What Kind of Milk to Drink for High Blood Pressure

More than 65 million Americans suffer from high blood pressure, according to “Your Guide to Lowering Your Blood Pressure with DASH.” This condition occurs when the force of blood against your artery walls is persistently higher than normal, which should be 120 millimeters of mercury, or mmHg, over 80 mmHg, or lower. If hypertension is not properly treated, it can lead to blindness, heart disease or kidney disease. Changing the type of milk you drink is just one part of a dietary approach to treating high blood pressure.
Low-Fat or Fat-Free
The Dietary Approaches to Stop Hypertension, or DASH, diet recommends consuming foods and beverages that are low in fat, such as low-fat and fat-free milk. Whole milk is rich in saturated fat, with 1 cup of 3.25 percent whole milk containing nearly 8 grams of fat — and nearly 4.6 grams of that is saturated fat. On the other hand, fat-free or skim milk contains just 0.2 grams of fat, with just 0.125 grams being saturated fat.

Avoiding Fat
Fat, especially saturated and trans fat, increases your risk of gaining weight, which in turn makes you more likely to have high blood pressure. If you’ve already been diagnosed with high blood pressure, carrying extra weight makes your condition worse. Hypertension also increases your risk of other cardiovascular conditions such as atherosclerosis, which is characterized by a buildup of blood fats and other substances along the walls of your arteries. A high-fat diet worsens atherosclerosis and other cardiovascular problems.

Binge drinking, high blood pressure a lethal combo

It's no secret that high blood pressure increases your risk of heart disease and stroke. Nor should it come as a surprise that binge drinking isn't the healthiest habit. But a new study suggests that combining the two may add up to double the trouble -- and much more, in some cases.
Compared with teetotalers with normal blood pressure, men with high blood pressure (hypertension) who even occasionally down more than six drinks in one sitting have nearly double the risk of dying from a stroke or heart attack, according to the study, which followed 6,100 South Koreans age 55 and up for two decades.
If men with high blood pressure have 12 drinks or more at one time, their risk is nearly five times higher, the study found.
"Somehow the binge drinking compounds [high blood pressure] -- and more than just a little bit," says Brian Silver, M.D., a neurologist at Henry Ford Hospital, in Detroit, Michigan, and a spokesman for the American Heart Association.
But the researchers, who are based at Yonsei University, in Seoul, can't say for sure that binge drinking directly caused strokes and heart attacks in the hypertensive men. The study was based on surveys and did not take into account the timing of the binge drinking and subsequent cardiovascular events.
Still, the findings ring true, says J. Chad Teeters, M.D., a cardiologist at the University of Rochester Medical Center, in New York.
"There have been studies that [drinking] alcohol can increase blood pressure 15 to 20 points," he says. "And if you start off hypertensive, raising your blood pressure 15 or 20 points probably does as much as double your risk of stroke, so this certainly fits with things we already know."

Small lifestyle changes may have big impact on reducing stroke risk

Making small lifestyle changes could reduce your risk of having a stroke, according to a new study in the American Heart Association journal Stroke.

Researchers assessed stroke risk using the American Heart Association's Life's Simple 7 health factors: be active, control cholesterol, eat a healthy diet, manage blood pressure, maintain a healthy weight, control blood sugar and don't smoke.
"We used the assessment tool to look at stroke risk and found that small differences in health status were associated with large reductions in stroke risk," said Mary Cushman, M.D., M.Sc., senior author and professor of medicine at the University of Vermont in Burlington.
Researchers divided the Life's Simple 7 scores into three categories: zero to four points for inadequate, five to nine points for average, and 10 to 14 points for optimum cardiovascular health.
Researchers found:
- Every one-point increase toward a better score was associated with an 8 percent lower stroke risk.
- Compared to those with inadequate scores, people with optimum scores had a 48 percent lower stroke risk and those with average scores had a 27 percent lower stroke risk.
- A better score was associated with a similar reduced stroke risk in blacks and whites.
While black participants had worse Life's Simple 7 scores than whites, the association of the Life's Simple 7 score with stroke risk was similar in black and white participants. "This highlights the critical importance of improving these health factors since blacks have nearly twice the stroke mortality rates as whites," Cushman said.

