Here are 15 health benefits of avocados:

1.                  Maintain a healthy heart
Avocado contains vitamin B6 and folic acid, which help regulate homocysteine levels. High level of homocysteine is associated with an increased risk of heart disease. Besides that, avocado also contains vitamin E, Glutathione and monounsaturated fat which help in maintaining a healthy heart.
2.                  Lower cholesterol levels
Avocados are rich in a compound called beta-sitosterol which has been shown to be effective in lowering blood cholesterol levels. According to a study, patients with mild hypercholesterolemia who included avocados in their diet for 7 days had 17 percent decrease in total blood cholesterol levels, a 22 percent decrease in both LDL (bad cholesterol) and triglyceride levels, and a 11 percent increase in HDL (good cholesterol) levels.
3.                  Control blood pressure
Avocados are also a great source of potassium, which helps in controlling blood pressure levels.
4.                  Anti-Inflammatory properties
Phytonutrient compound found in avocados, such as polyphenols and flavonoids have been found to have anti-inflammatory properties, thereby reducing the risk of inflammatory and degenerative disorders.
5.                  Promote eye health
Avocado is an excellent source of carotenoid lutein, which known to help protect against age-related macular degeneration and cataracts.
6.                  Regulate the blood sugar levels
The monounsaturated (good) fats in avocados can reverse insulin resistance, which helping to regulate the blood sugar levels. Avocados also contain more soluble fiber, which keep a steady blood sugar levels.
7.                  Prevent birth defects
Avocados are rich in folate, a B vitamin commonly known as folic acid. One cup of avocado provides you about 23% of the Daily Value for folate. The high amount of folate in avocado is essential in the prevention of birth defects, such as neural tube defect and spina bifida.
8.                  Reduce strokes risk
The high levels of folate in avocados also protect against stroke. A study has shown individuals who ate a diet rich in folate had a lower risk of stroke than those who do not
9.                  Protect against cancer
Many studies have shown that avocado can inhibit the growth of prostate cancer. The oleic acid in avocado is also effective in preventing breast cancer.
10.              Fight free radicals
Avocados contain glutathione, a powerful antioxidants to helps fight free radicals in the body.
11.              Anti-aging properties
Being rich in antioxidants, avocado is beneficial in preventing aging symptoms. The glutathione in avocado may boosts immune systems, slows the aging process, and encourages a healthy nervous system.
12.              Cure bad breath
Avocados are one of the best natural mouth wash and bad breath remedies. It is cleanses intestine which is the real cause of coated tongue and this unpleasant condition.
13.              Increase nutrient absorption
Avocado intake is linked with increased nutrient absorption. A study suggests that, when participants ate salad included avocados, they absorbed five times the amount of carotenoids (a group of nutrients that includes beta carotene and lycopene) than those who do not include avocados.
14.              Skin Care
The avocado oil is added in many cosmetics because of its ability to nourish the skin and make your skin glow. It also aids in treating psoriasis, a skin disease that causes skin redness and irritation.
15.              Weight gain

Amazing Facts of Parsley


As we have mentioned before Parsley is a good remedy in kidney problems. Today another article about parsley will give us knowledge about parsley. I hope all of us enjoy reading.
Parsley is the most popular herb. Usually it is used as a garnish for some recipes because of its decorative appearance.
This highly nutritious plant can be found all year round in all local supermarkets. Parsley is very easy to grow, it can easily plant it in garden, in a container, or in hanging baskets.
Parsley is famous for having delicious vibrant taste, but also unknown to many, having contains good healing properties.

Parsley provides two unique health benefits its “essential oil” and “flavonoids”.
An organic compound called myristicinalso found in Parsley. Studies show that this compound can:
· myristicin inhibit tumor formation particularly in the lungs.
· myristicin help the molecule glutathione to fight against free radicals that would otherwise damage the body.
· myristicin neutralize carcinogens like benzopyrene, which is present in tobacco or cigarette smoke and charcoal grill smoke.
Another compound flavonoid  is also found in Parsley it is called luteolin. In various studies it shows that this compound can:
· luteolin function as an antioxidant, thereby eliminating free radicals from the body that can damage cells.
· luteolin  help increase antioxidant levels in the blood
· luteolin  help prevent several types of cancer such as breast cancer, colon cancer, lung cancer, ovarian cancer, pancreatic cancer, prostate cancer, and leukemia.

