Q

WHEY’ Protein

A

 Whey is the ‘liquid’ portion of milk when it separates from
the curds in processing
 Whey contains proteins, fats,
carbs, vitamins & minerals
 Pushing the liquid portion of milk through a filter separates
the whey protein
 Because it is a strong source of amino acids, it’s a
very popular exercise nutrition supplement

Q

whey continued

A

This by-product is then dried and turned to powder
 20% of protein in milk comes from ‘whey’
 Water soluble and is ‘fast digesting’… rapid source of
amino acids to muscles
Whey has all 9 essential amino acids

Q

‘3 Types’ of WHEY Protein
WPC (Whey Protein Concentrate)

A

 Whey consists of Protein, Fat, & Carbs (in the form of lactose)
 Whey can vary from 30% - 80% Protein by volume
 Whey Concentrate is the least ‘processed’ form
 Contains more ‘lactose’ than other forms…
so not great if you are lactose intolerant
 Cheaper than whey ‘isolate’
or ‘hydrolysate’

Q

‘3 Types’ of WHEY Protein
WPI (Whey Protein Isolate) ***

A

More protein per serving!
 Typically 90% protein per scoop
 It’s further processed to remove lactose and fat
 It’s the best choice for lactose intolerant
 Most popular & effective
form ‘post-exercis

Q

‘3 Types’ of WHEY Protein
WPH (Whey Protein Hydrolysate)

A

Partially broken down by ‘hydrolysis’ (exposing the protein to heat,
acid or enzymes). Breaks apart the bonds linking amino acids
 This makes it taste more bitter, but also allows it to
absorb more rapidly than a concentrate or isolate
 Whey Hydrolysate improves digestibility (i.e. used in baby formulas)
 Concentrates and isolates are already fast-digesting, so a hydrolysate,
which digests ‘minimally’ faster, may not be worth the taste trade-off and
extra cost for the small benefit

Q

Benefits of ‘WHEY’ Protein

A

Improved Protein Synthesis
 Protein production is enhanced
 Leads to better muscle tissue building & repair
2. Promotes Fat Burning
3. Anti-Cancer Properties
4. Lowers LDL (bad cholesterol)
5. Lowers Blood Pressure

Q

negative of ‘whey’ protein…

A

the release of Amino
Acids is short-lived. You must ingest smaller, repeated
amounts throughout the day.

Q

‘CASEIN’ Protein

A

80% of protein in milk is ‘CASEIN’
Casein is found in the ‘curd’ part of milk
 A cup (250ml) of milk containing 8 grams of protein would
contain 6 grams of casein. Cottage cheese has even more!
 Results in a slower-release protein with a lower insulin
response (i.e. lower influx of sugar to bloodstream)
 Slower digesting (stays in stomach longer) and releases
amino acids more slowly throughout the night (for hours)
 Best taken in the late evening or bedtime
 i.e. Casein powder, Greek Yogurt, or Cottage cheese

Q

Best ‘Protein’ Strategy?

A

 Consume approximately 2 grams PRO/kg each day
 We know that it’s best to ingest protein in smaller
dosages (10-20 grams) multiple times throughout
the day (maximum 0.5 grams/kg at once)
 Tale 20 grams before workouts and 20 grams post
workout for optimal amino acid concentration
(muscle fiber building & repair)
 Take whey during the day and casein before bed

Q

Best Combination Strategy for Protein?

A

Eat meat, dairy, plant sources at Mealtime (4-5 X per day)
 Take Whey Pre & Post Exercise (Isolate is best post-exercise)
 Consume protein in ‘food’ form (meat, dairy, plant protein)
30-90 minutes after a ‘whey’ protein supplement (because
the release of amino acids is short-lived)
 Take Casein before bed, in combination with a food
containing lipids (i.e. Greek Yogurt… higher pro & lipids)

Q

If the body is lacking sufficient levels of amino acids, both pre- and post-exercise, the result is

A

a negative protein balance, leading to detrimental side-effects such as muscle wasting and delayed exercise recovery

16
Q

Benefits of protein timing include

A

muscle main- tenance and hypertrophy, improved exercise recovery, improved body composition and enhanced immune func- tion during periods of intense training

17
Q

type of protein consumed has also been shown to affect the

A

overall benefits experienced by athletes and measured by researchers.

18
Q

type of protein consumed has also been shown to affect the

A

overall benefits experienced by athletes and measured by researchers.

19
Q

each type of protein posses what

A

varying level of amino acid bioavailability upon consumption

20
Q

whey and casein proteins have the greatest

A

bioavailability when compared to protein alternatives,
although it is unclear whether one type provides any greater benefits over the other

21
Q

whey and casein proteins have the greatest

A

bioavailability when compared to protein alternatives,
although it is unclear whether one type provides any greater benefits over the other

22
Q

the amino acid availability in differs in

A

absorption time, composi- tion, and length of time upon consumption.

23
Q

Whey protein is

A

water soluble and is quickly digested in the body, earn- ing it the “fast protein” title.

24
Q

consumption of a casein supplement results in a

A

slower availability of amino acids, labeled a “slow protein.”

25
Q

Casein is

A

water insoluble and coagulates, resulting in a slow-release mechanism of amino acids that is sustained at increased levels in the body for a longer period of time

26
Q

Plant-based protein powders are

A

more easily digestible and have a more balanced phytonutrient profile,”

27
Q

If your system is too acidic plant proteins can

A

They can help balance the pH, encouraging detoxification and limiting inflammation.

Q

pea protein is a good source of

A

branched chain amino acids (BCAAs) that are broken down in the muscle tissue to produce energy.

carnitine

A

responsible for
