My sister is 14 and all she eats is fried food (frozen nuggets, French fries, etc.), fizzy drinks, instant spicy noodles, lemon with salt, and hot potato chips. She even eats the hot chips for breakfast with grilled cheese and ketchup. She won’t eat vegetables at all and the only fruit she’ll likely eat is strawberries with Nutella. She’s extremely picky and gets grossed out by new/unfamiliar food. Would this affect her in the future? She’s not overweight. Do you think therapy is necessary? Or any other suggestions?