Parsley is a good source of vitamin C and vitamin A. Vitamin C is the body's primary water-soluble antioxidant, which can remove free radicals in all water-soluble areas of the body. Therefore, it can help prevent various diseases such as asthma, atherosclerosis, colon cancer, and diabetes.

As a matter of fact, people consuming foods with good amounts of vitamin C have a lower risk of acquiring these diseases.
Meanwhile, beta-Carotene (a precursor of vitamin A) is the body's primary fat-soluble antioxidant, which can get remove of free radicals in all fat-soluble areas of the body. Like vitamin C, it can also help lower the risk of atherosclerosis, colon cancer, and diabetes.
Studies show that people who consumed the lowest amounts of vitamin C-rich foods were at risk of developing arthritis by as much as three times more than those who consumed the highest amounts of vitamin C.
Vitamin C combined with beta-Carotene found in parsley can prove beneficial in inflammatory diseases like asthma, rheumatoid arthritis and osteoarthritis.
Since vitamin C is vital for strengthening the immune system, it can help prevent many common infections like colds and flu. Beta-Carotene is converted by the body to vitamin A. Vitamin A is an immune system regulator, which can make the white blood cells destroy bacteria and viruses.
One of the most essential B vitamins is “folic acid”, naturally produce by Parsley.
Studies show that folic acid can:
· folic acid keep the heart healthy and maintain its function.
· folic acid ower the risk of stroke and heart disease.
· folic acid remove homocysteine in the body.

Note: Homocysteine is an amino acid used by the body to manufacture proteins and in cellular metabolism. However, a high concentration of homocysteine in the blood can damage the lining of the blood vessels and enhance blood clotting, which can significantly increase the risk of stroke or heart attack.
Finally Parsley is rich in chlorophyll, which can act as a natural deodorizer. Eating parsley makes us sure that we will be able to maintain a fresh breath everyday.

Green Tea Helps Burn Fat Because It Is Rich In Catechin

Green Tea

Green tea helps burn fat because it is rich in catechin. By increasing the amount of energy that your body uses, Green tea helps promotes weight reduction, making it easier to use the excess body fat. These Catechins found in foods other than green tea do not seem to have this positive effect.

As we believe green tea isn't just a solution for weight reduction. Without wondering Green tea is also good in reducing both high cholesterol and high blood pressure. It also prevents premature aging and fight free radicals. Green Tea is natural remedy for constipation, too! It has really lots of advantages in our body.

Green Tea Leaves

When we look at people who are able to maintain their ideal weight, most of them are chewing their food properly. The problem with most people is that they chew their food too fast.

If we chew your food 30 to 50 times per mouthful, we should be able to consume less food and aid you in losing weight. Chewing slower also increases histamine in your brain, which will result to decreased food intake. Histamine works by suppressing your appetite! It will help satisfy your stomach with only small amount of food.

Some medical studies reveal that, catechin from green tea helps prevent or inhibit certain types of cancer. We must know that green tea drinkers usually live longer. As evidence, in some places that green teas are abundant people live as long as 100 years or more.

Great Sex Health Benefits

Great Sex Health Benefits

Researchers have shed light on the myriad health benefits that an individual can reap from great sex.

"Having sex regularly can do more than make you feel closer to your partner-it can actually make you physically healthier," ABC News quoted Dr. Hilda Hutcherson, a clinical professor of obstetrics and gynecology at Columbia University as saying.

Research from the University of the West of Scotland divulged that people who had intercourse at least once over two weeks were better able to manage stressful situations such as public speaking, said study author and psychology professor Stuart Brody, Ph.D.

