Module 02: Basics in Nutrition (Essential Vitamins) Flashcards
These are the types of nutrients that the body entails in large amounts (carbohydrates proteins and fat) in the diet. These are also characterized as calorie yielding nutrients.
Macronutrients
This is characterized as the unit that measures energy. Specifically one of this is the amount of energy it takes to raise the temperature of 1 gram of water by 1 degree Celsius.
Calories
This is delineated as the chief and cheap source of energy. The body cells require a steady and constant supply of energy level in the form of glucose.
Carbohydrates
How many grams of glucose is circulating in the blood?
There is only a total of 10 gm of glucose circulating in the blood or a constant of 70 to 100 mg glucose per 100 mL of blood (normal fasting blood glucose).
Beyond 70 to 100 mg of glucose in the blood is already an indication of diabetes.
How important is glucose in the body?
The glucose must be kept constant and ready for utilization.
Why are carbohydrates known as protein sparers?
If carbohydrate are not supplied, protein will be catabolized to provide heat and energy instead of doing its function.
Why are carbohydrates known as the sole energy source for the brain and nerve tissues?
(A) The brain and the nerve tissue utilize only glucose for energy,
(B) Otherwise, lack of glucose or oxygen needed for oxidation of glucose to release energy.
(may lead to fatigue or nausea)
Why is carbohydrates known as a regulator of intestinal peristalsis and provider of bulk?
Commonly called fiber or roughage in the diet, it serves as a broom and regulates peristalsis movement.
What are the sources of simple sugars?
(A) Table sugar (white, washed or brown) and syrups
(B) Jams and jellies
(C) Preserves and candies
(D) Softdrinks
(Glucose is converted to adenosine triphosphate or ATP in the Krebs cycle)
What are the sources of complex carbohydrates?
(1) Whole grains (cereals)
(2) Root crops
(3) Fruits and vegetables
This is known as the process that transforms paddy rice into food consumable by humans.
Milling
Based on the anatomy of a rice grain, this is known as the fibrous indigestible shell.
Hull
Based on the anatomy of a rice grain, this is characterized as the outer layer of the dehulled rice kernel.
Bran
Based on the anatomy of a rice grain, this is characterized as the large interior, containing most nutrients (fiber).
Endosperm
Based on the anatomy of a rice grain, this is characterized as the embryo of the rice kernel, containing most of the oil.
Germ
These types of fibers are characterized to dissolve in water and slow down digestion to give you that full feeling.
Soluble fibers
These types of fibers are characterized to add bulk to diet and help with constipation and also has that laxative benefit.
Insoluble fibers
What are examples of soluble fibers?
Oatmeals lentils apples oranges nuts flaxseeds beans dried peas cucumbers celery carrots pectin
What are examples of insoluble fibers?
Barley couscous brown rice zucchini broccoli cabbage green beans dark leafy vegetables and root vegetable skins.
Why does soluble fibers give you a full feeling?
Soluble fiber draws water into your gut, which softens your stools and supports regular bowel movements. It helps you feel fuller and reduces constipation, and may also lower your cholesterol and blood sugar levels.
(Helps prevent cardiovascular diseases)
This deficiency in carbohydrates is characterized as the deficiency of proteins and calories. It is most common in infants under 1 year of age.
Marasmus
What are the symptoms of marasmus?
(1) Subcutaneous fat is not preserved.
(2) Oedema is absent.
(3) No fatty liver and ribs become very prominent.
(4) Alert and irritable
(5) Severe muscle wasting and voracious feeder.
What do patients suffering from marasmus need?
The person suffering from marasmus needs adequate amount of protein fats and carbohydrates.
What are the functions of proteins?
Build, repair and maintain tissues. All living cells are built and repaired by protein.
How will growth occur in the context of proteins?
For growth to occur, essential amino acids needed for specific protein molecule must be available in proper amounts.
These are entailed for growth and development and maintenance of life considered of high biological value.
Essential or complete proteins
Why is protein known as the regulator of body processes?
Because it regulates water balance and acid base balance
Why is protein characterized as the supplier of energy?
