Nutrition is an evolving science. One day some foods are considered unhealthy and you should stay away from them the next day – well maybe it’s not so bad. Food can be bad for you, however food can also cure. Nowhere is the evolving nature of nutrition science clearer than the fight against heart disease. Heart disease is the number 1 killer of Americans. As nutrition knowledge has grown, so has scientific understanding of heart disease, a maze of cholesterol levels, blood pressure, arterial inflammation, and lifestyle factors, such as diet, stress, and fitness levels.
The following is information that supports a heart-healthy diet:
• Soluble Fiber – acts like a scouring pad cleaning out LDL the bad cholesterol before it has a chance of sticking to your artery walls blocking blood flow. Good sources of soluble fiber are; whole grains, fruits vegetables, and legumes. These foods also contain vitamins and minerals that are good for you.
Wisdom in the past said a heart-healthy diet should be fat-free. However, that notion has changed in recent years to a diet that is “moderate” in fat. It’s the type of fat that is the problem. You need to substitute the “good” fats – monounsaturated and polyunsaturated in place of the “bad” fats – saturated and trans-fatty acids.
• Monounsaturated fats help raise the HDL cholesterol levels. HDL acts like a bodyguard and escorts the bad LDL cholesterol molecules to the liver where they are filtered and disposed of. You can find this fat in vegetable oils, nuts, olives, avocados, and fish.
• Polyunsaturated fats are helpful, but what you really want are the omega 3 fatty acids. They combat heart disease in several ways. Among these are reducing blood pressure, make your arteries more supple, and prevent arterial inflammation. Best sources for omega 3 fatty acids are cold-water fish such as salmon, Pollock, sword fish, tuna, mackerel, and herring.
Do you enjoy an occasional drink with dinner? Drinking in moderation is actually good for your heart. Alcohol makes the blood somewhat less likely to clot. We’ve all read that red wine has many antioxidants and can actually be good for you. Don’t go drinking the whole bottle. One glass is the best serving for women and two glasses for men. Beyond these amounts it will cause more harm than good.
When trying to change your diet to heart-healthy foods start with baby steps. Add a little fiber or fruit to your diet. Then maybe eat fish once to twice a week. Once you begin you will gain momentum and gradually change your nutritional diet and lifestyle.
