Joan if you want to know the truth about food in my opinion watch Game Changers on netflix.
The doctors dont know what they are doing , most of them and giving terrible advice.
The only foods that are healthy are veggies, beans, whole grains and fruit.
Oil is not healthy even Olive oil.
For best diet in the world go to Forks over Knives dot com and follow their nutriton plan. Belive me i got thousands of hours into this over the years.
Study Dr Greger lectures on youtube also or his website Nutrition Facts dot org.
