Four Canadian Centers will be involved: Vancouver, Toronto, Manitoba and Quebec City. The study will be partially blinded. The investigators and technical staff will be blinded but the dietitians and the patients will not be, owing to the differences in taste and appearance of the study foods. The blinding of physicians at clinic visits is likely to be difficult due to the requirement to ask questions related to diet. All patients referred to the four collaborating clinics will be asked whether they would be prepared to modify their diet if that may mean they might lower their blood cholesterol without the use of drugs. Those who checked the box for "No" or "only modest dietary change" would not be considered further. Those who checked the box for "significant" or "radical dietary change" would be invited to participate, providing they are not at high risk (<20% 10 yr risk) of CHD and were within 30% of their target LDL-C concentrations according to current Canadian Working Group recommendations i.e., those who would normally be considered for a preliminary test of diet. The three groups would be randomized to either a low saturated fat, low cholesterol diet (Step 2) or a portfolio diet both given as routine clinical advice at week zero with follow up at 3 and 6 months or more intensive advice reinforced (intensive portfolio) at clinic visits at 2, 4, 8, 12, 16 and 20 weeks. In the routine portfolio, the advice will therefore consist of two half hour sessions with the dietitian (0 and 12 weeks), compared to seven for the intensive portfolio (0, 2, 4, 8, 12, 16 and 20 weeks). Prior to starting each diet the nature of the diet will be explained to the participants and instruction on achieving diet goals will be given. Follow-up visits will be used to go over the subjects' diet record, which they have recorded over the previous 7 days, and reinforce the original dietary advice. The intensive portfolio participants will therefore receive five additional instructional and assessment follow up visits during the course of the study.
