Tongan cuisine and health
Tonga is notable for its high obesity rates with over 90% of the population being overweight. Consequently, many Tongan islanders have an increased risk of heart disease, diabetes and other obesity related diseases which place the nation's health service under considerable strain. Much of this is related to the nation's cultural love of food and eating as well as the modern influx of cheap and high-fat content meat, with corned beef and lamb belly remaining firm favourites in Tongan cuisine. Despite being a highly obese population, there is little stigma attached to being overweight as one might find in many Western civilizations. Like a great number of South Pacific cultures, large bodies are often revered, though there is growing acknowledgment of the health risks involved
