In numerous interviews, Jang Wonyoung has shared her love for eggs, chicken breast, and fish—her “golden trio” of protein-rich foods. Whether she’s maintaining her figure or cutting calories, these staples remain constant in her daily meals.
The idol reveals that protein is her secret to a toned physique, building muscle without excess fat. It’s also the key to her thick, glossy hair, achieved without reliance on chemical treatments.
Scientific studies confirm that protein is essential for keratin production, the primary component of hair structure. A protein deficiency can lead to hair loss, dryness, and slow growth. Adequate protein intake ensures healthy hair follicles, promoting faster growth and thicker strands.
Eggs are a complete protein source, containing all nine essential amino acids and biotin—a B vitamin critical for hair health. Chicken breast is an ideal lean protein, supporting muscle growth without fat accumulation. Its natural collagen boosts scalp health, strengthens hair roots, and reduces breakage.
Fatty fish like salmon, mackerel, and tuna are not only protein-rich but also packed with omega-3 fatty acids, which reduce inflammation, enhance hair elasticity, and protect follicles. According to Mayo Clinic, omega-3s increase hair density, slow natural hair loss, and improve cardiovascular health.
Beyond hair benefits, Wonyoung’s protein-focused diet sustains her slender, toned frame. Protein prolongs satiety, stabilizes blood sugar, and aids muscle development, ensuring she stays energized for her busy schedule without weight gain.

Jang Wonyoung’s favorite menu includes eggs, chicken breast, and fish—a protein powerhouse trio that nourishes hair from root to tip while maintaining her sculpted physique. These foods supply biotin, collagen, and omega-3s, ensuring both hair vitality and body balance.
If natural protein intake is challenging, consider supplements, but consult a doctor to avoid nutrient imbalances. Experts emphasize moderation and professional guidance for optimal results.
Complement Wonyoung’s trio with these “hair-saving” foods:
– Spinach & kale: Rich in iron and folate for scalp circulation.
– Avocado: Provides vitamin E and healthy fats for hair elasticity.
– Nuts & seeds: Packed with zinc, selenium, and B vitamins for follicle repair.
– Sweet potatoes: High in beta-carotene for natural scalp hydration.
A diverse diet rich in these nutrients not only enhances hair but also boosts overall health, skin vitality, and body confidence.

Through her simple dietary choices, Jang Wonyoung proves that lasting beauty stems from daily habits, not luxury products. In the glittering world of K-pop, she remains a beacon of natural charm, confidence, and energy—the epitome of a “Living Doll.”
