Higher intakes of the B vitamins thiamine and riboflavin from the diet may reduce the incidence of premenstrual syndrome (PMS) by about 35 percent, suggest new findings. According to a new paper published in the American Journal of Clinical Nutrition, the link between B vitamins and PMS is biologically plausible since B vitamins such as thiamine and riboflavin are known to play important roles in the synthesis of various neurotransmitters involved in PMS.
While most women experience mild emotional or physical premenstrual symptoms, as many as 8-20 per cent of women experience symptoms severe enough to meet the definition of premenstrual syndrome, which can substantially interfere with daily activities and relationships. The new study, performed by researchers from the University of Massachusetts, Harvard, and the University of Iowa, indicates that increase intakes of certain B vitamins from food sources may help reduce the incidence of PMS.
Using data from 1,057 women with PMS and 1,968 women without PMS participating in the Nurses' Health Study II cohort, the researchers found that women with the highest average intakes of riboflavin two to four years prior to diagnosis were associated with a 35 percent lower incidence of PMS than women with the lowest average intakes. On the other hand, the researchers did not observe any benefits with other B vitamins, including niacin, folate, B6, and B12. In addition, supplemental intakes of these vitamins was not linked to PMS incidence, they added. “We observed a significantly lower risk of PMS in women with high intakes of thiamine and riboflavin from food sources only,” wrote the researchers. “Further research is needed to evaluate the effects of B vitamins in the development of premenstrual syndrome.”
Beyond the B vitamins, there is also some evidence for the potential of a diet rich in calcium and vitamin D to lower the risk of developing PMS, a condition that affects up to a fifth of all women. According to a study published in 2005 in the Archives of Internal Medicine (Vol. 165, pp1246-1252), researchers from the University of Massachusetts and GlaxoSmithKline reported for the first time that calcium and vitamin D may help prevent the initial development of PMS.

About one in seven Britons feels under extreme stress, a survey suggests.We can reasonably conclude that these numbers will be similar right here in Australia. Experts say stress raises blood pressure, putting people at greater risk of stroke. A poor diet and lack of exercise also contribute to the chances of suffering a stroke. Stroke is the third leading cause of death in the United States. Over 143,579 people die each year from stroke in the United States. Stroke is the leading cause of serious, long-term disability in the United States. Each year, about 795,000 people suffer a stroke. About 600,000 of these are first attacks, and 185,000 are recurrent attacks. Almost one in five women and one in 10 men feel their stress levels are out of control, according to the poll of 2,000 people in Britain.
The survey, by the Stroke Association and the engineering company Siemens, found almost a fifth of people said they took no exercise. A similar number said they exercised for 30 minutes once a week. More than a quarter of people aged 45 to 54 said they never exercised, despite suffering the highest stress levels. Almost half said they were under more than “moderate stress”. Overall, 40 per cent of those surveyed said they were unaware of the link between exercise and lowering the risk of stroke.
James Beeby, of the Stroke Association, said: “The research is incredibly worrying and emphasises the need for people to be aware of the dangers of stroke. “It’s imperative that people take regular exercise and modify their diet to reduce the risk of suffering a stroke.” Siemens sponsors the British rowing team and provides some funding for the Stroke Association’s Stroke for Stroke campaign. Andreas Goss, the chief executive of Siemens in the UK, said: “Contrary to popular belief, stroke can affect people of any age.”

Individuals who drink three glasses of milk a day decrease their risk of cardiovascular disease by 18 percent, according to new research published in the American Journal of Clinical Nutrition.Researchers at Wageningen University and Harvard University examined 17 studies from the United States, Europe and Japan and found no link between the consumption of regular or low fat dairy and any increased risk of heart disease, stroke or total mortality. “Milk and dairy are the most nutritious and healthy foods available and loaded with naturally occurring nutrients, such as calcium, potassium and protein, to name a few,” said Cindy Schweitzer, technical director of the Global Dairy Platform. “It's about going back to the basics; maintaining a healthy lifestyle doesn't have to be a scientific equation.”
