A massive new study out of Germany suggests that asparagus may be tied to living longer. The study, which analyzed data from 177,148 adults in the UK Biobank, found that people who liked asparagus had a 31 percent lower risk of death from any cause.
Researchers at Justus-Liebig University of Giessen had participants rate how much they liked or disliked 140 foods, rather than asking them to recall what they ate. This approach sidesteps a common problem in nutrition research, as people often misremember or underreport what they eat.
Over an average follow-up of 3.4 years, more than 3,300 participants died. Researchers compared death rates between people who rated each food highly against those who rated the same food low. A preference for asparagus stood out with the strongest protective association in the entire study.
They ran the numbers through eleven separate sensitivity analyses, adjusting for smoking, existing disease, supplement use, and several other factors. The asparagus finding held up in every single one.
The team also found that a preference for broccoli, spinach, onions, garlic, mushrooms, lentils, black pepper, and extra virgin olive oil tracked with meaningfully lower mortality risk.
Asparagus delivers a distinct nutritional profile compared to more commonly studied vegetables. The vegetable carries meaningful amounts of folate, vitamin K, and prebiotic fiber that feeds beneficial gut bacteria. Antioxidant compounds called saponins show up in unusually high concentration in asparagus.

These compounds have drawn separate research interest for their potential role in inflammation control. Fiber content likely plays a role in the mortality findings too, as large separate meta-analyses covering more than a million participants have already linked higher fiber intake to lower all-cause mortality.
In the middle of this research, it’s clear that this development has practical implications for people looking to make dietary changes to improve their health. Asparagus could be a simple and effective addition to a healthy diet, such as incorporating healthy eating habits into daily life.
Simple ways to make asparagus a regular habit include roasting it with olive oil for an easy, high-flavor side dish. Buying asparagus in season can also provide the best flavor and lowest cost. Adding asparagus to egg dishes or stir-fries can add variety to meals.
According to the report, liking a food and eating a food tend to move together. Prior research comparing preference questionnaires to actual intake backs up that link. In other words, the vegetables people genuinely enjoy tend to show up on their plate most often.
The UK Biobank is one of the world’s largest health resources, providing a wealth of data for researchers to analyze. The study’s use of this database allowed for an examination of the relationship between food preferences and mortality risk.
