Fiscal policies to improve diet have emerged as apparent effective interventions to counteract overweight and obesity and non-communicable diseases such as diabetes type 2, cardiovascular diseases, musculoskeletal disorders and some types of cancer. Furthermore, consumption of red and processed meat is linked to non-communicable diseases such as cardiovascular disease, colorectal cancer and type 2 diabetes. The consumption of less meat has a risk reducing effect on microbial food safety.
