Coffee May Benefit Colorectal Cancer Patients

25 Jan

Coffee is one of the most consumed beverages around the globe, and many individuals can’t seem to start their day without a cup or two. Past research has identified several compounds present in coffee that can offer health benefits, and new research suggests that coffee intake can also help patients under treatment for colorectal cancer.

The study, published in September 2020 in JAMA Oncology, looked at the association of coffee intake and survival in patients with advanced or metastatic colorectal cancer. In the study, which included 1,171 patients (median age 59), participants kept track of their caffeinated and decaffeinated coffee consumption for five years. The researchers observed that participants who consumed two to three cups of coffee per day were not only more likely to survive but their cancer was less likely to progress. Additionally, those who consumed at least four cups a day had even better results. The study concluded that “Coffee consumption may be associated with reduced risk of disease progression and death in patients with advanced or metastatic colorectal cancer. Further research is warranted to elucidate underlying biological mechanisms.”

The longevity benefits aren’t limited to patients with advanced colorectal cancer. A 2015 study looked at the association of coffee consumption (both caffeinated and decaffeinated) with total and cause-specific mortality in three large prospective cohorts: 1) 74,890 women; 2) 93,054 women; and 3) 40,557 men. The research team’s analysis revealed that regular coffee drinkers (one to five cups a day) had a lower risk for early death, though those who frequently consumed more than five cups a day did not experience increased longevity.

Regular coffee drinkers often report that it improves their ability to think and focus, but are there any long-term cognitive benefits to coffee? Perhaps. In 2019, researchers used advanced imaging to look for amyloid plaque build-up, a characteristic of Alzheimer’s disease, in the brains of 411 seniors without cognitive impairment. When researchers separated the data based on the participants’ coffee habits, they observed that those who consumed two or more cups of coffee a day had lower amyloid levels in the brain, suggesting a reduced risk for Alzheimer’s disease. A review of past studies has shown coffee consumption to be associated with a reduced risk of developing many diseases including type 2 diabetes, liver cancer, endometrial cancer, lethal prostate cancer, basal cell carcinoma of the skin, neurological diseases, and cardiovascular disease when consumed in moderation. Doctors of chiropractic often encourage patients to adopt a healthier lifestyle, which includes consuming vital nutrients, vitamins, and minerals, and getting regular exercise. If you enjoy coffee and do so in moderation, the current data suggests it may provide benefits beyond helping you become more alert.

Benign Paroxysmal Positional Vertigo Management Strategies

21 Dec

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo, or dizziness, that is associated with movement of the head (though some motions may be more problematic than others) that goes away when movement ceases. Essentially, BPPV is caused by crystals becoming displaced within the semicircular canals (inner ear), which causes eddy currents in the fluid that circulates in the canals. Instead of the normal flow that bends small hair-like nerves in the same direction telling the brain that you’re standing, laying, running, etc., the brain is essentially given mixed messages of what position you’re in, resulting in a “sea-sickness” type of sensation.

There are several “canalith reposition maneuvers” available, and the choice of which maneuver to use depends on which canal(s) is affected. According to the Mayo Clinic, these maneuvers consist of several simple head movements, which can provide release in up to 80% of BPPV patients within a few treatment sessions, though the problem can recur.  

In an August 2020 study, researchers set out to determine whether vitamin D and calcium supplementation could prevent the recurrence of BPPV. A group of 518 BPPV patients from eight participating hospitals were provided with a twice daily 400 IU vitamin D and 500mg calcium carbonate supplement for a year. Another 532 BPPV patients served as a control group that did not receive a supplement.

The data show that patients in the supplement group were less likely to experience a recurrence in the following year (37.8% vs. 46.7%), especially those with low vitamin D levels at the start of the study. The researchers concluded that vitamin D and calcium can be considered in patients with frequent attacks of BPPV, especially when their blood level of vitamin D is low.

            Interestingly, another study published in August 2020 found that vitamin D deficiency may be associated with up to a 3.29 times increased risk for BPPV recurrence, giving individuals yet another reason to spend time in the sun, take a vitamin D supplement, and eat vitamin D-rich foods to improve their vitamin D status.

