"My stomach hurts, I'm very pale and I have huge black circles around my eyes. I want all this to end. I cry every day. I'm very tired," Russian biathlon competitor Valeria Vasnetsova said on social media from inside one of Beijing's hotels.
Vasnetsova also shared a photo of what she said was "breakfast, lunch and dinner for five days already," which included a tray of plain pasta, charred meat, some potatoes and no greens. She also claimed that after investigating the food being served to other personnel, athletes were being served worse meals. She shared a photo of her team doctor's food, which included fresh fruit, a salad and prawns with broccoli.
