• Lack of food with high demand and high nutritional value.
• Essential micronutrients are absent. 
• Due to costly fruits and vegetables, people are not able to buy them and suffer from hunger.

Bio-fortification:

• It is a method in which crops are made with high levels of vitamins, minerals, proteins and healthier fats to improve public health.
• It is done to improve the quality and contents of protein, oil, vitamins, micronutrients and minerals in respective crops.