That is because endorphins and oxytocin are released during sex, and these feel-good hormones trigger pleasure centres in the brain that create feelings of intimacy and relaxation and help stave off anxiety and depression, said WH advisor Laura Berman, Ph.D., an assistant clinical professor of ob-gyn and psychiatry at the Feinberg School of Medicine at Northwestern University and author of "It's Not Him, It's You!"

You don't have to climax to net the effects, but you'll get the biggest surge of soothing hormones if you have an orgasm. Just one more reason to shoot for a stellar finish!

Sex also ensures sounder sleep because the same endorphins that help you de-stress can also relax your mind and body, priming you for slumber, said Cindy M. Meston, Ph.D., director of the Sexual Psychophysiology Laboratory at the University of Texas at Austin. Additionally, during orgasm, the hormone prolactin is released.

"Prolactin levels are naturally higher when we sleep, which suggests a strong relationship between the two," she said.

However, extremely active sex can make you feel more energized than sleepy. Sex should never be a snooze, but if you want to use knocking boots as a sleep aid, skip the acrobatics and opt for a subdued session.
Sex can also help minimize pain. The surge of hormones released after an orgasm can help ease any annoying ache, whether it's a strained back or a head pounder, asserted Meston.

A study conducted at the Headache Clinic at Southern Illinois University revealed that half of female migraine sufferers reported relief after climaxing.

"The endorphins that are released during an orgasm closely resemble morphine, and they effectively relieve pain," said Meston.

Sex also results in fewer colds. People who have sex were found to have higher levels of an antibody called immunoglobulin A (IgA), according to researchers at Wilkes University in Pennsylvania. These antibodies help fight diseases and keep the body safe from colds and flu.

Amazing Health Benefits of Green Tea That Everyone Should Know

Green Tea Leaf

I found this very interesting health benefits of green tea that everybody should know.

Lowers your risk of cancer. Although the studies of how green tea affects cancerous cells are still in their infancy, there have been human trials which indicate that it does inhibit cells from developing cancer. EGCG in green tea regulates and inhibits cancer growth by killing cells that are growing inappropriately. In Japan, a study of 500 women with Stage I and Stage II breast cancer found that increasing their green tea consumption before and after surgery significantly lowered the risk of recurrence. Another analysis of 22 studies of the correlation between green tea and lung cancer concluded that by increasing your intake of green tea by two cups a day may reduce the risk of developing lung cancer by 18%.

Eases the pain of rheumatoid arthritis.
 Study results reported in the Proceedings of the National Academy of Sciences shows that polyphenol antioxidants in green tea benefits suffers of arthritis by reducing the incidence and severity of the disease. EGCG protects cartilage destruction and reduces joint swelling and pain. This leads many scientists and health professionals to recommend green tea as a legitimate remedy for treating arthritis.

Stabilizes your cholesterol levels. Researchers believe that green tea lowers your cholesterol levels by reducing its absorption in your digestive tract and increasing the rate of which it is excreted. However, your body does need cholesterol to build cell membranes, insulate nerve fibres and create hormones. For this, green tea benefits you by preventing the conversion of LDL cholesterol into it’s more dangerous, oxidized form. Oxidized LDL is one of the main factors in the development of atherosclerosis (the build of plaque that blocks your arteries as LDL gets sticky and clings to your artery walls) and increases your risk of heart attack or stroke. The amazing antioxidant effects of green tea protect this, helping to keep your arteries clean.

Prevents cardiovascular disease. A Japanese study published in the Journal of the American Medical Association showed significant reductions in deaths from cardiovascular disease among green tea drinkers. The study found that over an 11 year test period, individuals who drank more than 5 cups per day had a 16% less chance of mortality and mortality related to cardiovascular disease when compared to individuals who drank less than one cup per day. They also found that green tea was especially beneficially in preventing strokes, due in large part to the antioxidants and how they prevent clogged arteries.

