Studies regarding probiotics has revealed its significant potential in reducing the risk of acquiring common cold especially during the cold months of winter.

There are over 500 million cases of the common cold in the United States each year. Rhinoviruses are identified as the culprit causing this viral infection. For the common cold alone, the cost amounts to a whopping $40 billion each year. This is according to a study on common cold published in the Archives of Internal Medicine.

A group of researchers,led by Anna Berggren of Sweden, conducted a study regarding the undiscovered health benefits of probiotics. Probiotics are live microorganisms that positively influence the health of its host. Bifidobacteria and lactic acid bacteria are the two most common microbes used as probiotics, and there are several strains of probiotics depending on the process by which it is cultured. Lactobacillus plantarum and lactobacillus paracasei were shown to have positive influence against common colds.

The results of the study revealed that individuals who were taking the strains of probiotics had a 55 percent reduction in incidents of catching the common cold. The researchers added that the duration of the symptoms was also reduced by probiotics and concluded that it is effective in reducing the risk of acquiring common cold. This study was published in the European Journal of Nutrition. It consisted of 272 healthy participants taking probiotic supplement for 12 weeks.

The consumption of probiotics alongside other effective immune boosters can reduce the risk of an upper respiratory tract infection like otitis, sinusitis, pharyngitis, and rhinitis. It has also been observed to have preventive benefits against cold to children in day care centers. This additional study on the health benefits of probiotics against common cold in Croatians was published in Clinical Nutrition on June of 2010.

Understanding Probiotics

Probiotics have been proven by medical studies to have numerous health benefits to the body when taken in adequate amount. They can come in the form of bifidobacteria, lactic acid bacteria, bacilli and even in yeast form. Probiotics are usually found in fermented foods such as yogurts and dietary supplements. Japan is one of the leaders in culturing probiotics and it is one of the countries with the most products containing probiotics in the market.

Unlike other bacteria that are known to have harmful effects to the body, probiotics help the body fight bad bacteria while providing support to the immune system at the same time.  This support readies the body from future attacks. Studies on the benefits of probiotics even suggest that it is not only beneficial in preventing some types of diseases but it may also have curative properties. Clinical studies since the middle of the 1990s have established significant evidence that probiotics can help in overcoming several gastrointestinal diseases. These bacteria settle in the gut and keep pathogens and other harmful microorganisms from harming the body and helps in the proper function of the immune system.

Health Benefits of Probiotics

Probiotics are being continuously subjected to experiments and scientific studies to discover and obtain proof of its medicinal uses and health benefits. However, there are only preliminary results available and most of the potential benefits of probiotics need further research. Despite that, probiotics have been proven to be safe for human consumption and scientists are spending time and effort in obtaining proof of its value in influencing the immune system, in fighting cancer, and as a bio-therapeutic agent for severe diarrhea and irritable bowel movement.

The health benefits of probiotics are as follows;

Lactose Intolerance

Probiotics may help lactose-intolerant individuals adapt to more lactose. Therefore, the person can drink milk since probiotics helps the body convert lactose into lactic acid more easily and at a faster rate.

Lowering Cholesterol Levels

A popular strain of probiotics, lactobacillus bulgaricus (LAB), had demonstrated significance by helping break down bile produced by the gut. This helps break down cholesterol and has the resultant effect of lowering cholesterol levels. For human subjects who were fed with LAB, some showed reduced levels of cholesterol in their body.

Colon Cancer Prevention

In clinical investigations, Lactobacillus bulgaricus has demonstrated to have significant influence over the mutation of colon cancer cells. LAB has the ability to bind with carcinogenic substances called heterocyclic amines, which are found in cooked meat. This is one of the compounds thought to cause colon cancer. Laboratory experiments made on rodents with regards to the effects of LAB on colon cancer have shown promising results. However, the results in human trials are insufficient and conflicting. Although it has been recorded by a population study that people with high fermented dairy consumption has lower risk of developing colon cancer.

Immune System

Probiotics can protect the body against diseases by competing with pathogens in terms of growth and thus helping improve the immune function. Clinical studies have proven that probiotics help prevent and decrease the severity of respiratory tract infections, diarrhea, and rotavirus infection in children. Probiotics is also beneficial in counteracting the side effects of antibiotics by keeping the immune system alert and ready to take over once the body stops taking antibiotics.

