The festive season is notorious for its array of calorie-laden fare, but many people could be consuming more unhealthy ingredients through beverages than food without realising it. From boozy concoctions to sugar-packed hot drinks, these seasonal sips can wreak havoc on your digestive system, dental health and waistline, warn health professionals.

These warm, sweetened beverages also prove particularly harsh on teeth, as they coat enamel with syrups that linger far longer than their cold counterparts. This heightens the likelihood of tooth decay and enamel damage, whilst harmful bacteria in the mouth thrive on the constant supply of sugar. Beyond oral health, the sugar, fat and alcohol found in these drinks can spike blood glucose, trigger inflammation, pile on pounds and raise cholesterol - potentially leading to various health complications.

Adrienne Benjamin, Gut Health Nutritionist at ProVen Biotics, highlighted that a Baileys Irish Cream or Baileys Hot Chocolate typically ranks as the most calorie-dense beverage at festive gatherings, cautioning that the elevated sugar, cream and fat levels in Baileys might cushion alcohol's effects whilst pushing the calorie count to a whopping 500 per serving.

She advised: "Festive drinks can be delicious and fun, just be mindful that creamy or sugary options are higher in calories. Lighter cocktails or alternating with non-alcoholic drinks can help you enjoy the season without sky-rocketing your daily calorie intake. And remember, your gut may feel the impact of all alcoholic drinks regardless of calories."

Topping her list of calorie-laden beverages is the timeless eggnog laced with rum or bourbon, alongside white Russian cocktails, snowballs, and fiery margaritas.

Yusra Aydin, a Registered Dietitian and Head of Nutrition at Vivere, highlighted that the harm from these festive tipples extends beyond mere calories. She explained: "Your gut can feel it. A few simple, festive-focused strategies can help you enjoy seasonal treats while supporting your microbiome.

"Alcoholic drinks like mulled wine, spiced cider, and eggnog can irritate the digestive system and contribute to dehydration. Alternate these with sparkling water infused with festive flavours, such as orange slices, cinnamon sticks, or star anise.

"Remember to sip water throughout the day, and consider adding an extra glass of water for every alcoholic drink to stay hydrated and support your digestive system."

Nutritionist Jenna Hope offered additional festive alternatives to The Telegraph, showing how revellers can reduce their sugar consumption whilst keeping the celebrations alive. One of the easiest switches involves preparing homemade eggnog.

A typical serving of shop-bought eggnog contains at least 35 grams of sugar, but crafting your own version gives you control over the sweetness levels. That said, the cream and fat content still means this remains a high-calorie indulgence.

Hope also suggested swapping mulled wine for a lighter red such as pinot noir, or opting for sherry if you fancy something with a touch more sweetness. She highlighted that these tipples typically come in smaller servings, making it simpler to monitor your intake.

For anyone seeking a healthier spin on the traditional Baileys Hot Chocolate, Hope has a personal favourite - a smoothie-style cocktail combining Baileys, banana and peanut butter, blended with ice.

Another simple trick to cut down on sugar is choosing champagne over prosecco, she noted: "At this time of year, it's much better to spend more on better wine and drink less overall."