Boosts your immune system. Catechins, the antioxidant polyphenol compounds, have been shown to have a major impact in your immune system. Research conducted by the Brigham and Women’s Hospital in 2003 revealed that theanine, found in green tea, boosted the activity of the gamma delta T cells that form part of our adaptive and innate immunity. The study followed a group of coffee drinkers and a group of tea drinkers who each drank 600ml of their drink daily. Blood samples taken four weeks later quite clearly showed that production of these anti-bacterial proteins were five times higher in those drinking tea.

Promotes weight loss. Both green tea and green tea extract have been shown to fight obesity and lower LDL cholesterol – both of which ultimately lead to a reduced risk of heart disease and diabetes. The polyphenols in green tea are extremely useful for dissolving triglycerides, a substance in the liver and small intestine made up of mostly sugar and fat, and this is thought to be the reasongreen tea benefits fat loss. EGCG is also known to stimulate your metabolism and accelerate weight loss. When combined with the caffeine in green tea, this causes your central nervous system to release fat into the bloodstream to be used as fuel which burns your body fat off.

Reduces tooth decay. Antibacterial properties found in green tea are also used by your body to kill the bacteria that causes plaque on your teeth. Research by the Journal of Periodontology has also shown that for every cup of green tea you drink, there is a decrease in indicators for gum disease. Fluoride is also found ingreen tea which helps to protect against cavities.

Effective in the treatment of multiple sclerosis. In 2007, Dr. Orhan Aktas from the Institute of Neuroimmunology conducted a study of how green tea benefits sufferers of multiple sclerosis. While current patients do not have many options to prevent tissue damage and disability, he found that the flavonoid EGCG found ingreen tea could have a huge impact on multiple sclerosis. He concluded that EGCG is capable of directly protecting against neuronal injury in living brain tissue and that EGCG constituents may open up a new therapeutic avenue for treating MS by combining anti-inflammatory and neuroprotective capacities.

Slows the onset of Alzheimer’s and Parkinson’s disease. A recent report published in the journal Phytomedicine has found substantial evidence that the enzymes found in green tea protect your brain cells from damage. Another study conducted by the University of South Florida looked at the effects of antioxidant EGCG. It was shown to be a protein blocker which prevented the chemical reactions that can lead to nerve damage that can lead to Alzheimer’s and Parkinson’s.

Fights the cause of allergies in your body. Methylated epigallocatechin gallate (EGCG) has been shown to block a cells receptor involved in producing an allergic response. By blocking the production of histamine and immunoglobulin E (IgE), two compounds in the body that are chiefly involved in triggering and sustaining allergic reactions, EGCG could very well be the compound which prevents you from having watery eyes, sneezing and coughing.

Helps to fend off infections. Again, as one of the main benefits of green tea, EGCG has been highlighted by a study published in the Journal of Allergy andClinical Immunology as being able to prevent infections, including the HIV virus. EGCG binds with CD4 immune system T-cell receptors and stops HIV from doing the same to reduce the risk of infection. While it is still way too early to peggreen tea as a cure for HIV, an Egyptian study has shown that combining antibiotics with green tea significantly boosts the effectiveness of the antibiotic. In fact, when tested against 28 disease-causing microorganisms, green tea enhanced the bacteria killing power in every single case.

Reduces and prevents acne. Green tea benefits acne in a number of different ways. It’s antibacterial properties attack and kill the acne bacteria while the anti-inflammatory benefits of green tea reduce the swelling and redness. Antioxidants fight against free radicals which damage the skin and make it more susceptible to acne also help to balance hormone levels to help prevent future breakouts from happening.

Slows the aging process to prevent wrinkles. One of the latest benefits ofgreen tea is the effect it has on your skin and the aging process. It is again down to the antioxidants that prevent cell oxidation and damage that can make you look older than you really are. Studies are mixed on this particular green tea benefit as new research has come to light which suggests the full benefits can only be had by applying green tea topically to your skin. However, many people have found that potent green tea extracts do have a positive effect on their skin, leaving it softer, more supply and younger looking.

 Enjoy your green Tea and be healthy always!

A banana a day keeps the doctor away!

