The Lectinfree Diet
What it is: Lectin is the protein said to be responsible for causing gut problems. It’s found in just about everything. We’re talking beans, legumes, quinoa and nuts, spices like peppermint and nutmeg, fruits and vegetables like potatoes, tomatoes, eggplant, berries, watermelons, corn (including corn-fed meat) and even coffee. Legumes and wholegrain foods contain the highest amount of lectin,” says Bonnie. This diet was popularised by American heart surgeon Dr Steven Gundry.
How it works: The theory is that lectin binds to the cells in your gut and blocks the absorption of nutrients. This can affect your immune system and make you sick. But Bonnie says there’s no proof that a lectin-free diet helps with weight loss. In fact, soaking legumes and grains and cooking them thoroughly reduces the lectin significantly and prevents potential digestive problems. The diet is easy for people who hate vegetables, but isn’t particularly healthy. You don’t get much fibre, and have to make up for the lack of nutrients with expensive vitamin supplements.
Skip this if: You enjoy your food. Despite the hype, Bonnie doesn’t encourage anybody to try this diet.
