    7 Health Reasons to Hydrate---How Water and Health Are Connected

    Brain Staying hydrated keeps your memory sharp, your mood stable and your motivation intact. When you're well-hydrated, you can also think through a problem more easily. Researchers hypothesize that not having enough water could reduce oxygen flow to the brain or temporarily shrink neurons-or being thirsty could simply distract you.

    Mouth Water keeps your throat and lips moist and prevents your mouth from feeling dry. Dry mouth can cause bad breath and/or an unpleasant taste-and can even promote cavities.

    Heart Dehydration lowers your blood volume, so your heart must work harder to pump the reduced amount of blood and get enough oxygen to your cells, which makes everyday activities like walking up stairs-as well as exercise-more difficult.

    Bloodstream Your body releases heat by expanding blood vessels close to the skin's surface (this is why your face gets red during exercise), resulting in more blood flow and more heat dissipated into the air. When you're dehydrated, however, it takes a higher environmental temperature to trigger blood vessels to widen, so you stay hotter.

    Limbs When you're well hydrated, the water inside and outside the cells of contracting muscles provides adequate nutrients and removes waste efficiently so you perform better. Water is also important for lubricating joints. Contrary to popular belief, muscle cramps do not appear to be related to dehydration, but, instead, to muscle fatigue, according to Sam Cheuvront, Ph.D., an exercise physiologist for the U.S. Army Research Institute of Environmental Medicine.

    Skin When a person is severely dehydrated, skin is less elastic. This is different than dry skin, which is usually the result of soap, hot water and exposure to dry air. And, no, unfortunately, drinking lots of water won't prevent wrinkles.

    Kidneys Your kidneys need water to filter waste from the blood and excrete it in urine. Keeping hydrated may also help prevent urinary tract infections and kidney stones. If you are severely dehydrated, your kidneys may stop working, causing toxins to build up in your body.

    To eat or not to eat egg, that is the question


    For years, we grew up with the knowledge that eating egg yolks increased one's risk of heart attack and stroke.

    But sometime in the 1990s, this idea was labeled as a "myth" by the Health Professionals Follow-up Study and the Nurse's Health Study. Both researches stated that consuming one egg per day had little or no impact on cardiovascular health. The world rejoiced and proceeded to have their omelets and sunny-side ups.

    Today, the tables have turned 180-degrees.


    Decreases blood flow to vital organs

    Dr. J. David Spence of the Robarts Research Institute in London has data to show that lifelong consumption of egg yolks increased the development of blocked arteries in patients at risk of heart disease.

    The results showed the formation of blood vessel plaques measuring 125 mm2 for patients consuming less than 2 eggs per week. The plaque size increased to 132 mm2 for subjects who ate 3 or more egg yolks per week.

    The vascular plaques are responsible for decreasing the blood flow to vital organs like the heart and the brain. Continuous increase in diameter of these plaques will eventually lead to total blockage of blood flow causing a heart attack or a stroke.

    Dr. Spence further points out that a single egg yolk contains 275 mg of cholesterol, which is more than the recommended daily allowance for cholesterol of 200 mg a day.



    Dispute

    The Egg Nutrition Center in the U.S. is not impressed by these results. Their executive director, Dr. Mitch Kanter says the study "is not well done" He says the subjects were all elderly and were naturally at higher risk of cardiovascular disease.

    Dr. Spence expected this criticism from the egg Industry and replies, " Every time a paper like this comes out … the egg marketers come out with their own statements. No wonder the public is confused."

    This debate will go on and on with no end in sight.

    The "egg magnates" have millions to lose if this latest data proves true while Dr. Spence has nothing to gain but the good health and well-being of his patients.

    What else can be said but … "let the buyer beware."

    Just half-hour jog may make you smarter 'by boosting energy levels in brain'

    London, March 2 (ANI): It is well known that exercise increases our fitness levels by making the muscles more resistant to fatigue.

