should I not use milk from cow?

Rhonda Patrick hasn't specifically discussed the necessity to avoid cow's milk. However, she has touched on related topics in various conversations, such as the benefits of a plant-based diet and the importance of dietary choices on health and the environment. For example, she mentioned how adopting a plant-based diet can have positive environmental impacts, like reduced CO2 emissions and lower water usage 1. However, she hasn't explicitly stated that one must avoid cow's milk.

If avoiding cow's milk is part of a consideration for transitioning to a vegetarian or vegan diet, Rhonda has noted that vegetarians need to be mindful of getting all their micronutrients, as some, like iron, have lower bioavailability from plant sources compared to animal sources 2. Also, considering the complexity of nutrition, it's important to make informed choices based on what's known about different foods and diets.

It would be advisable to consider personal health goals, dietary needs, and ethical considerations when deciding whether or not to use cow's milk. Remember, this guidance from Rhonda Patrick is general and may not directly address cow's milk; consulting a healthcare professional for personalized advice would be beneficial.
