What’s in your festive spirit? Understanding alcohol intolerance

Table of Contents

‘Tis the season to be merry’, so the saying goes. And for many of us, merry means a festive glass (or three) of something fizzy, brewed or distilled.

And while it’s not unusual for us to overindulge at this time of year, leaving us nursing a hangover headache, if you find that your favourite tipple isn’t quite getting you into the festive spirit, and you’re experiencing the after-effects of a heavy night after only a drink or two, it might be time to consider what’s in that glass.

What is alcohol?

Alcohol (ethanol or ethyl alcohol) is the ingredient found in beer, wine, and spirits that causes us to feel drunk.

It’s formed when yeast ferments the sugars in different foods. Wine is made from the sugar in grapes, beer from the sugar in malted barley, cider from the sugar in apples, perry from pears and vodka from the sugar in potatoes, beets, or other plants.

Alcoholic drinks can also contain different flavourings from fruits, spices or even dairy, such as in cream liquors.

Common symptoms of alcohol intolerance

While too many top ups can leave us feeling worse for wear, there are some symptoms which can also indicate an alcohol intolerance. These include:

  • Affected breathing
  • Diarrhoea
  • Headache
  • Hives
  • Nausea
  • Red face and flushed cheeks
  • Runny nose

It can be frustrating when you know that you haven’t overindulged but yet, feel as though you have. We tend to write off the symptoms as simply having had one too many, but it could actually be the case that an intolerance is to blame.

What’s in your glass?

When it comes to alcohol, there are several different ingredients which could cause problems for people with food intolerances and sensitivities. We don’t often think about what goes into our favourite festive drinks, but for those of us that struggle with our trigger foods, even a trace can cause trouble.

Ethanol

Beginning with the alcohol itself, the ethanol contained in alcohol also opens up blood vessels and can make symptoms such as asthma, urticaria or rhinitis worse. Alcohol as an ingredient can also increase gut permeability, allowing toxins and bacteria to pass into the bloodstream, increasing the chance that you could develop a food intolerance.

There can be many reasons why people are intolerant to alcohol itself. These include:

  • Being asthmatic
  • Hodgkin’s lymphoma
  • Being of Asian descent
  • Enzyme deficiency
  • Intolerance to histamine
  • Sensitivity to sulphites.

As well as the alcohol, the different ingredients, from fruits to grains, mixed in to flavour your favourite drinks could also be a cause for concern. Some of the common triggers include:

Grapes

The staple of wine, if you have an intolerance to grapes, you may find that even a small glass of wine causes you to feel unwell.

Gluten

Beer is a grain-based beverage made from either barley, wheat, or rye, which means that, if you’re gluten-intolerant, your favourite pint could be causing you more than a regular hangover. Thankfully, there are gluten-free options available on the market.

Yeast

Used to ferment sugars into alcohol, yeast is a common ingredient in all sorts of beverages. But if you find that yeast causes you to feel unwell, you may notice that a wide range of drinks lead to problems. Likewise, fruity drinks could also be an issue as yeast grows on the skin of fruits like grapes, plums, and damsons. If you’re looking to avoid yeast, try opting for clear, distilled spirits such as vodka or gin.

Dairy

Creamy drinks made with dairy are particularly popular during the festive season as we seek something with a little more indulgence. But if you find that cows’ milk tends to make you feel poorly, you may want to think twice about those creamy cocktails.

Happily, thanks to the rise of free from alternatives, there are more substitutes available on the market made with dairy-free swaps, such as almond milk.

What is food intolerance?

Food intolerances can occur when your body’s immune system mistakes a food protein as a threat, releasing antibodies to fight it. This reaction can result in a range of inflammatory symptoms, such as IBS and bloating, headaches, brain fog, skin complaints like eczema or acne, or joint pain. Those who experience food intolerance might have one or more symptoms, ranging from mild to more severe.

Frustratingly, food intolerance symptoms can be delayed by as much as 72 hours, making it difficult to pinpoint the cause and often leading to the wrong ingredients getting the blame. Additionally, it’s not uncommon for food intolerance sufferers to react to between 4 and 6 ingredients

Take control of your diet

Getting to the bottom of a food intolerance can be frustrating. A common recommendation is the elimination diet, where you remove one food at a time for a few weeks to see how you feel. But this process can take a long time. And, although many of us commonly react to a few different ingredients, the elimination diet is often abandoned when the first trigger food is found, leaving an incomplete picture of what’s causing the problem.
