Harvesting Sustenance: The Vital Role of Crops in Global Food Security

Crops are of paramount importance for food production, serving as the primary source of sustenance for humanity. They provide essential nutrients in food, including carbohydrates, proteins, and vital vitamins, in our daily diets. Effective crop management is central to addressing global food security and ensuring a stable supply of nourishing food.

Exploring the Spectrum of Nutrients in Food for Optimal Health

  • Varied Ingredients: Food is generally made of many ingredients. Ingredients contain some components that are needed by our body. These components are called nutrients.
  • Major nutrients are listed as follows:
    • Carbohydrates
    • Proteins
    • Fat
    • Vitamins
    • Minerals
    • Dietary fibre
    • Water
  • Types of Carbohydrates: There are generally two types of carbohydrates in food:
    • Starch
    • Sugar

Exploring the Diversity of Nutrients in Food Through Identification Tests

  • Test to see if the food contains carbohydrates: If the colour of (Food + Dilute Iodine solution) changes to blue black then it indicates that the tested food has Starch or Carbohydrates.
  • Test to see if the food contains Protein in fats: Take a food item and crush it, if an oily patch is found in the crushed food, then it indicates food has fats.
  • Test to see if the food contains Protein in food: If the colour of (food item + solution of copper sulphate + caustic soda) changes to violet , then It indicates tested food has Protein.

Need of Nutrients in food:  Exploring Nutrient Sources for Energy, Growth, and Defense Against Disease

  • Sources of Energy: Carbohydrates and fats mainly provide energy to us. 
    • Carbohydrate Source:  Carbohydrates and fats mainly provide nutrients in food. Carbohydrate sources include Sweet Potato, Potato, Sugarcane, Papaya, Melon, Mango, Maize, Bajra, Rice, and Wheat.
    • Higher Energy: Fat has much more energy than carbohydrates. We get fats from both plants and animals. 
    • Sources of Fat: Plant sources of fats are Sunflower Oil, Groundnut Oil, Mustard Oil, Coconut Oil, Soybean Oil and the animal sources are Meat, Fish, Eggs, Ghee, Butter and Cream.
    • Energy Food: Foods containing fats and carbohydrates are generally called ‘energy giving foods’.
  • Growth and Repair: Proteins, essential nutrients in food, are needed for the growth and repair of our body. These foods are called body building foods. 
    • Sources: Some sources are Peas, Gram, Moong, Soybeans, Tur Dal, Beans, Meat, Fish, Paneer and Eggs.
  • Defence against Disease: Vitamins help in protecting our body against diseases. Vitamins also help in keeping our eyes, bones, teeth and gums healthy.
    • Different Types: Vitamins are of different kinds known by different names. 
    • Some of these are Vitamin A, Vitamin C, Vitamin D, Vitamin E and K. 
    • There is also a group of vitamins called Vitamin B-complex.
    • Our body needs all types of vitamins in small quantities.
Vitamins and Minerals Functions Sources
Vitamin A Keeps our skin and eyes healthy. Papaya, Mango, Carrot 
Vitamin B Complex Gives strong muscles.  Rice, wheat, liver
Vitamin C Helps in the fight against diseases. Orange, Guava, Tomato, lemon, Amla, Green Chilli
Vitamin D Keeps our bones and teeth strong. Sunlight, milk, Butter, Fish, Egg, Liver
Vitamin E It is antioxidant, it slows down the process that damages the cell. It also helps to the proper function of many cells. Vegetable oils, cereals, meat, egg, vegetable
Vitamin K Helps in the blood clot, preventing excess bleeding. Leafy greens, meat, egg
Iodine Iodine is needed to make thyroid hormones and these hormones control the body’s metabolism.  Fish, milk, vegetables
Calcium Builds and Keeps bones healthy. Milk, egg
Iron  Iron is part of Haemoglobin and many proteins. Apple, chocolate, leafy vegetables.
Phosphorous Phosphorus works with calcium to build the bones. Fish Milk, green chilli
Dietary fibres or Roughage Not a nutrient but helps in the size of stool and softness. It also helps to decrease the cholesterol level. Whole grain, pulse, fresh fruits, potato
Water Helps to throw out waste via urine and sweat and helps our body to absorb nutrients from food. Drinking water, milk, tea, fruits and vegetables

 

Balancing Act: Navigating the Essentials of a Healthy Diet for Optimal Well-being

Requirement: For the growth and maintenance of good health, our diet should have all the nutrients that our body needs, in the right quantity, not too much of one nor too little of other.

Balance diet= Roughage + water + right quantities of all nutrients

Excess Fat: Too much fat leads to obesity.

Understanding the Impact of Nutrient Deficiency Diseases on Health

Nutrient Deficiency: Diseases that occur due to lack of nutrients over a long period are called deficiency disease.

Example: Lack of protein leads to Stunted growth, swelling face, discoloration of hairs, skin disease, etc.

Prolonged Deficiency: If an individual experiences a prolonged lack of both carbohydrates and proteins in their diet, it can lead to a complete halt in growth. 

Results: This can result in significant emaciation, extreme thinness, and such a severe weakness that mobility may be greatly impaired.

Exploring Deficiency Diseases and the Role of Fortification in Nutritional Wellness

Vitamins and Minerals Deficiency Disease Symptoms
Vitamin A: Loss of Vision Poor vision, loss of vision in dark night
Vitamin B1: Beriberi Weak muscles and little energy to do work. 
Vitamin C:  Scurvy  Bleeding gums, wounds take longer time to heal
Vitamin D: Rickets Bones become soft & bent
Calcium: Bones and teeth decay Weak bones and tooth decay
Iodine: Goitre Glant in the neck, mental disability in children
Iron: Anaemia Weakness

 

Required Fortification: Fortification of food is the addition of key vitamins and minerals to staple foods such as rice, wheat, oil, milk and salt to improve their nutritional content. 

There is a logo for the fortified items as per the standards of FSSAI.
