The laziest part of my quest is taking
food supplements. Their promoter's promise much (too much, probably) for the simple effort of swallowing a pill. The nominally crowd-sourced reviews on their suppliers web sites invariably glow with claims of positive effect; so much so as to set my cynical synapses glowing too.
Hard science on the efficacy of these supplements is much harder to come by. On the other hand it is an established fact that mammalian metabolism changes as we age. We modify the diet of our pets as they age. There are certain foods that I disliked as a child that I now adore, and v.v. A few traditional herbal remedies, such as
St John's wort, have been well researched. Others, such as
ginkgo biloba, have credible, if controversial, reputations.
But which supplements to take, in what quantity?
Ideally I'd measure my nutritional input, have regular blood tests, and thus be able to make informed choices. But, as I have discovered, nutrition is a tricky subject: food labels generally don't include vitamin and mineral content, for example. Sites like
NutriProfile help form a general picture of nutrition, based on statistics, but cannot tell me if I have a particular metabolic affinity or resistance for any specific substance. For that I need medical tests; but unlike supplements, they are not cheap. Package deals (e.g.
here) are reasonable value as a one-off to establish a baseline. For monitoring purposes they are expensive overkill. If I was rich I'd do it; but I'm not, so I won't.
So what will I do?
I've decided to be pragmatic. The medication I'm on through the
NHS requires an annual blood test. I'm entitled to a copy of the results for a nominal fee. Until I get around to arranging that, I will start taking such supplements as research shows to be safe, and probably better than
placebo in effect.
Research has already revealed one glaring Truth, as expressed in the title of this post: supplements are not substitutes. The bad effects of gorging on burgers, sweets, and cakes, cannot be countered by any amount of supplementation. Without a healthy diet, supplements are a waste of money and hope.
