Q

What are Ketones?

A

Ketones are chemicals made in your liver. You produce them when you don’t have enough insulin in your body to turn sugar (or glucose) into energy. You need another source, so your body uses fat instead. Your liver turns this fat into ketones, a type of acid, and sends them into your bloodstream.

Fiber - bonds are unbreakable, therefore are undigested.
Glycogen - can be digested rapidly

26
Q

Where does all ingested carbohydrate eventually end up?

A

all ingested carbohydrate eventually end up in the liver as glucose

27
Q

What happens to ingested carbohydrates if organs are fueled properly and glycogen stores are full?

A

The liver takes the excess glucose molecules, converts them to fatty acids, and stores them as triglycerides in adipose tissue.

28
Q

What are triglycerides?

A

Lipids contain the following three elements: carbon, hydrogen, and oxygen. A triglyceride contains three fatty acids, which are composed of a long chain of carbon and hydrogen atoms bound together, connected to a small carbon-containing molecule called glycerol.

29
Q

How are lipids classified?

A

Lipids are classified as fats and oils. Fats are usually solid at room temperature, while oils are liquids. Fats can further be classified by their degree of saturation: Saturated, Unsaturated, Monounsaturated, and Polyunsaturated (Omega-3 & Omega-6).

30
Q

How are polyunsaturated fats classified?

A

Polyunsaturated fatty acids can be further categorized as either omega-3 or omega-6 - both are essential, which means they cannot be synthesized by the human body and need to be consumed in the diet.

31
Q

Where is the primary site of lipid digestion?

A

The primary site of lipid digestion is within the small intestine. Lipids are best digested with the help of a compound called bile, which is an emulsifying compound made by the liver and stored in the gallbladder.

32
Q

How are proteins classified?

A

Proteins contain the following elements: carbon, hydrogen, oxygen, and nitrogen. The smallest unit of a protein is called an amino acid. Two amino acids joined together form a dipeptide; three form a tripeptide; and many joined together form a polypeptide.

33
Q

What is the smallest unit of a protein is called?

A

The smallest unit of a protein is called an amino acid. Two amino acids joined together form a dipeptide; three form a tripeptide; and many joined together form a polypeptide.

34
Q

How many different amino acids are in the human body?

A

There are 20 different amino acids in the human body. There are 9 essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine - these cannot be produced by the body. The 11 non-essential amino acids: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine. Complete proteins contain all of the essential amino acids in one product.

35
Q

A

There are 9 essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine - these cannot be produced by the body.

36
Q

How many non-essential amino acids are there?

A

The 11 non-essential amino acids: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.

37
Q

What is a complete protein?

A

Complete proteins contain all of the essential amino acids in one product.

38
Q

Where is the primary site of protein digestion?

A

Protein digestion begins in the stomach with the aid of pepsin. However, the primary site of protein digestion is the small intestine, where enzymes called proteases digest the proteins into smaller units for absorption.

39
Q

What is a catabolic state?

A

A catabolic state means that your body is breaking down tissue. Whenever you workout, whether it’s cardio or weightlifting, you’re causing tiny tears in your muscle. The longer and harder you workout, the more damage you’ll cause to your muscle tissue.

40
Q

What is an anabolic state?

A

An anabolic state means that your body is building or repairing tissue. When you rest, your body goes into damaged muscle tissue and begins repairing it. It’s during rest, not exercise that you actually put on all of your size.

41
Q

What are fat-soluble vitamins?

A

Vitamins A, D, E, and K require dietary fat for absorption and are stored in adipose tissue.

42
Q

What are water-soluble vitamins?

A

Water-soluble vitamins are not stored in the body, are depleted more rapidly, and therefore, need to be consumed regularly.

43
Q

What are common sources of Vitamin A (beta-carotene)?

A

Egg yolk, cod liver oil, carrot, papaya, mango, broccoli, spinach, and most dark green, leafy vegetables.

44
Q

What are common sources of Vitamin C?

A

Citrus fruits, peppers, strawberries, kiwi, broccoli, brussels sprouts, cauliflower, spinach, cabbage, turnip greens, and other leafy greens, sweet and white potatoes, tomatoes and winter squash.

45
Q

What are common sources for Vitamin E?

A

Avocados, olive oil, nuts (almonds and hazelnuts), seeds (sunflower seeds), green leafy vegetables (spinach and broccoli)

46
Q

What are common sources of Copper?

A

Salmon, organ meats (kidneys, liver), dark leafy greens, cocoa, black pepper.

47
Q

What are common sources of Selenium?

A

Brazil nuts, yellowfin tuna, mushrooms, pork, beef, turkey, chicken, and eggs

48
Q

What are the primary functions of water in the body?

A

Approximately 60% of the body is made of water. Water is essential to survival. Water aids in transportation, as a component of blood and urine; removal of waste products; protection, serving as a lubricant, cleanser, and cushion; involvement in many metabolic reactions; temperature regulation.

49
Q

What is the average body water loss?

A

The average body water loss is approximately 2.75 L per day. Water loss occurs in the form of sweat and urine at about 1-2 L per day. An additional liter can be lost via evaporation in expired breath and from skin.

50
Q

Vitamin D

A

Vitamin D is central to the body’s immune system. Low levels of vitamin D are associated with increased risk and prevalence of infections in multiple studies.

51
Q

Selenium

A

Selenium is an essential mineral that is a cofactor in glutathione production. It is also important for hormonal balance, antioxidant defense redox signaling, and redox homeostasis (balancing the oxidative stress in the body).

Viral infections frequently produce a higher number of reactive oxygen species (ROS). When overwhelming the antioxidant defense system, the excess production of ROS induces oxidative stress. ROS, in turn, can enhance viral replication. The viral infection then increases the need for certain micronutrients such as selenium in the antioxidant defense.

52
Q

Vitamin C

A

Vitamin C is an antioxidant, and helps to recycle oxidized glutathione back into active glutathione.

Based on a large meta-analysis, regular intake of vitamin C has not been shown to prevent colds but it can shorten the duration of colds (by 8 % in adults and 14 % in children) with slightly less severe symptoms.

Mega-dosing vitamin C may be helpful in treating the flu right after the appearance of flu symptoms with hourly doses of 1000 mg of Vitamin C for the first 6 hours and then 3 times daily thereafter.

53
Q

Zinc

A

Zinc is required for the function of more than 300 enzymes and more than 1000 transcription factors (proteins that regulate the function of genes). Zinc also plays an important role as a structural agent of proteins and cell membranes preventing oxidative stress.

Zinc is important for hormone production and immunity. It is also known for fighting against infections. Low zinc status in the body can cause gastrointestinal problems and increase the risk of pneumonia. Be reasonable with supplementation: very high zinc supplementation can cause toxicity and stomach pain.

54
Q

Vitamin B3 (niacin)

A

Vitamin B3, or niacin, supplementation increases NAD+ biosynthesis.

55
Q

Ubiquinone (coenzyme Q10)

A

Ubiquinone (coenzyme Q10) acts as a contributor to the electron transport chain. It is a fat-soluble compound that helps to generate ATP (adenosine triphosphate).

Low cellular ubiquinone levels may be a predisposing factor for various illnesses due to insufficient aerobic energy production in the cells. With low energy production, the body will not be able to fight the intruders.

Ubiquinone reduces oxidative stress and preserves macrophages in the immune system.
