a = significantly different from NT; b = significantly different from ST;

c = significantly different from MT; d = significantly different from MTI

4 month Fruit and Veg: ST v NT p = .01, MT v. NT p = .05, ST v. MTI p = .01, MT v. MTI p = .01

7 month Fruit and Veg: MT v. NT p = .02

4 month FHQ: MT vs. NT p = .01, MTI vs. NT p = .02, MT vs. ST p = .04
