4 Types of People Who Should Be Careful With Cabbage
Cabbage is inexpensive, versatile, and packed with nutrients. It provides vitamin C, vitamin K, fiber, folate, and vitamin B6, and it can be an easy way to add more vegetables to your diet.
It also comes in several varieties, including green, red, purple, and white cabbage. For most people, cabbage can be part of a healthy, balanced diet.
However, cabbage is not necessarily suitable in large amounts for everyone. Certain people may experience digestive symptoms, medication interactions, or concerns related to thyroid and iodine status.
Here are four groups who may need to be more careful.
1. People With Certain Thyroid or Iodine Problems
Cabbage belongs to the cruciferous vegetable family, which also includes broccoli, cauliflower, Brussels sprouts, and kale. These vegetables contain compounds commonly called goitrogens, which can interfere with the body’s use of iodine under certain circumstances.

The
important point is that this does not mean everyone with a thyroid condition needs to avoid cabbage.
According to the National Institutes of Health, reasonable amounts of goitrogen-containing foods are generally not considered a concern for people who get enough iodine. The issue is more relevant to people with inadequate iodine intake or particular thyroid-related circumstances.
People with a thyroid disorder should therefore avoid making very large dietary changes without discussing them with their healthcare professional.
2. People With IBS or Sensitive Digestion
Cabbage can cause gas and bloating in some people, particularly those with irritable bowel syndrome (IBS) or a sensitive digestive system.
Certain carbohydrates and fibers are fermented by gut bacteria, producing gas. In people with IBS, this can contribute to bloating, abdominal discomfort, diarrhea, or constipation.
Interestingly, the amount and preparation can matter. Monash University notes that ordinary cabbage can be low in
FODMAPs at certain
serving sizes, while fermented cabbage such as sauerkraut can have a different FODMAP profile.
If cabbage repeatedly causes discomfort, reducing the portion size or discussing dietary triggers with a dietitian may be more appropriate than eliminating vegetables altogether.
3. People Taking Warfarin
Cabbage contains vitamin K, a nutrient involved in normal blood clotting.