Reduction of Inflammation

Clinical studies have revealed that probiotics can regulate the cytokine function of the body. In effect, it regulates the body’s hypersensitivity and inflammatory responses.

Other Health Benefits of Probiotics

Probiotics have also been observed to improve the bioavailability of nutrients such as calcium, iron, copper, zinc, phosphorus, magnesium and B vitamins. It is also being studied to have beneficial effects in maintaining the acidity of the female genital environment thereby preventing the onset of bacterial vaginosis, urinary tract infection and yeast infection.

Healthy Tips to Prevent the Common Cold

The common cold can be prevented by taking sufficient dosage of probiotics and immune boosting foods and adequate exercise. There are over 200 different viruses that cause the common cold.  Remember that cold symptoms vary when it comes to its levels of severity.

Aside from maintaining a healthy lifestyle, it also important to be watchful of where you put your hands. Cold-causing viruses can spread through droplets and can live outside the body for an extended period of time. Touching surfaces may transmit the virus. So here are a few tips to live by:

• Avoid touching your face. You can also use a hand sanitizer or any form of disinfectant to keep your hands clean while you are on the go.
• Always keep it a habit to wash your hands frequently
• If you have colds, be proactive when it comes to keeping the infection from spreading by throwing your used tissues properly, covering your mouth when you sneeze and by staying at home to avoid contact with other people as much as possible.

Kiwifruit, a world favorite, is now being seen as one of the leading “super foods” around because of myriad of health benefits, including its prebiotic potential and anti-cancer potential.

In a recently published Journal of Functional Foods, researchers from the NZ Institute of Plant and Food Research claim that pectin that has been derived from kiwifruit may help improve the levels of good bacteria in the digestive tract.

The humble pectin… was actually a health superstar!

The same pectins (the researchers found a total of six varieties of pectin in the species Actinidia deliciosa) the study says, may also help protect the good bacteria as they flourish in the digestive tract.  A growing body of studies suggest that the once humble pectin (usually used as a gelling agent for fruit jams and as material for encapsulating supplements and drugs) can provide the following benefits:

• Better digestion with pectin’s natural fiber content
• Prebiotics
• Increased heart health with its capacity to lower LDL (low density lipoproteins) or “bad cholesterol”

Compared to inulin fiber, the pectins from kiwifruit showed an enhanced effect on the good bacterias Lactobacillus rhamnosus and Bifidobacterium bifidum. The pectins also helped the body fend off bacterial invasions by lessening the adhesion of bad bacteria like Salmonella typhimurium.

Prebiotics?

The majority of health-inclined individuals around the world know of prebiotics. But how about prebiotics? What do they do?

Probiotics are compounds that encourage the growth and flourishing of good bacteria or essential bacteria in the digestive tract.  They directly contribute to the growth of the organisms in the intestinal flora.

Prebiotics on the other hand, protect the bacterial growth in the intestinal flora.  Since prebiotics are non-digestible substances they can also help carry away waste from the intestines.  Prebiotics are also important because they prolong the life of good bacteria and  they also keep the bacteria healthy.

Other benefits of prebiotics include:

1. May help ease the symptoms of diarrhea caused by taking antibiotics
2. Also helps people suffering from traveler’s diarrhea.
3. Helps reduce the pain and inflammation associated with gastroenteritis.
4. Helps normalize and regulate bowel function.
5. May help improve colitis
6. Can help reduce the incidence of irritable bowel problems.
7. Helps the body absorb calcium
8. Can help strengthen the immune system

Natural sources of prebiotics include:

• Whole grain products
• Leguminous foods
• Onions
• Fresh honey
• Fresh and cooked greens
• Garlic
• Yogurt, milk and other dairy products
• Different types of berries
• Bananas
• Apple cider vinegar (raw, not cooked)
• Jerusalem artichokes
• Other grains (gluten-free)

Amazing benefits of kiwifruit

Does kiwifruit offer other benefits other than prebiotics? Yes! Here are some of the main benefits of getting your healthy dose of kiwifruit everyday:

1. Kiwifruit is rich in vitamins and minerals, including ascorbic acid (vitamin C – one kiwifruit has more vitamin C than a regular orange), beta carotene and potassium. Potassium is brain food that increases one’s alertness and also improves one’s memory.

