Potassium Supports Cardiovascular Health

- Image via Wikipedia
For many years doctors have been insisting that seniors decrease their sodium intake in order to benefit their cardiovascular health. The doctors were emphasized that decreasing the sodium intake would ensure that seniors had healthy blood pressure levels. Typically this meant folks had to decrease the amount of table salt they consumed, because it was typically the largest source of sodium in folks diets. Recent research suggests that it is equally important for seniors to increase their potassium intake to optimize their cardiovascular health.
The research was conducted for over 10 to 15 years on more than 2,000 men and women who were diagnosed with pre-hypertension. The results showed that it was the ratio of sodium to potassium in their diets that determined their risk of suffering from the consequences of cardiovascular disease. Those who had a higher ratio of sodium to potassium showed a higher risk of cardiovascular disease events such as heart attack, stroke, or death. This is good news for seniors who are concerned about protecting cardiovascular health, because they can easily implement this preemptive aging dietary approach.
Preemptive Steps Against Cardiovascular Disease

The modern drugs that are used to treat cardiovascular disease are well known, but the modern nutritional approach to preempt cardiovascular disease is not as well known. The term cardiovascular disease is a very general term used to cover a set of conditions that are ultimately caused by atherosclerosis. Until recently atherosclerosis was simply known as “hardening of the arteries” that appeared in folks who ate too much fat and got too little exercise. Today it is known that one of the earliest triggers for artherosclerosis is oxidant damage to fat molecules. This damage alerts the immune system that swings into action, but one of the results is inflammation. These are the initial steps in a cascade of events that produce the deadly final stage of cardiovascular disease.
The medical countermeasures against cardiovascular disease are aimed at establishing the proper balance between the levels of high-density lipoproteins (HDL) and the low-density lipoproteins (LDL). Typically this means increasing the HDLs and decreasing the LDLs and triglycerides. It turns out that recent medical research has discovered a “third great wave” of cardiovascular disease prevention in terms of anti-inflammatory agents and antioxidants. This new approach offers the same benefits as the earlier approaches, but with far fewer side effects which is good news for promoting senior health against cardiovascular disease.
A Super Food for 2010!

This grain is one of the oldest grains used by humans. Barley was first used by humans in Egypt about 10,000 years ago. Late in the 15th Century it was brought to the Americas by Columbus, but barley has never gained the same popular use in the USA as other grains such as wheat and oats. Recently a number of barley’s exciting health benefits have been discovered that have particular relevance for senior health. It turns out that barley is loaded with phytochemicals, minerals and fiber that can provide preemptive aging benefits against a range of diseases. Those benefits include protection against cancer, cardiovascular disease, and unbalanced blood sugar levels.
One of the components in barley that makes it rank as a super food is a particular kind of soluble fiber known as beta-glucan. Beta-glucan is a fiber that we can not digest. It binds with water in our digestive system and slows the rate at which food moves through the digestive system. By slowing down the movement of food through our digestive system it moderates the body’s insulin and glucose responses following a meal. Among the top two grains that provide the most beta-glucan barley ranks above oats. This high beta-glucan content makes whole grain barley a super food in terms of helping folks who suffer from diabetes, because it reduces the peak glucose and insulin levels. Barley can lower the risk of cardiovascular disease by promoting healthy blood lipid levels. Other components in Barley that add to its standing as a super food are its phytonutrients known as lignans. The lignans have been shown to reduce the risk of certain cancers such as breast cancer and prostate cancer.
Phytonutrients Defend Against Age-Related Diseases

