DIET

Diet is the total amount of food consumed by a person. Nutritious food contains all the essential nutrients proteins, fats, carbohydrates, vitamins and minerals. A balanced diet should contain all these in the correct proportions and sufficient quantity. The word  diet implies a particular intake of food for health or weight management reasons. Nutrition is the provision of materials to an organism to support its life. Food is a thing which, when eaten and digested, can be used by the body to provide energy, or substances that help in the body building and repair or in the preservation of health.
    Foods may be grouped into types according to whether they are solid or liquid. Solid food are potatoes, rice, beans and liquid foods are milk, fruit juices.
    Foods can also be grouped into classes based on the chemical composition of the food and the nutrients present in the food. Foods are grouped into six classes, namely carbohydrate, protein, fats, vitamins, minerals and water. Carbohydrates are composed of carbon, hydrogen and oxygen. Carbohydrate are energy giving food. E.g garri, yam e.t.c. Protein comprises carbon, hydrogen, oxygen and nitrogen atoms. They may also contain sulphur and phosphorus. Protein are used in body building and growth and repair of worn out cells.E.g meat fish. Fats and oils are composed of carbon, hydrogen and oxygen atoms. Fats are solid at room temperature while oils are liquid at room temperature, but their chemical compositions are similar. They are energy giving foods. E.g are animal fats, Palm oil, margarine. Vitamin are required by in small amounts. E.g are vitamins A,B,C,D,E and K. When present the body is healthy. When each vitamin is absent, the body suffers from a specific disease, unique to the absence of that vitamin.The diseases arise when vitamins are absent these are called vitamin deficiency diseases.

Natural soil

 Natural soils are influenced by rainfall and temperature,heavy rain causes the soil to become leached. High temperatures increase the rate of decomposition of organic matter in the soil, thereby lowering its humus content. Thus, climatic conditions tend to produce poor soils in the tropics and rich soils in the temperate regions. Besides climate and vegetation, the parent rock material also contributes to the quality of the soil. For example volcanic rocks tend to produce fertile soils.    Laterite, a red soil which is a product of leaching, is commonly found in the tropics. It is composed mainly of iron and aluminium compounds,and poor in humus and essential plant nutrients, such as phosphorus, nitrogen and potassium. The black and brown soil of the temperate grasslands are the world's richest soils, with a high mineral and humus content. The light coloured desert soils tend to be very rich in minerals but have a low humus content.    Mainly the soils ar...

Rock Formation

A rock may be defined as a hard compact mass made up of cluster of primary or secondary minerals. The primary minerals are those that are as they were made in nature. Some of them are Quartz, Olivine, Pyroxene, Hornblende, Biotite, Muscovite and feldspar. On the other hand, secondary minerals consists of particles worn out from original minerals which have combined with other elements. They exist in form of: (i) Oxide such as those of magnesium, Iron and Aluminum. (ii) Sulphates and carbonates of Iron, Magnesium and Calcium. (iii) Clay minerals such as the silicate clays and the hydrous Oxide.   TYPES OF ROCKS (i) Igneous rock (ii) sedimentary rock (iii) Metamorphic rock. Based on their chemical composition, we have basic and acidic rocks. Granite is a very good example of an acid rock. PROCESSES OF ROCK FORMATION IGNEOUS ROCK :This is formed through the process of cooling and hardening of the molten magma. This molten magna is confined deep down below the earth crust und...

Physical fitness

Physical fitness is the ability to function effectively throughout your workday, perform your usual other activities and still have enough energy left over to handle any extra stresses or emergencies which may arise.      There are 5 Components of Physical Fitness The 5 components of physical fitness are often used in our school systems, health clubs and fitness centers to gauge how good a shape we are truly in. The 5 components that make up total fitness are: Cardiovascular Endurance Muscular Strength Muscular endurance Flexibility Body Composition Total fitness can be defined by how well the body performs in each one of the components of physical fitness as a whole. It is not enough to be able to bench press your body weight. You also need to determine how well you can handle running a mile etc. A closer look at the individual components: Cardiovascular endurance is the ability of the heart and lungs to work together to provide the needed oxygen and fuel t...
