India isn’t the only one banning food exports. These countries are doing the same (CNBC) 

CNBC published an article stating that India has banned wheat exports, becoming the latest country to do so as the price of grain surged this year due in part to the Russia-Ukraine war.  The war has triggered a huge spike in wheat prices, with Russia and Ukraine among the biggest exporters of the commodity. Both countries account for 29 percent of global wheat exports. Russia and Ukraine are among the top five global exporters for many important cereals and oilseeds, such as barley, sunflowers, and sunflower oil, as well as maize.
