Healthy eating habits and good blood glucose control helps to prevent the occurrence of heart disease. There is no one-size-fits-all approach to diet, but it is important to have a regular meal pattern with healthy carbohydrates like whole grains, vegetables and fruits. Avoid processed, baked, and deep-fried foods, shortenings, margarine as all of these contain transfat. Limit the use of high-fat dairy products and red meat, which contain large quantities of saturated fat. Aim for less than 2300 mg sodium/day ( 1 teaspoon salt/day). Try to include vegetables, fruits, legumes rich in fiber, fish such as salmon, mackerel, tuna, and sardines rich in omega-3 fatty acids in the diet.
In short, consuming complex carbohydrates (fibre rich foods), lean protein, heart-healthy fats and improving activity levels will form healthy lifestyle modification.
