5 Dangers of Excess Abdominal Fat


By Daily Health Post February 27, 2013

By now, most of us are well aware of the health risks that are associated with obesity. But did you know that excess abdominal fat in particular carries its own set of risks? A high waist-to-hip ratio, caused by visceral fat setting up shop inside your abdomen and around your organs, has been associated with these five long-term health issues.

#1 Decreased Lung Function
Last year, a team of Finnish researchers found that a large waist circumference is related to decreased lung volume and function. In comparison with other healthy, non-smoking adults who did not have excess abdominal fat, those who carried more fat performed far more poorly on spirometry (breath measurement) tests.

Over time, this decreased lung function can lead to a narrowing of the airway and ultimately chronic lung diseases like asthma.

#2 Arterial Degeneration
Another 2012 study found a significant correlation between abdominal obesity and high incidence of arthrosclerosis and arterial stiffness. The researchers studied both individuals with abdominal obesity and general obesity, as well as healthy individuals, and discovered that for every 0.1 increase in the waist to height ratio, arterial issues worsened. This tendency was particularly pronounced in people with excess abdominal fat. Arterial degeneration can lead to stroke and various forms of heart disease.

#3 Poor Blood Sugar Regulation
Visceral fat – the type of fat found in people with abdominal obesity – produces a number of hormones that can wreak havoc on your metabolic systems. These hormones can trigger changes to insulin receptors in your body, meaning that insulin starts to become less effective in helping to regulate your blood sugar. This is, of course, one of the major causes of diabetes.

 #4 Dementia and Alzheimer’s Disease
It turns out that what’s going on in your gut can have a big effect on your brain. A 2010 study found that a high waist-to-hip ratio, as well as the presence of abdominal visceral fat in general, is linked with low brain volume. Low brain volume has in turn been linked with general dementia and may also be a contributing factor in Alzheimer’s disease.

#5 High Cholesterol
Visceral fat can be turned into free fatty acids by the body, which results in the production of LDL (also known as “bad”) cholesterol and triglycerides. In addition, the free fatty acids also reduce the body’s level of HDL (also known as “good”) cholesterol. Along with abdominal obesity’s relationship with arterial degeneration, the cholesterol-related effects of excess belly fat are a perfect storm for heart disease, high blood pressure, and stroke.

Where you tend to store your fat is largely dictated by your genes, but if you have excess abdominal fat, there are ways to minimize your risk. According to the experts, exercise is the best way to get rid of that visceral fat, even more so than calorie restriction (although sticking to a healthy diet is always a good idea). Aim for half an hour to an hour of exercise most days of the week, and with determination, you should be able to shrink your belly and your chances of developing any of these long-term health problems.

Surprises found in hunt for environmental links to breast cancer


Tuesday, November 12, 2013
By Kerry Sheridan, AFP

WASHINGTON -- A decade-long research effort to uncover the environmental causes of breast cancer by studying both lab animals and a group of healthy U.S. girls has turned up some surprises, scientists say.
At the center of the investigation are 1,200 school girls who do not have breast cancer, but who have already given scientists important new clues about the possible origins of the disease.

Some risk factors are well understood, including early puberty, later age of childbearing, late onset of menopause, estrogen replacement therapy, drinking alcohol and exposure to radiation.

Advances have also been made in identifying risky gene mutations, but these cases make up a small minority. “Most of breast cancer, particularly in younger women, does not come from family histories,” said Leslie Reinlib, a program director at the National Institute of Environmental Health Sciences. “We have still got 80 percent that has got to be environmental,” said Reinlib, who is part of the Breast Cancer and the Environment Research Program (BCERP) program that has received some US$70 million in funds from the U.S. government since 2003.

Some of its researchers track what is happening in the human population, while others study how carcinogens, pollutants and diet affect the development of the mammary glands and breast tumors in lab mice. The program's primary focus is on puberty because its early onset “is probably one of the best predictors of breast cancer in women,” Reinlib said.

Puberty is a time of rapid growth of the breast tissue. Research on survivors of the Hiroshima atomic bombings in Japan has shown that those exposed in puberty had a higher likelihood of developing breast cancer in adulthood. The 1,200 U.S. girls enrolled in the study at sites in New York City, northern California and the greater Cincinnati, Ohio, area beginning in 2004, when they were between the ages of six and eight.

The aim was to measure the girls' chemical exposures through blood and urine tests, and to learn how environmental exposures affected the onset of puberty and perhaps breast cancer risk later in life. Researchers quickly discovered that their effort to reach girls before puberty had not been entirely successful.

“By age eight, 40 percent were already in puberty,” said Reinlib. “That was a surprising bit of information.” Further research has shown that the girls appear to be entering puberty six to eight months earlier than their peers did in the 1990s.

