Keep Your Heart Health by Diet with Fish.

Fish has achieved health food status due to research that shows eating fish lowers the risk of heart disease. Public health agencies have recommended eating fish for several years. But new research continues to support additional links between diets that include fish and various measures of heart health.

While fish is a healthy source of lean protein, it is the omega-3 fatty acid content of fish, particularly fatty fish like salmon and tuna that is thought to help protect against heart disease. The key to lowering your risk of heart disease with fish seems to be eating enough fish each week to raise your blood levels of omega-3 fatty acids.

A recent study compared the omega-3 fatty acids in the blood of Japanese men living in Japan, Japanese men living in the U.S. and American men living in the U.S. Japanese men living in Japan had twice the blood level of omega-3 fatty acids and the lowest rate of heart disease as the other two groups. In addition, higher blood levels of omega-3 fatty acids in the Japanese men improved at least one measure of atherosclerosis. This and other studies provide ample evidence that it may be omega-3 fatty acids from fish and seafood that are keeping the rates of heart disease in Japan so low compared with other countries.

The omega-3 fatty acids are richest in fish with the most fat. The American Heart Association recommends that healthy people eat fish at least two times per week and to include fish like salmon, albacore tuna, mackerel, lake trout, herring and sardines. These fatty fish are rich in two of the long chain omega-3 fatty acids associated with lower rates of heart disease.

There are many ways that omega-3 fatty acids might help the heart. They are thought to reduce platelet aggregation and make the blood thinner, reduce triglyceride levels, and prevent arrhythmia. Supplementing the diet with fish or fish oil seems to greatly reduce the chances of having a heart attack. Supplementation is even being considered as a common intervention for people at a very high risk of having a heart attack.

But eating other types of fish can be heart healthy as well. Fish is low in saturated fat and eating fish can help keep levels of dietary saturated fat low and lower your risk of heart disease. And while fatty fish are highest in omega-3 fats, most fish have some of the heart these heart healthy fats. The levels of omega-3 fatty acids also vary with the diet fed to the fish. So, farm raised fish can have a very different fatty acid profile than wild fish of the same species. Because of this variability, a good approach is to eat a different types of fish and to consistently include fatty fish.
A new study compared fatty fish and lean fish for their affects on heart disease risk. While heart disease patients who were placed on a diet that included fatty fish several times per week had higher blood levels of omega-3 fatty acids at the end of the study, blood pressure actually decreased in the patients who ate lean fish several times per week. The effect of eating fish on blood pressure may be due to some other component of fish than omega-3 fatty acids.

What’s the best way to gain the heart health benefit of omega-3 fatty acids from fish? Eating fatty fish is the best way. Many research studies support the heart health benefit of eating fish. But if you can’t eat fish, don’t like fish, or can’t eat enough to meet recommendations, supplementing with omega-3 fatty acids or fish oil is a good alternative. Intervention studies have proven some benefit of taking these supplements to reduce the risk of heart disease. Talk with your health care provider if you are considering taking a dietary supplement.

Green Tea Benefits for Heart Disease?

Heart Disease — Thu, 20 Aug 2009 07:57:00 +0000

Over the last few years, green tea has garnered much attention for the possibility that it has many health benefits. Green tea has been used in Asian cultures for centuries to prevent and treat all sorts of diseases. This, coupled with the lower incidence of many serious diseases in Asian cultures, has led researchers to seriously study the health benefits of green tea.

One of the areas where green tea may have real health benefits is in preventing and treating heart disease. For example, Japanese men have one of the lowest incidences of heart disease in the world, and the Japanese are some of the most faithful drinkers of green tea; often consuming 8-10 cups per day. This information is even more compelling when you consider that nearly 75% of Japanese men smoke.

Green tea has been shown to be effective in lowering LDL cholesterol. In addition, it inhibits the formation of abnormal blood clots. Blood clots, or thrombosis, are the leading cause of heart attacks and strokes. You may find doctors beginning to prescribe green tea in addition to exercise, dietary changes and medications for lowering cholesterol.

In addition to its ability to lower cholesterol and inhibit blood clots, it also appears that the polyphenols in tea prevent the oxidation of low density lipoproteins (ldls). This is the substance that causes arterial plaque. This plaque sticks to your arteries, restricting blood flow to your heart (artherosclerosis). The plaque can also cause blood clots to form. Drinking green tea seems to prevent the buildup and reduce the risk of getting blood clots, too.

There have been a number of studies that have supported the idea that green tea is healthy for the heart. A study from the Center for Preventive Medicine at Kyushu University in Japan showed that among 302 men and 210 women, there was a significant difference in the level of atherosclerosis between the male participants who drank green tea and those who did not.*
The difference was not significant in women. The difference was noticeable in participants who drank as little as 2-3 cups per day, but was even more noticeable in those who drank 4 or more cups per day. This study concluded that green tea may be effective at preventing atherosclerosis, at least in men.

In addition to its preventive properties, there is also evidence that green tea may help patients who already have heart disease. A study from Harvard Medical School showed that tea drinkers among heart attack patients might survive longer than those who drink something else.
In this study, participants who drank at least 14 cups of tea per week were 44 percent less likely to die than those who didn’t drink tea; moderate tea drinkers (those who consumed fewer than 14 cups per week) were 28 percent less likely to die for up to four years after than those who didn’t drink tea.

Even the Journal of the American Heart Association has come on board. In 2001, they reported that consumption of green tea is likely to be beneficial to patients with heart disease. And, the Journal of Nutrition reported in 2003 that green tea was known to protect against heart disease and lower cholesterol.

Of course, the research will continue, and we will learn more about the benefits of green tea for heart disease and other health issues. One thing seems for sure; green tea does have healthy benefits, primarily due to its powerful anti-oxidants.

Anti-oxidants are one of our bodies’ best defense mechanisms because they fight free radicals that are created during the process of converting the food we eat into energy. Left unchecked, free radicals damage our cells and DNA. The cell and DNA damage caused by free radicals cause us to age more quickly, weaken our immune system and make us more susceptible to a host of serious diseases, including cancer.

But, anti-oxidants combat these free radicals, ridding our bodies of them.
Fruits and vegetables, as well as green tea are good anti-oxidant sources, and can help us fight free radicals regularly if we make them a part of our daily life.

It’s important to ensure that if you’re drinking tea for your health that it is green tea rather than traditional black tea. While black tea is a healthy beverage, it is not as healthy as green tea. This is because black tea goes through a fermentation process that changes the anti-oxidants from their original state. When this happens, some of the health benefits are lost.

So, drink up. Though there is more research to be done it does seem certain that drinking green tea is good for you. With just a few cups of this delicious beverage each day, you may be extending your life and making it healthier, too!
