Martin Kintrup has written recipes in 'Paleo eenvoudig en snel' that can be prepared in a maximum of thirty minutes. Paleo stands for a dietary style with plenty of vegetables, fruit, herbs, meat, fish, poultry, eggs, nuts, and seeds, but no grains, dairy products, legumes, or refined sugars. All recipes in the cookbook are gluten-free, contain no added sugars, and are lactose-free. The recipes are described clearly and step by step.
