Grain fed beef has an imbalance of omega-3 to omega-6 fatty acid. Because of the grain the meat is too high in omega-6 which causes conditions that increase heart disease outcomes. Add to that sugar which your body sees anything made from wheat as sugar along with alcohol, and you are eating your self to death. Grass fed beef has the correct balance of 3 to 6. Many vegetable oils are saturated with 6 though olive and avocado oil are saturated with 3. I was in ICU in 2014 to learn about this the hard way.
I've had to change my diet to vegetables and pork\chicken\fish\range fed beef or no beef. I eat some super market beef now, and my numbers for the next week or two go to heck and freak my doctor. Same if I drink some wine or indulge with bread or pasta. Once you train your body to like those things for your whole life, you can never untrain the reactions from your body that will kill you after you change your diet away from them. And you are always slightly unsatisfied when you stop eating wheat products no matter how much veggies and protein you stuff yourself with to try and turn off your appetite.
What has created our heart problems is being addicted to certain kinds of food over our life times. Once you stop eating them, it's easy about 30 days in to see your body reacting to smells and images like a drug junky to heroin. I have to eat a sugar substitute called stevia to fool my brain becasue I get sugar cravings and I use dry roasted peanuts to take the place of my wheat cravings. Once you stop eating sugar and wheat products, you loose weight and it clears up acid reflex. Your BP and cholesterol tend to comedown too, it may also be becasue I eat oatmeal with almonds every morning now. Oatmeal reduces cholesterol and almonds effect BP.
