10 Symptoms of Thyroid Problems.

The thyroid gland is one of the body’s most important components. The thyroid regulates hormone balance and contributes to weight, mood, and mental stability—and that barely scratches the surface. Because of the thyroid’s influence on so many of the body’s important, and even “secondary” functions, an unhealthy thyroid can have far-reaching, unexpected, and odd effects that manifest into symptoms that many doctors fail to identify as thyroid-related. In fact, of the 12% of Americans that will develop thyroid disease, 60% will never know they have it. That’s a problem. Awareness is key, so to help, here are ten, easy-to-miss symptoms of thyroid problems.

1. Cholesterol That’s Too High or Too Low

Too much fat in your diet causes high cholesterol, right? Wrong. High cholesterol can have a number of originating factors, and diet is a small contributor compared to others. And, in some cases, low cholesterol may be a problem. If your cholesterol is off and diet and exercise don’t help, it may be time to consider the possibility of an underlying problem. If you take medication for cholesterol and it’s not working, it’s time to have your thyroid checked. You may have hypothyroidism, or low thyroid hormone levels. It’s always a good idea to get tested for hyperthyroidism, a condition caused by an overabundance of circulating thyroid hormone.

2. Sore Joints and Nerve Pain

Research has found that thyroid diseases, both hypo- and hyperthyroidism, can cause nerve pain. Getting thyroid health in check has produced improvements in wrist pain and tingling sensations in some people. In one case, a 60-year-old Italian woman suffering from a burning sensation in her feet displayed symptoms of hypothyroidism. As she progressed with her thyroid treatment, the pain went away.

3. Heart Disease

Thyroid hormones play a direct role in heart health, so if you have heart disease, you need to be aware of your thyroid status. A 2014 study out of John Hopkins University reported low thyroid hormone levels were common in young and middle-aged adults with early-stage coronary artery disease and blood vessel calcification. A Polish study similarly compared 25 patients with low levels of thyroid stimulating hormone to 25 patients with normal levels and found that those with lower levels had more cardiac events.

4. Weak, Fragile Fingernails

Fingernails that crack or flake may reflect thyroid problems, as those with hypothyroidism often have soft, fragile nails. Additionally, persons with hyperthyroidism often experience a nail that comes off the bed of the fingertip. In both cases, dry skin and brittle hair often accompany these symptoms.

5. Anxiety and Mood Imbalances

Your hormones play a huge role in affecting how you feel. Low hormone levels, such as in the case of hypothyroidism, can leave you feeling down in the dumps. Conversely, an excess of hormones can lead to anxiety or panic attacks. If you have feelings like this, it might be a good idea to get your thyroid tested before considering psychiatric drugs that could make your problems worse.

6. Inexplicable Weight Gain or Loss

If you’ve lost or gained weight and can’t explain why it could be your thyroid. Metabolism depends directly on hormone activity. A sudden change in weight, up or down, can be an indication of a thyroid imbalance.

7. Constant Fatigue

Constant fatigue is a common problem that often gets ignored. Many young adults write off fatigue and low energy as a sign of their lifestyle; but if you have an established routine and get regular sleep, you shouldn’t ignore chronic fatigue. If you get 7-8 hours of sleep and it’s not enough, it could be an early symptom of a thyroid issue. Those suffering from hyperthyroidism may find it hard to fall asleep, which can leave you dragging during waking hours.

8. Low Libido

Since the thyroid is all about hormones, it comes as no surprise men and women experience problems with their reproductive organs. Women can have a more frequent, longer menstruation with low hormones and shorter, light menstruation—or have a cycle stop altogether—with too many circulating hormones. Fertility may also be a problem. Men experience infertility, low libido, and may even develop enlarged breasts when sex hormones and the thyroid become imbalanced.

9. Gut Problems

IBS isn’t always caused by diet. In fact, metabolic imbalances may be to blame. This prevents necessary enzymes from getting to the gut to help with digestion. If constipation, diarrhea, or IBS are ongoing problems and therapies aren’t helping, it may be time to consider checking your thyroid.

10. Weakness

Hormone imbalances don’t exist in a vacuum, they often lead to other imbalances throughout the body, and an extreme dip in energy levels is one that’s standard. Your thyroid, metabolism, and energy levels are all connected. If you get enough sleep and follow a balanced diet and routinely provide your body with the complete nutrition it needs to perform its functions, and you still feel weak, it’s time to consider underlying possibilities, and your thyroid is one.