Sleep condition linked to sudden heart problems

Sleep apnoea, an illness that causes breathing problems while sleeping, may increase the chances of sudden heart problems. But the overall risk of dying from sudden heart problems is still low.

What do we know already?

Sleep apnoea is when a person stops breathing for 10 seconds or longer, at least five times an hour, while asleep. It’s thought that 1 or 2 in every 100 men aged over 35 in the UK have this condition. Symptoms can include loud snoring, choking, or gasping during sleep, and feeling sleepy during the day, because your sleep has been disturbed.

As well as these symptoms, some studies have shown that sleep apnoea may increase the chances of heart problems. In this new study researchers wanted to see if there was a link between sleep apnoea and sudden death from heart problems, called ‘ sudden cardiac death’. Doctors describe this as an unexpected natural death from heart problems, usually within an hour of a person having symptoms, and which happens to someone without any known heart problems.

The researchers looked at more than 10,000 people who all had a test, called a polysomnogram, to diagnose sleep apnoea between 1987 and 2003. Over an average of five years the researchers recorded how many people in the study died of sudden heart problems.

Can You Reverse Heart Disease?

Imagine that you’ve just left your cardiologist’s office. He’s told you that you have to make some changes. Your blood pressure is way over the limit at 170 over 100 and your LDL cholesterol (that’s the “bad” kind) is hovering right around 200. He conducted an exercise cardiac stress test, putting you on the treadmill and increasing the speed and elevation periodically while monitoring your heart -- and he didn’t like the results.

The diagnosis: coronary artery disease (CAD).

Besides surgery or medication, is there anything you can do to modify the course of CAD? The answer to that is, clearly, yes -- as long as your doctor is on board. Making some simple but significant changes in what you eat, how often you exercise, how much you weigh, and how you manage stress can help to put the brakes on heart disease.

But can you actually reverse heart disease, not just slow it down? The answer to that question is much more controversial. Here are two expert's views.

Yes, You Can!

Dean Ornish, MD, founder and president of the Preventive Medicine Research Institute and clinical professor of medicine at the University of California, San Francisco, says that you absolutely can reverse at least some of the damage of even severe heart disease. Indeed, one of his six best-selling books is titled Dr. Dean Ornish's Program for Reversing Heart Disease.

Are you hooked on fish oil yet?

- All fish oils contain omega-3s, types of polyunsaturated fatty acid which are essential for health.
- Fish such as mackerel, salmon, trout, sardines, pilchards and fresh tuna, which are known as oily fish, are the richest sources.
- Dr Carrie Ruxton, nutritionist for the Health Supplements Information Service, says: ‘There are different types of omega-3 fatty acids, but the key health benefits  are believed to come from the very long chain omega-3s, called docosahexaenoic  acid [DHA] and eicosapentaenoic  acid [EPA].’
- The Food Standards Agency (FSA) recommends we eat a minimum of two portions of fish each week, one of which should be an oily fish (one portion is about 140g). This provides a daily intake of 450mg of EPA and DHA.
- Today many supplements will specify which type they contain and in what concentration.
- EPA and DHA have different roles in the body. Dr Ruxton says: ‘Studies suggest DHA is more important for the brain, retina and infant development, while EPA is more important for vascular health [blood vessels].’
- ‘The difficulty we have in the UK is that two-thirds of people don’t eat oily fish,’ she says. ‘The main source of long chain omega-3s in the diet is oily fish, and if we can’t get them from that, we need to consider a supplement to top up our diet.’