In the last ten years scientific research has validated the value of phytonutrients as a first line of defense against many age-related diseases including cancer, cardiovascular disease and diabetes. Phytonutrients are plant-based nutritional compounds. One of the outstanding phytonutrients is chia which is frequently called “the perfect food from Nature”. Chia seeds are loaded with many nutrients including protein, vitamins, minerals, antioxidants, fatty acids, and fiber. The chia seeds are edible and have a pleasant nutty flavor. Chia has been used as a food from Aztec times when it was a staple in their diet. In our time scientific research has documented chia’s ability to prevent a number of age-related diseases including cancer, cardiovascular disease, and diabetes. With over 55 million Americans currently estimated to be pre-diabetic any food that can support preemptive aging against diabetes needs to be taken seriously. The research indicates that chia can support a preemptive role in preventing diabetes and in reducing its effects in folks who are already suffering from it. In one study of diabetic patients who were at risk for heart disease those who took supplements of chia showed major improvment across a range of disease markers for diabetes including lipid profiles, inflammatory and clotting factors, and blood pressure. They also showed considerable improvement in the markers for cardiovascular disease including C-reactive protein and systolic blood pressure. Fortunately for seniors chia is available in the form of concentrated powders that will be effective in fostering senior health.
Super Foods for Seniors

The latest word on super foods with hidden benefits for senior health includes preliminary results that identify celery as a possible blood pressure reducer. The compounds in celery that are suspected of contributing to lower blood pressure are the phytochemicals called phthalides. The good news about crisp, crunchy celery is that it is very filling, it has almost no calories, and it does have a hidden health benefit. The phthalides are the cause of this health benefit, because they relax muscle tissue in artery walls and help increase bloodflow.
Amazing though it may sound the dark meat of turkey or chicken is also super food, because of the type of fats that it contains. Two thirds of the fats in dark meat are the heart healthy unsaturated fats. Over 85% of the saturated fat in dark meat has no impact on cholesterol level or it actually raises the level of the good (HDL) more than the level of the bad (LDL) cholesterol. The bottom line is that the dark meat actually lowers the risk of cardiovascular disease. Finally in terms of calories compared with white meat dark meat provides only 8 additional calories per ounce.
Lentils are the third super food on our list. They always come recommended, because they are healthy for folks, but we need to know why these hearty legumes are so healthy for us. First of all cooked lentils provide 25% more folate per cup compared with spinach. Secondly boiled lentils provide more than 15 grams of fiber per cup. Consuming colored lentils such as red, orange, or black lentils will provide additional health benefits including strong antioxidant compounds that are found in the seed hulls. They are a great substitute for rice or pasta.
Vitamin K Aids Seniors’ Hearts and Bones

When vitamin K was discovered back in 1929 it was initially believed to be required to insure healthy blood clotting. Only recently in the last ten years have other areas been researched that reveal that vitamin K has important contributions for bone and vascular health, apoptosis of cancer cells, immune support and suppression of chronic inflammatory factors. As we age one of the pathological processes that occurs is the calcification of tissues in the body. The risk of heart attacks is increased by arterial calcification. Vitamin K performs two important functions that benefit senior health. It regulates the calcium balance so that the calcium goes to our bones and not to our arteries. The good news is that vitamin K can assist in reversing arterial calcification which contributes to cardiovascular disease. In trials ingesting a higher amount of vitamin K reduced coronary artery disease by over 55%.
Vitamin K is found in two forms, K1 and K2. Foods such as organ meats, eggs and dairy provide K2. K1 is found in green leafy vegetables. The K2 in foods is much more easily absorbed into our system than is K1. Fortunately for seniors supplements containing both vitamin K1 and K2 are available at affordable prices. A caution for folks who are on anticoagulant drugs; they need to work with their physicians to achieve the optimal therapeutic INR range between the drugs and vitamin K. In conclusion vitamin K has been shown to assist getting the calcium into the bones which stops the slide into osteoprorosis. In the trials used to evaluate fracture risk vitamin K reduced hip fractures by over 70%.
Olive Oil Completes the Mediterranean Diet

