We are often told to eat our vegetables, and that remains good advice. But a bigger serving is not always a better serving. Some vegetables come with natural compounds or nutrients that may need a closer look when eaten in large amounts or when certain health conditions are involved.
| Vegetable | What to Watch For | Who Should Be More Careful |
|---|---|---|
| Potatoes | Large portions, especially when highly processed or prepared with added fats, can significantly increase carbohydrate and calorie intake. | People with diabetes or those watching their blood sugar or calorie intake |
| Sweet potatoes | High in carbohydrates and potassium and also contain oxalates, which may matter for people prone to calcium oxalate kidney stones. Large amounts of fiber may also cause gas or bloating. | People with diabetes, certain kidney problems, a history of calcium oxalate kidney stones, or frequent gas and bloating |
| Spinach | High in oxalates, which may contribute to calcium oxalate kidney stones in susceptible people. It is also rich in vitamin K, so people taking warfarin should keep their intake reasonably consistent rather than making sudden major changes. | People who have had calcium oxalate kidney stones or those taking warfarin, a blood-thinning medicine |
| Tomatoes | Naturally acidic and may trigger or worsen symptoms in some people with acid reflux. | People with acid reflux or frequent heartburn |
| Cabbage and broccoli | Large amounts may cause gas and bloating because of fiber and fermentable carbohydrates. | People who often experience gas, bloating, or digestive discomfort |
| Carrots | Extremely high and prolonged intake of beta-carotene can cause carotenemia, a harmless yellow-orange discoloration of the skin. | People who regularly eat unusually large amounts of carrots |
No vegetable on this list suddenly becomes “bad food.” What matters is knowing our own health needs and keeping variety on our plates. After all, eating our greens should be part of the menu, not the entire menu.
