“The million-dollar question, literally!”
People, in general these days, tend to be aware and have heard of nutrition supplements. Even my Nani has heard of popular brands, selling different nutrients to people over the counter or via lucrative multi-level marketing and pyramid schemes. Thanks to prime-time TV adverts.
Now to jump right in, we need to understand some facts before anyone can begin to decide whether food is enough, or do we really need supplements for good health?
Pros of Produce:
Our bodies have evolved to obtain the nutrients it needs from food. An individual eating a balanced diet, with plenty of whole foods will not only receive the raw materials they need for growth, repair, energy and immunity but also the compounds that can reduce their risk of disease.
This is because, a balanced diet contains a complex medley of nutrients and other health-promoting substances, such as fiber, antioxidants and phytochemicals, which cannot be synthetically replicated.
In addition, some nutrients, including calcium, are more readily absorbed from food sources than supplements (1).
Hence, unless an individual has a specific need for a particular nutritional supplement, there is a higher possibility of harm by adding them on a daily basis in the diet, especially fat-soluble nutrients like vitamin A, high levels of which can cause osteoporosis (2) and liver damage (3), while too much of the ever-so-popular vitamin D can damage your kidneys (4).
Another noteworthy point is that the if sale of supplements is unregulated or unsupervised, it can easily lead to high self-dosage or the contents listed on the label may not match the contents of the container, outweighing any advantages.
Pros of Supplements:
Let’s face it, eating a nutritionally balanced diet, grown in an organic environment, and having a wide variety of produce, on a daily basis, may not be physically feasible at all times. Supplements can help fill in the missing components one needs for optimal health.
Additionally, during certain critical periods, the roles of supplements can be more pronounced.
Research validates that women about to become pregnant need extra folic acid, in addition to the amount of this B vitamin their food supplies (5). This helps ensure the development of a healthy baby.
In other circumstances –like old age, the absorption of nutrients is altered, (6) requiring supplements to boost or maintain and balance their nutritional status.
Nutritional supplements can also help treat a specific deficiency or help one cope with a digestive disorders, like lactose intolerance.
Thus, keeping both the arguments in mind, I would like to summarize my thoughts on the matter: Supplements can plug dietary gaps, but nutrients from food are most important.
What are your thoughts?
