Is That Eggnog Going To Make You Feel Sick? Here's What To Look Out For.

Donovan via Getty Images It’s the holiday season. “Think what’s in it: heavy cream, milk, sugar, whipped eggs and alcohol.” And with the recommended serving size a paltry half a cup, eggnog is easy to over-indulge. “For some, the heavy combination of sugar, heavy cream, milk and alcohol could be a disaster waiting to happen,” Tracy Lockwood Beckerman, a registered dietitian, told HuffPost. “Eggnog is made with ‘heavy’ ingredients that, eaten in exclusion of anything else, might cause stomach distress,” registered dietitian Barbara Ruhs said. Frankeny elaborated, “always be aware of an off color, scent or flavor, which may mean your drink has gone bad, even if it’s before the actual expiration date.” You may have seen someone add alcohol to a dubious vat of eggnog and explain that the alcohol has antibacterial properties, so all is well.
