A doctor shared the one fruit he claims can deliver a myriad of health benefits for everyone.

Expert in nutrition and wellbeing, Dr William Li, has shed light on the virtues of a “superfruit” which can bolster both gut health and brain function. Just a single portion of this fruit could markedly enhance your gut health “overnight” he suggested while on a podcast hosted by health lifestyle aficionado Kate Middleton, also called @toxicfreewithkb on TikTok.

While chatting with Kate, Dr Li elaborated on how swiftly diet can affect gut health and thereby influence brain chemistry. He contended that one does not require supplements or vitamins, advocating for a primary focus on diet as the cornerstone to better overall wellness.

Dr Li explained: “Well, you eat foods that have fibre and polyphenols, prebiotics, and this had been studied. We now know how quickly it can work. Kiwifruit. A great source of vitamin C but also a great source of dietary fibre.”

He further disclosed results from human research studies: “We know, and this is from human research, that if you eat even one kiwi a day and you measure your gut bacteria from your poop, just eating one kiwi a day will, overnight, improve your gut microbiome.”

Additionally, Dr Li noted on follow-up tests, one would observe “beneficial bacteria growing back” in the gut.

He concluded by stressing the rapidity of recovery, saying: “This result is fast,” and noting that while it’s “quick to damage [gut health] but have a kiwi, you can actually heal it back up and it’s as quick as starting overnight”.

According to NHS guidelines, incorporating specific foods into your diet can improve gut health, such as a balanced mix of fruits and vegetables. The NHS also recommends wholemeal bread, brown rice, beans, and oats as beneficial for the stomach’s microbiome.

The guidance highlights the significance of fibre in one’s diet, stating: “It’s a good idea to try to eat more fibre or roughage, as most people in the UK do not get enough. A diet rich in fibre can help digestion and prevent constipation. Aim for the recommended dietary intake of 30g of fibre a day.”
