As I turn 45 this week, I've been thinking about how much my perspective on nutrition has changed over the years.
I've been interested in nutrition for as long as I can remember. I went on to earn my nutrition degree, become a registered dietitian, and spend nearly two decades working in nutrition, much of that time helping children and families build healthier relationships with food.
But what I believe about healthy eating today isn't exactly what I believed in my 20s.
My understanding of nutrition has evolved alongside my career, becoming a mom to two boys, and simply getting older. Some things I once prioritized don't seem quite as important anymore, while other things have become much more meaningful.
I still believe nutrition matters. I still love talking about the benefits of fruits and vegetables, helping families build balanced meals, and making nutritious food accessible and enjoyable.
But I've also learned that healthy eating isn't about following a perfect set of rules. It's about finding a way of eating that nourishes you, fits your life, and allows you to enjoy food along the way.
Here's how my perspective has evolved through my 20s, 30s, and now my 40s.
In my 20s: Learning the rules and sharing what I knew
In my 20s, I was very focused on nutrition and what I considered healthy eating. I was interested in it long before I earned my degree, and as I learned more about nutrition, I became increasingly focused on what I should eliminate from my diet.
Trans fats? Avoid them. Sugar? Limit it. Processed foods? Minimize them. I was very much in the eat clean mindset, looking for ways to remove foods and ingredients that didn't fit my definition of healthy.
Of course, I was in my 20s, too. I enjoyed going out, socializing, and having fun, so I wasn't following those rules perfectly all the time. But the underlying mindset was there: healthier eating meant avoiding the things that weren't good for me.
Looking back, I don't think that focus was entirely misplaced. Understanding nutrition matters, and the science I learned continues to inform my work today. But I hadn't yet fully appreciated how complicated eating can be beyond the science.
Knowing what to eat doesn't automatically mean you have the time, resources, energy, or desire to eat that way. Food choices are influenced by so much more than nutrition knowledge, including habits, preferences, emotions, culture, family dynamics, and what is realistic in everyday life.
What I've learned since: Nutrition education is important, but information alone doesn't change behavior. Healthy eating isn't simply about knowing which foods to choose or which ingredients to avoid. It's about finding an approach that works in real life, is enjoyable, and can be sustained over time.
In my 30s: Learning to make nutrition work in real life
Becoming a mom changed how I thought about food in ways I hadn't anticipated.
Suddenly, I wasn't just thinking about my own nutrition. I was feeding a family, navigating little-kid preferences, and figuring out how to get meals on the table day after day. Juice cleanses and rigid ideas about clean eating became a lot less practical. I became more focused on balance, variety, and making nutritious meals work for our family. I also became more relaxed about snack foods and the reality that not every meal needed to be perfect.
I wanted my boys to enjoy food and experience a wide variety of flavors and textures. We cooked together, visited farmers markets, and made family meals part of our routine. I wanted them to learn about food, but I also wanted them to enjoy it.
My professional experience as a pediatric dietitian reinforced how important these early experiences can be. I became increasingly interested in not just what children eat, but how they learn to eat and how their experiences shape their relationship with food.
I realized that I could offer nutritious foods, encourage variety, and create opportunities for my kids to explore new foods without needing to control every bite they took.
What I've learned since: Healthy eating has to fit into real life. It needs to work for busy families, changing schedules, different preferences, and imperfect days. And when we're feeding kids, the goal isn't just to get nutrients into their bodies today. It's also to help them build confidence around food and develop habits that will serve them for years to come.
In my 40s: Paying attention to what my body needs
Now that I'm in my 40s, I'm noticing more how food affects me personally.
Hydration has become a bigger priority, and I pay more attention to getting plenty of fruits and vegetables. I notice that alcohol doesn't agree with me quite the way it used to, and dairy can affect how I feel, too. I'm also more open to considering supplements when they make sense for my individual needs.
It's not that I'm looking for a new set of rules to follow. It's more that I'm paying attention to my body's responses and recognizing that what works for me can change over time.
I also think differently about the role nutrition plays in overall health. Food is important, but so are movement, sleep, stress, relationships, and the ability to enjoy life. I want to feel good, stay active, support my health as I age, and have the energy to do the things I love. Nutrition is part of that picture, but it isn't the whole picture.
What I've learned so far: Healthy eating isn't one-size-fits-all, and our needs and priorities evolve throughout life. It's worth paying attention to how we feel, making adjustments when needed, and being thoughtful about our choices without turning every meal into a decision we need to get right.
What nearly 20 years as a dietitian has taught me
Beyond the changes in my own life, working with children and families has reinforced a few things I believe even more strongly today.
You can care about nutrition without striving for perfection.
A healthy pattern of eating leaves room for flexibility. One meal, snack, or food choice doesn't define your health.
Adding nourishment can be more helpful than focusing on restriction.
Rather than constantly thinking about what to avoid, look for opportunities to add foods you enjoy, variety, fiber, satisfying meals, and nutrients that support your health.
How we feed our kids matters, but so does how they feel about food.
We can encourage variety, provide nutritious meals, and support growth without pressuring children to eat or making certain foods feel forbidden.
Health is about more than nutrition.
Movement, sleep, connection, time outdoors, and enjoying your life all matter. Food should support your life, not take it over.
A few thoughts as I turn 45
I don't think my younger self was wrong about everything. I still value the science of nutrition, and I'm grateful for the foundation I built early in my career.
But I have a much broader understanding of what healthy eating looks like today.
It's less about following rules and more about finding balance. Less about eliminating foods and more about nourishing ourselves. Less about getting every meal right and more about the habits and experiences we build over time.
And when it comes to raising healthy eaters, I think that distinction matters even more. I want my kids to understand that food can nourish their bodies, give them energy, and support their growth. I also want them to know that food is meant to be enjoyed, shared, explored, and sometimes simply eaten because it tastes good.
At 45, I still have plenty to learn. But if there's one thing I hope my years as a dietitian have taught me, it's that healthy eating doesn't have to be complicated or stressful to be meaningful.
It just needs to work for you and the life you want to live.
