Food adulteration is the practice of adding harmful or cheap substances to food to increase profits. It is common in developing countries and reduces the nutritional value of food. Some common adulterants include stones in grains, chemicals to ripen fruit, and mixing decomposed and good produce. Adulterated food can cause health issues like malnutrition and organ damage. Governments and health organizations promote awareness of adulteration and encourage people to check for signs of tampering with their food.
