Why Mad Diet?
Our Food is Less Nutritious
The modern Western diet now lacks vital micronutrients that are essential for physical and mental well-being. Decades of intensive farming has depleted soils, studies show that fruit and veggies are less nutritious, and factory farmed meat and fish contain fewer micronutrients than before.
Due to our demanding lifestyles millions of people now rely on nutrient deficient processed foods. We often struggle to find the time to cook fresh food from scratch, and even when we do, that food is often less nutritious than the food our grandparents ate.


Experts Who Know The Score
Mad Diet began as a bestselling book authored by Suzanne Lockhart. Hailed as the 21st century ‘food bible’ Mad Diet was published by Hachette, the third-largest publishing company in the world.
In a career spanning over 20 years working with government agencies, global food manufacturers, farming groups and grocery retailers, Suzanne has insider knowledge of the politics and production of our food.
As former Vice President of a multinational science organisation Suzanne has spent decades investigating the impact of a Western diet on physical and mental health. Mad Diet is the result of 25 years of study and her front-line experience as a senior food industry executive.
