Heart attacks are a leading cause of  death in the United States and throughout various parts of the world.  For many years physicians thought heart attacks were the consequence of a gradual narrowing of important vessels until blood could no longer pass through. Recent  studies are beginning to prove that theory wrong. Scientists have discovered that it was not a hardened narrowing of a vessel that caused these problems, but a soft plaque in the wall of the vessel that can suddenly rupture. The soft plaque that is prone to rupture is also known as vulnerable plaque. Contact your doctor for more information about vulnerable plaque and what you can do to help prevent it.

Most people are aware of what a heart attack is but many don’t know what vulnerable plaque is and the effects it has on the heart and heart attacks. In the past doctors believed that the main cause of a heart attack was due to a buildup of fatty plaque within an artery leading to the heart. This would eventually result in the artery narrowing or becoming completely blocked by a blood clot. The lack of oxygen-rich blood to the heart would then lead to a heart attack. New research is proving that theory wrong. Researchers have now found that vulnerable plaque can be a result of inflammation in the arteries which in turn leads to the development of “soft” or vulnerable plaque which when released aggressively promotes blood clotting and can result in a heart attack.

Vulnerable plaque is not a every day term that people hear about. In fact many people who are fortunate enough not to have heart problems may never ever hear the term but it is a serious one. Vulnerable plaque is a collection of white blood cells and lipids (including cholesterol) in the wall of an artery. This can result in sudden serious problems such as a heart attack. Vulnerable plaque is believed to be cause by inflammation in the arteries which leads to the development of soft or vulnerable plaque.

Eat A Fraction Of The Serving
Americans are known all over the world to have enormous portions at meal time. Whether you are in a restaurant or having dinner at home, the amount of food on your plate contributes greatly to the risk your body faces for vulnerable plaque and heart attack sings. It is best to look at your hand when measuring your portions. For example, take the size of your fist, this should be the size of your fruit portion. Vegetables or complex carbohydrates should fit cupped in your hand. Meats and proteins should be the flat of your palm.

Fruits And Vegetables
Your number one food group should be fruits and vegetables. These foods have antioxidants and help lower bad cholesterol. Eating more of them helps provide benefits that may prevents heart attack causes. Fruits and vegetables also as a whole contain less fat than other foods and some people believe them to be easier for your body to digest.

Fish Two Times
Fish is the best heart healthy item of protein in your diet. You should have 2 servings a week. It is low in saturated fat and has high levels of triglycerides. It may also lower your cholesterol and prevent **heart attack causes. Salmon, tuna, trout, sardines and mackerel are all high in omega-3 fatty acids. These servings should be broiled, baked, sauteed or grilled, never ever fry!

Whole Grain Goodness
Fiber and complex carbs in whole grain can help you feel full and help your body process foods. You become less tempted to overeat if you have a full feeling and these carbs can also help with the prevention of heart attack signs.

Nutty!
Snacks like nuts such as almonds are great for your body. They contain antioxidants and omega-3s. Make sure to choose the right nuts though. Some are high in fats and that is not a snack you want to eat when trying to prevent heart attack signs.

Good Fats
Make sure the only fats in your diet are unsaturated fats. You should also only have about 25 to 35 % of your calories come from unsaturated fats. Fats such as olive oil, safflower oil, and canola oil are all beneficial, but in moderation of course.