Promoting Thyroid Balance

Many factors influence thyroid health, and there are a few things you can do to encourage optimal thyroid function.

  1. Make sure you get enough iodine. It’s not a cure or treatment; it’s simply the exact nutrition your thyroid needs to function normally. Iodine-rich foods are one way to get your iodine requirements; an iodine supplement is another.
  2. Exercise regularly. The goal isn’t to become a bodybuilder; it’s to use and work your muscles—all of them. Get up and move around.
  3. Eat a balanced diet that meets all your nutritional requirements. Your body is like a Swiss watch; all its parts need to be precisely aligned for it to function properly as a whole. If you have nutritional deficiencies, of any kind, you’re not going to feel balance.

Selenium: The Missing Link?

Have you experienced thyroid problems that prove difficult to pinpoint? The culprit could be selenium deficiency. Selenium is an essential mineral that helps protect the thyroid and support normal thyroid function. As with iodine, you can get all the benefits of this mineral by consuming selenium-rich foods or by taking a high-quality selenium supplement.

Eight Potential Health Benefits of Kombucha

Kombucha is a sweet, fizzy drink made of yeast, sugar, and fermented tea. It has a number of potential health benefits, including gut health and liver function.

This article explores eight potential health benefits of kombucha and looks at the research that supports them.

What is kombucha?

A jar of raw kombucha fermented drink, on a wooden table with chopped up lemon and a stem of ginger.
Kombucha is a fermented drink that is popular for its purported health benefits.

To make kombucha, sweetened green or black tea is fermented with a symbiotic colony of bacteria and yeast, otherwise known as a SCOBY.

During the fermentation process, the yeast in the SCOBY breaks down the sugar in the tea and releases probiotic bacteria.

Kombucha becomes carbonated after fermentation, which is why the drink is fizzy.

Potential health benefits

There is a range of potential health benefits of kombucha, including:

1. Gut health

As this 2014 study confirms, the fermentation process of kombucha means that the drink is rich in probiotics. Probiotic bacteria are similar to healthful bacteria that are found in the gut.

Consuming probiotics may improve overall gut health. Probiotic bacteria have been found to help treat diarrhea, and some research suggests they may help ease irritable bowel syndrome(IBS).

More research is needed into how kombucha improves gut health, but the link between probiotics and gut health suggests it may support the digestive system.

The link between healthy bacteria in the digestive system and immune function is becoming clearer as more studies focus on gut health. If the probiotics in kombucha improve gut health, they may also strengthen the immune system.

2. Cancer risk

There is growing evidence to suggest drinking kombucha could help reduce the risk of cancer.

2008 study found that kombucha helped prevent the growth of cancer cells. Further research in 2013 found that kombucha decreased the survival of cancer cells. Both studies suggest kombucha could play a role in treating or preventing cancer.

It is important to note that these studies looked at the effects of kombucha on cancer cells in a test tube. More research is needed to see if people who drink kombucha have a reduced risk of developing cancer.

3. Infection risk

A type of acid called acetic acid, also found in vinegar, is produced when kombucha is fermented.

study carried out in 2000 found that kombucha was able to kill microbes and help fight a range of bacteria. This suggests that it may help prevent infections by killing the bacteria that cause them before they are absorbed by the body.

4. Mental health

The probiotics in kombucha are thought to have the ability to treat depression.

There may be a link between probiotics and depression, suggesting that drinking probiotic-rich kombucha could help promote positive mental health.

There are strong links between depression and inflammation so the anti-inflammatory effect of kombucha may help alleviate some of the symptoms of depression.

2017 review looked at a number of existing studies and concluded that there is strong evidence that probiotics may help treat depression. However, further research is needed to prove how effective they are.

5. Heart disease

Levels of certain types of cholesterol increase the risk of heart disease. Studies in 2012 and 2015 found that kombucha helps to reduce levels of the cholesterol linked to heart disease. Cholesterol levels and heart disease are also influenced by diet, exercise, weight, lifestyle habits, and inflammation. However, the research cited here suggests drinking kombucha may help reduce the risk of heart disease.