Obesity an Influencing Factor

A study published last week in the journal Pediatrics on this cohort of girls found that obesity was acting as a primary driver of earlier breast development. Other studies on the girls have focused on chemicals that are known as endocrine disruptors because they are believed to cause either earlier or later breast development.

Initial results showed “for the first time that phthalates, BPA, pesticides are in all the girls they looked at,” said Reinlib. Researchers were taken aback by the pervasiveness of the exposures, but also by the data which appeared to show some plastic chemicals might not be as influential on breast development as some have feared.

“They didn't find much of an association between puberty and phthalates, which are these chemicals that leach out of plastic bottles and Tupperware,” Reinlib said. Another major finding regarded blood chemicals from two nearby groups in Ohio and Kentucky, both drinking water that was apparently contaminated by industrial waste.

Girls in northern Kentucky had blood levels of an industrial chemical — perfluorooctanoic acid (PFOA or C-8) found in Teflon non-stick coating for pans — three times as high as those who drank water from the Ohio River near Cincinnati, where water was filtered with state-of-the-art technology.

“Northern Kentucky did not have granular activated carbon filtration” in their water supply said researcher Susan Pinney, a professor at the University of Cincinnati School of Medicine. “In 2012 they put it in after they learned of our preliminary results.” Families were also notified of their daughters' blood levels, she said.

The chemicals can linger in the body for years. Researchers were dismayed to learn that the longer the girls spent breastfeeding as infants — typically touted for its health benefits — the higher their PFOA levels compared to girls who were fed formula.

What cannot be studied in the girls is tried on lab mice, who in one experiment are being fed high-fat diets and exposed to a potent carcinogen to see how the two interact. Mammary tumors develop much faster in the high-fat diet group, said scientist Richard Schwartz of the Department of Microbiology and Molecular Genetics at Michigan State University.

Fat mice have more blood supply in the mammary glands, higher inflammation levels and display changes in the immune system. Follow-up studies suggest that cancer risk stays high even if mice are fed high-fat diets in puberty and switched to low-fat diets in adulthood, he told AFP.

“The damage is already done,” he said. “Does this mean that humans are at risk the same way? We don't know that with certainty.” But the findings do reinforce the advice that people often hear regarding how to maintain good health — avoid fatty foods, maintain a normal weight and reduce chemical exposures wherever possible, experts say.

Breast cancer is the most common cancer in women globally and took 508,000 lives in 2011, according to the World Health Organization.

Best Foods To Prevent A Stroke (And What To Avoid)


Posted: 23/12/2013 11:10 GMT  |  Updated: 23/12/2013 11:30 GMT

Diet can be an instrumental factor in preventing or hastening the onset of a stroke.

Alice Mackintosh, nutritionist at The Food Doctor said: "Though genetic predisposition plays a part in the development of cardiovascular issues, it has been hypothesized that most cases of stroke can be prevented by living a healthy lifestyle, thereby reducing risks of further compromising heart health. Factors that can make one more susceptible to strokes include: smoking, stress, low physical activity, a high saturated fat diet, high cholesterol levels, uncontrolled diabetes and high blood pressure."

What healthy diet changes can you make in 2014, and what should you look at avoiding? We asked three experts for their advice.

Liver-supporting foods
You may ask what this has to do with your heart, but the liver is where cholesterol is actually made. Nutritionist Karen Poole says this includes onion, garlic, cabbage, fennel, broccoli, watercress, celery, radish, rocket, chicory, garlic, artichoke, and spinach into your weekly holiday diet.

"The liver initially makes cholesterol and then breaks it down when it has performed its tasks and a healthy liver will function more efficiently and is therefore, essential for effective overall blood cholesterol regulation. The liver will no doubt take a bashing over the festive season so make sure to give it some TLC."

Cut out pastries and fatty meats
Recently findings have revealed that while all saturated fats are not evil when it comes to heart disease and strokes, trans fats should be avoided as much as possible. This - sad to say - will include all the things we like. Yvonne McMeel, resident nutritionist at Urban Retreat says these are "heavily processed food; meat pies, sausages and fatty cuts of meat, lard, cream, hard cheese, cakes and biscuits."

Omega-3
"Cholesterol balancing omega 3 fats has been shown to significantly reduce the risks of strokes," says Alice. "In particular, omega-3 fatty acids which can be obtained from fatty fish (e.g. salmon, herring and mackerel), walnuts, hempseed and even green leafy veg have stroke protective properties. by inducing vasodilation of blood vessels, they reduce the risk of blood clots whilst also decreasing platelet deposition in the arteries and veins, leading to a reduction of plaque build-up that can lead to a rise in blood pressure."

B12, folic acid and B2
"High levels of homocysteine, a byproduct of regular protein metabolism produced daily by everyone, is becoming widely recognised as an indicator for potential stroke and CVD issues," advises Karen.

