Food First Doesn’t Mean Food Only

I used to think about supplements differently. Like a lot of people in the nutrition world, I saw a multivitamin as a kind of nutritional insurance policy. Eat well, take your vitamins, and you’ve covered your bases.

My thinking has since evolved

I do still believe food should be the foundation of nutrition. A varied diet built around nutrient-dense foods can provide an incredible amount of what our bodies need, and I don’t think most people need a cabinet full of supplements to compensate for a diet that’s missing the basics.

However, that doesn’t mean there are never reasons to supplement. There are plenty of situations where getting everything you need from food isn’t quite that simple.

Sometimes there really is a gap

A person might be avoiding an entire food group because of an allergy, intolerance, medical necessity, or personal dietary choice. Someone else may have a very limited appetite or be struggling to eat enough. There are also times when nutrient needs increase, such as during pregnancy or breastfeeding, or when someone’s nutritional status has been affected by illness or other circumstances.

Access matters, too. Eating a varied diet with plenty of fresh foods isn’t equally easy for everyone, and there are real-world circumstances where the ideal diet simply isn’t available or practical. Agricultural practices and soil conditions can also influence the nutrient content of foods, although I don’t think “depleted soil” is a good catch-all explanation for why everyone needs supplements.

There are also situations where the issue isn’t simply how much of a nutrient is present in a food. Absorption, digestion, medications, and individual physiology can all affect the bigger picture.

That’s where I think supplements can be genuinely useful. The question isn’t whether supplements are good or bad. The question is whether there’s a reason for this person to use this nutrient in this situation.

I don’t want supplements to replace food

When someone tells me they’re taking a long list of supplements, one of the first things I want to know is what they’re eating. Not because supplements are inherently problematic, but because a supplement can’t recreate everything that comes with eating a varied diet. Foods contain vitamins and minerals, but they also provide protein, fiber, essential fatty acids, phytochemicals, and countless other compounds that interact with one another.

So my starting point is always food. What does the person’s diet actually look like? What foods are missing? Are there restrictions or avoidances? Is there enough variety? Are there practical barriers to getting and preparing nourishing food?

Once we understand that, we can ask whether supplementation has a useful role to play.

Sometimes the answer is simply to change the food.

Sometimes there’s a nutrient gap that is difficult to close through food alone, and a targeted supplement makes sense.

What about a multivitamin?

I don’t generally view a multivitamin as something everyone needs simply because it’s difficult to eat perfectly.

There are situations where one may be useful, particularly when someone’s diet is very restricted or their nutritional needs are difficult to meet. But I’d rather understand why someone needs supplementation than automatically recommend a broad collection of nutrients just in case.

Pregnancy is an important example where I approach this differently.

Nutrient requirements increase during pregnancy, and there are certain nutrients where adequate intake is important during a very specific window of development. Prenatal supplements can help provide nutrients such as folate, iron, iodine, and vitamin D, among others.

Folate is particularly important because the neural tube develops very early in pregnancy, often before someone knows they’re pregnant. That’s one reason folic acid recommendations begin before conception rather than waiting until a pregnancy is confirmed.

So while I generally don’t think everyone needs a multivitamin, pregnancy is often not a time when I’d take a casual “food should provide everything” approach.

And then there’s morning sickness

Pregnancy also reminds us that nutrition doesn’t always happen under ideal circumstances.

If you’ve ever experienced significant morning sickness, you know that the foods you normally consider nourishing can suddenly become completely unappealing. Sometimes you’re doing your best to get through the day eating whatever you can tolerate, and that’s okay.

That may mean temporarily relying more heavily on supplementation while you’re struggling to eat a varied diet. It can also mean using targeted nutrients for a specific purpose. Vitamin B6, for example, is used in the management of nausea and vomiting during pregnancy, including in combination with a prescription medication when deemed appropriate.

The point isn’t that everyone experiencing nausea needs to start taking a bunch of supplements. It’s that context matters. Nutritional needs don’t exist in a vacuum, and sometimes the right approach has to account for what a person is actually capable of eating at that moment.

So where does that leave us?

I still believe food should come first. But I’ve become much more careful about treating “food first” as though it means “food only.”

There are times when a nutrient gap is real. There are times when dietary restrictions make it difficult to meet a need. There are times when nutrient requirements increase, when access to fresh food is limited, or when someone’s ability to eat well is temporarily compromised.

In those situations, a targeted supplement can be a useful tool. The goal isn’t to build the most impressive supplement routine or take a multivitamin simply because you aren’t sure what you’re missing. It’s to understand the person’s diet and circumstances, identify where there may actually be a gap, and use supplementation thoughtfully when it has a purpose.

For me, that’s the more useful version of food first: build the foundation with food, pay attention to what might be missing, and use supplements when there’s a good reason for them.
