Figure 1: The loaf of the left is the optimised HHB$1.5 loaf. The loaf in the middle is the optimised 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). All loaves made in a home bread-making machine (Photography: Pascale Otis).

This blog reports on a study we just published on optimising the design of bread for heart health. Using linear programming we found it possible to design breads that are nutritionally superior to commercially available breads in 15 countries from a heart health perspective, as well as being lower cost. Such bread designs could be promoted by health agencies and utilised in conjunction with a government-funded bread voucher system for those at high risk of cardiovascular disease.

Notes about PHE blog:

· Peer review process: Where a blog post has a single author, then the content is always peer-reviewed by at least one senior academic in public health. This is to help ensure that statements have a reasonable basis in terms of scientific plausibility and to ensure that uncertainty is appropriately acknowledged where statements have speculative aspects. For multi-authored blogs there can also be additional peer-review. Of note is that the PHE blog posts are often well-referenced so that readers can readily check the background science and arguments.

· Competing interests: Where a blog post author has a commercial competing interest then this will be acknowledged in a statement at the end of the blog post.

· Relationship with the parent institution: Any views expressed in these blog posts are those of the author(s) alone and not their parent institution. This is consistent with the meaning of academic freedom under the NZ Education Act 1989 (section 161). Furthermore, in a free society, it is undesirable for universities to vet or otherwise control statements by academic staff.

· Comments posted to this blog: These will usually only be included if they add intellectual content to the discussions and are not abusive etc.
