If you need to pick and choose which foods to buy organic, choose animal products and not produce.
Of course organic produce is also important to have in your diet, but non-organic meat in my opinion is much more dangerous to put into your body.
Since animal are raised on pesticide-laced feed, which tend to have a higher concentration of pesticides. Non-Organic meats have 5X as much pesticides as non-organic vegetables and non-organic butter can have up to 20X as much pesticides as non-organic vegetables.
If possible prioritize your purchases and spend the extra cash to make sure your meat hasn't been compromised.