2. According to research performed in Italy, kiwifruit can also help improve the health of the respiratory tract. Seven portions of the fruit every week can yield respiratory benefits (respondents, children aged six to seven, showed less wheezing and shortness of breath compared to other respondents who received little or no kiwifruit throughout the testing period)

3. Kiwifruit  can also help ward off the effects of age-related macular degeneration.

4. Kiwifruit is a potent source of natural antioxidants, which can help reduce the incidence of certain types of cancer, heart disease and can also improve one’s vision.

5. Kiwifruit is a natural source of soluble fiber, which improves the digestive function and also helps transport human waste more efficiently.

6. Kiwifruit may be helpful in reducing harmful mutations or changes to one’s DNA. This is important in keeping your DNA pristine for the next generation (your children, who will be receiving your DNA – and all that comes with it, including risks to certain types of diseases, etc.)

7. Kiwifruit, because of its high soluble fiber content, can help individuals with insulin-dependent diabetes (or type-2 diabetes) and people with high cholesterol. Natural fiber has been known to control blood glucose levels and bad cholesterol levels.

8. Also due to its high fiber content, kiwifruit may also help prevent deadly colon cancer.

9. Kiwifruit is a natural source of the nutrient inositol. Recent studies show that inositol is very beneficial as a supportive treatment for depression.

10. It contains the compound arginine, which is capable of dilating or opening up constricted blood vessels.  As such, it is not only good for people with hypertension but is also very beneficial for males suffering from impotence or erectile dysfunction. Arginine has been long used for the treatment of impotence in males.

11. In China, a study made use of kiwifruit to see whether Chinese athletes can last longer during the rigorous physical exertion during training.  With the addition of five percent carbohydrates to kiwi juice, the athletes were able to last longer – their blood glucose levels remained stable after taking the kiwi juice.

12. Amazingly, this small fruit also has a high percentage of the natural brain chemical serotonin. This compound has a relaxing effect when utilized by the body.

Kiwifruit is a type of fruit that provides the best ratio of calories to fiber & essential nutrients.

Beta-glucan sourced from the barley plant and barley-based products can help improve the digestive tracts of people over 50 because of its probiotic potential.

Beta-glucan is a fibrous compound that naturally occurs in the cell walls of food such as the fiber of the barley plant and edible yeast.

Beta-glucan is also present in food mushrooms, such as the maitake mushroom.  Since it is nearly everywhere, eating food that has lots of beta-glucan may improve digestion, new study says.  Better digestion results from its seemingly probiotic effect, which is more noticeable in individuals fifty years old and above.

The study was published this year in Food Research International and is led by Adamantini Kyriacou, a researcher from the Harokopio University, which is based in Athens, Greece.

There should be no confusion with the term “probiotic”. According to Gibson et.al. in a related study on the human digestive process, probiotics is defined as non-digestible materials that have a positive or beneficial effect on the metabolism of the whole digestive tract.

Beta-glucan from oats & barley

The most widespread form of beta-glucan is found in oats. For many years now, this type of beta-glucan has already been associated with lower bad cholesterol (low-density lipoproteins) and has been tagged as a potential preventive for coronary heart disease.

The US Food and Drug Administration has already declared the link between specific oat products and better heart health.  More than a decade ago, the FDA established that a person only needs 3 grams of the compound to help lower cholesterol.

The Greek study endeavored to find out if beta-glucan derived from the barley plant produced the same positive effects.  The randomized study that involved more than fifty individuals (between the age of thirty-nine and seventy-two) showed that the positive probiotic effect was more apparent in the individuals over the age of fifty.

Some positive effects were also seen in younger respondents, but their response to the beta-glucan was not as statistically significant as the response of the fifty-plus year old respondents.

Other benefits of beta-glucan

Beta-glucan has also other established health benefits:

1. It binds to low-density lipoproteins (“bad cholesterol”) and removes them from the body, effectively reducing the cholesterol level in the body.
2. Beta-glucan has also been used to support the medical treatment of diabetes and obesity.  It may have some positive effects on weight loss efforts because it reduces cholesterol and improves heart health.
3. Beta-glucan can also be used as an immunostimulant.
4. For cancer patients, the addition of beta-glucan may help improve the digestive process and strengthen the immune system.
5. Beta-glucan is also capable of reducing the blood sugar level of diabetics.
