Nutrition Spotlight: Caffeine and L-theanine in Tea

2 Jan

According to a Unilever study recently reported in a Food Navigator-USA article, there is evidence to support the notion that compounds in tea, primarily caffeine and L-theanine, can be beneficial for one’s mood and mental focus.

Despite the European Food Safety Authority’s recent rejections of two Unilever health claims petitions (13.1 and 13.5) which linked black tea consumption to improved mental focus, the company is continuing its extensive research on the many benefits of tea consumption. Suzanne Einother and Vanessa Martens, employed at Unilever Research and Development, Vlaardingen (the Netherlands), are responsible for a recent review in the American Journal of Clinical Nutrition which, concerning a number of studies of tea consumption, notes “particularly consistent evidence for improved attention” throughout. They added that tea “consistently improved self-reported alertness and arousal” among subjects.

“These studies,” they said, “showed the validity of laboratory findings by supporting the idea that tea consumption has acute benefits on both mood and performance in real-life situations.”

The review was first formally presented on September 19th, 2012, at the Fifth International Scientific Symposium on Tea and Human Health in Washington, D.C.

Scientific research of tea has long focused on green tea, the benefits of which are well-documented and include improving oral and cardiovascular health, aiding in weight-management and reducing the risks of Alzheimer’s disease and some forms of cancer.

Black tea is simply green tea which is oxidized by fermentation, and contains between 3% and 10% of water-extractable polyphenols; original green tea, by comparison, contains between 30% and 40%. Fresh tea leaves contain four primary extractable polyphenols: epicatechin, epicatechin gallate, epigallocatechin and epigallocatechin gallate.

Unilever’s research, however, has focused more on L-theanine, an amino acid extracted from tea leaves, and caffeine. L-theanine is believed to help reduce stress while improving one’s quality of sleep. Since it is found in very low concentrations (less than 2%) in tea leaves, drinking tea cannot deliver effective dosage levels of 100 to 200 milligrams per day.

In the past, L-theanine has been linked to other various health effects, including improved attention, relaxation and certain “neuro-protective” effects. For example, it has been suggested that the amino acid is responsible for increased alpha activity during rest (as shown in EEG models), which can improve relaxation.

In the new review, Einother and Martens used data from randomized control trials focusing on tea’s effects on attention and mood.

“From the totality of research on tea summarized,” they wrote, “[…] it can be concluded that consumption of black tea may improve attention and self-reported alertness. These conclusions are further supported by studies on caffeine and on theanine and caffeine in combination.”

They are quite clear, however, about the pockets of uncertainty which remain for the time being: “Research on the benefits of tea is promising for attention and alertness, although questions remain regarding the scope and magnitude of impact as well as the sensitivity of different individuals. Whereas the bioavailability of both caffeine and theanine has been established, as well as the [suggested] mechanisms of action in the brain, they extent to which they actually cross the blood-brain barrier in humans and how much this is associated with [individual] changes in subsequent performance and mood measures are as yet unknown.”



Ingredient Spotlight: Benefits of Beetroot Juice

27 Dec

A Nutra-Ingredients article has recently reported the findings of a study of nitrate-rich beetroot juice; in a study using trained female runners, it was determined that drinking the juice for four days leading up to a running time-trial could greatly improve the runner’s performance.

As little as 140 milliliters per day of beetroot juice proved beneficial for systolic blood pressure and, in turn, a runner’s 5-kilometer performance, as determined by scientists at Sheffield Hallam University.

“Although not statistically significant,” they wrote, “these results suggest beetroot juice supplementation improved 5-km time trial performance over PLA by 31 s (2.4%). Athletes should consider ingesting beetroot juice to improve 5-km running performance.”