Sweet Banana

For many illness banana is a natural remedy after eating breakfast lunch or dinner I always eat banana. If we compare banana to an apple, banana has four times the protein, twice the carbohydrates, three times the phosphorus, five times the vitamin A and iron, and twice the other vitamins and minerals. Banana also is rich in potassium and is one of the best value foods we have.

Bananas contain three natural sugars - sucrose, fructose and glucose combined with fiber, a banana gives an instant, sustained and substantial boost of energy. Research has proven that just two bananas provide enough energy for a strenuous 90-minute workout. No wonder the banana is the number one fruit with the world's leading athletes. But energy isn't the only way a banana can help us keep fit. It can also help overcome or prevent a substantial number of illnesses and conditions, making it a must to add to our daily diet.

Sweet Banana


According to a recent survey undertaken by MIND amongst people suffering from depression, many felt much better after eating a banana. This is because bananas contain tryptophan, a type of protein that the body converts into serotonin, known to make you relax, improve your mood and generally make you feel happier.


Forget the pills -- eat a banana. The vitamin B6 it contains regulates blood glucose levels, which can affect your mood.


High in iron, bananas can stimulate the production of hemoglobin in the blood and so helps in cases of anemia.

Blood Pressure:

This unique tropical fruit is extremely high in potassium yet low in salt, making it the perfect way to beat blood pressure. So much so, the US Food and Drug Administration has just allowed the banana industry to make official claims for the fruit's ability to reduce the risk of blood pressure and stroke.

Brain Power:

200 students at a Twickenham school were helped through their exams this year by eating bananas at breakfast, break, and lunch in a bid to boost their brain power. Research has shown that the potassium-packed fruit can assist learning by making pupils more alert.


High in fiber, including bananas in the diet can help restore normal bowel action, helping to overcome the problem without resorting to laxatives.


One of the quickest ways of curing a hangover is to make a banana milkshake, sweetened with honey. The banana calms the stomach and, with the help of the honey, builds up depleted blood sugar levels, while the milk soothes and re-hydrates your system.


Bananas have a natural antacid effect in the body, so if you suffer from heartburn, try eating a banana for soothing relief.

Morning Sickness:

Snacking on bananas between meals helps to keep blood sugar levels up and avoid morning sickness.

Mosquito bites:

Before reaching for the insect bite cream, try rubbing the affected area with the inside of a banana skin. Many people find it amazingly successful at reducing swelling and irritation.


Bananas are high in B vitamins that help calm the nervous system.

Overweight and at work?

Studies at the Institute of Psychology in Austria found pressure at work leads to gorging on comfort food like chocolate and chips. Looking at 5,000 hospital patients, researchers found the most obese were more likely to be in high-pressure jobs. The report concluded that, to avoid panic-induced food cravings, we need to control our blood sugar levels by snacking on high carbohydrate foods every two hours to keep levels steady.

The banana is used as the dietary food against intestinal disorders because of its soft texture and smoothness. It is the only raw fruit that can be eaten without distress in over-chronicler cases. It also neutralizes over-acidity and reduces irritation by coating the lining of the stomach.

Temperature control:

Many other cultures see bananas as a "cooling" fruit that can lower both the physical and emotional temperature of expectant mothers. In Thailand, for example, pregnant women eat bananas to ensure their baby is born with a cool temperature.

Seasonal Affective Disorder (SAD):

Bananas can help SAD sufferers because they contain the natural mood enhancer tryptophan.


Bananas can also help people trying to give up smoking. The B6, B12 they contain, as well as the potassium and magnesium found in them, help the body recover from the effects of nicotine withdrawal.


Potassium is a vital mineral, which helps normalize the heartbeat, sends oxygen to the brain and regulates your body's water balance. When we are stressed, our metabolic rate rises, thereby reducing our potassium levels. These can be rebalanced with the help of a high-potassium banana snack.


According to research in "The New England Journal of Medicine," eating bananas as part of a regular diet can cut the risk of death by strokes by as much as 40%!

Onions and Mayonnaise

Red Onion

I receive an email which is very useful and interesting I want 
this to all of you here we go...

