Health Benefits for Coffee Drinkers

Research based on 200 previous global studies indicates that frequent coffee drinkers are less likely to get diabetes, heart disease, dementia, and even some cancers. Those who drink three to four cups a day will, in fact, experience health benefits—and experience lower risks of premature death. 

To better understand the effects of coffee on health, Robin Poole—a public health specialist at Britain’s University of Southampton—led a research team in an ‘umbrella review’ of 201 studies based on observational research, and 17 studies based on clinical trials across the world. ‘Umbrella reviews’ consolidate previous analyses, in order to deliver a clearer summary of diverse research on a particular topic.

The research, published in the The BMJ, revealed that drinking coffee was consistently linked with a lower risk of death from all causes, including heart disease. The largest reduction in relative risk of premature death was seen in people consuming three cups a day, compared with non-coffee drinkers. Drinking coffee was also associated with a lower risk of several cancers, including prostate, endometrial, skin and liver cancer, as well as type-2 diabetes, gallstones and gout. The greatest benefit was seen for liver conditions, such as cirrhosis of the liver.

“What we can say is that people who already enjoy moderate amounts of coffee as part of their diet are most probably getting health benefits,” writes Poole. These findings should be reassuring for coffee drinkers; future studies will likely analyze the types and amounts of coffee that confer the maximum health benefits.

The Necessity of Nutrition

With over two-thirds of Americans considered to be overweight or obese, the global obesity epidemic shows no signs of slowing. As diabetes and cardiovascular disease are on the rise, in addition to spikes in other lifestyle-related disorders, it becomes increasingly critical to maintain education surrounding healthy living habits. Yet while physicians are generally considered to be reliable sources regarding nutrition, more than 50% of graduating medical students continue to rate their knowledge as ‘inadequate,’ and only one in eight patients receives counseling from their doctors on dietary health benefits.

A study found that the majority of cardiologists lack current, up-to-date education surrounding nutrition and diet. A report published by the American Journal of Medicine, authored by a dozen healthcare professionals in the United States and Spain, titled “A Deficiency of Nutrition Education and Practice in Cardiology” details that less than a third of cardiologists describe their nutrition knowledge as “mostly up to date” or better. Indeed, while the leading cause of premature death and disability in the United States is heart disease, most cardiologists report inadequate training in nutrition. “Using nutrition as medicine is probably one of the most cost effective ways to treat disease but is incredibly underutilized by healthcare providers,” explained Andrew Freeman, M.D., a cardiologist at National Jewish Health in Denver, and one of the study’s co-authors. “If we could empower healthcare providers with information on how to implement this in daily practice, we could transform healthcare rapidly, prevent healthcare cost explosions, and reduce morbidity and mortality.”

Ninety percent of cardiologists surveyed reported receiving no or minimal nutrition education during cardiovascular fellowship training; 59 percent reported no nutrition education during international medicine training; 31 percent reported no nutrition education throughout medical school. Almost two-thirds of all surveyed cardiologists reported spending three minutes or less per visit discussing nutrition with their patients.

Moreover, another study designed to quantify the required number of hours of nutrition education at U.S. medical schools, in addition to an investigation regarding the types of courses offered, reaffirmed the supposition that medical students receive an inadequate amount of nutrition education. Only 27% of surveyed schools required a course dedicated to nutrition; on average, U.S. medical schools only offer 19.6 hours of nutrition education—across four years of medical school. Other informal polls and anecdotes uphold the studies’ findings, as students assert that nutrition education throughout medical school is, at best, minimal.

Throughout the past several decades, there has been a push towards improving the medical nutrition education that students receive. With suboptimal knowledge about dietary habits, future physicians are selling both themselves and their patients very short. It is imperative to equip health practitioners with the necessary tools and information that they can utilize in their practices, ultimately addressing the root causes of real, pervasive problems. Medical schools have the burden of responsibility to arm their graduates with the tools to tackle the biggest, most acute global health challenges: including obesity and nutrition problems.

No More Pricks: Trading blood tests for tear tests?

Here at A4M, we are all about moving forward into the future of medical care. How many years have we been drawing blood to detect health and nutritional deficiencies in our makeup?
Too many.

We are actually starting to see that this may now change. We may have figured out that we may not need to be pricked by a needle to get tested.
A study now suggests that tears could be considered an alternate source of diagnostic fluid for testing for nutritional deficiencies.

Researchers from Michigan Technological University in partnership with UP Health System -Portage in Michigan have determined that tears are not only easier to produce than blood, but tears are also easier to work with when analyzing as a fluid.

Maryam Khaksari, study author and research specialist at Michigan Tech, said studies show that people with nutritional deficiencies blink more than those without deficiencies. “We hypothesized that nutrients are transferred to the living cells of your cornea through your tears,” Khaksari said. “We would like to translate the information we have for blood to tears. In this paper, we did show that there are correlations between vitamin concentrations in tears and blood – so it’s possible.”

The researchers involved in this study retrieved samples of both tears and blood from 15 different families that each had a four-month-old child. The samples taken from a child and a parent were then compared between tears and blood, infants and their parents, and against self-reported dietary intakes.

Multiple vitamins were all detected in both the tears and blood, and although Vitamin A was only found in the blood samples, researchers claim this is only the beginning. This project is the first step which proved vitamins are detectable in tears, and that they do correlate with blood levels. “Our goal was to seek the viability of establishing measurable vitamin concentrations in tears for nutritional assessments,” Khaksari said. “Your body cannot manufacture vitamins, and vitamins reflect available food sources in your body. That’s what makes them good indicators of nutritional health.”

We fully understand that this is only the start of the discussion regarding the trade of blood for tears, but we are very excited to follow this research and report back to all of our followers that there may be a day where we don’t have to have a needle draw blood to determine everything!
