What if staying healthy as you get older had less to do with finding one miracle food and more to do with the simple things you keep putting on your plate?
One woman’s routine offers an interesting starting point. At 90, she credits five humble foods that became regular parts of her diet: chokeberries, willowherb tea, buckwheat, seaweed, and sauerkraut.
Of course, no single food can guarantee that someone will avoid illness for decades. Genetics, activity, sleep, medical care, environment, and countless other factors all play a role in healthy aging.
But these five foods do have something in common: they’re simple, nutrient-rich additions that can fit naturally into an everyday routine.
1. Chokeberries: A Small Fruit Rich in Plant Compounds
Chokeberries, also called Aronia berries, have a deep purple-black color and a naturally tart flavor.
They’re particularly rich in anthocyanins and other polyphenols, which are plant compounds that have attracted considerable interest in nutrition research.
Some studies have explored chokeberry products in relation to blood pressure, cholesterol, and other cardiometabolic markers. However, the overall evidence remains uncertain, and a recent systematic review found that the available randomized trials were not strong enough to establish clear cardiometabolic benefits for the general population.
That doesn’t make chokeberries uninteresting. They’re still a flavorful way to add more fruit and plant compounds to your diet.
An Easy Way to Enjoy Chokeberries
If you have dried chokeberries, try adding a small amount to:
- Oatmeal
- Unsweetened compote
- Yogurt
- Smoothies
- Homemade trail mix
You can also make a simple fruit infusion by steeping dried berries in hot water, then straining before drinking.
Because chokeberries can be quite tart, you may prefer combining them with naturally sweeter fruits rather than adding lots of sugar.
2. Willowherb Tea: A Calming Afternoon Ritual
Willowherb, commonly referring to fireweed (Chamaenerion angustifolium), has a long history of traditional use as a herbal tea.
Its appeal may be just as much about the ritual as the drink itself: a warm cup in the afternoon can become a simple moment to slow down, especially when you’re trying to replace another caffeinated beverage.
The source recipe uses about 1 teaspoon of dried herb in 300 ml of hot water, covered and steeped for 10–15 minutes.
Drink it warm after meals or in the evening if you enjoy it.
It’s better to think of willowherb as a traditional herbal drink rather than a proven treatment for anxiety, insomnia, inflammation, or water retention. Evidence for specific health effects varies considerably between herbal products, and preparations aren’t necessarily interchangeable.
3. Buckwheat: A Simple Alternative to Refined Grains
Buckwheat has been a staple in many traditional diets for generations, and it doesn’t actually belong to the wheat family.
It’s naturally gluten-free and provides carbohydrates, fiber, minerals, and plant compounds. Its hearty texture also makes it an easy replacement for refined grains in many meals.
The source routine uses buckwheat instead of white bread and refined foods, particularly as part of meals intended to provide steadier energy.
Research on buckwheat and cardiometabolic health is promising in some areas, but the evidence is still limited and inconsistent. A systematic review and meta-analysis found that existing human studies were relatively small and had substantial variation, so buckwheat shouldn’t be presented as a treatment for diabetes or high cholesterol.
The practical benefit is simpler: it’s a filling whole-food option that can replace more refined carbohydrates.
An Easy Buckwheat Breakfast
Try cooking:
- 1 cup buckwheat groats
- 2 cups water
Simmer until tender, then serve with berries, cinnamon, chopped nuts, or a spoonful of plain yogurt.
For a savory meal, combine cooked buckwheat with roasted vegetables, herbs, mushrooms, or an egg.
4. Seaweed: A Natural Source of Iodine
Seaweed such as kelp can be surprisingly nutrient-dense.
One of its most important nutritional features is iodine, a mineral the body needs to make thyroid hormones.
That makes seaweed an interesting food to include occasionally, but there’s an important reason not to overdo it.
