One question I hear a lot is, “What is the healthiest vegetable?”

Sometimes the question is about fruit, sometimes it’s grains, legumes, herbs, or supplements. I find that people are usually hoping for a specific answer. They want to know which food they should eat every day.

My answer is usually a surprise. Instead of answering, I ask another question. “What vegetables do you like to eat?”

Someone will tell me they love roasted Brussels sprouts but cannot stand kale. Someone else loves asparagus but can’t get themselves to eat Swiss chard. Another person eats cabbage several times a week but avoids broccoli whenever possible.

My answer is almost always the same, “Wonderful. Let’s begin there.”

Nutrition Doesn’t Come From Superfoods

For many years, nutrition advice focused on superfoods. One week blueberries were the newest superfood. The next week it was kale, turmeric, pomegranates, chia seeds, or acai berries.

Those foods are definitely nutritious, but modern nutrition science has gradually moved away from asking, “What is the healthiest food?” and toward a much more important question.

“What dietary patterns consistently show they support health?”

When researchers study populations known for exceptional health and longevity, they do not find people eating the same foods. Traditional dietary patterns in Okinawa are different from those in rural Italy. The Mediterranean region itself covers many countries with their own culinary traditions. Central America, Scandinavia, and other regions with excellent health outcomes all eat somewhat differently.

The foods vary considerably, but the principles do not. I wrote more about this idea in The Healthiest Thing I Ever Did Was Stop Looking for the Perfect Diet, where I explain why I stopped searching for one perfect way of eating and began looking for the principles healthy populations have in common.

Healthy populations tend to eat diets created around whole foods. Vegetables, legumes, fruits, herbs, nuts, seeds, and minimally processed foods show up again and again, in each country and culture. Meals are usually prepared at home, shared with friends and family, and eaten within a community that lives an active lifestyle.

I think we spend too much time looking for one magical food or one perfect combination of foods when the research points us toward something simpler: consistently eating a wide variety of whole, minimally processed foods.

The lesson is that there are many ways to create a healthy dietary pattern.

The Best Diet Is the Sustainable One

We have to look at adherence.

Researchers can design the most nutritionally impressive diet imaginable, but if we cannot maintain it, its long-term benefits are limited. As I discussed in Why Knowing What to Do Isn’t the Hard Part, information is not enough for  behavior change. The greatest challenge is finding ways to make healthy eating fit into everyday life.

People who force themselves to eat foods they don’t like because someone labeled them a “superfood” are probably not going to continue that food for very long. Eventually, they’ll get frustrated, and healthy eating begins to feel like a chore rather than a lifestyle.

That is one reason I don’t encourage clients to plan their diets around foods they don’t like. I encourage them to identify the healthy foods they already enjoy and learn how to eat those foods more often.

A person who likes eating cabbage three times a week is going to receive more benefit than someone who buys kale every Saturday intending to eat it and then throws it away the next Friday.

Nutrition cannot improve health if the food never gets eaten.

Variety Is Still Important

This does not mean we should eat the same three vegetables every day. One of the most exciting areas of nutrition research today involves dietary diversity.

Different plant foods provide different fibers, vitamins, minerals, and thousands of naturally occurring phytochemicals. Many of these compounds interact with our gut microbiome and influence everything from immune function and metabolic health to inflammation and digestion.

I don’t mean we need to eat every vegetable every week. The goal is to gradually expand the variety and diversity of plant foods that appear on your plate over time.

If someone likes spinach, maybe they will also enjoy arugula. If they like roasted carrots, they may discover they also like roasted parsnips or turnips. If cabbage is a favorite, maybe bok choy or Brussels sprouts will naturally fall into the rotation.

Being curious and trying 1 new food a week tends to create more lasting change than feeling like you have to eat something.

I Think About Food a Little Differently Now

Over the years, I have stopped asking whether a particular food is the healthiest choice. (Though I do love learning about the chemicals in certain foods!)

When working with clients, I find myself asking different questions.

• What is 1 thing you can do to eat more vegetables this week?
• What produce is in season?
• What sounds good today?
• What healthy foods fit naturally into your schedule?

Those questions lead us toward meals that are easier to enjoy. When we enjoy certain meals, we are more likely to make them again. In Sometimes the Easiest Dinner Is the Healthiest, I share one of my favorite ways to make healthy eating easier when life gets busy.

That builds consistency which is more valuable than occasionally eating the world’s most nutrient-dense vegetable.

The Bigger Lesson

One of the greatest lessons my own health journey has taught me is that nutrition is not about finding perfect foods but about creating eating patterns that are nutritious, enjoyable, and realistic enough to become part of everyday life.

There will always be a new superfood, another headline, or another expert promoting the latest nutritional discovery. Those conversations can be interesting, and many of those foods have real health benefits.

What shapes our health; however, is not the occasional, extraordinary food. It is the ordinary foods that appear on our plates day after day, year after year. That is why I no longer spend much time looking for the healthiest food.

I am more interested in helping people discover the healthy foods they genuinely enjoy, because those are the foods they will continue eating after the excitement of a new diet or a new superfood has faded.

In the end, the healthiest foods are not the ones that look the most impressive on paper. They are the ones that become a regular part of your life.
