Junior Cert Home Economics: Healthy Eating
- Why do we eat?
- Most people eat because they feel
hungry or because they like the taste
of food. However, the most important
reason we eat is to stay alive.

- Functions of food
- For the growth and repair of body cells
- To provide heat and energy for the body
- To regulate and protect the body
- For the growth and repair of body cells
- Food choices
- Most foods will keep us
alive, but in order to keep the
body healthy, we must
choose nourishing foods, i.e.
those that will help maintain
good health
- Good food choices
include fruit and veg,
white meat, eggs,
potatoes and fish
- Bad food choices lead to bad health -
many diseases such as cancer, heart
disease, diabetes and dental decay are
associated with an unhealthy diet

- Factors that affect our choice of food
- 1. Senses: Our senses help us to decide
whether we like or dislike a food
- Smell: Cells in the nose pick up the odor of
food. This makes the mouth water and starts
the digestive juices working
- Sight: Food that is well-presented and looks
attractive makes us want to eat it
- Taste: Cells on the tongue, called taste
buds, pick out flavors (sweet, sour, salty,
and bitter)
- Touch: The tongue also senses the texture and
temperature of food. Is it hot, cold, smooth,
lumpy, soft, or crunchy?
- Smell: Cells in the nose pick up the odor of
food. This makes the mouth water and starts
the digestive juices working
- 2. Food value: Is the food
nourishing? Has it a good balance
of nutrients, with the right amount of
kilocalories for the energy needs of
the body?
- 3. Lifestyle: Eating habits are formed at the
home, where children tend to eat the same
thing as their families, whether this is a
nourishing on or not. As children grow older,
outside influences such as friends and
advertising may encourage them to try other
foods
- 4. Culture: The country we live in and the group
or race we belong to influence what we eat. In
Ireland, bread and potatoes are staple foods; in
Italy, people eat lots of pasta. Some religions
have specific rules about what foods may be eaten
(e.g. Hindus do not eat beef). Eating traditions
play a part in celebrations such as weddings,
Christmas, Passover and Shrove Tuesday.
- 5. Cost: What foods can I afford to
buy? Wealthy people may eat more
expensive foods and eat out more
often. Those on a limited budget, e.g.
pensioners, have to settle for cheaper
foods, though these are not
necessarily less nourishing
- 6. Availability: What types of foods are available
in the shops? Today, we have a greater choice of
food than ever before. Improved transport and
technology mean that foods from all over the
world are available all year round. In rural areas
there is often less choice, although some
families may produce some of their own food
- 1. Senses: Our senses help us to decide
whether we like or dislike a food
- Eating patterns today
- Food not only satisfies our hunger, it is also a source of pleasure
and a social activity. At mealtime the family has a chance to sit
down to talk and eat with each other. Regular meals are important,
and three meals a day is the usual pattern - breakfast, lunch and
dinner/supper.
- In recent years there have been
many changes in eating habits.
- Many people lead busier lives,
they have less time for cooking
and for sit-down meals, so they
may not cook or eat together
regularly
- More fast foods (i.e.
processed/convenience
foods, such as McDonald's)
are eaten
- Young people often eat 'on the move' , eating
snacks such as sandwiches or takeaways
- More people eat out in restaurants,
both traditional and ethnic
- There is greater interest in healthy
eating. Organic food (food produced
without the use of artificial chemicals)
and vegetarianism have become popular
- People tend to 'graze' more, i.e. they eat
throughout the whole day, rather than just
three times a day, even though they might
not be hungry.