    Past research has found exercise spurs the birth of new mitochondria - structures in the cells that produce the body's energy - in the muscles.
    This process increases your fitness endurance while reducing the risk of obesity.
    Now, a team from the University of South Carolina have revealed that a regular gym session could sharpen the mind in exactly the same way.
    They have found that regular treadmill sessions also give a boost to the cell's powerhouses in the brain.
    Research leader, Dr Mark Davis said this energy boost helped the brain to work faster and more efficiently.
    "The evidence is accumulating rapidly that exercise keeps the brain younger," the Daily Mail quoted Dr Davis as telling Scientific American.
    In the short term he said this could reduce mental fatigue and sharpen your thinking in between gym sessions.
    He added that building up a large reservoir of mitochondria in the brain could also create a 'buffer' against age-related brain diseases such as Alzheimer's.he researchers came to their conclusions after a study, published in The Journal of Applied Physiology, on a group of mice.
    Half of the mice were exercised on a small treadmill for half an hour a day while the other half were left to lounge in their cages.
    Unsurprisingly they found after eight weeks that the running mice could exercise for 126 minutes before they tired, while the sedentary mice could only manage 74 minutes.
    However, tissue samples revealed the running mice also had a surge in mitochondrial development in the brain, with evidence of both new mitochrondria and increased signaling between the brain cells.
    Dr Davis said although it was an animal study, it was reasonable to assume the same process 'occurs in human brains'.
    He added that a 30-minute jog was the human equivalent to the workout that the mice completed. (ANI)

    World Renown Heart Surgeon Speaks Out On What Really Causes Heart Disease

    A heart surgeon who's performed 5000 open heart surgeries thinks the medical community got it wrong on what causes heart disease. It's not high cholesterol in the blood. That's an indirect cause. The real cause of heart disease is chronic inflammation. Why does Dr. Lundell think this?

    "While you may not be able to see it, rest assured it is there. I saw it in over 5,000 surgical patients spanning 25 years who all shared one common denominator -- inflammation in their arteries."

    Please read the article if you or someone you know has heart disease. The 2 major causes of inflammation are, an imbalance of omega 6 to omega 3 fatty acids and too much sugar in the diet.

    "Blood sugar is controlled in a very narrow range. Extra sugar molecules attach to a variety of proteins that in turn injure the blood vessel wall. This repeated injury to the blood vessel wall sets off inflammation. When you spike your blood sugar level several times a day, every day, it is exactly like taking sandpaper to the inside of your delicate blood vessels."

    OMEGA-3 FATTY ACIDS

    There are many health benefits of omega-3 fatty acids. Research shows strong evidence that the omega-3s EPA and DHA can boost heart health and lower triglycerides. And there are studies showing that omega-3 fatty acids may help with other conditions -- rheumatoid arthritis, depression, and many more.


    Just what are omega-3 fatty acids exactly? How much do you need? And what do all those abbreviations -- EPA, DHA, and ALA -- really mean?

    Here's a rundown of the essential omega-3 facts you need to know.


    Omega-3 Fatty Acids: Basics


    • Omega-3 fatty acids are considered essential fatty acids. We need them for our bodies to work normally. Because essential fatty acids (ALA,DHA,EPA) are not made in the body or are inefficiently converted from ALA to EPA and DHA, we need to get them from our diet .
    • Omega-3s have a number of health benefits. Omega-3s are thought to play an important role in reducing inflammation throughout the body -- in the blood vessels, the joints, and elsewhere. However, omega-3 supplements (EPA/DHA) may cause the blood to thin and cause excess bleeding, particularly in people taking anticoagulant drugs.
    • There are several types of omega-3 fatty acids. Two crucial ones -- EPA and DHA -- are primarily found in certain fish. Plants like flax contain ALA, an omega-3 fatty acid that is partially converted into DHA and EPA in the body. Algae oil often provides only DHA.
    • Experts say that DHA and EPA -- from fish and fish oil -- have better established health benefits than ALA. DHA and EPA are found together only in fatty fish and algae. DHA can also be found on its own in algae, while flaxseed and plant sources of omega-3s provide ALA -- a precursor to EPA and DHA, and a source of energy.



