Provides energy
Basic unit is glucose Primary energy source for the brain
What are the functions of carbohydrates
|
Found in animals only
Where is cholesterol found?
|
0.8g/kg/day
What is the RDA for protein
|
Cardio, strength, flexibility
What are the 3 types of physical activities recommended
|
LDL transport cholesterol and triglycerides from the liver to the tissues. HDL scavenge excess cholesterol and phospholipids from the tissues and return them to the liver.
What is the difference between LDL and HDL cholesterol
|
World Health Organization says no more than 10% of total calories to come from added sugars, including sodas/sugar sweetened beverages.
What are the recommendations around added sugars, like high fructose corn syrup and fruit juice concentrate.
Note that the uptrend in sugar consumption can be attributed to food manufacturers. |
It provides insulation to the body.
It is an essential constituent of cell membranes. It is a storage form of energy. It contributes to improved skin complexion.
What are the function of fats
|
Primary function is build proteins needed by the body. Basic building blocks are amino acids (20 different). Secondary source of energy (when glucose is not available)
What is proteins function
|
Specify nutrient needs that best support the health of people in the United States. The Recommended Dietary Allowances are the foundation of these. And the Tolerable Upper Limits are limits set to protect consumers against excessive intakes that can pose hazards.
What are the Dietary Reference Intakes
|
producing biotin.
protecting people from infection. producing vitamin K. breaking down fiber
What are the functions of bacteria in the gut
|
Soluble: binding cholesterol and carrying it out of the body with the feces.
Insoluble fiber: It adds bulk to the stool and appears to help food pass more quickly through the stomach and intestines. Sources: whole grains, fruits and vegetables DRI is 25-35g/day
What are the functions and sources of soluble and insoluble fiber?
|
Excessive intake of protein, carbs, and fat all contribute to this unlimited storage, but fat is the easiest to contribute.
Explain the storage of fat
|
Essential must be supplied by the diet (9 essential) and non essential are made within the body (11 non-essential)
What are essential and non essential amino acids
|
Fat 9 calories per gram
Carbs 4 calories per gram Protein 4 calories per gram Vitamins and minerals 0 calories per gram
What are calories per gram of fat, protein, carbohydrates, vitamins and minerals
|
Release of digestive enzymes into the small intestines
Releases bicarbonate which makes the acidic chyme more alkaline
What are the functions of the Pancreas (2)
|
When glucose goes too low, glucagon promotes breakdown of liver glycogen
What is the management of blood sugar
|
Ex. linoleic acid (omega 6) & linolenic acid (omega 3). Linoleic is primarily found in vegetable oils. Linolenic is primarily cold water fatty fish, walnuts, algae.
What are essential fatty acids and two examples
|
Positive balance is during growth or pregnancy. Negative balance occurs during critical illness such as a burn.
What is positive and negative nitrogen balance
|
Fat 20-35%, carbs 45-65%, protein 10-35%
What are the Acceptable Macronutrient Distribution Ranges of fat, protein, and carbohydrates
|
3 parts: Duodenum. Jejunum, ileum
Villi – finger like projections to aid absorption Microvilli – microscopic hairs covering the surface of each cell lining
What is the anatomy of the small intestines
Note: Small intestines is the primary site of absorption |
Maltitol, Xylitol, Erythritol, Sorbitol
What is an example of a sugar alcohol
|
Replacing saturated and trans-fats with unsaturated fats. Eat more plant based fats, ie peanut butter.
What is one recommendation for decreasing saturated fats
|
Intake of iron and zinc and calcium may be too low. And B12 – since its only found naturally in animal-derived products.
What are some nutrient concerns for vegetarians
