Fig. 1From: Designing low-cost “heart healthy bread”: optimization using linear programing and 15-country comparisonThe loaf on the left is the optimized HHB$1.5 loaf. The loaf in the middle is the optimized HHB$3 loaf which is high in ground linseed. The loaf on the right is one that is high in walnut (but which was subsequently excluded from further study due to its relatively high cost at NZ$5). (Photography: Pascale Otis)Back to article page