    Omega-3 Fatty Acids: Benefits


    • Blood fat [triglycerides]. According to a number of studies, fish oil supplements can also cut elevated triglyceride levels. Having high levels of this blood fat is a risk factor for heart disease. DHA alone has also been shown to lower triglycerides.
    • Cardiovascular health. Omega-3 fatty acids appear to lower the overall risk of death from heart disease. Fish oil may reduce arrhythmias, and people who take fish oil supplements after a heart attack cut their risk of having another heart attack. Eating fish once or twice a week seems to significantly lower the risk of stroke.
    • Rheumatoid arthritis. A number of studies have found that fish oil supplements [EPA+DHA] significantly reduced stiffness and joint pain. Omega-3 supplements also seem to boost the effectiveness of anti-inflammatory drugs.
    • Depression. Researchers have found that cultures that eat foods with high levels of omega-3s have lower levels of depression. Fish oil also seems to boost the effects of antidepressants. Fish oil may help reduce the depressive symptoms of bipolar disorder.
    • Prenatal health. Studies show that EPA and DHA supplementation during pregnancy boost the health of pregnant women and the development of their children. DHA appears to be important for visual and neurological development in infants.
    • Asthma. Evidence suggests that a diet high in omega 3s reduces inflammation, a key component in asthma. However, more studies are needed to show if fish oil supplements improve lung function or reduce the amount of medication a person needs to control their disease.
    • ADHD. Some studies show that fish oil can reduce the symptoms of ADHD in some children and improve their cognitive function. However, more research is needed in this area, and omega-3 supplements as a primary treatment for this disorder are not supported by research.
    • Alzheimer's disease and dementia. The evidence is preliminary, but some research suggests that omega-3s may help protect against Alzheimer's disease and dementia. Recent studies have also evaluated whether the omega-3 supplement DHA can slow the decline seen in those with Alzheimer's dementia or in age-associated memory impairment. One recent study showed that DHA can be a beneficial supplement and may have a positive effect on gradual memory loss associated with aging. However, more research needs to be done.



    Omega-3 Fatty Acids: Omega-3s and Omega-6s


    • You may have heard about the importance of having a healthy balance of omega-3s with another fatty acid, omega-6s. Omega-6s are found in many oils, meats, and processed foods.
    • Many experts believe that most people in the U.S. are eating far too many omega-6s and far too few omega-3 fatty acids. They argue that this imbalance may be causing many chronic diseases.
    • However, other experts disagree. They don't believe the ratio of omega-6s to omega-3s is actually significant. They also argue that the health benefits of omega-6s are being ignored.
    • For now, the full implications aren't clear. But the bottom line is simple. Whether the ratio turns out to matter or not, increasing your intake of omega-3 fatty acids is still a good thing.



    Omega-3 Fatty Acids: Food Sources


    • When possible, try to get omega-3 fatty acids from foods rather than supplements.
    • Fish high in DHA and EPA omega-3 fatty acids include anchovies, bluefish, herring, mackerel, salmon (wild has more omega-3s than farmed), sardines, sturgeon, lake trout, and tuna. Many experts recommend eating these fish two to three times a week.
    • Good food sources of ALA -- which is converted into omega-3 fatty acids in the body -- include walnuts, flax and flaxseed oil, canola oil, olive oil, and soybean oil.
    • While foods containing omega-3 fatty acids have health benefits, some -- like oils and nuts -- can be high in calories. So eat them in moderation.