1 gm of Protein is four calories, though. Protein should not be primarily used as a source of energy.
What are the sources of proteins?
(A) Meats (beef pork chicken lamb and carabeef)
(B) Glandular organs
(C) Milk and milk products
(D) Seafoods and eggs
What are the vegetable sources of proteins?
(A) Soybean and by products (taho tofu tokwa)
(B) Legumes and beans
(C) Nuts sitaw and patani
What are the different types of protein substitutes?
(A) Gluten (from wheat and barley that adds elasticity quality for foods)
(B) Textured Vegetable Portein (TVP) : defatted soy product
(c) Mycoprotein
This deficiency develops in children whose diets are deficient of protein. This occurs in children between 6 months and 3 years of age.
Kwashiokor
What are the symptoms of Kwashiokor?
(1) Subcutaneous fat is preserved.
(2) Oedema is present
(3) Enlarged fatty liver
(4) Ribs are not very prominent
(5) Lethargic
(6) Muscle wasting is mild or absent along with a poor appetite
What do patients with Kwashiokor need?
The person suffering from Kwashiokor needs adequate amounts of proteins (any extra protein in the diet adequate in carbohydrate and fats will yield additional calories and can be stored as body fat).
This is known as the concentrated source of energy.
Fats (1 gm of fat is equal to 9 calories)
Explain the storage form of energy in tissues within the body.
Storage form of energy adipose tissue is the largest storage of potential energy-
subcutaneous tissues( 50% ), surrounding organs (45%) & intramuscular tissues (5%)
When can fat storage be delineated as excessive within the human body?
When fat storage is excessive ( over 20% overweight), this can result to obesity.
What essential fatty acids does fat supply the human body?
(A) Arachidonic
(B) Linoleic
(C) Linoleic (PUFA)
Arachidonic acid and linoleic acid can be synthesized in the body from linoleic acid (constitutes about 30% of the human diet)
Why are fats characterized as the carrier of FAT soluble vitamins (ADEK)?
Carrier of FAT soluble Vitamins (ADEK) these vitamins need fat to keep them in solution and facilitate reactions in food and in the body. (transport carrier)
What are the animal sources of fats?
(1) All animal meats
(2) Milk and milk products
(3) Seafoods and shellfish
(4) Source of saturated fats and cholesterol, sausages, bacon and lard
(They supply more energy (calories) than carbohydrates)
What are the vegetable sources of fats?
(1) Avocado and avocado oil
(2) Olive oil and peanut oil
(3) Corn oil and palm oil
(If used to replaced saturated fats: also helps in decreasing cholesterol)
This kind of fat is utilized to replace saturated fats and also decreases the total cholesterol, triglycerides and LDL. It also increases high density lipoproteins (HDL).
Omega 3 fat
What are the sources of omega 3 fat?
(A) Salmon mackerel and tuna
(B) Canola and flaxseeds
(C) soy foods
(D) Walnuts
This kind of fat is utilized to increase total cholesterol and low density lipoproteins.
Transfat
What are the sources of transfat?
(A) Margarine
(B) Cakes and cookies
(C) Doughnuts and chips
(D) Shortening (Lard)
These type of nutrients are characterized to be only entailed by the body in small amounts.
micronutrients
What are the two groups of vitamins?
(A) Fat soluble: ADEK
(B) Water soluble: Thiamine riboflavin nicotinic acid Pyridoxine Cobalamin Pantothenic Acid Folic Acid Choline Biotin Vitamin C
What are the general properties and stability of fat soluble vitamins?
(A) They have precursors or provitamins.
(B) Deficiencies are slow to develop because they can be stored in the body.
(C) Not needed daily from food sources.
(D) generally stable especially ordinary cooking methods.
What are the general properties and stability of water soluble vitamins?
(A) Should be supplied in the diet everyday (because they are excreted)
(B) Not stored significantly in the body and excreted in the urine
(C) Deficiency symptoms develop relatively fast
(D) Most likely to be destroyed in ordinary cooking
This vitamin is known to maintain integrity of epithelial tissues especially mucus lining (lining the respiratory tract, digestive tract, eyes and skin).
Vitamin A
