Doctor shares ‘world's most anti-ageing food' and it's not green tea or kale
A health expert with millions of social media followers has shared the superfood that he says boasts more anti-ageing properties than any other.
Health foods and drinks such as green tea, green vegetables, or chia seeds are often praised for their 'anti-ageing' properties. But a social media doctor has shared one superfood that he says is better than any other in the world for helping you look younger.
Dr Eric Berg is a health expert specialising in intermittent fasting and healthy ketosis. He boasts a whopping 17million subscribers on YouTube and over one million TikTok followers, and he often shares diet advice.
In a recent video on his TikTok page, Dr Berg said: "The number one most anti-ageing food is not kale, it's not green tea, and it's definitely not chia seeds."
"The most anti-ageing food in the world is actually grass-fed liver."
Grass-fed liver is the liver of cattle that have been raised on an exclusively grass from cattle that have been grass-fed is seen as healthier than meat that is grain-fed, which is often fattier and higher in calories.
Dr Berg continued to explain some of the specific health benefits and anti-ageing properties of grass-fed liver.
He said: "It's loaded with all of the B vitamins, zinc, copper, and coenzyme Q10. It has the active form of vitamin A which is called retinol, which is very important for your eyes, the thyroid and your immune system, not to mention your skin."
Studies suggest that liver from grass-fed beef cattle has four times the phytonutrients (health-boosting plant compounds) as livers from grain-fed beef cattle, according to Cleveland Clinic.
Retinol is extremely beneficial for skin health, even reducing signs of ageing and improving overall appearance of the skin, reports Healthline.
While many anti-ageing skin products contain retinol, it's also possible to obtain it through our diets.
Despite its benefits, many of us won't be prepared to regularly purchase, cook and eat beef liver. But it can also be found in supplement form.
Grass-fed beef liver supplements can be purchased from Amazon, with a bottle of 180 Carnivore Go capsules currently £35.99. That 10 per cent discount means you get each tablet for 20p.
Also on Amazon, a packet of 120 Orgenism grass-fed beef liver capsules is £19.99, or 17p per tablet. Holland and Barrett also offer a range of protein powders made from beef which offer similar health benefits for £45.
Speaking further about the health-boosting properties of grass-fed beef liver, Dr Berg added: "It has heme iron, which is the most bioavailable form of iron that prevents anaemia and is loaded with collagen and high quality amino acids, vitamin K2, vitamin E and even vitamin D."
One serving of beef liver (around three ounces) can provide about half the daily iron needed for men and a significant portion for women, according to the Cleveland Clinic.
APE Nutrition also explains that beef liver contains the necessary building blocks and ingredients to support collagen production in the body, which is another recognised anti-ageing protein that can make skin appear firmer and more youthful.
Dr Berg finished: "You can look at liver like a powerful vitamin mineral supplement."