            A review of your health history and an examination can reveal if your vertigo/dizziness symptoms are indicative of BPPV. If so, your doctor of chiropractic can train you in the various canalith reposition maneuvers to relieve those frequently debilitating symptoms. He or she will also counsel you on nutritional supplementation and diet. As noted in the recent study, the recurrence rate of BPPV is high and the intake of vitamin D and calcium can significantly reduce that rate.

Health Optimization Strategies

23 Nov

Though some element of our overall wellbeing is defined by our genetics, there is a  lot you can do to live a long and healthy life. Here’s a short list:

  • Get enough sleep. While the average adult needs only seven to nine hours of sleep a night to feel rested, younger age groups usually require much more: infants (0-3 months): 14-17 hours/day; 4-11 months: 12-15 hours/day; toddlers: (1-2 years old) 11-14 hours/day; pre-school (3-5 years old): 10-13 hours/day; school age (6-13 years old): 9-11 hours/day; and teenagers (14-17 years old): 8-10 hours/day. An expectant mother may need additional sleep, especially early in the pregnancy.
  • Exercise at moderate intensity for at least 30 minutes a day (brisk walk, bike ride, jog, yoga, tai chi, etc.). Federal guidelines also recommend strength training the major muscle groups twice a week.
  • Avoid added sugars, sugary drinks, and processed foods. Eat more whole grains, fruits, and vegetables. Not only will it help you maintain a healthier body weight, but you’ll also improve the make-up of your gut microbiota, which can bolster your immune system.
  • Consider supplementation if your diet is deficient in important vitamins and minerals. For example, a 2017 study published in the journal Nutrients reported that vitamin C can enhance the production of B- and T-cells, which are related to the body’s ability to fight off infections. Moreover, the study noted that vitamin C deficiency is associated with impaired immunity resulting in higher susceptibility to infection.
  • When (not if) stress hits, take five slow, deep breaths (in your nose and out of your mouth). Consider mindful meditation or schedule relaxing activities into your day.
  • Engage in social networks (senior centers, church, and book clubs or go to plays, music events, and art galleries with a friend), preferably in person but virtually (phone or video chat) if that’s not feasible.
  • Laughing reduces stress hormones, boosts white blood cells, and keeps you healthy.
  • Wash your hands with soap and water regularly, use hand sanitizer regularly (if it’s not possible to wash your hands), don’t touch your eyes, nose, and mouth; cover your mouth with your arm when you sneeze, and stay home when you’re ill.
  • Spend time in the sun or take a vitamin D supplement. Studies show that individuals with poor vitamin D status may be at an increased risk for upper respiratory infection and impaired immune response.

Of course, if you experience musculoskeletal pain, like neck or back pain, schedule an appointment with your doctor of chiropractic. Typically, the sooner you seek care, the faster you’ll be able to return to your daily activities without pain.

The Benefits of Blocking Blue Light

22 Oct

The electromagnetic spectrum spans from gamma rays—which can be deadly—to the radio waves that flow in the air all around us without any effect. Between the ultraviolet and infrared sections of the spectrum is the most important wavelength for our eyes: visible light. But research indicates that blue light can be problematic in high doses—especially with our increasing use of electronic devices.

Both the sun and incandescent bulbs emits light in a broad range that our eyes have evolved to see. The light that emanates from our electronic devices may appear similar, but it’s concentrated in three main peaks of blue, green, and red. When using a phone or tablet, that means a greater than average amount of more energetic blue light is being sent to your eyes at a short distance and for (often) a prolonged period of time. Researchers have observed that this can cause the eyes to grow tired and dry out, which can lead to discomfort. Exposure to blue light at night can slow the production of the sleep hormone melatonin, resulting in sleep difficulties and the negative health effects associated with it.

To reduce the consequences of excessive blue light exposure, several tech companies have created blue light and nighttime filter settings that reduce the amount of blue light that comes from devices. Many websites and programs also offer a dark mode that reduces the amount of white on the screen, which means less light is emitted by the diodes. Users often report that these features are easier on the eyes.

While there is debate on the topic, excessive exposure to blue light may also lead to an increased risk for macular degeneration, a common cause of vision loss associated with damage to the photoreceptor cells in the retina. In laboratory studies, researchers have observed that when blue light interacts with the molecule retinal, it can lead to cell damage and even cell death. This effect did not occur with other forms of visible light. However, it’s important to note that this study was conducted in a laboratory setting and not on eyes themselves, so although the authors found a mechanism by which blue light plus retinal can cause cell damage, they’re not sure if this occurs in the eye itself.

