When cold and flu season rolls around, we often start thinking about our immune system. We reach for vitamin C, drink more tea, add a few extra vegetables to dinner, and start wondering what else we can do to stay healthy.

But supporting your immune system isn't something that needs to begin when everyone around you starts sniffling.

Your immune system is working for you every single day, and one of the best ways to support it is by giving your body the nutrition and healthy habits it needs consistently.

The good news? You don't need a complicated wellness routine.

Small, simple choices really can add up.

How Nutrition Supports Your Immune System

Your immune system is much more than one organ or one type of cell. It's a complex network that includes your skin, digestive tract, immune cells, tissues, and chemical signals that work together to help protect your body.

All of this requires nutrients.

Protein supplies amino acids your body uses to build and maintain cells. Vitamins and minerals play different roles in normal immune function, while healthy fats contribute to cell structure and help your body absorb certain vitamins.

That's one reason I believe so strongly in focusing on the whole diet rather than looking for one miracle food or nutrient.

Eat the Rainbow

You've probably heard the advice to "eat the rainbow."

There's a good reason for it.

Different fruits and vegetables provide different combinations of vitamins, minerals, fiber, and beneficial plant compounds.

Think about the variety available to us:

🍓 Red strawberries and tomatoes
🥕 Orange carrots and sweet potatoes
🍋 Yellow peppers and squash
🥦 Green broccoli and leafy greens
🫐 Blueberries and purple cabbage

Instead of worrying about eating the "perfect" fruit or vegetable, try adding more variety.

One easy challenge is to ask yourself:

How many different colors can I put on my plate today?

It's a simple approach that works for adults and kids alike.

Important Nutrients for Immune Health

There isn't one vitamin responsible for your immune system. Many nutrients work together to support normal immune function.

Vitamin A

Vitamin A helps maintain your skin and mucous membranes, which form part of your body's natural barriers.

Foods containing vitamin A or carotenoids include carrots, sweet potatoes, spinach, kale, pumpkin, and other colorful vegetables.

Vitamins C and E

Vitamins C and E have antioxidant roles that help protect cells from oxidative stress.

Vitamin C can be found in foods such as citrus fruits, strawberries, kiwi, peppers, broccoli, and tomatoes.

Vitamin E is found in foods including nuts, seeds, avocado, and some plant oils.

Vitamin D

Vitamin D plays a role in normal immune function. Unlike many nutrients, it can be challenging to get enough vitamin D from food alone, particularly depending on where you live and your sun exposure.

If you're concerned about your vitamin D level or any possible nutrient deficiency, talk with your healthcare professional about your individual needs.

B Vitamins

B vitamins, including B6, B12, and folate, contribute to normal cellular processes and immune function.

A varied diet that includes vegetables, legumes, whole grains, nuts, seeds, and other nutrient-rich foods can provide many of these important nutrients.

Zinc, Selenium and Iron

These minerals also contribute to normal immune function.

The important takeaway isn't to memorize a long list of vitamins and minerals.

It's this:

Variety matters.

Rather than putting all your attention on one vitamin, concentrate on building meals from a variety of nourishing foods.

Don't Forget About Antioxidants

You've probably heard a lot about antioxidants, but what exactly do they do?

Our bodies naturally produce molecules called free radicals during normal metabolism and other processes. Our bodies also have antioxidant defenses that help maintain balance.

Plant foods provide antioxidant nutrients and plant compounds, including carotenoids, flavonoids, and polyphenols.

This gives us another great reason to eat a variety of fruits, vegetables, herbs, nuts, seeds, and other plant foods.

Instead of searching for one trendy "superfood," think variety and consistency.

Those two words can make healthy eating much simpler.

Your Gut and Immune System Are Connected

Here's something else that's fascinating: your digestive system and immune system are closely connected.

Your intestinal lining forms an important physical barrier, and the microorganisms living in your digestive tract—collectively known as your gut microbiome—interact with your immune system.

One of the simplest ways to support a healthy gut environment is to eat plenty of fiber-rich plant foods.

These can include:

• Fruits and vegetables
• Beans and lentils
• Whole grains
• Nuts and seeds

Certain types of fiber act as prebiotics, providing nourishment for beneficial bacteria in your digestive system.

Probiotic foods contain live microorganisms, while prebiotic foods provide the fibers that help nourish certain bacteria already living in your gut.

Again, we come back to the same simple principle:

Eat a wide variety of plants.

What If You Don't Eat Enough Fruits and Vegetables?

This is where many of us struggle.

We know we're supposed to eat more fruits and vegetables, but knowing and doing aren't always the same thing.

Busy mornings happen.

Lunch gets rushed.

Dinner plans change.

And sometimes the vegetables we bought with the best intentions are still sitting in the refrigerator at the end of the week.

My approach has always been to make healthy living easier, not perfect.

Start with whole fruits and vegetables whenever possible. Add berries to breakfast. Throw spinach into a smoothie. Keep chopped vegetables ready for snacks. Add an extra vegetable to dinner.

And if you know there's a gap between the variety of plants you'd like to eat and what you're actually eating, that's also why I like Juice Plus+ Fruit, Vegetable & Berry Blend.

It's made with whole-food-based ingredients sourced from 30 different fruits, vegetables, and berries and is designed to complement your diet—not replace fruits and vegetables.

That's an important distinction.

It's about adding more plant-based nutrition to an already healthy lifestyle, not replacing healthy food.

5 Simple Daily Habits That Support Immune Health

Nutrition is important, but it's only part of the picture.

Your everyday lifestyle matters too.

1. Add another plant to your plate.
Don't completely overhaul your diet. Start by adding one more fruit or vegetable today.

2. Drink your water.
Keep a water bottle nearby and sip throughout the day rather than waiting until you're thirsty.

3. Move your body.
Walking, yoga, gardening, stretching, or another activity you enjoy all count. Consistency matters more than making exercise complicated.

4. Prioritize sleep.
Your body needs rest. Creating a calming evening routine and maintaining a consistent bedtime can make healthy sleep habits easier.

5. Find ways to manage stress.
Deep breathing, meditation, time outside, reading, yoga, or simply taking a quiet break can become part of your daily wellness routine.

Healthy Living Doesn't Have to Be Complicated

One of the biggest mistakes we can make with wellness is believing we have to change everything at once.

We don't.

Start small.

Add another vegetable to dinner.

Put berries on your breakfast.

Take a walk.

Drink another glass of water.

Go to bed a little earlier.

Try a new plant-based recipe this week.

Those simple choices become habits—and our habits are what shape our health over time.

Instead of waiting until cold and flu season to think about your immune system, make nourishing your body part of your everyday routine.

More plants. More variety. More consistency. Less pressure to be perfect.

That's a healthy lifestyle you can actually stick with.
