I was able to determine that the colds and sinus infections the bobinator mentions were being triggered by a chemical called carrageenan and switching to the non-dairy substitutes like Artemis reccomends only made them worse. Recently the producers of non-dairy products have stopped using carrageenan in their products so it is no longer going to be a concern. I have no issues whatsoever with raw milk from goats or cows but it is not available where I live at a price I can afford. Free-range chicken eggs, 3 a day, give me the calcium and vitamin D I need.
What worsens acne in some helps to alleviate it in others, and vice versa. Our age, gender, and other factors contribute to the clarity of our skin. What is a trigger to you will have no effect on someone else, and what triggers them might have no effect on you. I'm a teenage girl and you're a man in your 30s, so there are significant differences in factors contributing to clear skin and breakouts. The non-dairy milks I drink are all carrageenan-free.
I never made a recommendation to switch to non-dairy products, nor would I. Please reread my post, which has not been edited since it was written. I explained that "I've never had problems with acne, and I've had a limited amount of dairy since beginning my teen years. There's so many non-dairy alternatives that I
prefer. Cashew milk is my favorite." It's actually not because of concerns over acne or nutritional needs that I eased out dairy from my diet just before my 13th birthday, which is why I used care to state that it was from purely anecdotal experiences.
I try to limit all animal products except honey as a matter of personal preference. I have a nutritionist who has worked with me, my parents, and my doctor for years to help me devise a healthy eating plan, and I have routine blood work to check all of my levels and ensure that I'm satisfying my nutritional needs.
As I wrote my friend's mom who is a dermatologist has recommended that her acne-prone patients minimize (not eliminate) dairy because it
can (not a certainty) exacerbate acne. I'm sure she tailors advice specific to the patient. It's the higher GI of milk that can be more problematic. I've also read articles on Teen Vogue (hardly the site medical advice needs to be drawn from, but decent for age and gender specific skincare tips for me) about dairy consumption and acne, with heaps of comments about experiences. Maybe for dudes your age it's totally not an issue.
