Last time we were in London, the buses had low-salt ads.

The food industry has developed micro-salt which is very fine crystals of salt with very high surface area to content and now used on crisps etc. All a waste of time, just stop adding salt to everything and add loads of herbs.

""London has had a large low-salt initiative and that Londoners who go abroad now complain about salty foods."

This sounds like "activists' they-ism", as in "In Sweden" (it's always in Sweden or Denmark or Canada), "they've introduced an initiative that's now eliminated cancer"

Translated into boring facts, this always means "In Sweden, I heard at a conference lately, taxpayers' money's being spent on [fill in the latest fad]. At the conference, someone said they'd read about a Swede who should statistically ought to have got such and such a cancer, but didn't. Or was it his Finnish cousin? Anyway, it was jolly interesting."

Some manufactured products now have less salt than they used to, and this is spreading to some of the less healthy fast food operators. Real restaurants remain unaffected.

I've never encountered a Briton complain food in Italy or France is too salty.

Nanny State at work as in NY. Bad science.

Of every 100 Americans, 32 have some degree of hypertension. Not good.

But only about 30 % of those are salt-sensitive. So to help 10 people, 90 people with no problem or with problems that will not be helped by salt reduction are subject to involuntary dietary changes.

Fast food is often disgustingly salty and leaves one's mouth burning, so perhaps we should focus on teaching what real food tastes like, and not so much on "campaigns" and bans. That said, we southerners, black and white, have been notorious for eating high fat, high sugar, and high salt diets and are way too fat as a region. Moderation!

Ackislander might know the real data underlying this, but:

- in a rant from the fiendishly tyrannical holder of the Chair in cardiology at the the ancient, non-Oxbridge, hospital I was attending, the subject of Japanese salt intake came up.

- to the extent that fiendishly tyrannical females roughly my age holding medical Chairs at ancient hospitals (think James Robertson Justice playing Mrs Thatcher) are genetically capable of sheepishness, she came close to blushing

- on admitting that most Japanese eat more salt than Western McD addicts and have the hypertension of a 20 yo marathon runner, she was reduced to mumbling something about fish having less cholesterol than beef. But that I wasn't Japanese, so what was my point?

Then my mobile rang.

We never did get the answer. The consultants merely raised their eyebrows at my mention of Professor X. Somehow, I suspended "old trout" didn't refer to diets.

There have been national campaigns to try to get people's overall salt consumption down, for some years. I wouldn't be surprised if Boris has found some way to muscle in on this particular bandwagon, but I'm not aware of it.

Nanny State at work as in NY. Bad science.

Not necessarily if one reads the long article in the NY Times Magazine on processed food. The industry knows exactly what our palates desire (it spent millions on knowing that), and once the taste desire has been implanted and developed, only regulations on sugar, salt & fat will change our national habit.

All this panic over salt is misplaced. It's just the nanny state gone berserk. The fact, and I mean fact, is that there is little scientific evidence that salt does any harm. For years, it was just assumed that it increases blood pressure. Scientific studies over the last little while have shown that there is little or no demonstrable link between blood pressure and salt. E.g., http://www.stat.berkeley.edu/~census/573.pdf. Of course, many people don't want to let actual evidence get in the way of a good rant and a do-gooder crusade, so the myth that salt is poison continues to persist. Don't believe it.

That may be true, Imhornet, and I don't have HBP, but the few times I eat processed food anywhere in the world, my tastebuds are in shock at how salty eveything tastes, and frankly, I don't know why my body should be ingesting these levels of sodium that are so high that everything tastes terrible to me. I don't see why anyone needs all this salt, whether it does them harm or not. It just TASTES BAD.

I do not have the exact reference available, but I believe that the NY Magazine article mentioned that a serious reduction in salt reduced the rate of heart disease in Finland.

> I don't see why anyone needs all this salt, whether it does them harm or not. It just TASTES BAD.<

If it tasted bad to other people they'd make different choices.

choose your studies you want to believe in.

PalenQ,

Your reference (http://www.ncbi.nlm.nih.gov/pubmed/22482843 ) supports the need to reduce salt intake, which appears to be opposite to the opinion you hold: so the myth that salt is poison continues to persist. Don't believe it. Moreover, you are simplifying. Salt is necessary in our diet, but it appears that too much salt is unhealthy--that's not the same as "poison".

"Choose your studies you want to believe in" is an astute comment. These things become religion.

If you watch the science/medial press, you can tell which societies are having meetings and announcing I "revolutionary " new results. Sometimes these prove to be true, sometimes they are wrong.

We know that antioxidants in the body are good but there is fairly strong evidence that eating antioxidants doesn't do you any good. Remember Vitamin E? Now it is calcium and vitamin D added to foods tha are in question.

Every body is different, and what works for one doesn't work for all.

The best thing you can do is pick the right ancestors and eat, drink, and exercise in moderation.
