You think everyone is going to control themselves just because you want them to or say they should. If I had a million dollars I'd be rich. If I was something I'm not, life would be different. People are human and for that reason we have professionals to help us along the way.
I have done a pretty good job of following what you advocate to a simpler degree. All three of my brothers and one nephew have had heart surgeries and have not followed a very healthy lifestyle. Probably forty years ago or more I bought Earl Mindell's Vitamin Bible and have followed his regime as much as I have been able to through the years.
After a routine annual checkup my doctor sent me to a cardiologist for anomalies on my EKG. Ater an ultrasound of my carotid arteries, the arteries in my extremities and a treadmill stress test he said all my doctor had seen was normal for my age and to come see him if I ever had a symptom.
After my, still not convinced and over cautious, doctor (she's a soccer mom who only has office hours three times a week) talked me into getting a CT Scan of my heart to look for calcified plaque (it was only $100.00), I went back to the cardiologist. The scan had shown a very high calcified plaque score in several of the coronary arteries. He said that there was calcification of the plaque that I had but the fact that I passed the treadmill test proved that I didn't need any intervention.
I was changed to Lipitor and have been getting over 150 minutes a week of cardio exercise and walking about 3 miles or more each day for the past year. I have a treadmill, a Bowflex, a Healthrider and a punching bag and a speed bag tower in my basement.
I told my cardiologist that I believe the fact that I had taken 1200 mg of lecithin a day for the past 40 years has helped to lessen the plaque buildup in my heart and he said that may well be.
Having said that, I recognize that I was the one that smoked for twelve years of my life and consumed sugar for most of my life leading to developing type 2 diabetes which I very well control now with pills, the diet changes and exercise.
You can bet your bottom dollar when I'm eighty years old and finally have that heart attack, I want the bypass and I'll take the vaccine when it's available now because I'm a realist and only you can be something the rest of us are not.

There is a lot to sugar alone, and how to stop consuming it, it's similar to alcohol. Most are sugarholics, there are withdraw issues when you quit consuming it.

Sugar and dairy products are long gone from my diet, but it was a personal battle, starting over many times. The body is resilient, and can repair itself given a break from onslaught, and provided the building block materials in the diet. It's never too late to start.
