While 2 studies reported earlier discussed dietary advice in conjunction with reducing coronary heart disease incidence, recommendations for the general public were scarcely less drastic than the diet used in the Oslo trial study. Dietary intake recommendations for the general public consisting of no more than 30% of total calories from fat sources; a disproportionate reduction in saturated fat to 10% of total calories; and no recommendation on polyunsaturated fatty acids are impractical. Examining food constituents, it was not possible to arrive at an acceptable national diet that satisfied the recommended criteria. The solution must lie in more modest and realistic objectives. One example is: reducing the present recommended 18% saturated fat intake to 13-14% of total calories (instead of 10%); and making up about half of this reduction by additional polyunsaturates. Practical trial diet demonstrations of this type need to be undertaken. A national diet on such lines could lead to satisfactory reduction in average cholesterol levels in the population by about 6%.
