1. Know your fats.
Trans fat, which finds its way into foods via a process called hydrogenation, is a major culprit in the development of heart disease. Avoid it (generally, on labels, it's listed as "partially hydrogenated oil", or oil that has undergone a process to raise its melting point and reduce rancidity).
2. Keep your weight in check.
Added kilos mean added health risks—especially if they fall around your middle.
3. Shake your salt habit.
Overdoing it on sodium can lead to high blood pressure in some women, which in turn raises risk of heart disease and stroke. The recommended daily intake is 1,500mg, but you can get less!
