The first taste of new potatoes often signals the start of summer. They are served at family dinners, barbecues, and gatherings where simple food takes center stage. Yet behind their fresh appeal lies a detail that is often overlooked.
While they are widely enjoyed, new potatoes are not suitable for everyone.
A hidden concern
Early-season potatoes differ from those harvested later in the year. According to Iltalehti and guidance from the Finnish Food Authority, they tend to contain higher levels of naturally occurring compounds such as glycoalkaloids and nitrates.
These substances are part of the plant’s natural defense system. However, in elevated amounts, they can pose health concerns.

The levels are not always noticeable in taste, making awareness particularly important.
Young children at risk
Health authorities advise that children under the age of one should not consume new potatoes. Their smaller body size and developing systems make them more sensitive to these compounds.
In adults, relatively large quantities would typically be required before symptoms appear. For infants, however, much smaller amounts may be enough to cause reactions.
Possible effects include digestive discomfort and, in some cases, impacts on the nervous system.

What to look for
A green tint on potatoes is a warning sign of increased solanine, one of the glycoalkaloids. Such potatoes should be avoided entirely.
Food safety recommendations state that potatoes showing signs of greening, sprouting, or damage should not be consumed by anyone.
For most adults, new potatoes remain safe when eaten in moderation and selected carefully. Understanding the risks ensures they can still be enjoyed responsibly.
