Theme 2: Food and Nutrition
1. Introduction
It is quite common to confuse the concepts of nutrition and food, yet they are not synonymous. Food consumption is a voluntary process, while nutrition is an involuntary process that occurs as a result of the former.

1. Health and Disease
1.1. Introduction
Defining the concept of health is not easy, yet it is universally understood. Its meaning has changed significantly throughout history, from prehistoric humans with a magic-religious view of life to the scientific and rational humans of modern times. It has been widely believed that health is the absence of disease. However, this is a vague concept, as many situations exist where it’s impossible to establish a clear boundary between

Vegetables: Nutritional Powerhouses
Vegetables are edible plants that can be enjoyed raw or cooked. Their basic structural unit is the plant cell, and they are excellent sources of fiber and essential phytochemicals.
Popular Vegetables Grown Worldwide:
- Tomato
- Cauliflower
- Onion
- Cucumber
Parts of Vegetables:
Roots:
The plant’s body responsible for nutrition and sugar storage (e.g., radish, turnip, beet, carrot).
Underground Stems:
Thick underground stems that store starch (e.g., potato, sweet potato, yam, cassava)
