Russia’s war on Ukraine has magnified inflationary shockwaves across the U.S. and the world, including startling price increases for gasoline, oil – and food. Though it's too early to predict how much prices will rise, the cost of corn, barley and other grains is higher. Cooking oil prices, from sunflower to cottenseed, have skyrocketed.
