The history of food science itself is littered with examples of governments sharing subsequently mistaken advice. On that basis alone, it is far too soon for governments to tax a whole major food group on the basis of speculative modeling and disputed science.
Don't listen to anecdotes; US health care is far superior.
Anecdotes are powerful in helping to persuade people, and there are good reasons to use them in debates. Yet they are always susceptible to the charge that all health systems have extreme failures. Perhaps more powerfully then, the inadequacies of the UK system show up systematically in the data about how well conditions are dealt with (data from my former colleague Kristian Niemietz’s reports here and here):
In the United States, the age-adjusted breast cancer 5-year survival rate is 88.9 percent, compared with just 81.1 percent in the UK
The United States leads the world on the equivalent stat for prostate cancer (97.2 per cent) vs. 83.2 percent in the UK
Lung cancer: 18.7 percent in the United States vs. 9.6 percent in the UK; bowel cancer: 64.2 percent vs. 56.1 percent
Just in case you think I am cherry picking: U.S. survival rates are also better for leukemia, ovarian cancer, stomach cancer, and liver cancer—all of those for which I can find comparisons
The age- and sex-standardized 30-day mortality rate for ischaemic stroke is just 3.6 per cent in the United States vs. 9.2 per cent in the UK; for haemorrhagic stroke, the figures are 22 percent vs. 26.5 percent
I could go on. All of which is to show that your probability of dying from a range of common conditions is much higher in the UK than here. Perhaps that’s why (with no hint of irony) The Guardian’s write-up of a Commonwealth Fund Report suggesting the UK’s health system was “the best in the world” said “the only serious black mark against the NHS was its poor record on keeping people alive.”