Schweitzer said during the past three decades as research sought to understand influencers of cardiovascular disease, simplified dietary advice including consuming only low fat dairy products emerged. However, in 2010 alone, a significant amount of new research was published from all over the world, supporting the health benefits of dairy. From dispelling the myth that dairy causes heart disease, to revealing dairy's weight loss-benefits, the following is a roundup of select dairy research conducted in 2010:
- U.S. researchers examined 21 studies that included data from nearly 350,000 and concluded that dietary intakes of saturated fats are not associated with increases in the risk of either coronary heart disease or cardiovascular disease. The study was published in the American Journal of Clinical Nutrition.
- A study published in the American Journal of Epidemiology examined 23,366 Swedish men and revealed that intakes of calcium above the recommended daily levels may reduce the risk of mortality from heart disease and cancer by 25 percent.
- An Australian study published in the European Journal of Clinical Nutrition concluded that overall intake of dairy products was not associated with mortality. The 16-year prospective study of 1,529 Australian adults found that people who ate the most full-fat dairy had a 69-percent lower risk of cardiovascular death than those who ate the least.
- A Danish study published in Physiology & Behavior concluded that an inadequate calcium intake during an energy restricted weight-loss program may trigger hunger and impair compliance to the diet.
- An Israeli study published in the American Journal of Clinical Nutrition showed that a higher dairy calcium intake is related to greater diet-induced weight loss. The study sampled more than 300 overweight men and women during two years and found those with the highest dairy calcium intake lost 38-percent more weight than those with the lowest dairy calcium intake.
The amount of dairy recommended per day varies by country and is generally based on nutrition needs and food availability. “In the US and some European countries, three servings of dairy foods are recommended daily, said Dr. Schweitzer.”
Apples could become the next fish when it comes to boosting health.
In March 2005 Cornell University scientists discovered that phytochemicals in apples could help prevent breast cancer, found in a mouse study. Study author Rui Hai Lui concluded eating apples “may be an effective strategy for cancer protection” Studies also suggest that apples can thwart lung, prostate, pancreatic and other digestive cancers.
Quercitin found in apples might even prevent lung damage in smokers, found by UCLA researchers and published May 2008. Dr. Zuo-Feng Zhang, a researcher at UCLA's Jonsson Cancer Center and a professor of public health and epidemiology. “The findings were especially interesting because tobacco smoking is the major risk factor for lung cancer. The naturally occurring chemicals may be working to reduce the damage caused by smoking.”
The health benefits of apples also extend to the brain. A study underwritten by the apple industry found that mice with Alzheimer's disease and even normal mice experienced memory improvement from receiving apple juice concentrate in their water. Two to 3 glasses of apple juice a day should be enough and it's important to combine apples with an otherwise balanced diet.
Professor Thomas Shea who conducted the study starting in 2002 says mice that drank too much apple juice “became bloated and lethargic”, negating the positive effects of apple juice for boosting memory.
Pectin in apples and other fruit may play a key role in lowering bad cholesterol, shown in several observational studies. Apples are also high in soluble fiber. The American Heart Association recommends soluble and insoluble fiber intake daily as part of a heart healthy diet. Apple pulp is a soluble and apple skin is an insoluble fiber. The Apple Association also published a study May 2008 suggesting that apple juice antioxidants might prevent atherosclerosis, found in a rodent study and published in Molecular Nutrition & Food Research. Additional benefits include reducing the chances of metabolic syndrome that leads to diabetes and heart disease, reported by the U.S. Apple Association.
This year, University of Illinois at Urbana-Champaign published findings that soluble fiber increased production of the anti-inflammatory protein called interleukin-4. The amount of soluble fiber needed to keep infection at bay – for instance from eating apples – is obtainable and not pharmaceutical. For the study researchers used citrus based pectin.
According to Gregory Freund, a professor in the University of Illinois' College of Medicine and a faculty member in the College of Agriculture, Consumer and Environmental Sciences' Division of Nutritional Sciences, “It's possible that supplementing a high-fat diet with soluble fiber could reduce the negative effects of a high fat diet, “even delaying the onset of diabetes.” Apples are an excellent source of soluble and insoluble fiber, making them an especially appealing addition to the diet.
Apples are not a panacea that can fight disease, but they do have a wide array of health benefit. It's important to eat a variety of fruits and vegetables throughout the day. Added to a balanced, nutritious and heart healthy diet, apples might rival fish for their health benefits.