The health benefits of the Mediterranean diet are well known and many folks have adopted the foods that are the basis for it. We know that it is loaded with fruits, vegetables, and omega-3 fatty acids that contribute to cardiovascular health. The Mediterranean diet is probably the ultimate diet necessary to benefit preemptive aging. What is not as well known is that the component that together with the other foods is the source of many of the Mediterranean diet’s health benefits. It turns out that particular compounds in olive oil, namely the olive oil polyphenols, contribute greatly to the diet’s health benefits.
The history of the Mediterranean diet stretches back thousands of years and its health benefits are well documented. This diet is rich in fresh vegetables and fruits, fish, wine, lean meat, whole grains and especially olive oil. The benefits have been documents over many years up to the present time. The health benefits include a reduction in the risk of cardiovascular disease, lower incidences of cancers, and neurological disorders. Recent research has verified that the polyphenols in olive oil, combined with the omega-3 from fish and resveratrol from red wine work synergistically to produce the health benefits of the Mediterranean diet.
Heart Healthy Fats for Seniors

Lately the health press has featured articles on avoiding fats in order to insure a healthy cardiovascular system. We have been warned about consuming too much animal fat in our diet, in order to avoid cardiovascular disease. Unfortunately the details about the dangerous fats are often not spelled out in detail. It turns out that we need a balance in our diet of two types of fatty acids known as the omega fatty acids. We need both the omega-6 and the omega-3 fatty acids in our diet, but we need to have the right proportions of both to promote cardiovascular health. The omega-6 fatty acids in our diet come mainly from commercial vegetable oils such as corn, soy and sunflower oils. The omega-3 fatty acids are found in fish and in plant sources such as walnuts, flax seed, and chia seed.
A goal for good cardiovascular health would require a ratio of omega-6 to omega-3 of around 4:1. Currently in this country the typical ratio is about 20:1 which is very unbalanced. This imbalance of too much omega-6 has been identified as one of the causes of the high rate of cardiovascular disease in this country. Fortunately, in addition to the natural food sources already mentioned, fish oils that are high in the omega-3 fatty acids are available in supplement form to support cardiovascular health in seniors.
Are Two Age-Related Diseases Linked?

For seniors the leading cause of blindness is age-related macular degeneration. Recent research suggests that age-related macular degeneration may be tied to chronic vascular disease. Macular degeneration appears to be tied to the gradual degradation of blood vessels in the eye. A number of researchers investigated patients for any common risk factors for vascular disease and macular degeneration. They discovered that patients already suffering from macular degeneration had elevated levels of homocysteine. Elevated levels of homocysteine are known to be a marker for for cardiovasular risk. Additional studies verified that the higher homocysteine levels were a marker for increased risk of macular degeneration in seniors. In parallel studies researchers found that C-reactive protein inflamatory marker for cardiovascular disease was equally predictive as a marker for increased risk for macular degreneration in seniors.
The researchers next investigated the possible causes of the elevated homocysteine levels. They focused on the possible vitamin deficiences that might be contributing to the elevated homocysteine levels. They discovered that the seniors suffering from macular degeneration were deficient in levels of vitamin B6, B12, and B9 (folic acid). In a study of over 5,000 women over the age of 40 who were known to be a risk for cardiovascular disease, those who supplemented with the three members of the vitamin B family had their risk of macular degeneration reduced by over 40%. This is good news for seniors, because supplementing with three vitamin Bs and eating foods rich in those vitamins with promote health eyes that are necessary for senior health.
Can Vitamin B6 Lower Heart Attack Risk for Women?

- Image via Wikipedia
In a recent ongoing study of woman’s health the effect of vitamin B6 or the lack of it in the blood stream was found to correlate with heart attacks or myocardial infarctions. The study took into consideration age, smoking status and other factors. The blood tests of the women in the study revealed higher levels of the form of vitamin B6 found in circulation for those that did not have heart attacks. A quarter of all the women in the study that high the highest level had their risk of suffering a heart attack reduced by more than 75%. In the case of women over 60 years of age with the highest level their risk was reduced by more than 60% which is very encouraging for promoting cardiovascular health for senior women.
The researchers who conducted the study noted that their findings are consistent with previous studies that showed that vitamin B6 was a cofactor in converting homocysteine to cysteine. Reducing levels of homocysteine is known to be critical in reducing the risk of cardiovascular disease. This study is apparently the first to research the relationship of vitamin B6 levels with the risk of heart attack in postmenopausal women.