Stroke: Causes and Risk Factors

A stroke, sometimes called a “brain attack,” happens when an artery to the brain becomes blocked or ruptures. As a result, blood flow is cut off to a part of the brain, depriving cells of oxygen and glucose from the blood supply. If the cut-off is brief, brain cells may be stressed but able to recover. But if cells are deprived for more than 3 or 4 minutes, they may die, resulting in permanent damage to the brain. In some cases of stroke, certain functions are lost, but other areas of the brain can learn to do the tasks previously handled by the damaged area.

Two types of stroke exist:

Ischemic stroke: About 80% of strokes are ischemic strokes. This type happens when a blood vessel in the brain develops a clot that cuts off blood flow to cells.

Hemorrhagic stroke: The remaining 20% are hemorrhagic strokes, which happen when a weakened blood vessel in the brain bursts. When the vessel bleeds or hemorrhages suddenly, surrounding brain tissue can become damaged. Hemorrhagic stroke is the most serious type of stroke.

Risk Factors

How do you know if you are at risk for having a stroke? There are two types of risk factors: controllable and uncontrollable. Some stroke risk factors, such as high blood pressure and smoking, can be controlled by medication or lifestyle changes. Other risk factors, such as age and race, cannot be changed.

Blood pressure drug 'fights cancer'

A commonly used blood pressure drug could help fight cancer by opening up blood vessels in solid tumours.
Used beside conventional cancer-fighting drugs, it could improve life expectancy, experts believe.
Following successful testing in mice, doctors plan to give losartan to patients with pancreatic cancer to see if it can tackle this hard-to-treat disease, Nature Communications reports.
Currently, only 5% of pancreatic cancer patients survive for at least 5 years.
This is partly because only one in 10 people with the disease has a tumour that is operable.
Future hope
Investigators at the Massachusetts General Hospital in the US are currently recruiting volunteer patients with inoperable pancreatic cancer to test out the new drug combination of chemotherapy plus losartan.

Top 5 Signs of Deficiency of Calcium

Since calcium is an essential element for bones, a deficiency of calcium affects bones the most severely.

One of the initial symptoms of calcium deficiency is muscle cramps. This sign of deficiency of calcium occurs as the initial alarm towards the decrease of calcium in the body. Muscles ache, especially those of the thighs, arms, and underarms while moving and walking around may be a sign of calcium deficiency.

Another important sign of the deficiency of calcium in the body is insomnia. In many cases, people who do not consume enough calcium in their diet suffer from loss of sleep. In certain cases, it is seen that a person, due to calcium deficiency, may fall asleep, but will not have a satisfactory or deep sleep.

Calcium is also an important constituent for our teeth. Thus, deficiency of calcium in the body affects the teeth as well. Tooth decay is another sign of calcium deficiency in the body. Due to calcium deficiency in childhood, there may be delay in the initial start of tooth formation.

Calcium deficiency results in poor bone density. This can be quite a serious condition for children as it may lead to easy fractures, muscular aches, and spasms, and – in extreme cases – rickets.

Our nails also require calcium in adequate amounts to grow healthy and remain strong. Weak and brittle nails are another important sign of calcium deficiency in the bod

10 Diabetes Diet Myths

"Diabetes diet." Simply hearing these words may be enough to make you feel overwhelmed or frustrated.

Perhaps you have said, or heard someone else express, one of these thoughts:

- Eating too much sugar causes diabetes.
- There are too many rules about choosing foods that are OK in a diabetes diet.
- You have to give up all your favorite foods when you're on a diabetes diet.
- These three statements are all myths about diabetes diets. Take a closer look at these and other myths to find out the facts about diabetes and diet.

Myth 1: Eating Too Much Sugar Causes Diabetes.
How does diabetes happen? The causes are not totally understood. What is known is that simply eating too much sugar is unlikely to cause diabetes. Instead, diabetes begins when something disrupts your body's ability to turn the food you eat into energy.

To understand what happens when you have diabetes, keep these things in mind: Your body breaks down much of the food you eat into glucose, a type of sugar needed to power your cells. A hormone called insulin is made in the pancreas. Insulin helps the cells in the body use glucose for fuel.