Kelp can contain very large amounts of iodine, and too much iodine can also interfere with thyroid function. The NIH notes that excessive iodine intake can contribute to thyroid problems, particularly in susceptible people.
So instead of treating kelp like a daily supplement, use modest portions as a food.
Simple Seaweed Salad
Rehydrate a small amount of dried seaweed according to the package instructions.
Then combine it with:
- Grated carrot
- Thinly sliced cucumber
- A little lemon juice
- Sesame seeds
- A small amount of olive or sesame oil
The result is a light side dish that can accompany buckwheat, rice, fish, or vegetables.
If you have thyroid disease or have been advised to limit iodine, check with your healthcare professional before regularly eating high-iodine seaweed such as kelp.
5. Sauerkraut: A Traditional Fermented Food
Few foods are simpler than traditional sauerkraut: cabbage, salt, and time.
During fermentation, microorganisms transform components of the cabbage, producing acids and other compounds that give sauerkraut its distinctive sour flavor.
Fermented foods are being studied for their relationship with the gut microbiome, but it’s important not to assume that every fermented food automatically qualifies as a probiotic or produces a specific health benefit. The NIH notes that not all fermented foods contain probiotics with proven health benefits.
Recent research on sauerkraut has found changes in gut microbial composition after regular consumption, although the long-term health significance of those changes is still being studied.
How to Add Sauerkraut to Your Meals
You don’t need a large serving.
Try adding a small spoonful alongside:
- Eggs
- Roasted potatoes
- Buckwheat
- Grilled chicken
- Beans
- Sandwiches
- Grain bowls
If you’re buying sauerkraut specifically for its live cultures, check the label and storage instructions. Some products are pasteurized after fermentation, which changes their microbial content.
The Real Secret May Be the Routine
Looking at these five foods together, there’s a pattern.
They’re not exotic supplements or complicated diet products.
They’re simple foods that can become part of ordinary meals:
berries in breakfast, herbal tea in the afternoon, buckwheat at lunch, seaweed with a side dish, and fermented cabbage alongside dinner.
That’s a much more realistic approach to healthy eating than searching for one ingredient that supposedly prevents every disease.
A Simple Day Inspired by These Foods
You could turn the idea into an easy daily routine.
Morning
Start with buckwheat porridge topped with berries and a few nuts.
Afternoon
Enjoy a warm cup of willowherb tea instead of another caffeinated drink if you like the flavor and tolerate the herb well.
Lunch or Dinner
Serve buckwheat with vegetables and a small portion of sauerkraut.
As a Side
Use a modest amount of seaweed in a salad rather than relying on large quantities.
Throughout the Week
Add chokeberries to oatmeal, yogurt, smoothies, or homemade compote when available.
The goal isn’t to eat all five every single day.
It’s to build a pattern of variety, minimally processed foods, and consistent habits.
Don’t Forget the Other Pieces of Healthy Aging
Food is only one part of the picture.
Regular movement, adequate sleep, social connection, stress management, preventive healthcare, and avoiding smoking can all contribute to healthier aging.
And if you have diabetes, kidney disease, thyroid problems, high blood pressure, or take regular medications, it’s worth discussing major dietary changes with a healthcare professional.
In particular, don’t assume that “natural” means unlimited. Seaweed is a good example: iodine is essential, but excessive amounts can cause problems.
Final Thoughts
The most interesting lesson from this 90-year-old’s routine isn’t that five foods can guarantee 43 years without illness.
They can’t.
It’s the idea of making simple, nourishing foods part of everyday life and sticking with those habits for years.
Chokeberries bring colorful plant compounds. Buckwheat provides a satisfying whole-food carbohydrate. Seaweed can provide iodine in small amounts. Sauerkraut adds a traditional fermented food to the plate. And willowherb can become a relaxing caffeine-free tea ritual.
None needs to be treated as a miracle.
Sometimes healthy aging is less about finding one extraordinary food and more about making ordinary good choices often enough that they become your normal routine.
