Dr Michael Lange discusses the reasons why most nuts and seeds are not as healthy as we have been led to believe.  Most nuts and seeds are very high in Pufa (poly unsaturated fatty acids) that are largely composed of pro inflammatory omega six fatty acids. Most nuts and seeds are also high in some other inflammatory unhealthy components and anti nutrients like oxalates, lectins and phytic acid .  Two nuts stand out and are considered safe by Dr Michael Lange and he allows on his Lange Survival Diet. The two nuts approved by Dr Lange are macadamia nuts and chestnuts. He says that cashews are also allowed if they are soaked overnight in water with a little lemon juice or vinegar. This process reduces phytic acid and oxalates. He says flax seeds and chia seeds are safe in very low quantities.  Both of these seeds have a good omega three to omega six ratio but they are high in phytoestrogens.  Phytoestrogens in large quantities may disrupt the hormonal system.  Pumpkin seeds and sunflower seeds are allowed in small quantities if they are either soaked over night or spouted. Dr lange does discuss the lange survival diet briefly and takes many live calls that direct the topic of conversation. He also gives a valuable promo code good for 25% off Fortifeye vitamins for a few weeks.