In 1919 when the flu killed 40 million people there was this Doctor that visited the many farmers to see if he could help them combat the flu.

Many of the farmers and their family had contracted it and many died.

The doctor came upon this one farmer and to his surprise,  everyone in his family was very healthy. When the doctor asked what the farmer was doing that was different the wife replied that she had placed an unpeeled onion in a dish in the rooms of the home (probably only two rooms back then). The doctor couldn't believe it and asked if he could have one of the onions and placed it under the microscope. She gave him one and when he did this, he did find the flu virus in the onion. It obviously absorbed the bacteria or viruses, therefore,  keeping the family very healthy.

Now, I  heard this story from my hairdresser in Arizona (AZ). She said that several years ago many of her employees were coming down with the flu and so were many of her customers. The next year she placed several bowls with onions around in her  shop. To her surprise, none of her staff got sick. It must work. Try it and see what  happens. We did it last year and we never got the flu.

Now there is a P.S. to this for I sent this to a friend in Oregon who regularly contributes material to me on health  issues. She replied with this most interesting  experience about onions:

"Thanks for the  reminder. I don't know about the farmer's story..  But, I do know that I contacted pneumonia and  needless to say I was very ill.. I came across an article that said to cut both ends off an onion put it into an empty jar...placing the jar next to the sick patient at night. It said the onion would be black in the morning from the  germs.. Sure enough it happened just like that...The onion was a mess and I began to feel better. 

"Another thing I read in the article was that onions and garlic placed around the room  saved many from the black plague years ago. They  have powerful antibacterial, antiseptic properties."

This is the other note:

"Lots of times when we have stomach  problems we don't know what to blame. It's probably the onions that are to blame. Onions absorb bacteria and the very reason they are so good at  preventing us from getting colds and flu---and therefore also the very reason we shouldn't eat an onion  that has been sitting for a time after it has  been cut open.


"I had the wonderful privilege of touring Mullins Food Products, Makers of Mayonnaise. Questions about food poisoning came up, and I wanted to share what I learned from a chemist.

"The guy who gave us our tour is named Ed. Ed is a chemistry expert and is involved in developing most of the sauce formula. He's even developed sauce formula for McDonald's.

"Keep in mind that Ed is a food chemistry whiz. During the tour, someone asked if we really needed to worry about  mayonnaise. People are always worried that  mayonnaise will spoil. Ed's answer will surprise  you. Ed said that all commercially- made  Mayo is completely safe.

"It  doesn't even have to be refrigerated. No harm in  refrigerating it, but it's not really  necessary. He explained that the pH in  mayonnaise is set at a point that bacteria could not survive in that environment. He then talked about the quint-essential picnic, with the bowl of potato salad sitting on the table and how everyone blames the mayonnaise when someone gets sick.

"Ed says when food poisoning is reported, the first thing the officials look for is when the 'victim' last ate ONIONS and where those onions came from (in the potato  salad?). 

"Ed says it's not the mayonnaise (as  long as it's not homemade Mayo) that spoils in the outdoors. It's probably the onions, and if not the onions, it's the POTATOES.

"He explained, onions are a huge magnet for bacteria, especially uncooked onions. You should never plan to keep a portion of a sliced onion...He says it's not even safe if you put it in a zip-lock bag and put it in your refrigerator.

"It's already contaminated enough just by being cut open and out for a bit, that it can be a danger to you (and doubly watch out for those onions you put in your hotdogs at the baseball park)!

"Ed says if  you take the leftover onion and cook it like crazy you'll probably be okay, but if you slice that leftover onion and put it on your sandwich, you're asking for trouble. Both the onions and the moist potato in a potato salad will attract and grow bacteria faster than any commercial  mayonnaise will even begin to break down.

"Also, dogs should never eat onions. Their stomachs cannot  metabolize onions.

"Please remember it is dangerous to cut an onion and try  to use it to cook the next day, it becomes highly poisonous for even a single night and creates toxic bacteria which may cause adverse stomach infections because of excess bile secretions and even food  poisoning."

Please share this on to all you love and care.
