Notes from DrKF:
To be clear, I am very supportive of plant-based diets—both forms of the Younger You eating plans are primarily plant-based! Yet, when I look at a diet that is exclusively plant-based, I have some concerns since there are a handful of nutrients that vegetarians and vegans tend to be deficient in. These include some of the vital amino acids—particularly the sulfur-containing methionine, cysteine, and taurine—the methyl donor vitamin B12, choline, and the omega-3 fatty acid DHA. Vitamin D levels are generally found to be lower. Even vegans who are very health conscious are still at risk of these deficiencies.
If you are following the Younger You Intensive and are vegetarian or vegan, these are the additions that will rectify any potential insufficiencies of DNA methylation–supportive nutrients due to your minimal intake or complete avoidance of animal-based foods.
