Interesting.
In the winter the body needs to warm up; in the summer needs to cool down. All foods and drinks (and herbs) have different properties; among them are heating and cooling. Some are obvious - chili peppers are heating, and ice cream is cooling. Some aren’t so obvious. Raw foods are cooling, like lettuce, cucumbers and most fruits. So better to eat more of them in the summer and less in the winter. It’s a matter of balancing heat vs cold, (just to use this particular example) depending on season, body type, and also health status.
