Statistics show that 30% of us will suffer a heart attack in our lifetime. I'm one of those 30%.
After looking closely at my life, I decided that - when it came to what I was putting in my body - I needed to get my FACTS straight:
F - Fats - specifically saturated fats. I go for less than 10 g per day.
A - Alcohol - One glass of red wine per day. I don't have a glass every day. But if I miss a day, I don't get to have two the next day.
C - Caffeine - One cup of coffee per day. And that's normal coffee and a small cup. This was the biggest change I made. Well, maybe (see also S, below).
T - Tobacco - None, ever. Before the heart attack I had an occasional cigar. No more.
S - Sodium - 1500 mg per day.
It's not easy to watch 5 things all at once. But it is easy to pick one. (Easy to pick - but it will take work on whichever one you choose...) Pick one and start managing it. Work to the goal. Then make it a habit. Then pick your next one.
