Turning 60 or 70 often brings unexpected changes—stiff joints in the morning, fading energy by afternoon, or struggling with activities that once felt effortless. Many people notice strength slipping away, making simple tasks like climbing stairs or carrying groceries more challenging. It’s frustrating to feel limited while watching others stay active.
Research shows Japanese adults tend to maintain better mobility and vitality longer than in many Western countries, thanks in part to traditional eating patterns rich in nutrient-dense foods. But what if small, consistent dietary choices could support energy, joint comfort, and overall strength as you age? Keep reading to discover the everyday foods one inspiring 92-year-old Japanese fitness instructor credits for her remarkable vitality—and how studies suggest they may help promote healthy aging.

Meet Takishima Mika: Japan’s Inspiring Active Fitness Instructor
At 92, Takishima Mika (affectionately known as “Takimika”) continues teaching fitness classes, walking and jogging daily, and living with impressive energy. She started exercising at age 65 after a casual comment about her weight sparked a change. By 87, she became a certified instructor.
Her routine includes early morning walks and jogs, followed by balanced meals focused on traditional Japanese ingredients. While genetics play a role, experts point to lifestyle factors—like diet and movement—as key contributors to longevity in regions like Japan.
Studies on Blue Zones (areas with high numbers of long-lived people) highlight plant-based, fermented foods as common threads. Here’s a closer look at five foods Mika incorporates regularly, backed by research on their potential benefits for healthy aging.
Food #1: Natto – The Fermented Soybean Staple
Natto, sticky fermented soybeans, is a breakfast favorite for Mika. It’s packed with probiotics and a unique enzyme called nattokinase.
Research suggests fermented soy foods like natto support gut health and provide protein that may help maintain muscle strength. One review notes nattokinase’s role in promoting healthy blood flow.
But that’s not all—natto is also rich in vitamin K2, which studies link to bone health.
Easy tip to try: Start with a small portion mixed into rice or with mustard for flavor. Many find store-bought versions convenient.

Food #2: Plain Yogurt – Probiotic and Nutrient Boost
Mika pairs natto with plain yogurt, adding another layer of probiotics and calcium.
Studies show yogurt consumption is associated with better bone density and cognitive function in older adults. Its B vitamins, including B12, support energy metabolism.
This simple combo creates a gut-friendly start to the day.
Quick self-check: How diverse are your probiotic sources? Adding yogurt a few times a week is an easy step.
Food #3: Seasonal Vegetables and Pickles – Antioxidant Powerhouse
Fresh and pickled vegetables (like tsukemono) feature prominently in Mika’s meals, providing fiber, vitamins, and phytochemicals.
Research indicates higher vegetable intake correlates with slower age-related decline and better telomere length (a marker of cellular aging).
Mika enjoys a variety, including leafy greens, root veggies, and fermented pickles for extra probiotics.
Comparison Table: Western vs. Traditional Japanese Staples
| Aging Concern | Common Western Approach | Japanese Food Example | Potential Benefit (Per Studies) |
|---|---|---|---|
| Muscle Maintenance | Protein shakes | Natto | Supports gut health and protein absorption |
| Bone Health | Calcium supplements | Yogurt + Vegetables | Natural sources with better bioavailability |
| Daily Energy | Coffee or energy drinks | Fermented foods | Probiotics for sustained vitality |

Food #4: Banana with Probiotic Drink – Simple Potassium Pairing
For a light lunch, Mika often chooses a banana paired with a probiotic drink like Yakult.
Bananas provide potassium, which research links to healthy blood pressure. Combined with probiotics, it’s a quick, nourishing option.
This keeps things light while supporting electrolyte balance.
Food #5: Balanced Dinner with Fish, Tofu, and Fermented Sides
Evenings bring grilled fish, tofu, spinach or other veggies, and fermented items like kimchi or miso soup.
Fish offers omega-3s, associated with heart and brain health. Tofu provides plant protein and isoflavones.
Studies on traditional Japanese diets suggest these combinations support overall wellness and longevity.
Bullet-Point Benefits from Research:
- Omega-3s from fish: Linked to reduced inflammation
- Soy foods like tofu: May support hormone balance in aging
- Fermented elements: Promote microbiome diversity

- High in antioxidants and anti-inflammatory compounds
- Rich in fiber for gut and heart health
- Balanced macronutrients without excess calories
While no single food guarantees results, consistent inclusion of these may contribute to vitality.
