1. Potatoes
Why Avoid Them: Potatoes have a high glycemic index, which can quickly spike blood sugar levels. This can be particularly problematic for people with diabetes or insulin resistance.
Dietician Insight: “Potatoes are often consumed in unhealthy forms like French fries and chips, which are high in unhealthy fats and calories,” says Dr. Amy Shapiro, RD. “Even baked or boiled potatoes can cause blood sugar spikes if eaten excessively.”
2. Corn
Why Avoid It: Corn is high in carbohydrates and can lead to weight gain if consumed in large quantities. It is also often genetically modified and may contain high levels of pesticides.
Dietician Insight: “Corn is often processed into products like high-fructose corn syrup, which contributes to obesity and other metabolic disorders,” warns Lisa Young, Ph.D., RD.
3. Peas
Why Avoid Them: Peas are relatively high in sugar compared to other vegetables. They can contribute to blood sugar spikes and are not ideal for low-carb diets.
Dietician Insight: “While peas provide fiber and protein, their high sugar content can be problematic for those managing their blood sugar levels,” explains Keri Glassman, MS, RD, CDN.
4. Eggplant
Why Avoid It: While it is on my list of easiest vegetables to grow in containers, an eggplant contains solanine, a compound that can be toxic in large amounts. It can also cause digestive issues for some people.
Dietician Insight: “Eggplants can be difficult to digest for some people and may cause gastrointestinal distress,” notes Dr. Rachel Fine, RD. “Solanine toxicity is rare but can occur if eggplants are consumed in excessive amounts.”
5. Bell Peppers
Why Avoid Them: Bell peppers are part of the nightshade family, which can cause inflammation and digestive issues in sensitive individuals.
Dietician Insight: “Nightshade vegetables, including bell peppers, can exacerbate inflammation in people with conditions like arthritis,” says Dr. Steven Gundry, MD. “It’s best to avoid them if you have chronic inflammatory issues.”
6. Beets
Why Avoid Them: Beets are high in sugar and can cause blood sugar spikes. They also contain oxalates, which can contribute to kidney stones.
Dietician Insight: “While beets have many health benefits, their high sugar content can be a concern for those managing their blood sugar levels,” says Dr. Marion Nestle, Ph.D., MPH.
“The oxalates in beets can also be problematic for those prone to kidney stones.”
7. Carrots
Why Avoid Them: Carrots are high in sugar compared to other vegetables, which can be a concern for those on low-carb diets or managing blood sugar levels.
Dietician Insight: “Carrots are a great source of beta-carotene, but their sugar content can be an issue for people on low-carb diets,” explains Dr. Robert Lustig, MD. “Moderation is key.”
8. Radishes
Why Avoid Them: When eaten in moderation, radishes are super good. But too much of radishes can cause digestive issues in some people, such as gas and bloating. They also contain goitrogens, which can interfere with thyroid function.
Dietician Insight: “Radishes are a healthy vegetable, but their goitrogen content can interfere with thyroid function, especially if consumed in large amounts,” warns Dr. Josh Axe, DNM, DC, CNS.
9. Tomatoes
Why Avoid Them: Tomatoes, another nightshade family member, can cause inflammation and digestive issues in some people. They also contain solanine, which can be toxic in large amounts.
Dietician Insight: “Tomatoes can be inflammatory for people with arthritis and other inflammatory conditions,” says Dr. Mark Hyman, MD. “If you notice any adverse reactions, it’s best to limit or avoid them.”
10. Spinach
Why Avoid It: Spinach is high in oxalates, which can contribute to kidney stones. It also contains goitrogens, which can interfere with thyroid function.
Dietician Insight: “Spinach is nutrient-dense but should be consumed in moderation by those prone to kidney stones or with thyroid issues,” advises Dr. Michael Greger, MD. “Cooking spinach can reduce its oxalate content.”
