Welcome to another insightful session with Dr. Michael Greger, the founder of NutritionFacts.org. In this article, we’ll explore key questions and answers from Dr. Greger's recent live Q&A session, where he discusses various health topics, nutritional advice, and the importance of evidence-based nutrition.

Key Announcements

Key Questions and Answers

Vitamin C Deficiency on a Carnivore Diet

Dr. Greger discussed the potential for vitamin C deficiency when following a strict carnivore diet. While raw meat contains vitamin C, cooking it destroys this nutrient. Prolonged deficiency can lead to issues like scurvy, which may manifest within weeks, impacting wound healing and collagen production.

Green Tea Consumption

When asked about green tea, Dr. Greger recommended powdered green tea, such as matcha, over brewed tea. Consuming the whole leaf provides additional nutrients and fiber that brewing alone does not. He advised choosing Japanese sources to avoid potential lead contamination from soil in Chinese plantations.

Storage of Nuts and Seeds

Dr. Greger confirmed that storing whole flax seeds, pumpkin seeds, sunflower seeds, and walnuts in the freezer is beneficial, preserving their freshness and nutritional quality without any negative effects.

Cholesterol Levels and Health

On the topic of cholesterol, Dr. Greger emphasized the importance of lowering LDL cholesterol as much as possible through diet and lifestyle changes. He referenced recent studies indicating that very low cholesterol levels do not necessarily lead to adverse effects, which contrasts with past concerns.