The study of beetroot juice and its potential nutritional and cardiovascular benefits has gained momentum in recent years, especially in the United Kingdom. In past studies, scientists from the University of Exeter (U.K.) found that beetroot juice could help individuals increase stamina and exercise for as much as 16% longer; scientists at the University of Maastricht have noted similar improvements in performance among cyclists. Publications in the Journal of Applied Psychology have suggested that the juice’s nitrate content, which helps reduce oxygen uptake, may be responsible for easing [quite effectively] the “tiring effect” of exercising.

That particular study was led by Professor Andy Jones, who offered a brief summary: “Our study is the first to show that nitrate-rich food can increase exercise endurance. We were amazed by the effects of beetroot juice on oxygen uptake because these effects cannot be achieved by any other known means, including training.”

In the new study, led by Robyn Lancely and her co-workers, a double-blind “crossover design” with repeated measures a two-week washout period was used to determine whether supplementation of beetroot juice would affect 5-km running time-trial performance.

Eleven trained female runners with an average age of 20 were assigned to receive 140 mL of the juice per day, as compared to no supplementation and a placebo. While there were no major differences in systolic blood pressure among the groups, the researchers identified a trend toward reductions following consumption of the juice; those who consumed it had an average value of 114 mmHg, compared to 122 mmHg for the control intervention and 120 mmHg for the placebo intervention.

“One km split times were similar between conditions except for the 2nd km where beetroot juice was faster than control by 16 seconds and placebo by 12 seconds.”


Power Brands Reviews: Recycling in the Beverage Industry

24 Dec

A recent survey led by Research Data + Insights and reported in an Environmental Leader article has shed light on the role consumers expect companies to play in recycling.

Of over 1,000 American adults surveyed, an overwhelming 86% said they expect food and beverage brands to work continuously on improving the recyclability of their packages. Many also indicated that they consult the products they purchase for environmental information before consulting other resources. About 76% of adults said they determine a package’s recyclability by looking at the package itself; the second most popular way is to consult the company’s website (33%), followed by 26% who consult the consumer’s city website.

Also, 45% of the adults claimed that their loyalty to a food/beverage company is affected by that company’s involvement in environmental causes, strengthening the common belief that environmental effort can improve consumer loyalty.

According to Jason Pelz, VP of Environment at Tetra Pak North America and VP of Recycling Projects at the Carton Council of North America, the survey should certainly encourage food/beverage brands to use the “recycling logo” on cartons; it not only proclaims the cartons are recyclable, but also provides the Recycle Cartons website (recyclecartons.com) where consumers can learn what cartons are accepted in their local recycling programs.

The Carton Council of North America, according to Pelz, actively encourages brands to use their packaging to “spread the word,” as well as expand their advertising to social media outlets – which provide endless marketing opportunities – and other websites.

The recycling of aluminum beverage containers at the industry level has been on an upward trend in the U.S. for decades, with a strong rate of 67% reported just last year. This is according to data published by the Aluminum Association, the Can Manufacturers Institute (CMI) and the Institute of Scrap Recycling Industries (ISRI).

The 67% rate reported in 2012 is, according to the three groups, the highest overall recycling rate since the early 1990s, and the second-highest since 1972 when the survey began. The groups say this rate marks tremendous progress towards their goal of a 75% recycling rate by 2015.


Official 2014 Winter Olympics Protein Drink Named

20 Dec

The Chicago Business Journal has reported that “Core Power” will be named the official protein drink of the 2014 Winter Olympics, which are set to be held in Sochi.

Core Power is a milk-based sports recovery/protein drink which launched nationwide in July of this year. It is produced by Fairlife LLC, a startup founded in 2012 and based in Chicago.

The honor includes a line of limited-edition Core Power bottles featuring four potential 2014 Team USA athletes, who will also promote the beverage across social media platforms. The bottles will hit the shelves in January 2014.

The selected American-born athletes to appear on the bottles are aerial skier Emily Cook, bobsledder Jazmine Fenlator and slope-style snowboarders Eric Willett and Jordie Karlinski. Steve Jones, Chief Executive of Fairlife, recently expressed his gratitude for the coming worldwide exposure in a public statement: “Our team has given it their all to develop a superior sports recovery drink and get it into the hands of athletes and active individuals across the country. This Sochi 2014 opportunity is humbling and motivating to us all.”

