What are the potential side effects of drinking too much peach juice?

Peach juice tastes sweet and is easy to drink in large amounts. This page uses USDA figures for canned peach nectar, the closest USDA entry, and NHS advice on juice. A carton of 100% peach juice may have different figures, so read your label.

Too much sugar and calories

USDA lists canned peach nectar with added vitamin C at 50 kcal and 11.93 g carbohydrate per 100 g. A cup (220 g) has about 110 kcal and 26 g carbohydrate. The NHS advises adults to keep free sugars to 30 g a day. Sugars in fruit juice count as free sugars, so a large glass can use up most of that.

Teeth

The NHS says sugars released when fruit is juiced can damage teeth, and advises drinking juice with meals rather than between them.

How much is enough?

The NHS counts 150 ml of fruit juice as one of your 5 A DAY, but only once a day, however much you drink. It advises limiting juice and smoothies to a combined 150 ml a day.

What peach nectar does provide

A cup of peach nectar with added vitamin C has about 66 mg of vitamin C (USDA). The fibre is low (0.1 g per 100 g), so whole peaches are more filling.

Quick summary

• Main drawback: sugar and calories (about 110 kcal per cup, USDA nectar).
• NHS: 150 ml of juice a day at most.
