I remember that Roosh said he always avoids any ingredients that hurt the body in connection with testosterone/the mind. I don't have a job atm but when I did I focused on buying 100% grass fed milk, yogurts, and cheeses, and on occasion beef, if I got pork I got it without antibiotics, and *certified humane* eggs/chicken. If the package simply says "grass-fed" or "pasture raised" that doesn't mean it was grass fed to any significant degree, at the very best they grass fed it and then fattened it with corn, grain, or soy before slaughtering to give the flavor Americans like. Non-grass fed beef and dairy I would avoid completely when buying, and if you cannot afford 100% grass fed beef, dairy, yogurt, cheese, plus eggs and chicken, focus on getting your 100% grass fed dairy products and certified humane eggs and chicken meat, only buying 100% grass fed beef on occasion. Reason for getting Certified Humane is that "cage free" means literally nothing, so I look for that on egg cartons.

The only way to make this lifestyle long-term sustainable is to save fats used from cooking, food prep, and constant usage of every ingredient purchased in various recipes before considering buying new ingredients. It requires a constant increase in cooking knowledge, it can be done, but it takes time.
To make up for what cannot be accomplished without a wife or dream job to help you, intake at least 1,000 mg of vitamin c per day, in the powdered form that this lecture recommends:
Vitamin c will help prevent cancer, diabetes, sickness, heart attack, inflammatory workings in the body, and it is an anti-oxidant, so it *helps* reduce effects of things like seed oils which cause oxidation and inflammation and mental illness. In this modern age we also need more vit c to offset to the toxicity of the chemicals and car gas in the air. It actually works to offset that! It also helps your energy levels. If you take it before sleep, it's hard to fall asleep. Highly recommend watching this lecture.
