8 Healthy Vegetables That Can Sometimes Harm You
1. If you have digestive upset: An unidentified substance in tomatoes and tomato-based products can cause acid reflux. People with digestive upset could try eliminating tomatoes for two or three weeks to see if things feel better.
2. If you take a blood-thinning drug such as warfarin (Coumadin): It’s important to maintain steady blood levels of vitamin K (e.g. kale, spinach, turnip greens) —sudden increases can lessen the effects of the drug.
3. If you have a history of kidney stones: Limit oxalate-rich foods, such as rhubard, spinach, beets, and beet greens.
4. If you have gout: Watch your asparagus intake.
5. If you have certain allergies: Eating such foods as artichokes may provoke an allergic reaction in people who are sensitive to ragweed allergens. People sensitive to latex may have an allergic reaction to avocados. Many people sensitive to aspirin may suffer an allergic reaction to radishes, which contain salicylates, compounds similar to the drugs’ active ingredients.
6. If you have an inflammatory GI disorder: Avoid or minimize your intake of cabbage, which contains bacteria that live naturally in the intestinal tract and cause gas and bloating.
7. If you're watching your weight: Be picky about eggplant-based dishes. Eggplants’ spongy texture soaks up fat. In fact, deep-fried eggplants soak up four times as much fat as French-fried potatoes.
8. If you have an underactive thyroid: Turnips contain two goitrogenic substances, progoitrin and gluconasturtin, which can interfere with the thyroid gland’s ability to make its hormones.
