What vegetables are poisonous?

Answered by Douglas Hiatt

There are indeed some vegetables that have parts that are poisonous and can be harmful if consumed. It’s important to be aware of these vegetables, especially if you have young children or animals at home. Here are seven kinds of produce with poisonous parts:

1. Apple seeds & stone-fruit pits: While apples and stone fruits like cherries, peaches, and plums are generally safe to eat, their seeds and pits contain a compound called amygdalin, which can release cyanide when ingested in large quantities. It’s best to avoid consuming these seeds and pits.

2. Undercooked kidney beans: Kidney beans are a nutritious legume, but they contain a toxin called lectin. If kidney beans are not cooked properly, this toxin can cause digestive upset, including severe nausea, vomiting, and diarrhea. It’s important to fully cook kidney beans to neutralize the toxin.

3. Tomato leaves, roots & stems: The leaves, roots, and stems of tomato plants contain alkaloids, such as solanine and tomatine, which can be toxic if consumed in large amounts. While ripe tomatoes themselves are safe to eat, it’s best to avoid ingesting other parts of the plant.

4. Sprouted potatoes: When potatoes start to sprout, they produce a natural toxin called solanine. This toxin can cause symptoms such as nausea, vomiting, and even neurological issues if consumed in large quantities. It’s advisable to remove any sprouts or green parts before cooking or eating potatoes.

5. Rhubarb leaves: Rhubarb is a popular vegetable used in pies and desserts, but its leaves contain high levels of oxalic acid and anthraquinone glycosides, which can be toxic if ingested. It’s important to only consume the stalks of rhubarb and discard the leaves.

6. Asparagus berries: While asparagus itself is safe to eat, the berries that grow on the female plants are toxic and should be avoided. These berries contain small amounts of toxins that can cause gastrointestinal distress if consumed.

7. Certain varieties of mushrooms: While mushrooms are generally safe to eat, it’s crucial to be cautious when foraging for wild mushrooms, as some varieties can be highly toxic. It’s best to purchase mushrooms from reputable sources or consult with an expert before consuming wild mushrooms.

It’s important to note that while these vegetables may have poisonous parts, they are generally safe to consume when prepared and eaten correctly. However, it’s always wise to exercise caution, especially if you have young children or pets at home.
