Does alcohol prevent food poisoning? 3 Scientific facts about the protective effects of alcohol consumption

There’s a common myth floating around that drinking alcohol with your food—especially when traveling or eating street food—can help kill off harmful germs and prevent food poisoning. While it might seem logical that alcohol could “disinfect” your digestive tract, the reality is a lot more complicated. Dr. Alexander Shapsis of Atlantic Gastroenterology encourages patients in the Brooklyn, New York area to educate themselves better on this common myth. Let’s break down what research actually says in simpler terms.

1. A few studies show some protective effects, but only in specific situations

Some scientific studies have found that alcohol might help reduce the risk of certain food-borne illnesses, but only under very specific circumstances. For example, in one outbreak where people got hepatitis A from eating contaminated oysters, those who drank alcoholic drinks with at least 10% alcohol seemed less likely to get sick. In another case, alcohol consumption was linked to a lower chance of getting sick from Salmonella during a food poisoning outbreak.

These findings suggest that alcohol may have a slight protective effect when consumed at the same time as contaminated food. However, this doesn’t mean alcohol is a foolproof or recommended way to prevent food poisoning.

2. Alcohol does more harm than good to your body’s defenses

Even if alcohol shows some benefit in a few isolated cases, using it as a strategy to prevent food poisoning is not wise. In fact, alcohol can do more harm than good to your immune system and digestive health over time.

When consumed regularly or in large amounts, alcohol can weaken your immune system, making it even easier for infections to take hold. It can also damage the lining of your stomach and intestines, making it easier for bacteria and viruses to enter your body.

Another important point is that alcohol can disrupt the healthy balance of bacteria in your gut, which scientists call the “gut microbiota.” A healthy gut helps protect you from infections, so upsetting this balance actually increases your risk of getting sick. Alcohol can also make your intestinal walls more permeable (sometimes referred to as “leaky gut”), allowing harmful substances to pass into your bloodstream.

3. The real way to prevent food poisoning

The safest and most effective way to avoid potential food poisoning is through proper food hygiene and handling. This includes:

• Cooking food thoroughly, especially meats and seafood.
• Washing your hands before eating or preparing food.
• Keeping raw and cooked foods separate.
• Making sure dairy and meat are kept refrigerated.
• Drinking clean, safe water.

The bottom line

While alcohol may offer a very minor protective effect in rare situations, it is not a reliable or healthy method for preventing food poisoning. In fact, relying on alcohol could give a false sense of security while potentially weakening your body’s natural defenses.
