The contrast between Western and Chinese diet


I have been intrigued by the recent BBC2 programmes “The Men Who Made Us Fat”.  Not only by the profit motive that contributed to the increase in portion sizes in fast food outlets, but by the huge shift that this kind of eating created in our average UK diet, from the 1960s and 1970s onwards.  The addition of sugar and simple starches (more or less the same as sugar), in order to make “low-fat” foods more palatable, is another factor in creating addiction to sweet-tasting food and excessive consumption, leading to obesity.  These foods play havoc with blood sugar levels, making us unnecessarily hungry and therefore eating to excess. Too much sugar is also metabolised by the body into fat, creating the very effect a dieter avoiding “high fat” foods is trying to avoid. How unfair is that?  And I have been struck by how different this is from eating habits in China – more of this later.

Our western trend to obesity and poor eating has been made worse by the availability of ready meals in supermarkets, another phenomenon of the sixties, which none of us would now choose to be without.  How amazingly convenient it is, in our very busy lives, to be able to collect so many things we need from just one shop! 

So I do not have an objection in principle to supermarkets, but I do regret the ubiquity of huge portion fast food outlets, ready meals and ready mixed condiments, sauces, desserts etc.  Even more, I am troubled by the relatively low price tags attached to these items, compared to the price of fresh foods.  Along with this, I suppose, goes the reduction in parents having time to teach their children how to cook meals, and the lower amount of time at school, devoted to domestic science.  I understand that now, instead of being taught the basics of putting a balanced meal on the table, children are taught food technology.  All these factors, in my opinion, create a lack of confidence about cooking and providing nutritious and appealing food for oneself and one’s family.

As a “foodie”, I find all this quite heart-breaking!  I love food, and I love sitting down to a good meal.  Good food is a source of such pleasure!  And as an acupuncturist, aware of the traditional diet in China, balanced so carefully and naturally for nutrients, weather, time of year, time of day, and the constitution of the eater, it amazes me.  The Chinese never had problems with obesity until western food habits reached China, and still have much less of a problem than we do.  Part of the reason for this is that the Chinese cook food from scratch.  In fact, their desire for fresh food is what makes them buy fish live from the market, rather than frozen from the supermarket deep freeze, or chilled from the fresh fish counter.  Being a bit squeamish, I find it easier to buy my food the western way, but I do like it as fresh as possible, and certainly eat as little processed food as I can. 

In traditional Chinese diet, as well as being fresh, food is categorised by taste and also “energetically” – this describes foods in terms such as hot, cold, damp and drying.  We can relate these terms to some extent to western descriptions.  A drying food would probably be described by us as astringent.  Cold foods, apart from raw foods, are those that you would choose to eat on a hot summer’s day, such as melon or strawberries because they cool you down.  Yoghurt and mint are other examples of cooling foods.  A hot food is something like curry, or red wine or, interestingly, coffee. 

Taste in Chinese diet is not quite the same as in western food.  I am not thinking of stereotypical ideas of unusual Chinese foods such as birds nest soup or chicken’s feet, but of everyday foods, that we are just as likely to include in a good meal.  The Chinese have five tastes: sour, bitter, sweet, pungent and salty.  A day’s food should balance these five tastes, all of which have different digestive properties.  A good meal will also balance those five tastes (and the energetic properties described above) for the individual benefit of the eater.   So somebody who feels the cold and feels generally sluggish, might benefit from energetically hot foods, and a bias towards pungent tastes.  A hot food such as curry would be balanced with a cooling food such as yoghurt.

How to ascribe a particular taste to a particular food is also not quite the same as in the west.  Many vegetables and meats in Chinese diet would be described as sweet, not the first word that would spring to mind in the west!  Sweetness is not seen as bad in Chinese medicine; it can be a useful way of “moving the Qi”, a way to relieve stress, but the Chinese medical idea of something sweet would be half a teaspoon of honey or a small square of chocolate – not a whole bar!   In acupuncture consultation, I often find it useful to suggest foods which a patient might add to their diet, or ones they might reduce, in order to help their state of health, and these can be individually worked out, once I have made a Chinese medicine assessment.
