Your comment mostly took the same words right out of my mouth.
I got half way down the list and realized much as just outdated opinions, not fact. Just about every once-trusted segment of our society has been politicized today. This includes the medical community. The covid scam is what outed them. Anything they claim today as being good or bad for us likely has some political motivation behind it.
The only thing I agree with is the liver, not because I think it’s bad for me, it’s because it’s nasty to smell and eat. We will be hitting the low carb diet on Jan 1st to lose weight where bacon and steak will be our best friends.
The key has always been moderation. In the 1970s, steak was a treat for us, not a regular during dinners. Donuts were served as a Saturday treat. Dad got paid on Friday, so he bought a dozen donuts at the bakery on Saturday. Bacon was served every Sunday for breakfast and on sandwiches and salads. I love liver; I always have. We stopped using margarine years ago. We cooked everything in olive oil now. But in the 1970s, we cooked with lard. Never plant-based oils. When margarine (once called Oleo) and plant-based oils emerged, people were suspicious of their health benefits and taste. It turns out the skeptics were right. We were a healthier nation until the Nineties. The cheaper products became because of additives, the less healthy we became. Growing up, soda was a treat. Today, it is on the table at every meal in many homes. As kids, we got water or milk. Adults in our family all drank either ice tea or coffee during meals.
Everything they said to avoid is good for you in moderation. Eating meat, poultry, or fish with every meal is not bad for you: control portion size and balance with an appropriate veggie and fruit. My grandmother always served apple sauce or baked apples with pork. She said it helped the body digest pork. It's an old wife's tale, maybe. My grandfather raised hogs, so pork was a regular part of our meals, and grandma lived to 95.