    Omega-3 Fatty Acids: Supplements


    • If you decide to use a supplement, discuss this treatment with your doctor first to make sure you are getting the benefits you need.
    • Experts usually recommend 1 gram (1,000 milligrams) of DHA and EPA combined from fish oil daily for those with heart disease. People with certain health conditions may take doses of up to 4 grams a day -- but only under a doctor's supervision.
    • The most common side effect from fish oil is indigestion and gas. Getting a supplement with an enteric coating might help.
    • In high doses -- 3 grams and above -- omega-3 supplements (EPA/DHA) can increase the risk of bleeding. People with bleeding conditions -- or who take medicines that could increase bleeding, like Coumadin, Plavix, Effient, Brilinta, and some painkillers -- should talk to a doctor before using any omega-3 supplements. Bleeding-related complications are separate effects for EPA and DHA. DHA has not been associated with bleeding problems.



    Omega-3 Fatty Acids: Tips


    • Choose the right fish. While eating more fatty fish is a good idea, some are more likely to have higher levels of mercury, PCBs, or other toxins. These include wild swordfish, tilefish, and shark. Farm-raised fish of any type may also have higher levels of contaminants. Children and pregnant women should avoid these fish entirely. Everyone else should eat no more than 7 ounces of these fish a week. Smaller fish like wild trout and wild salmon are safer.
    • Consider eating more free-range poultry and beef. Free-range animals have much higher levels of omega-3s than typical, grain-fed animals.
    • Consider a supplement like fish oil capsules or algae oil. Fish oil contains both EPA and DHA. Algae oil contains DHA and may be a good option for those not tolerant to fish or for vegetarians.
    • Talk to your doctor before using a supplement. Before you start using any supplement, you should always talk it over with your doctor. He or she may have specific recommendations -- or warnings -- depending on your health and the other medicines you take.

    A Misleading Vitamin D3 and Influenza Study

    There was an article that came out in the October 3, 2012 issue of the Journal of the American Medical Association titled:
    Effect of Vitamin D3 Supplementation on Upper Respiratory Tract Infections in Healthy Adults: The VIDARIS Randomized Controlled Trial

    This study found that vitamin D3 provided no protection from the flu. The sample size is 322 subjects. One group was given Vitamin D3 and the other group given a placebo. Unfortunately, the study chose a lousy group of subjects and here's why:

    1) 163 subjects did not get a flu vaccine (This is excellent.), but 159 did get a flu vaccine (lousy experimental design). The flu vaccine is an interference, an extra variable that should not have been introduced since it does the same thing as Vitamin D3.

    2) These are health workers and only 125 of them did not have any exposure to patients (sick people). This is another variable that didn't need to be in the study, since health workers are exposed to the flu virus at a much higher rate than the average person.

    3) Finally, 241 out of 322 of the test subjects were female, so the study is heavily skewed towards females and it may not accurately reflect how males respond to Vitamin D3

    I would therefore urge everyone to continue taking Vitamin D3 for colds and the flu since an earlier Japanese study of children found that it did cut the incidence of the flu in half. (Urashima et al., Am. J. Clin. Nutr. 2010, 91: 1255-60)

    Megavitamin Arthritis Treatment

    I found this link in a book review discussion about arthritis treatments.
    THE COMMON FORM OF JOINT DYSFUNCTION

    This is a 1949 study by a Dr. William Kaufman on the use of niacinamide (vitamin B3) in the treatment of arthritis. It's a remarkable study if the results are true. Dr. Kaufman treats patients with arthritis using about 900mg niacinamide/day and the patients see tremendous improvement in joint mobility and alleviation of pain in as little as 100 days. Eleven case histories are listed in this study.

    "CASE B. No.147, female, age 61, housewife, married.

    She has had joint discomfort for many years, and moderate deformities of the fingers for at least 10 years. Six to seven years ago she first noticed severe pain in her hip joints. Her knees are very stiff. All her life she has had curvature of the spine, and has had a good deal of pain in the back. Recently she has had increased fatigability and insomnia.

    Physical Examination: She looks older than her stated age. B.P. 140/80. Wt. 159 ½ lbs.
    Ht. 65 inches. She has tenderness on digital pressure over the sternum, medial epicondyles, iliac crest, trochanter, styloid process of the radius, sacroiliac joints. Marked kyphoscoliosis is noted. Her tongue shows evidences of infiltration and atrophy of papillae. The edge of the liver, which is one finger's breadth below the rib margin in the right mid-clavicular line on deep inspiration, is tender to palpation. Bony prominences of the lower extremities are hyperpallesthetic to the tuning fork. Tickle sense is absent. Plantar dysesthesia is present.
    .
    .
    .

