What you should eat to get all micronutrients you need

Maybe you’ve been there: You read about magnesium in pumpkin seeds, iron in lentils, omega-3 in fish, vitamin C in bell peppers, and vitamin K in green vegetables. Then there are B vitamins, iodine, zinc, selenium, calcium, and vitamin D—and suddenly, eating a balanced diet feels almost like a scientific project.

Yet nature is surprisingly practical. Our bodies aren’t designed to get all our nutrients every day in precisely calculated amounts from individual “superfoods.” What matters far more is how varied and nutrient-rich our diet is over the course of days and weeks. The key question, therefore, isn’t “Which food contains the most micronutrients?” but rather “How do I structure my diet so that different foods complement each other effectively?”

This is precisely where it becomes clear: Good nutrition is rarely a matter of finding that one perfect food, but rather of the smart interplay of many building blocks.

How to Improve Your Nutrient Intake

If you want to ensure a reliable supply of a wide range of micronutrients, you don’t need exotic powders, expensive superfoods, or complicated meal plans. Above all, you need variety. That’s because every food has its own unique nutrient profile. Whole grains, for example, provide magnesium and B vitamins, among other things, while legumes are rich in plant-based protein, folate, iron, and other minerals. Nuts and seeds provide unsaturated fatty acids, magnesium, and—depending on the variety—other minerals.

So the key lies less in the perfect individual food than in the combination. You could think of it like a puzzle: No single piece shows the whole picture. But the more different pieces you put together, the more complete the picture becomes.

5 Food Groups That Make Your Micronutrient Intake Especially Diverse

Instead of going through an endless list of individual foods, it’s more helpful to focus on the key building blocks of a varied diet. Above all, there are five food groups you should incorporate into your daily diet.

1. Vegetables—preferably colorful and varied

The more varied the colors on your plate, the greater the variety of plant compounds it typically contains. Green leafy vegetables like spinach, Swiss chard, or kale can provide folate, vitamin K, and—depending on the variety and preparation—other micronutrients. Bell peppers and other colorful vegetables, for example, provide vitamin C and various phytochemicals. Root vegetables like carrots or sweet potatoes, in turn, provide different plant compounds. The practical rule is therefore: Don’t eat exactly the same vegetables every day. Vary the types, colors, and preparation methods.

Frozen vegetables are by no means a poor alternative. On the contrary: They can be a very practical way to have nutrient-rich vegetables on hand even when they’re out of season.

2. Legumes—the Underrated All-Rounders

Lentils, beans, chickpeas, and peas are true nutritional powerhouses. They provide plant-based protein, fiber, folate, and various minerals. At the same time, they can help make meals more filling.

You don’t have to soak a large pot of dried beans overnight. Pre-cooked legumes from a jar or can are a quick and easy option. Just rinse them and add them to salads, soups, curries, or vegetable stir-fries.

And here’s another interesting point: While the body generally absorbs plant-based iron less efficiently than iron from animal foods, vitamin C can improve the absorption of plant-based iron. That’s why a lentil soup with bell peppers or a bean salad with lemon juice isn’t just a great combination in terms of flavor.

3. Whole Grains—More Than Just Fiber

Whole-grain products are sometimes reduced to just their fiber content. But they can offer much more than that. Oatmeal, whole-grain bread, whole-grain rice, and other whole grains provide, among other things, B vitamins and minerals like magnesium—and they add complex carbohydrates and fiber to a meal.

Start your day, for example, with whole-grain bread or plain yogurt topped with rolled oats, nuts, and berries. The combination of grains, dairy, nuts, seeds, and fruit is particularly nutrient-rich.

4. Nuts and Seeds – Small but Packed with Nutrition

Nuts and seeds are high in energy but also have a high nutrient density. Almonds, walnuts, hazelnuts, pumpkin seeds, sesame seeds, and flaxseeds each provide different fatty acids, minerals, and other valuable nutrients, depending on the variety.

A small portion in muesli, sprinkled over a salad, or added to soup can therefore be an easy way to enhance your meals. Here, too, you can mix it up however you like.

5. Fish, Eggs, and Dairy Products—If You Eat Animal-Based Foods

Animal-based foods can also contribute to your micronutrient intake. Depending on the species, fish provides iodine and omega-3 fatty acids, among other nutrients. Eggs, for example, contain vitamin B12 and choline. Dairy products can make an important contribution to your calcium intake.

For people who follow a vegetarian or vegan diet, it is especially important to pay close attention to specific nutrients. In a vegan diet, vitamin B12 must be reliably obtained through supplements. Careful planning can also be helpful when it comes to iodine, iron, calcium, vitamin D, and omega-3 fatty acids.

What are common nutrient deficiencies?

It’s worth taking a moment to assess the reality here. Even a very varied diet cannot automatically meet all micronutrient needs at all times. Vitamin D is a good example of this. The body can produce vitamin D on its own with the help of sunlight. In Germany, however, vitamin D intake is often insufficient, especially during the months with little sunshine.

Iodine is another nutrient that many people should pay attention to. Since the soil in Germany and large parts of Central Europe is naturally low in iodine, many foods contain only small amounts. Good sources of iodine include saltwater fish, dairy products, and eggs, although the iodine content—especially in milk—depends on the animals’ diet.

Vitamin B12, iron, and folate are also among the nutrients where intake is often insufficient, as requirements and intake can vary depending on diet, life stage, and individual health factors. A broad range of dietary supplements may be helpful here to ensure adequate intake.

Preparation methods can also vary

Storage and preparation also play a role in the bioavailability of micronutrients. Cooking, for example, can increase the bioavailability of certain plant compounds (such as lycopene from tomatoes and beta-carotene from sweet potatoes and carrots), while some heat-sensitive vitamins may be lost.

That’s why it’s a good idea to vary your cooking methods: sometimes raw, sometimes steamed, sometimes baked, sometimes in soup. This isn’t just more interesting from a culinary perspective—it also changes which nutrients are available and in what form.

A Simple Principle for Your Daily Life

If you don’t want to study nutrition facts labels every day, you can follow a simple principle: Try to combine different food groups throughout the day.

A balanced meal ideally consists of:

½ plate: Vegetables and/or salad

¼ plate: A source of protein such as legumes, fish, eggs, tofu, or dairy

¼ plate: Whole grains, potatoes, or another filling side dish

Plus a small portion of nuts or seeds and some fruit spread out throughout the day

This doesn’t have to be followed perfectly at every meal. It’s more of a general guideline. After all, your micronutrient intake isn’t determined by a single lunch. It results from the pattern that repeats itself over many meals, days, and weeks.

Conclusion: It’s not any single superfood that makes the difference—it’s variety.

You don’t have to eat perfectly. Nor do you have to work through a new list of “10 especially healthy foods” every day. If your diet is varied throughout the week and regularly includes vegetables, fruits, whole grains, legumes, nuts, and seeds—as well as fish, eggs, or dairy products, depending on your dietary preferences—you’ll lay a solid foundation for a diverse intake of micronutrients.
