Have you ever gone to a trendy health food spot and ordered a meal with a bajillion superfoods? Acai bowls with chia seeds, green juices made with 10-plus ingredients, and raw sweets come to mind.
The biggest misconception about nutrition from a food energetics perspective is that people prioritize nutritional content over food origin. For example, a health-conscious gal might buy imported acai from the tropics because it has a high nutritional content (and is called a "superfood") despite the fact that she lives in a climate where it's snowing outside.
If a food doesn't grow in the environment where you dwell, the food energetics take is that it's not going to give you the right kind of energy that you need, regardless of the nutrient density.
Foods that grow in warm climates are designed by nature to keep your body hydrated and cool whereas foods that grow in cold climates, like root vegetables, will warm the body.
So regardless of the nutritional content of the food, your priority should be to eat local foods that will help you adjust best to your climate. When you eat out-of-season foods, you're technically putting stress on your body (by cooling it off in a cold environment or by heating it up in a hot environment).
Simply eating local foods that help you acclimate and take stress off your body can help with weight regulation.
