Sorghum
Sorghum is a gluten-free grain crop cultivated worldwide, used as flour, whole grain, or syrup. It is notable for its fiber content and moderate glycemic response compared to refined grains.
Also known as: Sorghum bicolor, great millet, durra, jowar, sorghum grain

Sorghum is an annual grass crop (Sorghum bicolor) native to Africa and now grown widely in the Americas, Asia, and Australia. It appears in food markets as whole grain, flour, flakes, and syrup. In the United States, sorghum grain is used primarily as animal feed and biofuel, but in other regions—particularly Africa, Asia, and parts of the Middle East—it serves as a staple carbohydrate source and is milled into flour for porridges, breads, and traditional dishes. Sorghum syrup, made from the plant's juice, is a traditional sweetener in some cultures.
Sorghum grain contains approximately 9–12 grams of protein per 100 grams of raw grain, along with about 6–7 grams of dietary fiber when consumed whole. It is naturally gluten-free and does not contain compounds known to damage the small intestine in celiac disease or non-celiac gluten sensitivity. The grain's bran and germ layers contain phenolic compounds, including tannins and anthocyanins, which have antioxidant properties. When consumed as whole grain, sorghum does not create rapid spikes in blood glucose compared to white rice or refined wheat flour; glycemic index values vary with variety and processing, typically falling in the moderate range of roughly 55–77.
Blood Sugar and Glycemic Response
Whole-grain sorghum has a lower postprandial glycemic response than refined grains due to its intact fiber matrix and carbohydrate composition. Studies using human subjects show that sorghum-based products produce a smaller rise in blood glucose than equivalent portions of white bread or regular pasta. This is attributed to both the soluble and insoluble fiber present and the physical structure of the grain, which slows starch digestion. Sorghum's response is broadly comparable to whole wheat, though published glycemic index values vary depending on the variety and preparation method. People managing blood-sugar levels may find whole sorghum a reasonable grain choice, though portion control remains relevant for all carbohydrate-containing foods.
Tolerance and Considerations
Sorghum is well-tolerated by most people and poses no common toxicity risk when consumed in normal food quantities. Because it is gluten-free, it is suitable for people with celiac disease or gluten sensitivity. However, some sorghum varieties contain tannins—particularly red and brown varieties—which can bind minerals like iron and zinc if consumed in very high quantities; this is unlikely to be a problem with typical dietary intakes. Individuals with a specific sorghum allergy, though rare, should avoid it. Sorghum is not a significant source of histamine or a recognized migraine trigger. No established upper limit exists for sorghum consumption; it can be used in place of conventional grains in standard portion sizes.
Frequently Asked Questions
Is sorghum safe for people with celiac disease?
Yes. Sorghum is naturally gluten-free and does not contain the proteins that trigger celiac disease. It can be incorporated into a gluten-free diet as a grain alternative to wheat. Note that gluten-free baking with sorghum flour may require recipe adjustments rather than a direct 1:1 swap. Also, cross-contamination during processing is always a consideration; buy certified gluten-free sorghum if this is a concern.
Does sorghum spike blood sugar?
Whole-grain sorghum has a moderate glycemic index—published values typically range from roughly 55 to 77 depending on the variety and preparation method—and generally produces a lower blood glucose response than white bread or white rice. The intact grain structure and fiber content slow starch digestion. Sorghum flour or refined sorghum products may behave more like refined grains; whole grain forms are preferred for blood-sugar stability.
Why is sorghum not widely eaten in the US?
In the United States, sorghum is primarily grown as animal feed and for biofuel rather than human consumption, reflecting historical agricultural practices and market demand. In Africa, Asia, and the Middle East, sorghum remains a staple grain. It is available in US health-food stores and specialty markets as flour and whole grain but is less mainstream than wheat or rice.
Can sorghum cause digestive issues?
Sorghum is not known to cause digestive distress in most people. If switching from refined grains to whole-grain sorghum, the increase in dietary fiber may cause temporary bloating or changes in bowel habits; this typically resolves as the digestive system adapts. Adequate hydration supports fiber tolerance.
