and Related Gut–Skin Axis: A Review', published in the National Library of Medicine, experts confirmed that probiotics can be a useful tool for skin improvement.They said: "Recent studies have shown that intestinal microbiota homeostasis can influence skin health, demonstrating the existence of a gut–skin axis."Recently, improving skin health through probiotic interventions has been proposed, and micro-ecological skin care is becoming a popular concept."By regulating skin health and gut-skin axis interactions, probiotics can be used as potential management tools to suppress and improve skin diseases in multiple ways, including decreasing oxidative stress, suppressing inflammatory responses, and keeping immune effects."Good probiotic food choices include yoghurt, kefir, kombucha, sauerkraut, pickles, miso, tempeh, kimchi, sourdough bread, and some cheeses, according to experts at Harvard Medical School.The experts at Este Medical Group also confirmed that the gut and skin are interlinked, advising skin care enthusiasts to "nurture their gut for radiance".They cautioned: "A bad diet and unhealthy gut environment can have a negative impact on your skin. An unhealthy gut can be linked to skin conditions like acne and skin inflammation, dull skin, eczema, rosacea, psoriasis and alopecia, for example."When the internal workings of the body, especially the digestive tract and stomach, are unhappy, your body often tries to alert you to problems deep below with spots and pimples, as well as with the skin irritations mentioned above."To combat this, skin care enthusiasts are advised to add probiotic-rich foods to their diet, and prioritise whole rather than processed ingredients, as these "disrupt the natural gut flora".LATEST DEVELOPMENTSThe 73-year-old swears by probiotics, which 'help restore the natural balance of bacteria in your gut'GETTY IMAGESAside from probiotics, other foods the septuagenarian enjoys are fruits, vegetables, and protein sources such as eggs, beans, fish and meat - "she eats a lot of it".As well as enjoying a healthy diet, the 73-year-old practises a 10-second facial yoga exercise that eliminates turkey neck.Turkey neck refers to the loose, saggy and wrinkled skin below the neck, and is a common sign of ageing.For more information on probiotics, Britons can consult the NHS' dedicated webpage, which includes issues to be aware of before taking them.If you have an existing health condition or a weakened immune system, it's important to consult your doctor before taking any probiotic supplements.