At the same time, it is important to note that these studies were in rats. More research is needed to prove that kombucha reduces the risk of heart disease in humans.

6. Weight loss

When kombucha is made with green tea, it may aid weight loss. A 2008 study found that obese people who took green tea extract burned more calories and lost more weight than those who did not.

If kombucha is made with green tea, it follows that it could have a similarly positive effect on weight loss.

Again, researchers need to look at kombucha and weight loss specifically before this is certain.

7. Liver health

Kombucha contains antioxidants that help fight molecules in the body that can damage cells.

Some studies, the most recent being in 2011, have found that the antioxidant-rich kombucha reduces toxins in the liver. This suggests that kombucha may play an important role in promoting liver health and reducing liver inflammation.

However, studies to date have looked at rats and more research is needed to say with certainty how kombucha can support liver health in humans.

8. Type 2 diabetes management

Kombucha may help to stabilize blood sugar levels and aid in the management of diabetes.

Kombucha may also be helpful in managing type 2 diabetes.

2012 study found that kombucha helped to manage blood sugar levels in rats with diabetes. This finding suggests it may be helpful in type 2 diabetes management.

Again, more research is needed to say with certainty whether kombucha can have the same benefits in type 2 diabetes management for humans.

Are there any risks?

It is important to be careful when making kombucha at home, as it can ferment for too long. It is also possible for kombucha to become contaminated when not made in a sterile environment.

Over-fermentation or contamination may cause health problems so it may be safer to buy kombucha in a store than to make it at home.

Store-bought kombucha normally has a lower alcohol content than homemade versions, but it is important to check the sugar content.

There are many potential health benefits of kombucha. However, it is important to remember that research is ongoing and not all benefits have been proven in studies with human participants.

If made properly or bought in-store, kombucha is a probiotic-rich drink that is safe to enjoy as part of a healthful diet.

Health Benefits of Oolong Tea

There is a record of tea being used as a beverage in China since 2,000 B.C.E. Besides water, it is consumed more than any other drink around the world. The four main types of tea are black, green, white, and oolong.

All four varieties come from the Camellia sinensis plant. Herbal teas are not considered true tea because they do not come from the Camellia sinensis plant.

Oolong tea accounts for only 2 percent of tea consumption around the world. Although less popular, oolong tea still has a variety of benefits. Read on to find out more information about oolong tea and its associated health benefits.

What is oolong tea?

Oolong tea is commonly consumed in China and Taiwan. In Asian countries, drinking tea is a large part of the culture and social gatherings. Friends and business associates often meet over tea.

Oolong
Oolong tea has a range of health benefits.

Although all true tea comes from the same plant, the differences occur in the harvesting and processing. Oolong tea is partially fermented, while black tea is fully fermented.

Tea can also differ in amounts and types of antioxidants. Green tea is high in a class of antioxidants known as catechins. Antioxidants in black tea are theaflavins and thearubigins. Oolong tea falls in the middle, regarding the antioxidant amounts.

Oolong tea and green tea contain similar amounts of caffeine, approximately 10 to 60 milligrams (mg) per 8-ounce cup. For comparison, coffee contains approximately 70 to 130 mg of caffeine per 8-ounce cup.

Unsweetened brewed tea is considered a zero-calorie beverage. It contains no fat, carbohydrates, or protein.

Potential health benefits of oolong tea

There are a number of health benefits that are thought to derive from drinking oolong tea, as with other types of tea.

Heart disease

Researchers in China studied the relationship between drinking oolong tea and cholesterol levels, as high cholesterol levels can be associated with an increased risk for heart disease.

They found that people who drank at least 10 ounces of oolong tea per week had lower risks of having high total cholesterol, triglyceride, and LDL or “bad” cholesterol levels. The same was also true of people who drank similar amounts of green and black teas.

People who had been consuming oolong tea for the longest time had lower total cholesterol, triglyceride, and LDL cholesterol levels.

In another study, Japanese men and women were studied for the impact of consuming coffee, green tea, black tea, and oolong tea on their risk of heart disease. Researchers found that men who drank 1 or more cups of oolong tea per day had a lower risk of heart disease.

Weight loss

study in mice showed that the animals receiving oolong tea extract while being fed a high fat, high sugar diet, gained less abdominal fat than mice on the same diet that did not receive the tea extract.

