The Eco system provides biodiversity and it is necessary for the variety of life on earth. Our Eco system not only gives us perfect living environment conditions but enables us to have fresh fruits, vegetables, meat, poultry, marine food, and much, much more. We cant be thankful enough for this amazing power of nature itself. Through Ecosystem we get multiple sources of having a healthy diet which is a must for our physical and mental growth and health.
A healthy diet contains a balanced mix of different foods that together provide all essential nutrients. To define malnutrition we can say that it is the lack of a balanced diet for a person. Such as:- Too few nutrients, too many nutrients, or an imbalance of nutrients, too many carbohydrates, for instance, and not enough fruits and vegetables. All of such conditions can lead to malnutrition.
Undernutrition is a form of malnutrition. Undernutrition is associated with hunger. It happens when the body does not get enough food to meet its needs. Many diseases and even death can be caused by a lack of food. Death due to lack of food is called starvation.
Cereal grains are the Edible seeds of certain grasses. People have grown them since the beginning of Civilizations. The most commonly grown grains are Wheat, Rice, and Corn.
Worldwide, cereal grains are the most important food staples. They are eaten almost daily by large populations. Throughout the world, more wheat is planted than any other grain product.
On number two, rice is planted all over the world. Whereas sorghum and millet are other grains commonly used as livestock feeds. Corn, barley, oats, and ray are often used in soups and other foods. Oats and rye were domesticated much later than other grains. Oats are used mainly as livestock feed, but also go into oatmeal and other breakfast cereals.
The term fruit means the part of a plant that contains seeds. According to this definition, fruits include most nuts, as well as vegetables, such as cucumbers and tomatoes. To most of us, though, “fruit” is defined as the soft, edible, seed-bearing part of a perennial plant. A perennial is a plant that lives for more than one growing season. Fresh fruits are rich in carbohydrates, vitamins, minerals, and fiber.
Different fruits grow in different climates, and may not grow well in climates that are too cold, hot, dry, or wet. Based on the kind of climate in which they grow, fruits can be classified into different groups:-
- Temperate fruits
- Subtropical fruits
- Tropical fruits
Temperate fruits are those adapted to temperate zone climates in the middle latitudes. Some examples of these include apple, pear, peach, plum, grape, and strawberry.
Tropical fruits require a hot climate to grow. Tropical fruits, such as bananas, mangoes, and papayas, grow in hot, humid areas.
Subtropical fruits thrive where temperatures are mostly warm year-round. Citrus fruits, such as lemons, oranges, grapefruits, dates, pomegranates, and some types of avocados, are subtropical fruits.
Vegetables are the edible parts of herbaceous plants. Herbaceous plants, sometimes just called herbs, have stems that are softer and less woody than those of trees and shrubs. Vegetables are good sources of fiber, minerals, and vitamins. Most vegetables are annuals, living for only one growing season. Vegetables can be roots, leaves, stems, seeds, or bulbs. Pulses contain high amounts of protein and other minerals and vitamins.
The term “Meat” usually refers to the edible flesh of mammals. Meat is a high-protein food and is rich in other nutrients, as well. Meat from very young cattle, or calves, is called Veal. Whereas lamb is meat from sheep less than a year old.
“Poultry” is a term for domesticated birds that are raised for meat and eggs. Chickens are an important food source for most of the world’s population.
Fish are also one of the most popular meats worldwide. An increasing amount of fish comes from fish farms, where fish are raised commercially. The cultivation of fish and shellfish is called aquaculture.
Eggs are a source of proteins, fats, minerals, and vitamins. Boiled, fried, scrambled, or deviled, chicken eggs are popular around the world.
Agricultural technology is improving with better varieties of seeds, better fast transportation, communications systems, and storage facilities. These are all adding to improved quality food production, packaging, storage, and distribution, bringing more good for farmers, the whole supply chain, and companies.
