Not long ago, it seemed that there would come a day quite soon when science would reveal that every food would be toxic and every practice lethal. Or, at any rate, that is how _1_ appeared to many ordinary people.
The supposition was _2_ on half-digested and partially understood scientific reports. As a code of belief it still has its disciples—only the other day I found myself _3_ at dinner between women who, to hear them _4_, seemed to imagine that every _5_ in the supermarket was deadly. But I am pleased to report that, at long last, I detect the first signs that my fellow _6_ are beginning to emerge from the gloomy _7_ in which it has been fashionable to hide for the past 20 years or so.
There are now a handful of daring souls who are _8_ once again to eat the odd spoonful of strawberry jam and _9_ the consequences. They have noticed, perhaps, that for all the talk about refined sugar, the strawberry jam _10_ is somewhat lower than they had previously been _11_ to expect.
The _12_ of nerve, from which the ordinary person seems to be _13 _, was caused by several factors.
First, he was _14_ that it would be a good thing if he knew the _15_ of all the foods he bought. But when he saw the _16_ of ingredients dutifully printed on the sides of packets and bottles, he _17_ and feared for his safety.
The second thing which once frightened the timid but which, I do believe, is now frightening them less, was the remarkable scientific advance which, all unremarked by the general public and its legislators, has been _18_ analytical chemistry. What this galloping advance in analytical acuity means is that scientists can now isolate the tiniest amounts of _19_ substances in foods which, hitherto, have always been considered safe, or in some cases_20_.
