Planning meals and why food is cooked Flashcards
what do people with lactose intolerance need to avoid
-food that contains a sugar called lactose
-lactose is found in milk
name what people with lactose intolerance should substitute these with
-normal milk
-dairy products
-soya/almond milk

-avoid nuts and processed foods that contain traces of them
-allergic reactions can be fatal so its important to check labels carefully
subsititutes
-alternative flours e.g, rice flours
vegetarians
-do not eat meat
how diet affects health for people with obesity
State 5different reasons for why food is cooked
-to make it safe to eat
-to improve shelf life
-to develop flavours
-improve texture
-give variety in the diet
Whys it important foods cooked to Develop flavours
-chemical reactions take place during cooking that change the flavour of food
-e.g caramelisation occurs when onions are cooked, making them taste sweeter
-roasting meat and beg creates more intense flavours
Why are foods cooked in a variety of ways
-to create variety in the diet
-when wanting beef, you can satisfy it with grilled steak, roast beef, beef stew,
Whys it important to improve texture
-makes it easier for us to chew, swallow and digest
-foods become softer, as starch molecules soften e.g rice and pasta
-meats become more tender as solid fats in the food melt and proteins soften
-makes it more pleasant to eat, e.g roast potatoes have a soft centre and crispy outside
Name 3 ways heats transferred
-conduction
-convection
-radiation
what is conduction
the transfer of heat energy through the vibration of particles
explain the process of conduction
-heat energy causes particles in the pan to vibrate more and gain heat energy
-when particles collide with nearby particles, they pass some extra heat energy on them
what is convection
the transfer of heat energy through gases or liquids
what is radiation
process where heat energy is transferred in the form of electromagnetic waves