Core Power’s communications director Anders Porter added, “Just four years ago, it was only a handful of us, introducing people to Core Power out of a small office apartment in Austin, Texas. We’re very excited to bring our startup to the Sochi 2014 stage.

The milk from which Core Power is based comes from “Select Milk Producers,” a network of over ninety dairy farms which are all family-owned. Mike and Sue McCloskey, the founders of Fairlife, said they started the company with a goal of “revolutionizing the dairy industry and further invigorating the growing health and wellness category.” They also claim to have a number of new products [in addition to Core Power] which are set to be marketed and sold nationwide.


Power Brands Review: Coffee Consumption Trends

27 Sep

The National Coffee Association has recently published its 2013 “National Coffee Drinking Trends” report, which found that single-cup growth and coffee consumption have both increased in the past year. The study also found that consumption habits were stronger among Hispanic Americans than in other groups.

The NCA has conducted the study annually since 1950. This year’s study used a sample of 2,840 nationally-representative adults who filled out an online survey.

Of the U.S. adults who were polled, an incredible 83% said that they drank coffee in the past day, a 5% increase from last year. Daily consumption has been steady at around 63%, while consumption at least once a week increased slightly to 75%.

Power Brands has also noted single-cup growth in the last two years. Of American adults polled, 12% now own a single-cup brewer, an increase from 10% in 2012 and 7% in 2011. Awareness of single-cup brewers also increased to 82%, from 71% in 2012.

The high-consumption trend among Hispanic Americans was first identified last year by the NCA when it improved its ethnic sampling to represent minority groups more accurately. Of all adult Hispanic Americans polled this year, 76% said they drank coffee yesterday, compared to 64% of Caucasian Americans and 47% of African Americans.

According to Power Brands, the 2013 statistics are more “on par” with statistics from earlier years, which may suggest that the declining rates indicate volatility rather than softening in these particular segments.

The new research also found that 31% of those polled drank a “gourmet” coffee beverage. Traditional coffee consumption was 49%, a 7% decrease from the 2012 rate of 56%.

Past-day consumption in the category of espresso-based beverages was 24% among Hispanic Americans, 12% for African Americans and 10% among Caucasian Americans. In the age group of 18-24, overall daily consumption of coffee is at 41%, a decrease from 50% last year, and for those 25-39, consumption is at 59%, a slight decrease from 63%. Daily consumption among those 60 or older is on the rise, according to Power Brands, particularly in gourmet varieties. Daily consumption in that cohort is at 24%, a 5% increase from last year.

“NCA research finds that American coffee consumption continues to trend upward as consumers respond to variety and convenience,” said NCA’s president and chief executive, Robert F. Nelson. “Building on existing market enthusiasm, changing U.S. demographics and single-cup brewing may be adding momentum to already-enthusiastic consumer engagement.”

Power Brands Reviews: Dairy May Help Protect Muscle Mass

16 Sep

A recent article on the daily Rx reports that dairy products may play a role in preserving muscle mass says Power Brands, a leading beverage industry expert. The article ‘Got Dairy?’ reports that eating and drinking more dairy products may help protect the elderly from losing muscle mass. When you lose muscle mass, adds Power Brands, you are more prone to fractures and other similar injuries.

In actual fact, a current study found that older women who ate more dairy had greater physical performance and more muscle mass compared to woman who ate less dairy. The research was directed by Kun Zhu, PhD, in the Department of Endocrinology and Diabetes in Sir Charles Gardiner Hospital in Nedlands, Western Australia. There were 1,456 women between the ages of 70 and 85 that were tested. The researchers study involved examining the results of dairy intake and any association with physical performance and body composition.

The study involved measuring daily consumption using a food frequency survey. According to the daily Rx article, participants reported how much dairy they consumed in the last 12 months plus portion sizes. Dairy includes milk, cheese and yogurt, adds Power Brands.