Green tea and black tea extracts also resulted in the less abdominal fat gain. The mice that received the green tea extract also consumed fewer calories.

study in overweight and obese Chinese adults looked at the effect of oolong tea consumption on body weight. Study participants drank 300 milliliters (mL) of oolong tea four times per day. After 6 weeks, more than half of the participants had lost more than 1 kilogram.

Cancer

Researchers in Taiwan examined the association between drinking tea and the risk of head and neck or throat cancer.

Each cup of oolong tea consumed per day equated to a 4 percent lower risk, but the result was not significant. Each cup of green tea consumed per day equated to a 6 percent lower risk for head and neck cancer, which was more significant.

Another study in Chinese women found that drinking green, black, or oolong tea was linked to a decreased risk of ovarian cancer.

However, according to the National Cancer Institute, there is not currently enough research to say for certain that drinking tea decreases cancer risk.

Diabetes

Some studies have shown that drinking 3 or more cups of tea per day is associated with a lower risk of type 2 diabetes.

However, studies specifically looking at oolong tea have had varied results.

In one study, healthy men drank almost 6 cups per day of oolong tea. At different times, they drank oolong tea that contained supplemental antioxidants, which were in the form of catechins or polyphenols. Each of the teas was consumed for 5 days. Researchers found that drinking oolong tea did not improve blood sugar or insulin levels.

Interestingly, one study found that working men who drank 2 or more cups of oolong tea per day had a higher risk of developing diabetes than men who consumed 1 cup of oolong tea per day or no oolong tea.

Dental health

Fluoride is an element that is often added to drinking water, toothpaste, and mouthwash to help prevent dental cavities.

Tea leaves naturally contain fluoride, so drinking oolong tea could help prevent cavities. Excess fluoride can be harmful, but drinking less than 1 liter of oolong tea per day is safe for most adults.

Other possible benefits:

While there is not enough current research to support the following benefits, drinking tea has also been associated with:

  • healthier gut bacteria
  • lower risk of Alzheimer’s disease
  • lower risk of Parkinson’s disease
  • natural defense from the sun’s ultraviolet rays
  • stronger bones

Studies that examined long-term consumption of oolong tea showed the greatest results. Although it is not a cure for any condition, drinking tea regularly appears to have numerous health benefits.

Risks and Considerations

Oolong Too much
Too much oolong can affect the absorption of iron into the blood.

Although oolong tea contains less caffeine than coffee, people who are sensitive to caffeine should still limit their intake.

Tea can decrease the amount of iron absorbed from plant foods. Also, some researchers found that young children who drank tea were more likely to have lower iron levels.

It may, therefore, be better to drink tea outside of meals to limit its impact on iron absorption. When consumed together at meals, eating foods rich in vitamin C can increase the amount of iron absorbed from plant foods.

Tea is a healthy beverage that has been consumed by people around the world for centuries. Oolong tea is a lesser known variety that may also provide health benefits. However, from some of the research reviewed above, drinking green tea may offer the most health advantages.

Bottled tea contains smaller amounts of beneficial polyphenols and may have excessive amounts of added sugar. If buying bottled teas, it may be better to look for ones that are unsweetened or to brew tea at home and sweeten it with a small amount of honey.

Oolong tea should be steeped for as long as possible to increase flavonoids, and people can consume 2-3 cups per day.

Cinnamon May Reduce the Harms of a High-Fat Diet

A diet high in fat is considered a major risk factor for cardiovascular disease, as it can lead to weight gain, diabetes, and other harmful conditions. New research, however, suggests that it may be possible to offset some of this risk by incorporating cinnamon in the diet.
Researchers suggest that cinnamon may offset some of the damage caused by a high-fat diet.

Researchers found that rats fed a high-fat diet supplemented with cinnamon for 12 weeks gained less weight and abdominal fat and had healthier blood levels of fat, sugar, and insulin when compared with rodents fed a high-fat diet without cinnamon.

Study co-author Vijaya Juturu, Ph.D., of OmniActive Health Technologies Inc in Morrison, NJ, and colleagues recently presented their findings at the American Heart Association’s Arteriosclerosis, Thrombosis and Vascular Biology/Peripheral Vascular Disease 2017 Scientific Sessions, held in Minneapolis, MN.

