Many people enjoy hot chocolate, eggnog, mulled cider, spiced lattes and other seasonal beverages each winter. Comforting as they are, these drinks often contain high amounts of added sugar — and over time that extra sugar may contribute to weaker bones.
Bones store calcium, support the body, protect organs and house marrow. When bone density falls (osteoporosis), fracture risk rises and posture can change, so preserving bone strength matters.
Registered dietitian Kezia Joy says excess sugar can indirectly harm bones. Diets high in added sugar may increase calcium loss in urine, leaving less calcium available to maintain bone density. Frequent blood sugar spikes may also interfere with vitamin D function, which can reduce calcium absorption from food. Early research, including some animal studies, links vitamin D and blood sugar regulation, but findings are still evolving. High sugar intake can also encourage low-grade chronic inflammation, which may disrupt normal bone remodeling. Joy recommends moderating high-calorie, high-sugar items over the holidays.
Dietitian Hannah Anderson points out that a drink’s overall impact depends on its full ingredients. For example, hot chocolate made with milk supplies calcium that can offset some sugar’s effects, but many store-bought mixes provide 20–30 grams of sugar per serving. Traditional eggnog is calorie-dense—often 300+ calories and more than 20 grams of sugar per cup—though it delivers calcium and protein from milk and eggs. Mulled wine and cider can offer antioxidants from spices but include alcohol, which impairs calcium absorption, plus added sugars. Specialty seasonal coffee drinks (peppermint mochas, gingerbread lattes) can contain 50 grams of sugar or more in large sizes, contributing little beyond small amounts of milk.
To limit potential harm, follow added-sugar guidelines. The American Heart Association recommends no more than about 36 grams (9 teaspoons) daily for men and 25 grams (6 teaspoons) for women. Added sugars appear on labels as sugar, syrup, nectar, juice, sweetener or names ending in “-ose” (fructose, sucrose, dextrose).
Practical swaps and strategies:
– Make hot chocolate with unsweetened cocoa and low-fat milk, sweetening lightly with honey, maple syrup or a non-nutritive sweetener (stevia, monk fruit).
– Choose lower-sugar store mixes or stir collagen or bone broth into milk or water for more protein and less sugar.
– Try mushroom-based cocoa blends or other functional mixes that have less added sugar.
– Recreate mulled-cider flavors with unsweetened apple-cider tea blends or homemade spiced apple drinks using cinnamon, cloves, star anise, lemon juice and a splash of apple cider vinegar instead of added sugar.
– When ordering coffee, ask for reduced sweetness (‘one pump’ or ‘half sweet’), skip whipped cream, choose low-fat milk for calcium without excess saturated fat, and add cinnamon or cocoa for flavor.
– Lighten eggnog by cutting added sugar or using lower-sugar recipes, and consider fortified unsweetened plant milks or herbal/low-sugar seasonal drinks for flavor without the sugar load.
Choosing beverages that provide protein and minerals rather than excessive sugar helps keep nutrient levels steady and reduces calcium loss. With moderation and simple swaps, you can still enjoy holiday flavors while supporting bone health.