"The good news is by increasing your intake of B12 ,B2 and folic acid you can affect your homocysteine levels and reduce the risk of cholesterol oxidisation (cholesterol is most dangerous when it is oxidised ) and subsequent plaque formation. Almonds, avocado, eggs, barley, wholegrains, broccoli, herring, salmon, sardines, beans, yeast, soy beans, green leafy vegetables, sprouts, endive and lentils.

Fresh fruit and vegetables
We already know fresh fruit and veg is good for us, but when it comes to stroke prevention, Yvonne reveals it has a crucial role. "Vegetables are a good source of potassium which is the natural antagonist of sodium; it will help reduce blood pressure."

Both are packed with antioxidants which support the body's healing process. When it doubt, go for fruit and vegetables with the darkest colours. Alice adds: "Super foods such as goji berries, hempseed and acai can also protect against plaque build-up in arteries and should be consumed with regularity."

Oats
These play a key role in lowering cholesterol. "Beta glucans, present in oats, can help to lower cholesterol levels," says Karen, "as they bind to dietary fats and carry them out of the body before they can be digested and absorbed."

Garlic
"Fresh garlic contains several compounds, the most important of which is allicin," says Yvonne. "This has been shown to protect against high blood pressure, infections, indigestion amongst other conditions. Several studies have shown that it can reduce harmful cholesterol by about 12 per cent, and inhibits new growth of plaque in the arteries that can lead to heart attack or stroke. Garlic may also inhibit the growth of cancer cells and strengthen the immune system."

Do's And Don'ts Checklist
  • DO take part in physical activity (30mins 5 days per week)
  • DO eat foods rich in folate, such as beans and pulses, green leafy veg and eggs, magnesium and potassium
  • DO build relaxation time into each day to reduce stress as cortisol release induces vasoconstriction (arteries contracting). Just 20 minutes per day could make a difference
  • DO keep to a healthy weight especially around the middle as visceral fat can release substances that disrupt hormone regulation and may raise blood pressure
  • DON'T continue to smoke
  • DON'T drink too much (no more than 2 drinks per day)

Bahan-Bahan Ini Berbahaya Kalau Terkena Kulit


Vemale.com - Tidak ada produk skincare yang benar-benar aman sekalipun berlabel natural. Kulit wanita itu unik, dan terkadang sensitif terhadap sebagian bahan aktif yang terkandung di dalam produk skincare.

Agar Anda bisa lebih berhati-hati, ketahui beberapa bahan-bahan yang bisa menimbulkan alergi, iritasi, dan mungkin penyakit atau kerusakan kulit.

Benzoyl peroxide
Banyak produk skincare yang mengandung bahan ini, khususnya produk yang menyembuhkan jerawat. Tetapi Anda tetap harus berhati-hati saat menggunakan produk yang satu ini. Susan Jeske, seorang ahli kulit, seperti dikutip dari allwomenstalk mengatakan bahwa Benzoyl peroxide mengandung zat karsinogen yang tak hanya dapat menyebabkan kulit keracunan, atau mengalami kerusakan sel, tetapi juga dapat memicu kanker kulit.

Triclosan
Mengapa Anda tak sebaiknya menggunakan produk berbahan triclosan untuk kulit? Yeap, triclosan ternyata berhubungan erat dengan beberapa kerugian seperti melemahkan sistem immune tubuh, pertumbuhan abnormal, serta cacat pada janin.

Terdengar seperti bahan yang familiar, triclosan memang biasa dipakai dalam produk antibakteri, pasta gigi dan bahkan juga makeup. Triclosan mungkin dapat membasmi bakteri, tetapi di satu sisi, ia juga menimbulkan kerugian bagi Anda.

Zinc
Mendengar kata zinc, Anda mungkin berpikir bahwa itu adalah mineral baik yang sering ditemukan pada makanan. Mineral ini dikembangkan menjadi zinc oxide yang digunakan untuk bahan skin care dan tabir surya oleh para peneliti. Namun sayangnya Universitas kedokteran Missouri menemukan fakta bahwa partikel nano zinc oxide ini dapat menyebabkan kanker kulit dan menutup pori-pori.

EPA
Seringkali ditemukan pada parfum, EPA adalah bahan berbahaya yang dapat menyebabkan kegagalan pernafasan, penyakit ginjal serta mempengaruhi sel syaraf.

Petroleum
Tidak sedikit lho skincare yang menggunakan bahan ini di dalam produknya. Misalnya saja produk perawatan rambut, makeup, pasta gigi, dan bahkan dalam sebagian besar baju Anda. Kandungan petroleum ini berbahaya karena dapat menyebabkan pori-pori tertutup, memicu munculnya jerawat hingga kanker kulit.

Acetone
Bahan berbahaya yang terkandung di dalam acetone adalah tingginya resiko merusak liver, kulit, serta saluran pernafasan. Disarankan untuk Anda yang gemar memulas kuku lebih baik menggunakan produk non acetone.

