Why are Avocados & Kale So Popular?

Some foods get more buzz than others, bringing in billions of dollars and shaping our daily diets. But why chia seeds and quinoa and not apples and oranges?

Avocado toast. Kale shakes. Goji berry smoothies. Quinoa bowls.

If foods were celebrities, these would be just a handful of the treats that have received the red-carpet treatment in the last few years.

But why do some fruits and vegetables become the A-listers of the food industry – highly desired produce with the ability to jump-start profits and shape the daily eating habits of billions?

Why is that kale and avocado have seen such a meteoric rise in popularity and sit centre stage basking happily in the spotlight while the humble carrot or poor old turnip remain firmly on the Z-list?
