The health supplement industry is worth billions of dollars and pounds annually. However, there is a danger that we will turn to the magic of pills or sprays to provide us with the nutrients that should be provided by foods as we restrict our diets in line with the latest official edicts.
The reality is that your body absorbs the nutrients that it requires from food, because over the last few hundred thousand years, that is how we have evolved. Not just humans but every animal across the millions of species, has also evolved that way. Which is why, however enriched a dry dog or cat food might be, it can never take the place of real meat, fish, fowl and some plants that animals would consume in the wild.
Put aside the fact for a moment that we are intelligent human beings, and look at your body as a fine example of thousands of years of fine tuning. Part of our problem with health and obesity is that we have gone from foraging and hunting and being opportunistic eaters, to being able to walk into a supermarket and pick stuff off the shelves all year around.
The body requires a wide range of nutrients to obtain what it needs, and up until the food industry began importing foreign produce and canning foods, we would have eaten seasonally. Do you get into May or June and start to crave crisp salad leaves, tomatoes, cucumber and spring onions? Do you get to October and suddenly want to dive into root vegetable stews and soups and mashed swede or parsnips with a pudding of berries on porridge? That is your ancestral instinct for seasonal foods.
Now that we can pick and choose our food to buy rather than gather… it does mean that sometimes we are not getting the right combination of nutrients together to be effective. Some nutrients require other vitamins or minerals to be absorbed by the body and this applies not only to the food that we consume but any supplements that we take.
Let me give you some examples.
You will usually see calcium supplements sold as either Calcium and Magnesium or Calcium and Vitamin D3.
