Does leaving fruit and vegetables in the fridge for several days mean they gradually lose all their vitamins? Some nutrients can decline during storage, but the changes vary considerably depending on both the nutrient and the produce. Vitamin C is particularly sensitive, while minerals and fibre tend to be much more stable.
That is the central takeaway from a review published in Critical Reviews in Food Science and Nutrition on 21 June 2026. The research team included scientists affiliated with institutions including INRAE, Université de Montpellier and CTIFL.
What happens to vitamins when fruit and vegetables are stored?
Fresh produce does not become biologically inactive once it has been harvested. Physiological processes continue after harvest, gradually changing some of the compounds found in fruit and vegetables. Refrigeration can slow these processes, but it does not stop them entirely.
The review found an important difference between nutrients. Vitamin C can change substantially during storage, whereas minerals such as potassium and dietary fibre tend to change much less. The researchers also considered vitamins B9, E and K, provitamin A carotenoids including beta-carotene, polyphenols and glucosinolates.
There is therefore no single percentage of vitamins that all produce loses after a certain number of days. The type and variety of fruit or vegetable also have a major influence on its composition.
Does stored produce become less nutritious?
Some nutrients may decline, but that does not mean stored fruit and vegetables suddenly lose their nutritional value.
The authors explicitly conclude that despite relative losses of certain nutrients during storage, the overall nutrient levels remain meaningful. Post-harvest storage is also only one source of variation: species and genotype can have an even greater effect on nutritional composition.
This distinction matters. Finding that vitamin C declines during storage is not the same as finding that vegetables kept for several days have become nutritionally worthless.
The same principle helps when shopping: different produce behaves differently before and after it reaches your kitchen. Ingredient guides such as our pages on carrots, strawberries and apricots can help identify the characteristics of individual foods. These destinations are present in the English TCH ingredient sitemap.
Is the fridge always the best place for fruit and vegetables?
Not necessarily. Refrigeration is useful because lower temperatures can slow post-harvest physiological changes, but different types of produce have very different storage requirements.
The review notes that shelf life can range from just a few days for particularly fragile produce to several months for species suited to longer storage.
The practical question is therefore not simply whether refrigeration preserves vitamins, but where a particular food should be stored. Potatoes and avocados are good examples of foods for which storage conditions matter, and our guide explains how to store potatoes, onions and avocados.
Should you eat fresh produce immediately after buying it?
There is no evidence from this review that fruit and vegetables need to be eaten immediately after shopping to retain worthwhile nutritional value.
Instead, the research describes a gradual and highly variable process. Some nutrients are more sensitive than others, while the characteristics of the produce and its storage conditions also matter.
For everyday use, the takeaway is reassuring: store produce appropriately and use what you have rather than assuming fruit or vegetables become nutritionally poor simply because they have spent a few days at home.
FAQ
Which vitamin is most affected by storage?
Vitamin C is among the nutrients that can show substantial changes during storage. The amount lost varies by produce and storage conditions.
Do vegetables lose fibre while they are stored?
Fibre is considerably more stable than some vitamins. The review reports far smaller changes in fibre and minerals than in vitamin C.
Does refrigeration stop vitamin loss?
No. Refrigeration slows physiological changes after harvest but does not stop them entirely.
Are vegetables still nutritious after several days in the fridge?
Yes. The review concludes that despite relative losses of some nutrients, stored fruit and vegetables retain meaningful nutritional value.
Is freshly bought produce always more nutritious?
Not necessarily in a way that can be generalised. Nutrient composition also varies substantially according to species and variety, so storage time is only one factor.
