In The Plant Paradox,

Dr Gundry outlines a list of products that are ‘lectin-safe’ and a long list of those that should be avoided at all costs – these include:

• Refined starchy foods such as pasta, tortillas, rice, potatoes, bread and flour made from grains

• Grains such as wholegrains, rice, oats, quinoa and corn (including popcorn) • Sugar and artificial sweeteners (including diet soda drinks) • Vegetables such as

tomatoes (permitted only if they're peeled and de-seeded), cucumbers (again, only if peeled and de-seeded), peas, green beans, legumes, chickpeas, soy, all beans and sprouts, and all lentils • Tofu (hemp tofu is permitted)

• Nuts and seeds such as cashew nuts, peanuts, sunflower seeds, chia seeds

• All fruit, except those that are in season • Most dairy products such as cow's milk, Greek yoghurt, cheeses and casein protein powders • Grain-fed and/or soy-fed animal proteins (grass-fed animal protein and pastureraised poultry are permitted)

• Oils such as sunflower oil, grapeseed oil, canola oil, corn oil and peanut oil
