The UK's FSA has started a campaign called "Go for Gold" to encourage people to reduce their acrylamide consumption and the media and taken it up with headlines about toast causing cancer. https://www.food.gov.uk/news-update...-go-for-gold-to-reduce-acrylamide-consumption I've looked into it and I'm frankly amazed that they would consider this worthy of a public health campaign. 1. The evidence is in vitro and rat studies not humans 2. The rats are given many times the amout humans are likely to be exposed to (up to 10,000x) 3. Studies done on humans don't show a clear link. From the EFSA "Currently, studies on human subjects have provided limited and inconsistent evidence of increased risk of developing cancer." 4. Because of 1 and 3, we cannot quantify the risk so really do not know what the effect size of not browning potatoes or whatever would actually have in real terms. 5. We have been consuming acrylamide ever since humans started to use fire, i.e. "forever". Whilst this doesn't mean it doesn't cause cancer, it makes you wonder how this could be the cause of any rise in cancer. You cannot avoid eating entirely given anything approaching a normal diet. 6. The FSA quote the Total Diet Study as showing we are "currently exposed to higher levels of acrylamide than is desirable" yet do not, as far as I could see, provide a "desirable" figure backed up with any evidence that is, or is not, desirable. 7. Given we know beyond any doubt that obesity causes a large proportion of cancers and the government has had no effect on the rising tide of obesity that is killing us, you have to wonder why they think they can talk people out of eating crisps, biscuits and chips/fries. From the Daily Telegraph: Sir David Spiegelhalter, professor of the public understanding of risk at Cambridge University, said the campaign was inappropriate. “I’m always ambivalent about public health campaigns that are not based on some pretty firm quantitative evidence,” he said. “Many things in life may increase risk, but it’s the size of the risk that makes it important.” So it would appear that we've no idea what effect size telling people to cook potatoes to a golden, but not brown, colour would have - what reduction in cancer rates it will cause.