Cardiovascular disease (CVD) is an umbrella term for conditions that affect the heart and blood vessels, including heart attack, stroke, and heart disease.

Heart disease is the leading cause of death for men and women in the United States, killing around 610,000 people every year.

Diet plays a major role in CVD. An unhealthful diet – such as one high in fat – can cause obesity, type 2 diabetes, high cholesterol, and other conditions that raise the risk of poor cardiovascular health.

According to Juturu, research has shown that cinnamon – a spice derived from the bark of trees from the Cinnamomum genus – contains a polyphenol that has anti-inflammatory and antioxidant properties, which may reduce some of the risk factors for CVD caused by poor diet.

For their study, the researchers set out to investigate whether cinnamon might help to reduce the harms associated with a high-fat diet.

Cinnamon protects against inflammation, oxidative stress

For 12 weeks, the researchers fed rats a high-fat diet supplemented with cinnamon and compared them with rodents that were fed a high-fat diet without the spice (the controls).

The team found that rats whose diets were supplemented with cinnamon weighed less and developed less abdominal fat than those fed a high-fat diet without the spice. Rats fed a high-fat diet with cinnamon also had healthier blood glucose and insulin concentrations, as well as better lipid profiles, than the controls.

Additionally, the researchers found that rats that received cinnamon had fewer molecules associated with the storing of fat, as well as increased levels of anti-inflammatory and antioxidant molecules.

Antioxidants protect against oxidative stress,, which is an imbalance of free radicals that has been associated with numerous health conditions, including heart attack and heart disease.

Based on their findings, Juturu and colleagues believe that cinnamon may decrease the damaging effects of a high-fat diet.

The team concludes:

“These results suggest CNM [cinnamon] supplementation reduces hyperlipidemia, inflammation, and oxidative stress through activating transcription factors (SREBP-1c, LXR-α, NF-κB, and Nrf2) and anti-oxidative defense signaling pathway.”

Doctors Should Discuss Herbal Medication Use with Heart Disease Patients

Physicians should be well-versed in the herbal medications heart disease patients may take to be able to effectively discuss their clinical implications, potential benefits, and side effects – despite a lack of scientific evidence to support their use, according to a review paper published in the Journal of the American College of Cardiology.

Herbal medications do not require clinical studies before being marketed to consumers or formal approval from regulatory agencies, so their efficacy and safety are rarely proven. In the U.S., herbal medications can only be found unsafe by the Food and Drug Administration after they have caused harm. Still, they remain popular among heart disease patients for their potential cardiovascular benefits. A recent survey said 1 in every 5 people will take an herbal or dietary supplement in their lifetime.

Researchers in this review paper looked at 42 herbal medications that have a possible indication for treating one or more cardiovascular condition, including hypertension, heart failure, coronary artery disease, dyslipidemia, thromboembolic disorders or peripheral artery disease. They then selected 10 of the most commonly used in cardiovascular medicine to discuss possible indications, biological and clinical data, and safety concerns.

The researchers said that despite all the clinical evidence on these herbal medications, there is an overall lack of evidence available, and it is not always possible to clearly establish a cause-effect link between exposure to herbal medications and potential side effects.

They concluded that because of the popularity of these medications and the potential for drug interactions or other safety concerns, physicians should start a conversation around herbal medication use to effectively counsel their patients. Many patients don’t volunteer information on their herbal medication use to their doctor because they do not perceive them as drugs. Physicians are also unlikely to regularly gather correct information on their use. However, herbal medication use has been associated with poor adherence to conventional medications, which is a serious concern.

“Communicating with the patient is a crucial component of the process,” said Graziano Onder, MD, Ph.D., senior author of the review paper and an assistant professor in the department of geriatrics, neurosciences, and orthopedics of the Università Cattolica del Sacro Cuore in Rome. “The pros and cons of specifics herbal medications should be explained and their risk-benefit profile properly discussed.”

Researchers said physician education is an important consideration as well since the study of alternative medicine is not part of medical school curriculums in the U.S. Obtaining the necessary knowledge to provide better care for patients around the use of herbal medications is solely up to the physician.

“Physicians should improve their knowledge of herbal medications in order to adequately weigh the clinical implications related to their use,” Onder said.
