FACTORS

AFFECTING

FOOD CHOICE

AND

REGULATION


• Biological determinants such as hunger, appetite, and taste

• Economic determinants such as cost, income, availability

• Physical determinants such as access, education, skills (e.g. cooking) and

time

• Social determinants such as culture, family, peers and meal patterns

• Psychological determinants such as mood, stress and guilt

• Attitudes, beliefs and knowledge about food

Major determinants of food choice [1]


*Hunger and satiety

*Palatability and taste

Biological determinants of food choice


Our physiological needs provide the basic determinants of food choice.

Humans need energy and nutrients in order to survive and will respond to the

feelings of hunger and satiety. The central nervous system is involved in

controlling the balance between hunger, appetite stimulation and food intake.

Hunger and satiety


The macro-nutrients; carbohydrates, proteins and fats generate satiety signals

of varying strength. Protein has been found to be the most satiating.

Hunger and satiety


The energy density of diets has been shown to exert potent effects on satiety;

low energy density diets generate greater satiety than high energy density

diets. The high energy density of high-fat and/or high-sugar foods can also

lead to ‘passive overconsumption’→ without intention

Hunger and satiety


An important satiety signal may be the volume of food or portion size

consumed.

Hunger and satiety


Palatability is proportional to the pleasure someone

experiences when eating a particular food. It is dependent on

the sensory properties of the food such as taste, smell, texture

and appearance.

High fat-sugar-salt → hyperpalatable foods→food addiction

It is not surprising then that food is not only accepted as a

source of nourishment but is often consumed for the pleasure

it gives.

Palatability and taste


From an early age, taste and familiarity influence behaviour towards food.

A liking for sweetness and a dislike for bitterness are considered innate

human traits.

Taste preferences and food aversions develop through experiences and are

influenced by our attitudes, beliefs and expectations.

Palatability and taste

Badly shaped brownies!


Low-income groups have a greater tendency to consume unbalanced diets

and in particular have low intakes of fruit and vegetables. However, access to

more money does not automatically equate to a better quality diet.

Geography, climate, nutrition policies…

Cost and accessibility


Studies indicate that the level of education can influence dietary behaviour.

accurate and consistent messages through various media, on food

packages and of course via health professionals!

Education and knowledge


Cultural influences

Family

Environment → school/work

TV

Social media

Social determinants of food choice


Skipping meals

Snacking habits

Meal patterns


Stress→short and long term effects

Mood → The ambivalent relationship with food – wanting to enjoy it but

conscious of weight gain is a struggle experienced by many

Psychological factors

Recognizing nicotines appetite decreasing effect and starting to abuse it for skipping a

meal or weight loss