Klorin
Bahan ini biasanya digunakan untuk membersihkan dan menjernihkan kolam serta membuat air kolam tetap dingin. Klorin dapat memicu alergi, diabetes, tekanan darah tinggi, asma dan banyak penyakit lain yang dapat membahayakan tubuh.

Mencegah reaksi negatif klorin, disarankan agar Anda mandi setiap habis berenang dan memastikan seluruh tubuh Anda bersih.

Karena bahan-bahan tersebut ada di sekitar Anda dan mungkin terkandung pada produk-produk yang Anda gunakan, lebih berhati-hati ya ladies saat menggunakan produk tersebut. Akan lebih baik lagi jika Anda bisa mengganti dengan produk yang punya bahan lebih aman.

Clean out your liver


BY Tamra Mercieca

Need to clear your skin, improve digestion or boost your energy? Keeping your liver healthy could be the key.

Our liver's main function is to naturally detox the body. It is our internal cleaner, which, given the right support, has the ability to keep the body clear of the junk which can cause illness.

The liver is our second-largest organ (only the skin is bigger) and therefore one of the most important. If the body was an automobile, the liver would be its engine. It does hundreds of things to make sure it runs smoothly, playing a vital role in regulating fat and balancing our hormones, digestion and circulation.

But medical herbalist Dominique Finney says the liver's main job is to get rid of foreign substances. "Anything that enters the bloodstream is filtered through the liver to ensure that quality nutrients go to the organs, while any excess is removed."

Acupuncturist Adam Davidson says from a Chinese medicine perspective, the liver controls the flow of qi (energy) through the body. "It also 'rules' the tendons and stores the blood which nourishes the eyes and nails. It also influences our digestion and menstruation."

Blocked liver
Indulging in alcohol or junk food may be fun at the time, but it will make your liver work extra hard. All the alcohol, processed foods and toxic chemical residue we're exposed to get caught in the liver. If we are exposed to too much junk, our liver starts to resemble a dirty, wet sponge that needs to be wrung out.

Finney says when the liver becomes congested it will not filter blood optimally. "It can become blocked, fatty or bloated. It will then contribute to high cholesterol and lowered synthesis of nutrients and new cells, compromising your health."

This is why many alcoholics have liver failure: the organ is never given time to regenerate.

The liver is behind the ribs in the upper right-hand part of the abdomen. We can only survive one or two days if it shuts down. That said, the liver can function even when up to 75 per cent of it is diseased, as it has the amazing ability to create new liver tissue.

More than 2000 Australians die from liver diseases each year. The first signs of a struggling liver include headaches; fatigue; depression; poor concentration; mood swings; allergies; rashes; red, itchy eyes; food sensitivities; sore and stiff sides or even a bitter taste in the mouth.

Should you detox?
Dietitian Emilie Isles doesn't encourage detox plans because the liver is always working to detoxify the body. "You're better off improving eating habits to boost liver function instead of paying for gimmicky plans or following restrictive diets. We need to get back in touch with real food and ensure we understand what nutrients we need."

Isles recommends keeping your diet relatively low in fat, consuming five serves of vegetables and two serves of fruit per day and keeping alcohol to a minimum.

Davidson agrees. "I'm not a fan of detoxing, unless it's a severe case, and then only under the supervision of a qualified practitioner."

Finney says: "Detoxing is a natural bodily process that occurs every night when you sleep and each time you are sick. You need nothing to detox properly except yourself, fresh water, a place to rest peacefully and some silence."

Liver helpers
While the key to a healthy liver is maintaining harmony and balance, Davidson says there are some foods and supplements that will help the liver do its work better.

"Ginger, most dark green leafy vegetables, beetroot and mint will all help the free flow of our qi. The most common traditional Chinese medicine herbal formula for liver ailments is called xiao yao san, and can be made by a qualified practitioner or bought in pill form."

Liver cleansers
Carrots: High in beta-carotene, they help regulate blood-sugar levels, while reducing inflammation in the body and are a good energy food.

Milk thistle: Contains an antioxidant that acts as a toxin blocker. Capsules can be taken daily for an extended period to repair the liver.

Black walnuts: Help to eliminate toxins. Finney says it can be taken in powder or capsule form, for 30 days, after which you should give it a rest.

Lemons: Cleanse not only the liver, but also the gallbladder, kidneys, digestive tract and lungs.

Garlic: Helps strengthen and cleanse the blood, while giving the liver and kidneys a spring clean.

Dandelion tea: Dandelion has been used for centuries. It is a blood purifier and antioxidant and is recommended for those with liver complaints.

Beetroot juice: Contains a chemical called betaine that stimulates the liver cells and protects the liver and bile ducts.

Get plenty of sleep: Also have infrared saunas, indulge in lymphatic massages and drink lots of filtered water.
