Microwave cooking is a safe technology. It’s not my favorite method of actually cooking, but it is a great tool for heating food. It is fast and convenient, and, it turns out, has a favorable profile in terms of the net effects on food nutrition.
Vani Hari’s conclusions about microwaves are all demonstrably incorrect and at odds with the scientific evidence. This seems to stem from a fatally flawed process of starting with an extreme naturalistic ideology, combined with misunderstanding and misinterpreting scientific evidence, which is used not to truly investigate or discover the truth but to back-fill her existing biases and opinions.
