One of the main disadvantages of sorghum is that it can cause allergic reactions in some individuals. This is because sorghum is a grass, and like other grasses, it contains proteins that can trigger allergic responses in susceptible individuals. Food allergies to sorghum can manifest as tingling or itching of the mouth, swelling in and around the mouth, abdominal pain, nausea, vomiting, and even fainting.

Another disadvantage of sorghum is its relatively low nutritional value compared to other grains. While sorghum is a good source of fiber and certain minerals like phosphorus and potassium, it is lower in protein compared to wheat, rice, and corn. This can be a drawback for individuals who rely on sorghum as a staple food and need higher protein intake.
Additionally, sorghum has a tough outer layer called the bran, which can be difficult to digest. This can lead to gastrointestinal discomfort and may require additional processing or cooking methods to improve digestibility.
Furthermore, sorghum has a naturally occurring compound called tannins, which can inhibit the absorption of certain nutrients like iron and zinc. This can be problematic for individuals who rely heavily on sorghum as their main source of these essential minerals.
In terms of culinary uses, sorghum has a bland and slightly nutty flavor, which may not appeal to everyone. It also has a somewhat chewy texture, which can be less desirable in certain recipes or food preparations.
Lastly, sorghum is not as widely available or popular as other grains such as wheat, rice, or corn. This can make it harder to find in grocery stores and may limit the variety of food products and recipes available to individuals who prefer or need to consume sorghum.
Overall, while sorghum has its benefits such as being gluten-free, resilient to drought, and having a low glycemic index, it also has some disadvantages including potential allergenicity, lower nutritional value compared to other grains, digestibility issues, inhibiting certain nutrient absorption, and limited availability.
