You could get Brendar Brazier's book, Thrive.. he's a vegan and eats only raw foods. he does triatholons as well.. his approach to health and moreover, healing AFTER doing a big sports event is by way of raw food. While I am not an athlete, I was however suffering from severe tendonitis and looking for "natural" ways of healing as traditional medicine was doing nothing for me. Brendan's approach to healing the body is simple and healthy. Now, even IF a person isn't a vegan and or doesn't want to eat raw food.. Brendan still writes some interesting things about recovery. Since he too is an athlete, I think your friend might benefit from what he has to say. Additionally, in his book, he too has many healthy recipes..
Also, Tim VanOrden is a vegan/raw athlete who is in his 40s.. he has many Youtube videos and tells you what he thinks is a smart way of eating. He is big on those LUNA bars... they are all raw and have only real natural ingredients in them..
Lastly, apart from sports.... if you want to do up a basket of goodies.. gotta say, Frog Hollow Farms does a YUMMY apricot spread.. using only organic ingredients.. I love their stuff.... their spreads are good if you need something sweet but without the sugar and junk... I HIGHLY recommend their products.. makes me hungry thinking about them...
