Each 100g serving provides 3.8g of fiber (14% DV), which adds bulk to stool and feeds beneficial gut bacteria. This can prevent constipation and support a healthy microbiome, but a sudden increase may cause bloating and gas.
With 389mg of potassium per 100g (8% DV), Brussels sprouts help counterbalance sodium's effects by promoting sodium excretion through urine, which can relax blood vessel walls and lower blood pressure.
The 1.4mg of iron (8% DV) in each serving is non-heme iron, which is less absorbable than animal iron. However, Brussels sprouts also contain vitamin C (not listed but present), which can enhance iron uptake when eaten together.
Raw Brussels sprouts contain goitrogens, which can interfere with iodine uptake by the thyroid gland. Eating them raw daily, especially in large amounts, may impair thyroid function in susceptible individuals.
Verdict
Daily Brussels sprouts can improve digestion, blood pressure, and iron status, but eating them raw may pose thyroid risks for some. Cooking them reduces goitrogenic effects while retaining most nutrients.
⚠️ Who Should Avoid
- People with hypothyroidism or iodine deficiency
- Individuals with irritable bowel syndrome (IBS) or sensitive digestion