    Thus, in a period of almost two years, this patient's Joint Range Index rose from 68.2 (severe joint dysfunction) to 92.8 (slight joint dysfunction). It is anticipated that with continuously adequate niacinamide therapy, she will in time achieve a Joint Range Index of 96-100 (no joint dysfunction)."

    Boron and Arthritis

    Is Boron deficiency the cause of arthritis? In countries with high boron content in the soil (and hence the food), the incidence of arthritis is low; in countries with low boron consumption, there is much arthritis.

    Jamaica: <1 mg estimated intake of boron : 70% of the population has arthritis
    Mauritius: <1 mg estimated intake of boron: 50% of the population has arthritis
    USA/Australia: 1-2 mg intake of boron: 20% has arthritis
    Transkei, South Africa: 3-5 mg intake of boron: 3-4% with arthritis
    Carnarvon, West Australia: 6-10 mg intake of boron: 1% have arthritis
    Israel: 5-8 mg intake of boron: 1% have arthritis
    Ngawha, New Zealand: >10 mg intake of boron: none have arthritis

    Now before you start taking boron supplements, please look into drug interactions and side effects.

    What is the acai berry?

    The acai berry is an inch-long reddish, purple fruit. It comes from the acai palm tree (Euterpe oleracea), which is native to Central and South America.
    Research on the acai berry has focused on its possible antioxidant activity. Theoretically, that activity may help prevent diseases caused by oxidative stress such as heart disease and cancer.

    Is the acai berry healthy?

    Acai contains several substances called anthocyanins and flavonoids.
    The word anthocyanin comes from two Greek words meaning “plant” and “blue.” Anthocyanins are responsible for the red, purple, and blue hues in many fruits, vegetables, and flowers. Foods that are richest in anthocyanins -- such as blueberries, red grapes, red wine, and acai -- are very strongly colored, ranging from deep purple to black.
    Anthocyanins and flavonoids are powerful antioxidants that help defend the body against life's stressors. They also play a role in the body's cell protection system. Free radicals are harmful byproducts produced by the body. Eating a diet rich in antioxidants may interfere with aging and the disease process by neutralizing free radicals.
    By lessening the destructive power of free radicals, antioxidants may help reduce the risk of some diseases, such as heart disease and cancer.

    Are there known health benefits of acai berries?

    Some studies show that acai fruit pulp has a very high antioxidant capacity with even more antioxidant content than cranberry, raspberry, blackberry, strawberry, or blueberry. Studies are ongoing, though, and the jury is still out.
    People eat acai berries to address various health conditions. But so far, acai berries have no known health benefit that’s any different than that of other similar fruits.

    Can acai berries boost weight loss?

    Scientists are learning more about the functional power of superfoods, such as the acai berry. Although acai is touted in some weight loss products, few studies have tested the benefit of acai in promoting weight loss.
    For now, plenty of research supports eating a diet rich in antioxidants. There’s no doubt that berries and other fruits are a key part of any healthy diet promoting weight loss. The jury’s still out on whether there is something special about acai’s ability to shed excess pounds.

    Why are acai berries used in beauty products?

    Some cosmetics and beauty products contain acai oil in the ingredient list. That’s because acai oil is a powerhouse of antioxidants.
    Studies show that acai oil may be a safe alternative to other tropical oils used in beauty products such as facial and body creams, anti-aging skin therapies, shampoos and conditioners, and other products. When acai oil is processed and stored long-term, the antioxidant levels remain high.

    Do acai berries and acai juice have any side effects?

    If you have pollen allergies or have a known hypersensitivity to acai or similar berries, you may want to avoid this fruit. When eaten in moderate amounts, though, acai is likely safe.
