Which food is given as an example of natural toxins present at low levels?

• A. Peach
• B. Bread
• C. Milk
• D. Sugar

Answer: (A)

Many foods have small amounts of natural toxins as part of the plant’s defenses, but these are usually confined to non-edible parts or are present at very low levels in the part we eat. Peaches illustrate this because the seeds contain cyanogenic compounds, such as amygdalin. When a seed is crushed or chewed, these compounds can release hydrogen cyanide, a potential toxin. The flesh of the peach, which is eaten, contains only trace amounts and is generally considered safe, making it a classic example of a natural toxin present at low levels. In contrast, bread, milk, and sugar are not typically cited for inherent natural toxins in their edible forms.
