Diet and aging: Gaining a nutritional edge
=====================
Plenty of research suggests that eating healthy foods can help extend your life and improve your health.
Studies reveal that a healthy diet can help you sidestep ailments that plague people more as they age, including heart disease, hypertension, cancer, and cataracts.
There is no shortage of new and conflicting advice on diet and nutrition.
Stick to the basics with more broad-based changes, such as cutting back on meat; eating more vegetables, fruits, and whole grains; and striking a healthy balance between calories in and calories out.
Choose fruits and vegetables wisely
-------------------------
Get at least five servings of fruits and vegetables a day. When filling your plate with fruits and vegetables, choose from a full color palette.
For even more health benefits, aim for nine servings a day. To get there, choose vegetable soups and vegetable or fruit salads. Sprinkle fruit on breakfast cereal, and select it for snacks or as a sweet end note after meals.
Choose fats wisely
-------------------------
Whenever possible, use monounsaturated and polyunsaturated oils. Avoid trans fats entirely.
Limit saturated fats to less than 7% of daily calories and total fat to 20% to 30% of daily calories.
If you don’t have coronary artery disease, the American Heart Association recommends eating foods rich in omega-3 fatty acids, such as salmon, trout, or mackerel, twice weekly.
If you have documented coronary artery disease, consume roughly 1 gram a day of EPA or DHA from oily fish and supplements if your doctor advises this.
Choose carbohydrates wisely
-------------------------
Choose whole-grain foods over those made with refined grains, such as white bread.
Look beyond popular choices like whole oats and brown rice to lesser-known whole grains like barley, bulgur, kasha, and quinoa.
Limit your intake of white potatoes.
Choosing protein wisely
-------------------------
Emphasize plant sources of protein, such as beans, nuts, and grains, to help you bypass unhealthy fats predominant in animal sources.
Enjoying a wide variety of vegetables and eating beans and grains helps you get a full complement of amino acids over the course of a week.
Shy away from protein sources high in saturated fat.
Favour fish and well-trimmed poultry. If you do eat beef, pick lean cuts.
Don’t char or overcook meat, poultry, or fish — it causes a buildup of carcinogens.
Cutting off fat, which causes flames to flare on the grill, can help avoid charring; try gently sautéing, steaming, or braising these foods in liquid instead. Grilling vegetables is safe, however.
