“Take this, it’s good for you!”
You probably heard this growing up from your parents, or grandparents, or others, about lots of things. Medicines, foods, supplements, and even activities (“Do this, it’s good for you!”). You probably have continued to hear this from other people even if you are now grown: friends, family, people you have just met, and that most reliable of all sources, random posts (I was going to say “random people” until I realized that many or most of them could be bots) on the internet! So, should you take it? I mean, is it good for you?
I know my answer is going to be shocking: “It depends.”
On what? On a whole lot of things.
The whole idea that there is a general concept of things that are “good for you”, whoever you are and what you are hoping to achieve, is nonsense. What is good for one person – say an infant or a toddler – may well not be good for a middle-aged or older adult, and vice versa. And, of course, the most important question is “good for what?” What do you seek to have happen to you that this nostrum is “good for?” Do you even share the interest in achieving the end goal that the recommender presumably does? Lower cholesterol, lower weight, more muscle mass, stronger bones, having better balance or more stamina, improved sexual function, looking younger, better bowel movements, avoiding a deficiency disease like rickets, scurvy, or pellagra? Sometimes even cheap and easily available things from which big corporations or influencers do not make a lot of money, and that in fact do work well, are also unnecessary. Parents and grandparents may push things that their parents and grandparents told them were good for them, and they might have been, back once, but are not now. Back then, when our diets were often lacking in essential vitamins, scurvy, pellagra, and rickets were real issues in the US (and may still be in some parts of the world), but are not, generally, here now. In the not-too-distant past parents gave their kids castor oil, either as a treatment for a condition that the child might or might not have, like constipation or worms, but there are much better, safer, less unpleasant, and more effective treatments for both now. (That is not considering those who gave it as punishment!)
After you have answered the question of “good for what?” and decided that that “what“ is something you want to achieve or more toward, the next set of questions are “will it do that, does it actually work?”, “does it work for everyone the same or are there some groups of people (based on age, gender, health status, etc.) for whom it works better or not as well, and “what are the untoward effects that may, or even are likely to, happen, which may be far worse than the benefit?” Anabolic steroids, for example, do work to increase muscle mass, endurance, and power (see: sports stars) but also cause serious bad things (liver disease, testicular shrinkage, and a host of others). If it is legal and you are not competing in a sport where it is banned, it is up to you to decide whether the risk:benefit ratio is one you are willing to take (provided you are an adult, since in this area as many others, teens are poor judges of risk:benefit and do not have a good long view). Psyllium seed powders can be good for your bowels, lowering cholesterol, and helping to control your appetite, but some people have problems with the side effects. Testosterone, now being pushed by the Secretary of War who is competing with the Secretary of HHS and the President for being the administrations most macho ignoramus, can be good for some people who are deficient who should not be, but is far from a panacea that turns regular people into mindless Orcs (many medical professionals disagree, Doctors question evidence behind Pentagon testosterone plan). By the way, this is a good time to note the intrinsic contradictions in the “men’s health” movement. Its two big issues are prostate disease (especially cancer) and “low T”. Testosterone will not only make prostate cancer (or even benign prostatic hypertrophy) worse, blocking endogenous testosterone is the mainstay of treatment for prostate cancer. Oh, well, let’s see what it does for Pete Hegseth.
Some things generally are good for you. For example, age-appropriate vaccines are good for almost everyone (except those with known allergies to its components or previous severe reactions, by which I mean things like Guillain-Barre Syndrome, not a sore arm or short-term fever). Virtually all vaccines for children and adults (MMR, DTP, meningococcus, chicken pox, H. flu, influenza, Covid, shingles, polio, etc.) are really wonderful miracles that save thousands (sometimes millions, see: “Covid” and influenza) of lives, even more thousands or millions saved from serious morbidity, and with a very low rate of any significant negative effect. This is true. If you hear different information from your favorite TikTok star or Facebook friend, or Secretary of HHS, they are wrong.
Some things are generally bad for almost everyone, like taking dangerous drugs for unapproved indications (e.g., ivermectin for Covid), not to mention drinking or injecting bleach! The internet is full of recommendations for magic bullets that will cure whatever ails you or doesn’t even ail you but tells you it will or might if you don’t buy their solution. These claims are no more reliable than the clothes, makeup, hardware, and amazing items that will solve all your household worries. That is, some may be of value, for some people, in some circumstances, but often are not and even are dangerous, but all make money for those selling them (or in the modern world, selling their ability to influence others to the companies that make the products).
A big issue, it seems, is whether to take drugs, especially prescription drugs, manufactured by big, evil, pharmaceutical companies and heavily advertised by them, or to take “natural” over-the-counter drugs made by any-old-person or company and pushed by – any-old-person (or bot). Pharmaceutical companies are evil, as are most huge for-profit corporations (and they are usually the most for-profitable!) because their profits, not your health, is their main function. This does not mean that their products (or at least all of them) are not effective or safe when “used as directed”. They have two important characteristics non-prescription, even “natural” remedies, do not. First, they are tested, and approved after an extensive process, by the FDA (or were, before the FDA was decimated by the administration), which other remedies are not. Second, the doses are standardized, so you know what you’re getting. Even when plants (natural) are the basis for the drugs – say willow bark for aspirin – dosing is an issue. How much willow bark? From how old a tree? Growing in what setting? An aspirin tablet is standardized. Taking unregulated medication is akin to taking street opiates – you cannot be sure what, and how much you are getting. Plus, remember “natural” is not intrinsically good, safe, or protective. There are at least as many natural poisons as beneficial substances. If something you ingest, “natural” or manufactured, has a biologic effect that you desire, it also can (and likely does) have biologic effects that you do not desire (“side effects”, a term meaning biologic effects you don’t want). Testing and standardization are keys. Not that this in any way excuses the rapacious profit-taking of Pharma, but neither does it of those selling unregulated nostrums.
Finally, and I have said this before and will say it again, when thinking about whether something is “good for you” and whether you should take it, anything that sounds too good to be true probably is.
