SIR; If I might be permitted to reply to Siân Harrington's revelation that she eats frozen food, I must aver that I too buy, eat and enjoy frozen food.

But I would like to put Siân's mind at rest. She is, in fact, far from being alone in her thoughts and findings on this issue.

The plain truth is that the practice of preserving food by freezing is trusted by the millions of people who eat professionally frozen foods daily, the thousands of people who freeze prepared foods and the thousands who freeze chilled foods that they have purchased.

Why is this? It is quite simply because the process of freezing is universally recognised as the only way that nature has of preserving food.

Way back in 1917, Clarence Birdseye, a biologist for the US government, discovered that the fish left over from his previous expeditions had actually been perfectly preserved by the intense cold conditions he had experienced.

He had, in reality, replicated the natural phenomenon that many indigenous peoples across the globe had used for hundreds of years to keep their food fresh.

Today, modern man has developed the freezing phenomenon into the ideal form of food preservation.

In my belief, it is absolutely imperative that the investment and belief of the pioneers of our industry should not be lost as a result of ill-informed and negative soundbites about frozen foods issuing from some parts of the media and even some of our retailers.

The drive from consumers should and will focus on areas such as health, quality and safe food, which the experts on freezing are undoubtedly determined to deliver on, not only now but also in the future.

I, for one, am delighted that Siân believes that frozen food is healthy, convenient and tasty. I must say that I wholeheartedly agree. I am 100% behind you on this, Siân. There, I have said it as well.
