In low-income countries, the emphasis remains on securing sufficient calories to meet basic nutritional needs. However, as incomes rise to mid-levels, there's a noticeable shift towards consuming more protein, often at the expense of grains. This transition signifies a growing appetite for meat or fish.

Meanwhile, in affluent nations, the dynamics of food consumption undergo a transformation. With disposable incomes on the rise, consumers prioritize convenience and variety. This translates into a demand for easily prepared meals and diverse culinary options.

India, in particular, is poised for significant changes. As its population is increasing and incomes increase, the demand for food is expected to soar. Cultural factors influence dietary choices, with a preference for protein sources like dairy and pulses over meat. Despite these shifts, India still trails behind China in daily caloric consumption by approximately 700 calories, highlighting both the challenges and opportunities ahead in meeting the nutritional needs of its growing population.
