[|Human|] I am a 65 year old man receintly widowed.  I have no knowledge about heatlhfull nutrition or amounts because my wife always took care of those specifics. I also cornory artery disease and since my wife died Ive just ate what I wanted, as much as I wanted when I wanted but I afraid Ive deteriated with this habit.  I need some guideline regarding food and nutrition. BTW Im a little over weight but not significantly.  My Doctor rarely indicates I need to loose weight.
[|AI|]  It is difficult to provide a detailed diet plan in this space. However, stick to the basics. With your risk factors I would advise the following.1) a low salt diet containing less than 2500 mg of sodium per day.2) Include lots of fruits and green vegetables in your food.3) Oil used for cooking to be kept to a minimum.4) eliminate foods with a high saturated fat intake e.g. cakes, biscuits,pastries.5) avoid red meat(mutton, beef). Stick to fish or chicken once or twice a week.6) try to get at least 30 minutes of aerobic exercise 5 times a week.
