Bowel cancer prevention: Why fibre should be on your shopping list
The real hero of gut health has been hiding in plain sight
While most of us will have enjoyed a few glasses over the New Year period, the evidence is clear that there is no safe level of drinking. This news may be puzzling; wasn’t a glass of wine meant to be good for your heart and health?
Research shows any alcohol is associated with increased risks of various cancers, heart disease, liver disease and mental illness. According to the Cancer Council, some cancers are more closely linked to alcohol consumption than others. These include mouth, pharynx, larynx, oesophagus, breast, bowel and liver cancers.
But it’s not all doom and gloom. By cutting back or giving up alcohol completely, our bodies are capable of healing much of the damage that may have already occurred. For example, scientists have found that the risk of mouth, throat and oesophagal cancers will reduce over time in those who stop drinking compared to those who continue, as does the risk of cardiovascular and liver disease. The message? If you want to reduce your risk of cancer, drink less, and it’s never too late to slow – or stop.
Current medical advice recommends keeping your alcohol consumption down to no more than two standard drinks per day. If you’re drinking wine, a standard drink is 100 ml, which is roughly what your body can metabolise (or break down) in one hour. However, the average serving size in most bars or restaurants is approximately 1.5 to two times this amount. The result? You may be consuming your two standard drinks in one single “serve”. Similarly, a schooner of beer can be roughly 1.6 standard drinks, and a pint can be up to 2.2. So be careful not to equate standard drinks with glasses, pours or servings.
Another thing we often overlook is the large number of calories in alcoholic drinks. Alcohol is inherently full of energy, containing twice the energy per gram as sugar. This energy is surplus and non-essential to our nutritional needs, so contributes to our widening waistlines.
Of Australians aged 15 years and over, three out of four drink alcohol and three million drink at a risky level. With this in mind, it’s good to have a few strategies up our sleeves that we can adopt to minimise harmful effects and protect our long-term health:
Whether you’re concerned about your waistline, cancer risk, general happiness and wellbeing or even your sleep, there are many great reasons to be conscious of how much alcohol you drink. And remember, if you’re struggling with your alcohol intake, always talk to your GP.
