Britons planning their New Year's Day recovery might need to abandon a cherished tradition. New research has declared the classic Full English breakfast as the worst choice for curing a hangover, despite its long-held reputation as the ultimate morning-after remedy.
The Hangover Nutrition Index Findings
The annual Hangover Nutrition Index (HNI), compiled by the health app Lifesum, has delivered a sobering verdict. The study, released on 31 December 2025, analysed the nutritional value of popular hangover meals from ten different nations. Using an AI-powered Multimodal Tracker, it assessed each dish for protein quality, carbohydrate sources, fat types, fibre, vitamins, and minerals.
The UK's beloved fry-up, averaging a hefty 1,000 calories1,100 calories.
What Should You Eat Instead?
So, what tops the list for battling the effects of a night out? The answer is light, fluid-rich soups. Japan's miso soup claimed first place for being high in electrolytes and low in fat. It was closely followed by Korea's vegetable soup with rice and kimchi, praised for its vitamins, minerals, and gut-friendly probiotics. Sweden's light vegetable and fish soup took third, offering a balance of lean protein, fibre, and hydration.
Lead dietitian Rebeka Bereczy explained the science behind the rankings. "Hangover meals are often indulgent, but small tweaks can make a big difference," she said. "For faster recovery after a night out, focus on hydration and electrolytes – salty broths or electrolyte-rich soups restore your body far more effectively than a greasy fry-up."
Why Greasy Fry-Ups Fail
The study concluded that heavy, greasy, or sugary dishes actually worsen dehydration and contribute to energy crashes. Bereczy noted that high-fat, low-fibre meals correlate strongly with next-day fatigue, dehydration, and digestive discomfort. In contrast, meals rich in fluids, electrolytes, and fermented foods support faster recovery and help regulate the gut. Balanced macronutrients and controlled portions can also reduce feelings of "hangxiety" and prevent sudden energy slumps.
The research clearly indicates that for those seeking a swift return to form, reaching for a comforting broth is a far wiser move than piling a plate with bacon, sausages, and eggs.
