2 Quick Survey Who checks the protein content of foods?

3 Body composition of 70kg male

4 Importance of protein Used for all body processes Some organs need protein for survival Skin, brain, heart, liver Wolfe, AJCN 2008; 87 (suppl): 1582S-1583S

5 Importance of protein Muscle is the main reservoir of protein -supply of amino acids in fasted state

6 Importance of protein Protein response to critical illness e.g. advanced cancer, severe burns wound healing immune function Daily protein requirement up to 4 X greater than normal exercise and immunity Wolfe, AJCN 2008; 87 (suppl): 1582S-1583S, Flakoll, 2004

7 Isn t all protein the same? What is it made of Where does it come from What is complete protein How is it used by the body Effect of cooking

8 What is protein? Twenty Amino acids Twelve non essential amino acids Eight essential amino acids The body does not synthesise them so required in diet Branched chain amino acids (Leucine, Valine, Isoleucine)

9 Isn t all protein the same? What is it made of Where does it come from What is complete protein How is it used by the body Effect of cooking

10 Sources of protein Animal proteins Meat, Milk, Egg Plant proteins Pea, Soya, Flax, Wheat, Rice, Potato

11 Isn t all protein the same? What is it made of Where does it come from What is complete protein How is it used by the body Effect of cooking

12 What is a complete protein? Complete protein High quality protein Contains an adequate proportion of all of the essential amino acids Animal proteins Incomplete protein May contain all EAA s but one in a lower proportion Typically plant proteins

13 Isn t all protein the same? What is it made of Where does it come from What is complete protein How is it used by the body Effect of cooking

14 Fast and Slow Proteins How is it used by the body How fast it moves through gut Availability for digestive enzymes Passage to blood Directed to smooth or skeletal muscle FAST and SLOW PROTEINS

15 Milk Protein Milk protein Casein (acid insoluble) Whey protein (acid soluble) Whey protein Fast passage to small intestine Rapid breakdown and absorption

16 The unilateral exercise model N=8 Exercise Fed 10g EAA: Whey/Casein/Soya Tang et al, J. Appl. Physiol., 2009, in press

17 Rise in blood amino acids with proteins Tang et al, J. Appl. Physiol., 2009, in press

18 Rise in blood amino acids with proteins Tang et al, J. Appl. Physiol., 2009, in press

19 Whey protein promotes greater muscle protein synthesis Tang et al, J. Appl. Physiol., 2009, in press

20 Whey protein promotes superior gains in muscle mass lean mass (kg) 4 a,b a* a,b,c b,c c* 0 Phillips et al, J. Am. Coll. Nutr., 2008, in press Milk Whey Casein Soy CHO/placebo Protein supplement N = 290 (247 men and 43 women)

21 Fast Protein Fast Performance Rapid rich supply of branched chain amino acids Promotes benefits for muscle recovery gain with resistance type exercise reduces soreness with endurance exercise Positive immune & health related benefits Rowlands, 2008; Campbell, 2007; Saunders, 2007;

22 Isn t all protein the same? What is it made of Where does it come from What is complete protein How is it used by the body Effect of cooking

23 Isn t all protein the same? Effect of cooking Proteins are easily damaged Heating causes irreversible change e.g. egg white, meat decreased solubility slowed digestibility

24 Volac What qualifies us? Partnerships with cheese producers 40 years of specialist knowledge Low temperature filtration - high quality whey proteins - superior nutritional profiles Global market sport nutrition & health markets

25 Whey protein products

26 Assurances & Certification ISO 22000:2005 Food Safety Kosher Halal Vegetarian Informed Sport Assurance

27 WADA Code of Practice 2009 It is each athlete s personal duty to ensure that no prohibited substance enters his or her body

28 Volac and Supplement Screening Banned substance screening of whey protein ingredients since 2006 First whey protein ingredient supplier to join Informed Sport

29 INFORMED-SPORT is a supplement testing programme, designed to test supplements and/or their ingredients for inadvertent contamination with substances prohibited in sport

30 Supplements Position Statement UK Sport believes this risk minimisation service to be a positive step and welcomes the approach being taken by the industry and the HFL owned Informed-Sport Programme

31 Quick Survey Who has used whey protein as a protein supplement?

32 Why Whey Protein? The Key Reasons High quality complete protein Fast performance Immune benefits Readily available Easy to use

33 Thank you ANY QUESTIONS?
