What Not to Eat


All grains – wheat, oats, barley, rye, couscous, etc. and anything made from them such as bread, pasta, rice, breakfast cereals. They are high in carbohydrates which are eventually treated by the body as sugar, causing surges in blood glucose and elevated insulin levels. Proteins in grains (such as gluten) cause inflammation in the body and interfere with the absorption of nutrients. Grains contain gut-irritating lectins that may cause a host of problems such as leaky gut. Gluten sensitivity is much more widespread than we think.

There are several issues with dairy consumption but it is certainly a food that some tolerate better than others. Please see this interesting article on the excellent Dallas and Melissa Hartwig’s Whole9 site:

The Dairy Manifesto



Avoid peas, beans, peanuts or any product made with these. They also contain lectins and for the reasons above should be avoided. For more information on lectins see:



There is a wealth of information out there regarding the dangers of sugar, but probably the most well-known is Robert Lustig’s talk Sugar: the Bitter Truth

Avoid sugar (simple carbohydrates) as much as possible. This includes things like syrups and honey. Fruit (also a simple carbohydrate) should be limited and eaten in smaller quantities. Fruit juices are off limits as they contain the concentrated sugar of many, many fruits in just one glass.

Don’t forget that starchy root vegetables such as potatoes, parsnips, etc. (complex carbohydrates) and indeed all starchy foods such as bread, rice etc. are still eventually recognised and treated as sugar by the body, so curb them if you have any insulin issues or are trying to lose weight. Of course starchy vegetables and fruit contain other nutrients (although sweet potatoes are particularly nutrient-dense in comparison to white potatoes) but just be aware of how many you are eating and limit them if weight loss is your goal.

For the definitive guide to the damaged induced by a high carbohydrate diet, read Gary Taubes’ Good Calories, Bad Calories, published in the UK as The Diet Delusion. This ground-breaking book blows apart the theory that ‘a calorie is a calorie’ and the mistaken assumption that we can exercise our way to losing weight. I could not put this book down. Taubes also released Why We Get Fat, which condenses the information in GCBC into a shorter, more concise format. Both of these books are essential reading.



They are very high in pro-inflammatory Omega-6 fats and contain a host of chemicals from the extraction process.
