How much water should we drink every day?

At least 8 cups a day (or 64 fl. oz.) or you weight divide in half. Water is the MOST important nutrient our body needs! If you're thirsty, you're already dehydrated!

What are the six basic essential nutrients

Carbohydrates Fats(lipids) Protein Vitamins Minerals Water

What are the functions of lipids

Carries Vitamins A, D, E, K Provides a reserve store of energy Promotes healthy skin Promotes normal cell growth Acts like a "cushion" to protect organs Acts like a heat regulator and insulator Adds flavor to food Satisfies hunger and helps you feel full longer

What are the functions of water

Carries water soluble vitamins Regulated body temperature through perspiration Carries waste products through and out of the body Prevents dehydration

Why is Cholesterol essential

Cholesterol is ESSENTIAL for many body processes. Cholesterol produces hormones and bile acids (which aid in digestion). Helps with the digestion of fat and production of Vitamin D.

What is fiber. (Give examples)

Complex carbohydrate that helps in the digestion process. Foods high in fiber include: fruits and vegetables (especially the skins or peels), whole grains, beans/legumes, bran cereals

What happens if we have too much water

Drinking too much water or sports drinks during a physical activity causes the condition known as exercise-associated hyponatremia (EAH), in which the kidneys become overwhelmed by the large quantity of liquid it's forced to process. The body's naturally occurring sodium can't keep up with the amount of water, leading to swelling in the cells and in severe cases, death.

Where is cholesterol found in

Eating meat, poultry and fish means you will consume "extra" or unneeded cholesterol. Foods high in cholesterol: Egg Yolks Liver/Organ Meats Some Shellfish

LOWERING FAT & CHOLESTEROL

Exercise Replace solid fats with oils Choose lean cuts of meat Steam, boil or bake foods instead of cooking them in oil or fat Season vegetables with herbs and spices rather than with sauces, butter or margarine Try lemon juice or oil based salad dressing instead of cream based ones Switch to low-fat or fat-free milk Substitute low-fat yogurt in recipes that call for sour cream or mayonnaise Remove skin from poultry before cooking Replace egg yolks with egg whites

Rancid

Fats that have begun to decompose (you can smell it)

Hydration Before, During and After Physical Fitness when to do what

For short duration (less than 60 min) water is a good choice to drink before, during and after exercise. For moderate to high intensity activities (more than 60 min.), sports drinks will help replace carbohydrate loss and electrolyte balance. Drink according to thirst during the day and include fluids with meals. Drink 8-20 oz. of water an hour before exercise. Continue drinking water during exercise, up to 16-24 oz. of fluid per hour (4-6 oz. every 15 min.).

Where is cholesterol found?

Found in animal tissues, but NEVER present in plants.

What ARE the 2 TYPES OF CHOLESTEROL

HDL cholesterol (HAPPY/HEALTHY!) HDL Cholesterol is "High Density Lipoprotein" This is the "good" kind of cholesterol. It moves excess cholesterol from the blood to the liver. 2. LDL Cholesterol ("L" for LOSER!!!) LDL cholesterol is low-density lipoprotein This is the "bad" kind of cholesterol. LDL cholesterol takes the cholesterol from the liver to the blood when it is needed. IT's BAD because too much LDL cholesterol in the bloodstream means BUILDUP in the arteries and increased chance of HEART ATTACK!

how can incomplete proteins become complementary protein.

Incomplete proteins can be combined to create a complementary protein. (Grains combined with any nut, seed or legume.) Plant foods do not, as a rule, have complete proteins, but by eating combinations of plant foods, called "complementary proteins," you can obtain a complete protein. Here is a list of proteins that when eaten together become complete: Grains... with Dairy Nuts/Seeds... with Dairy Nuts/Seeds... with Legumes Dairy... with Nuts/Seeds and Legumes Legumes... with Nuts Legumes... with Grains Legumes... with Seeds Legumes... with Dairy

Where do Incomplete proteins come from Give Examples of incomplete proteins

Incomplete proteins come from plant food sources. Examples of incomplete proteins could be: Grains Beans Nuts/Seeds Rice Wheat

Do incomplete proteins contain all the essential amino acids?

Incomplete proteins do NOT contain all of the essential amino acids.

What can too little protein do

Protein Deficiency -Leads to Kwashiorkor in children happens mostly in impoverished countries where there is a lack of protein rich foods. -In adults it can lead to anemia, Marasmus-the Greek word for "dying away" and infections. - Lead to stunted growth.

What are proteins

Proteins provide 4 calories per gram. , . Is this a good thing? You must eat protein daily It is recommended that we choose 8 oz. of seafood products in the place of some meat and poultry every week.

Provide 9 calories per gram

Where do Saturated fats usually come from

Saturated Fats that usually come from ANIMAL sources, solid at room temperature. Sources: cheese, milk, meat, palm oil, coconut oil.

how much fat do we need?

Teenagers should consume between 25 and 35 percent of their total daily calories from fat. For a 2,000-calorie diet -- the recommended amount for moderately active teenage girls -- 25 to 35 percent of daily calories would equal approximately 55 to 75 grams of fat per day. Moderately active teenage boys need 2,600 calories per day, on average, making their daily fat requirement between 70 and 100 grams.

How many carbs do we need (example)

Teens who consume 45 to 65 percent of their calories from carbs will meet their needs. For example, a teen girl who eats 2,000 calories per day requires 225 to 325 grams of carbs (carbs provide 4 calories per gram), and a teen boy consuming 2,600 calories a day needs about 293 to 423 grams of carbohydrates daily.

What happens if we don't have enough water

The lack of water in our bodies can cause decreased blood pressure, electrolyte imbalances, cardiac arrhythmias and other damages. Remember that water is life.

The six steps of digestion are: 1. ingestion 2. mechanical digestion 3. chemical digestion 4. absorption 5. movement 6. excretion

how may essential amino acids are there.

There are 9 essential amino acids.

What are simple sugars (give examples)

These are broken down and digested very quickly. Examples include: table sugar, fruit, fruit juice, sugary drinks, milk

What are complex Carbs (give examples)

These take longer to digest and provide sustained energy. Examples include: whole grains, beans/legumes, brown rice, pasta

What can too much protein do?

Too much -elevated blood sugar, weight gain, kidney stress.

Where do we get most of our carbs

We get most of our carbs from the grains group. Almost all of our carbohydrates come from plant food sources.

Other sources of water

We should keep in mind that we can substitute part of this amount with fruit and vegetable juices or we can just eat foods that are excellent sources of water. Among them are vegetables, fruit, meat, fish, eggs, soups, ice cream and many others. Fruits and vegetables have the highest water content. For example, watermelon is 92 percent water, grapefruit and strawberries are around 90 percent, celery and radishes contain 95 percent water, cucumbers contain 96 percent, spinach and peppers - 92.
