It’s hard to resist garlic sometimes, but its pungent smell can often last long on the tongue and what better way to get rid of it than good old yoghurt? Garlic contains a compound called sulfur volatiles that can cause a bad odour after being eaten. Researchers wanted to better understand how yoghurt and its components can eliminate or reduce such strong odours. For the study, researchers from the Department of Food Science and Technology at Ohio State University, Columbus tested the garlic deodourising capabilities of yoghurt and its individual components of water, fat and protein to see how each stood up to the smell. As a result, the team found both fast and protein were effective at trapping garlic odours, leading the scientists to suggest high-protein foods may one day be formulated specifically to fight garlic breath. “High protein is a very hot thing right now – generally, people want to eat more protein,” said senior study author Sheryl Barringer, professor of food science and technology at the university. “An unintended side benefit may be a high-protein formulation that could be advertised as a breath deodorizer in addition to its nutritional claims,” she said. “I was more excited about the protein’s effectiveness because consumer advice to eat a high-fat food is not going to go over well.” In the lab experiment, researchers placed equal amounts of raw garlic in glass bottles and confirmed the smell of the garlic was released in concentrations that would be detected by the human nose. Scientists measured the levels of volatile molecules in gaseous form present before and after each treatment. It was revealed that garlic alone reduced 99 per cent of the major odour-producing raw garlic volatiles. When introduced separately, the fat, water and protein components of yoghurt also had a deodorising effect on raw garlic, but results showed fat and protein performed better than water. Looking at fat’s performance, a higher quantity of butter fat was more effective at deodorisation. The proteins which were studied included different forms of whey, casein and milk proteins, all of which were effective at deodorising garlic. This may be because of their ability to trap the volatile molecules before they are emitted into the air. A casein micelle-whey protein complex performed the best. “We know proteins bind flavour – a lot of times that’s considered a negative, especially if a food with high protein has less flavour. In this case, it could be a positive,” Barringer said. Additional experiments that involved changing the pH of the yoghurt to make it less acidic (4.4 pH to 7 pH) actually appeared to lower the yoghurt’s deodorisation effect on the garlic. However, changing the pH of water did not seem to make any difference on the water’s deodorization effect. “That’s telling me it goes back to those proteins because as you change pH you change the configuration of proteins and their ability to bind. That said we definitely should be looking at these proteins,” Barringer said. “It probably depends on the protein, as well, because different proteins react differently to pH. So that may be an important thing as we look at other proteins for their garlic deodorization effect.” The team also tested the deodorising effect of yoghurt and its components on fried garlic, in the process they found that drying garlic alone can significantly reduce garlic odour. Yoghurt and its individual ingredients neutralised a lower percentage of volatile compounds of fried garlic compared to raw garlic. Study authors think this may be because there were fewer volatiles to trap than were present in the raw cloves. The findings have provided a foundation for future studies on proteins that might help fight the garlic breath. In the meantime, Barringer predicts that Greek yoghurt, with a higher protein profile than the whole milk plain yoghurt used in the study, may be particularly effective at getting rid of garlic breath. Fruit-flavoured yoghurts will probably work, too, she said – and whatever is used, it must quickly follow ingestion of raw garlic. “With apples, we have always said to eat them immediately,” she added. “The same with yoghurt is presumed to be the case – have your garlic and eat the yoghurt right away.” The study was published in the journal Molecules.

Tracey Emin has opened up about “totally accepting death” when she was diagnosed with an aggressive form of bladder cancer in 2020. In June 2020, visual artist Emin was diagnosed with cancer, and subsequently underwent a series of major surgeries, including a full hysterectomy, as well as the removal of her urethra, bladder, lymph nodes, and part of her vagina and intestine. In April 2021, she shared that the cancer was “gone” after the surgery. In a new interview with The Times, Emin, 60, explained that upon her diagnosis, she was told that there was no guarantee the surgery would be successful in removing the cancer. At the time of her diagnosis, Emin said that she had feared being “dead by Christmas”. As a result, the Turner Prize nominee explained: “I totally accepted death – absolutely, totally.” “I think accepting death on such a profound level was what’s kept me alive,” she said. “I thought, you know what? Death looks after itself. We all die – now I’ll look after living. “I realised that my life has never really been living. I’ve been just dying. I’ve been so nihilistic. I thought, this is gonna change – if I get through this I want to look forward to things and I want to be present.” Emin, 60, now has a stoma (an opening on the abdomen connected to the urinary system allowing waste to be diverted out of the body) and uses a urostomy bag, which she will need to use for the rest of her life. On International Women’s Day in March, Emin penned a powerful personal essay in The Independent about her relationship with her body after surgery. Here, the artist admitted that she “hated” her bag, “but most days I’m philosophical; knowing that it keeps me alive”. She recalled: “One of my greatest golden moments was when my entire bag came off in Chanel on Bond Street: a tsunami of p*** cascading down my body crashing to the champagne-carpeted floor. Everyone was lovely and understood, Chanel even sent me a beautiful bouquet of flowers.” For the article published in The Independent, Emin created an exclusive acrylic on canvas artwork, titled “Marriage to Myself”. She also shared a candid photograph of herself standing in front of a full-length mirror with her white urostomy bag visible. While Emin works almost exclusively in the paint medium now, in June she unveiled three bronze doors that she secretly worked on for the re-opening of the National Portrait Gallery following a substantial £44m redevelopment. Etched in individual panels on the doors are 45 female faces, which Emin explained were inspired by facets of her “soul”. Emin said that her arrangement with the National Portrait Gallery was that she was not paid for the work (the gallery only paid the production fees), in exchange for total creative freedom. “It wasn’t a commission,” she explained. “I did it for free. I think the gallery wants to push the idea of portraiture in a different way. “There’s so many different ways to experience somebody’s, let’s say, soul. It doesn’t just have to be what they look like. It could be a portrait of the soul, for example. It could be lots of different things. So I think they wanted it to move away from the idea of classic portraiture. To stretch it.”
