Nutrition counseling is a personalized, one-on-one or group interaction that involves assessing nutritional needs and providing specific guidance to improve dietary behaviors.
Nutrition education is the process of providing general knowledge and motivation about healthy eating to individuals or communities for better nutrition and health outcomes.
Both approaches are vital tools in public health and community health nursing.
“Mother’s milk is best – no water or top feed till 6 months.”
“Give home-cooked, soft foods 5–6 times a day using family food.”
“Eat healthy to study and play well!”
“Eat iron-rich foods daily—be strong, be sharp!”
“A healthy mother gives birth to a healthy baby.”
“Eat right today, stay fit tomorrow.”
“Eat light, eat right, stay active.”

Food Safety refers to handling, preparing, and storing food in a way that prevents foodborne illness and contamination.
It includes all measures that ensure food is safe for consumption, from farm to fork.
🔹 WHO Definition:
“Food safety is the absence — or acceptable and safe levels — of hazards in food that may harm the health of consumers.”
Food safety involves 3 main types of hazards:
– Bacteria (e.g., Salmonella, E. coli), viruses (e.g., Norovirus), parasites.
– Causes: Improper cooking, poor hygiene, contaminated water.
– Pesticides, food additives, heavy metals, cleaning agents.
– Causes: Overuse of chemicals, poor storage, contamination.
– Foreign bodies like glass, stones, metal, plastic.
– Causes: Poor manufacturing or packaging.
| Category | Examples |
|---|---|
| Food sourcing | Locally grown, free from pesticide contamination |
| Food storage | Correct temperature, away from chemicals |
