CRUNCH!

12. Influences on Food Preference
Cultural Heritage: How your ancestors prepared food; based on what was/is available
Ex: Thai food uses a lot peanuts, rice, and curry powder – because those foods grow well in Thailand & are available in abundance

13. Influences cont.
Levels of Hunger: If hunger level is high, the human sensory level of food is lessened and there is more focus on the issue of survival
Tip: Never go to the grocery store while hungry!
Media/Advertising: National Brands highly advertised might be popular but are not actually better than the store brand. Our brain may subconsciously identify a well-known brand as better, affecting our perception
Brand Loyalty: Where you buy and what you buy because you know what to expect; you “trust” it

5 foods you like and 5 foods you dislike
for each food you like, give a reason using at least 2 senses
For each food you don’t, give a reason using at least 1 sense
“Likes” Example
I like almonds because they are crunchy (mouth feel & sound), and have a light hint of sweetness (taste)