Nonetheless, given the effect that prolonged screen use can have on eye fatigue and possible sleep interruption, it’s important to take breaks to rest the eyes and use filters or modes that reduce blue light (or wear glasses that block blue light).

Energy Boosting Tips

28 Sep

When fatigue hits during the day, many people will reach for a sugary snack or a caffeinated beverage. While these practices may lead to a quick, short burst of energy, the crash afterwards can leave one feeling even more tired. Let’s look at healthier methods to improve energy levels.

1) EAT BREAKFAST: Studies have shown that people who eat breakfast have less fatigue and stress than those who skip it. Avoid white flour/sugary options, like donuts. Instead try fruit and fiber-rich foods, like oatmeal, which help maintain satiety longer.

2) EXERCISE: A simple 5- to 10-minute walk or any quick bout of exercise can increase blood flow to the brain and enhance cognitive function.

3) SING/TALK: Singing opens specific brain pathways that can both elevate emotions and reduce stress hormone levels. Try it while driving or anytime you feel those eyelids dropping, but perhaps NOT at an office meeting! Like singing, talking stimulates areas of the brain to make us more alert.  

4) DRINK WATER: Feeling lethargic is a common symptom of dehydration. Consider drinking water throughout the day (such as eight 8-oz. glasses per day) as some experts have stated that by the time you feel thirsty, you may already be in a state of mild dehydration, which can also impair cognitive function and increase the risk for headache.

5) SUNSHINE: Spending time in the sun stimulates the production of energy-boosting vitamin D. A recent study showed that exposure to sunlight throughout the workday not only led to better sleep but also improved performance on cognitive tests.

6) SNACK: Try eating almonds and peanuts, which are high in magnesium and folic acid and essential for energy and cell production. Consuming protein and slow-burning carbs like bananas, peanut butter, or granola with fresh berries can also help maintain blood sugar levels. A scented spice, like cinnamon or peppermint, can also fight fatigue and make us more alert.

7) LAUGH: Listen to comedy or think of a recent funny experience and laugh out loud, if possible—it’s amazing how that stimulates certain centers in the brain to give you an energy boost.

8) GET MORE SLEEP: It seems obvious but sleeping less than seven hours a night is unhealthy and reduces the energy you have available during the day. Quality of sleep is important as well, so if you toss and turn or wake up a lot at night, consider a sleep study to assess for sleep apnea.

The Reason Blood Pressure May Rise in the Winter

24 Aug

A 2009 study that monitored over 8,800 elderly French adults found that an individual’s blood pressure can fluctuate with the seasons. In particular, the researchers observed that as temperatures fell, both systolic and diastolic blood pressure could rise to unhealthy levels, but they were unable to determine why.

However, a study published just five years later may have solved the mystery. The solution has to do with the molecule nitric oxide. Nitric oxide is a vasodilator, meaning that it causes the walls of blood vessels to relax and expand, with a resulting reduction in blood pressure.

Researchers have discovered that nitric oxide is stored in the dermal vasculature at levels much greater than are found circulating in the bloodstream. When exposed to long-wave ultraviolet (UVA) rays, the skin releases some of that stored nitric oxide into the bloodstream. Because individuals tend to spend less time in the sun during the winter months, there are fewer opportunities for the skin to release nitric oxide into the blood, dilate blood vessels, and moderate blood pressure. This may also help to explain why stroke and blood vessel rupture (aneurism) are more common in the winter months among the elderly.

How can one maintain healthier levels of nitric oxide in their bloodstream when it’s not convenient to spend time in the sunshine? The answers may be found in diet and exercise.

A 2018 study found that eating leafy greens and root vegetables and drinking beetroot juice effectively increased nitrate plasma (blood) levels for the purpose of enhancing exercise performance.

In 2020, researchers observed that schoolteachers in South Africa with greater physical fitness levels had higher levels of nitric oxide in their blood, as well as lower systolic and diastolic blood pressure readings. The research team concluded, “These results may suggest that even moderate physical activity could increase nitric oxide synthesis capacity, which in turn may mitigate the development of cardiovascular disease in this population.” 

The take home message is that to maintain a healthier blood pressure, consider getting plenty of sunshine, eating leafy green and root vegetables (or drink beetroot juice), and exercising!
