What is nutritional chemistry?
This is the science of components of food that are of benefit to the human body.
What is nutritional biochemistry?
This is the science of how foods are assimilated into the human body system and its interactions.
components of foods
- Carbohydrates - composed of carbon, hydrogen and oxygen.
- Proteins - Composed of carbon, hydrogen, oxygen and nitrogen.
- Lipids - Composed of carbon, hydrogen, oxygen. Are not soluble in water.
- Minerals- Macro-minerals -These includes the minerals that are required >1.0 gram per day in the body.Micro-minerals-These includes the minerals that are required <1.0 gram per day in the body.
- Moisture - Its the water.
- Vitamins - Water-soluble vitamins- These are B complexvitamins and C.Fat-soluble vitamins -These are ADE and K.
Unique features of malnutrition
Malnutrition has distinct effects on human health.
Arid areas have a high prevalence for malnutrition.

To calculate the extent of malnutrition, the following equations can be applied with regard to a specific population.
Where x variable is the malnutrition co-efficient and y is the population co-efficient.
