Ep 34: Alcohol & Health: Its Journey through the Body

How does alcohol really affect your health? Anna is joined by Professor Charlie Knowles, a renowned medic and author, to shed light on the complex relationship between alcohol and our bodies. They explore the popular perception that a glass of red wine a day is beneficial and address its potential role in increasing the risk of serious health issues, including various types of cancer. Together they discuss how alcohol, a Group 1 carcinogen, affects everything from our DNA and gut microbiome to our social behaviours, and touch on the ethical responsibility of the medical profession and the drinks industry to inform the public about these risks, especially against the backdrop of aggressive alcohol advertising. There is a thin line between moderate consumption and dependency, significant global social consequences of alcohol, and staggering costs of alcohol-related harm. So, whether you're curious about cutting back or just want to make more informed choices, stay tuned as we rethink the big drink together!Here are the highlights:03:55 Professor Charlie Knowles' writing his book.13:00 How alcohol spreads through the body and affects it.20:37 Common reflux disease linked to obesity and cancer.32:30 Alcohol benefits for heart health questioned and debated.35:50 Changes in DNA can increase cancer risk.45:54 Know the risks and make decisions.49:07 Dependency, long-term memory and behaviour issues.53:47 Biology and alcohol: understanding addiction.🔗 Get all the free resources from the series at: Toolkit OptinAnna’s group coaching community ‘Unstuck!’ helps identify your alcohol ‘stories’ and beliefs, breaking the cycle of alcohol and all the shame that goes with it.
