healthy eating

The event promotes the agricultural and fisheries sector produce, working with farmers, fishermen and people from villages around Tonga.

RNZI reports the show started in Vava'u this week and will visit different parts of Tonga throughout July.

Chief executive of the Ministry for Agriculture, Food and Forestry, Dr Viliami Manu, said the yam crops continued to be an important part of the show and now that importance has included promotion of foods for healthier choices.

In its purest form -- that is, plain air-popped kernels -- it's a healthy, whole-grain, antioxidant-rich snack food that comes at a pretty low-calorie cost for those who like to mindlessly nibble: A three-cup serving of air-popped popcorn has only 93 calories, 1 gram of fat and close to 4 grams of fiber.

But movie theater popcorn, which is popped in coconut oil before salt and a "buttery topping" are added, is a distant cousin to its more clean-living relative.
