With the lack of variety in countless nutrition plans and the health of food dependent upon the ever-diminishing nutrients in soil, it’s no wonder that we’d be concerned with nutrient deficiencies. Add regular bouts of exercise, stress and medications to the mix, and all of the sudden we have a recipe for major nutrient scarcity.
How do you know if you’re deficient in nutrients?
Are your lips cracked? You may be deficient in riboflavin, niacin or pyridoxine.
Nutrient deficiencies can have a variety of effects throughout the body. Often the signs are subtle — perhaps you feel a bit “off” or your skin doesn’t look quite as glowing as it could. Occasionally the signs are more obvious. (For instance, it’s kind of hard to ignore your feet tingling, or uncontrolled muscle spasms.)
Now don’t worry — we’re not trying to scare you into buying stock with GNC and loading up on vitamin pills, or trying to turn you into a nutrient hypochondriac. We simply want to highlight some of the physical manifestations of nutrient deficiencies.
As you read through the following, you may fit the criteria for some of the deficiency symptoms. Instead of self-diagnosing and slamming a bottle of “vitamin [fill in the blank],” your concern should simply warrant further investigation into eating patterns and habits. If you notice any of the symptoms/signs fit you, then jot down some notes and initiate a dialogue with your dietitian, naturopath, chiropractor or physician (whoever you work with and trust).
Try to find a “food form” of your desired nutrient before you stock up on supplement bottles. Research suggests that nutrients tend to work better together, and are found in more complex forms in nature. For example, there are over six hundred known carotenoids, which give plants their red or orange colours. We don’t know what all of them do yet, but we’re pretty sure that many are important. Just taking a beta-carotene supplement on its own probably isn’t the same — in fact, as a few high-profile studies have shown, it may be actively harmful.
Also, as we indicate below, taking extra doses of certain vitamins doesn’t necessarily make things better. Nutrients work in complicated ways in the body, and they’re often related to one another (for example, as the amount of X increases, the body may make or absorb less of Y).
Here’s a handy guide to common deficiencies. Part 1 is organized by the body part affected, and alphabetized by part for easier navigation. Part 2 is organized by health conditions and people at risk for deficiencies.
