Millet

Brown Rice
Millet edges out brown rice with better blood sugar control, more protein, and zero arsenic risk, though brown rice is easier to find and gentler on the thyroid.
Millet wins on most nutritional and safety metrics, but brown rice remains a solid, accessible choice with specific thyroid advantages that keep it competitive.
You gain fiber, protein, and mineral density with millet, but sacrifice some everyday convenience and may need to watch thyroid impact if you overdo it.

Risk profile
Safety & processing
Both are whole grains with minimal processing and no artificial additives, making them clean carbohydrate sources.
Millet
Goitrogenic compounds
mediumMillet contains goitrogens that can interfere with thyroid hormone production if consumed in massive quantities daily, especially in those with existing thyroid issues.
Brown Rice
Inorganic arsenic
highBrown rice accumulates significantly more inorganic arsenic from soil and water than other grains, posing long-term health risks if consumed daily in large amounts.

Final recommendation
Make millet your default grain for its nutritional edge and safety profile, but rotate in brown rice occasionally for thyroid health and convenience.
Practical
Consumer tips
- 1
Rinse brown rice thoroughly and cook it like pasta in excess water to reduce arsenic levels by up to 50%.
- 2
Toast millet in a dry pan for a few minutes before boiling to bring out a nutty flavor and improve texture.
- 3
If you have a thyroid issue, cook millet well and avoid making it your sole grain to minimize goitrogen exposure.
- 4
Rotate your grains! Eating millet, brown rice, quinoa, and oats on different days minimizes the downsides of each.
