Starches and Sugars present in food.
There are 2 types of carbohydrates, simple and complex.
The main job of carbohydrates is that they give you energy
Foods contain a combination of 3 certain types of fats, all of these having a different effect each on the levels of cholesterol which is found in our blood.

Protein has the job of repair, maintenance and growth and function as building blocks for bones, muscles, cartilage, skin, and blood.

Important for athletes to eat after they finished competing.

Benefits of replacing meats with nuts and seeds:
May reduce the risk of heart disease, but they're high in calories. Eat them in small portions and use them to replace other protein foods, rather than adding them to what you already eat.

For example milk and certain fruits. These are better to have as they will also contain vitamins, Minerals and Fiber, all of which are needed in a healthy diet.
Simple Carbohydrates are the unhealthier option of the two as they contain much more sugar.
Complex Carbohydrates:
Referred to as 'Starches'.
These are the better group of carbohydrates and also
the healthier option
to have, though both are needed in your diet to balance it out, also being more vital to an athletes diet.
They include grains such as wheat, which are used to make foods such as bread, pasta and rice.

Food Inc. Movie Discussion

What did you find interesting about the movie?

Is there anything that you considered changing about your diet after watching this movie?
Food Poisoning
Food may be contaminated
during food processing or food handling.
Food may become contaminated by the
unwashed hands
of an infected food handler. A frequent cause is a food handler who does not wash his or her hands with soap after using the bathroom.
Salmonella may also be found in the
of some animals.
Reptiles, baby chicks and ducklings, and small rodents
such as hamsters are particularly likely to carry Salmonella. You should always wash your hands immediately after handling one of these animals.
Ice from machines
that were not cleaned and sanitized every week.

How do you get salmonella?
What foods are at risk?
Beef, poultry, milk, and eggs
are most often infected with salmonella. But
may also be contaminated. Contaminated foods usually look and smell normal. Ice from restaurants.
Coming into contact with the
, or stool, of humans or animals.
Meat during processing.
If the infected meat is not cooked to 160°F (71°C), the bacteria can survive and infect you when you eat the meat. This is the most common way people in the United States become infected
Lakes, pools, and water supplies.
People can become infected when a contaminated city or town water supply has not been properly treated with chlorine or when people accidentally swallow contaminated water while swimming in a lake, pool, or irrigation canal.
The bacteria can also
spread from one person to another
, usually when an infected person does not wash his or her hands well after a bowel movement.
How do you get E. Coli?
What foods are at risk?
Raw milk or dairy products.
Bacteria can spread from a cow's udders to its milk. Check the labels on dairy products to make sure they contain the word
"pasteurized." This means the food has been heated to destroy bacteria.
Raw fruits and vegetables
, such as lettuce, alfalfa sprouts, or unpasteurized apple cider or other unpasteurized juices that have come in contact with infected animal feces.
How do you get Staphylococcus?
Through contact with food workers who carry the bacteria or through
contaminated milk and cheeses
salt tolerant
and can grow in salty foods like ham.
Staphylococcal toxins are
resistant to heat
and cannot be destroyed by cooking.
Contamination with food made by hand and require no cooking.
Sliced meat, puddings, some pastries and sandwiches.
Food that has been left out
What foods are at highest risk?

Food and emotions-
Stress, Depression, Rewards, and Boredom!

Food and Environment-
Family and friends-
eating habits are shaped as you grow up
Certain diets
Convenience and Cost-
what is close and doesn't cost much
Influences your dietary decisions
What affects your appetite?
the process by which the body takes in and uses food.

Unit of heat that measures the energy used by the body or the amount of energy supplied by the food.

Natural drive to eat

Desire to eat

Substances needed by the body to grow, repair, and supply energy
Unsaturated Fats:
These are generally liquid at room temperature.
They can reduce the risk of Heart Disease.
How much sugar is in soda?
Acidity on tooth enamel
What size should you get?
Trans fats:
Considered by many doctors to be the worst type of fat you can eat
Formed through an industrial process that adds hydrogen to vegetable oil, which causes the oil to become solid at room temperature.
Added to foods to add shelf life
Raises your LDL ("bad") cholesterol and lowers your HDL ("good") cholesterol-- Clogs your arteries and increases chances of heart failure.
Polyunsaturated fats:
2 types: Omega-3 and Omega-6.
These fats provide an essential fatty acid that our bodies need, but can't make.
help decrease the risk of type 2 diabetes.
A high amount of protein can be found in Fleshy foods, such as chicken, fish and turkey.
A lower amount of protein could be found in eggs, grains and soy products.
The majority of sugars in the typical American diet are those added to foods and drinks during processing and preparation.
The U.S. Food and Drug Administration requires all packaged foods and drinks to list the sugar content
per serving.

Manufacturers are not required to list how much of the total sugar in a food or drink is naturally-occurring (i.e. 100% fruit juice) and how much comes in the form of added sweeteners.
There are almost
100 different names
for sugar and sugar alcohols on ingredient lists. Some include:
cane sugar
corn sweetener
corn syrup
fruit juice
high-fructose corn syrup
derived from fruit and vegetables
milk sugar
sugar from grains.
On nutrition facts labels, ingredients are listed in descending order by weight.
Products that list sugar sources near the top of the ingredient list or have several types of added sugar throughout the list have high added sugar content.
Watch their reactions to sugar, and reading the labels!
Irish people taste american snacks
Most common names though?
