Food therapist?

M. wonders if we know someone who does food therapy in Tokyo.

"My son has terrible eating habits and although he is growing up well, we feel he needs to eat better. He is 8-years-old and eating just the same things: pizza, pasta (with just oil and salt), plain rice or with lentil sauce, rice and lentils cooked together, fries, yogurt and milk.

"He doesn't eat any fish, meat, veg, fruit or cakes. He eats little junk, few sweets and his parents have cut down on his soft drinks. He seems to have some mental block," his mother says. "We're tired of nagging him about the same thing three times a day."