The participants were then placed in one of three categories: more than 2.2 servings per day, 1.5 to 2.2 servings per day and less than 1.5 servings per day. In addition; height, body weight, BMI (body mass index) and body composition (lean and fat mass) measurements were taken. Rendering the daily Rx article, lean mass was categorized as the weight of everything in the body except for the weight of the head, bones and fat.

The researchers determined physical performance by measuring mobility (movement) and hand grip strength. Participants also reported the number of falls they had within the past three months. A participants smoking status and physical activity were also analyzed in the research.

Overall Findings

The researchers found that women who had 1.5 or more servings of dairy per day had considerably greater skeletal muscle mass  and whole body lean mass than women who had less than 1.5 servings per day. The researchers also found that hand grip strength was greater in women who had 2.2 servings of dairy a day compared to women who had less than 2.2 servings of dairy per day.

The study also concluded that there was no association between dairy intake and the amount of time it took to complete a mobility test. As well, there was no significant association found between dairy intake and number of falls.

Other Professional Input


Deborah Gordon, MD, a preventive medicine and nutrition expert not associated with the research told dailyRX, “There are a number of fascinating connections that appear in the details of this study”. Her conclusions are as follows:

  • Women who consumed more dairy (712 grams or around 25 ounces) were quite different than the group of women who consumed the lowest amount of dairy (210 grams or about 7.4 ounces)
  • Dairy lovers as a group ate more calories, fat and protein – the protein difference being primarily in dairy protein.
  • Dairy lovers were less likely to drink regularly and engaged in significantly more physical activity than the dairy minimizers

Dr. Gordon explained that some degree of sarcopenia (muscle loss) is unavoidable with aging. However, Dr. Gordon added that the extent to which muscle loss can be minimized and possibly reversed is in correlation to how vigorous and energetic she is as she ages. Dr. Gordon concludes that the study suggests woman who have a healthy appetite and partake in regular physical activity are investing in their sturdiness as they aging.

Overall Conclusion on Study

Based on their findings, dairy may be connected to better physical performance and more lean mass in older women. For further reading you can find full details of the study online in the Journal of the Academy of Nutrition and Dietetics.

Power Brands Reviews Water and Weight Loss

15 Aug

According to the beverage consultants at Power Brands, a group of past studies have collectively shown that dieters who drink more water tend to have more significant weight loss.

For instance, in one study dieters were asked to drink water before a meal. “The water enhanced the weight loss,” according to Brenda Davey, a Virginia Tech professor who was part of the studies.

However, researchers insist there is still not enough evidence to say with certainty that drinking more water will help a person lose weight.

The new review of the studies was led by Rebecca Muckelbauer, a researcher from the Berlin School of Public Health and the Charité University Medical Center Berlin. Since she is a nutrition researcher, she is often asked about whether drinking water will contribute to weight loss, and so she decided, along with her colleagues, to analyze a total of eleven studies on weight and water consumption.

According to Power Brands Consulting, three of the studies positively linked greater weight loss to increased water-intake among the dieters.

One of the studies conducted by Davy’s group found that middle-aged adults who drank two cups of water before a meal lost, on average, four pounds more than those who did not consume extra water. Another study found that women who drank less than one liter of water a day lost less weight than women who drank more.

“Drinking water itself increases energy expenditure of your body,” Muckelbauer told Reuters Health. “It has an energy-consuming effect. This is not well studied.”

The adult recommendations from the Institute of Medicine are 125 ounces for men and 91 ounces for women daily, which is between 2.7 and 3.7 liters.

Not all of the studies showed a positive correlation, however. “We don’t have conclusive evidence that increasing water intake reduces weight,” said Davy, “but there are certainly other benefits to increasing our intake.” Power Brands notes that Americans drink about 400 to 500 calories per day from beverages other than water, so replacing those beverages with water is always a healthy option.

“There’s not a lot of risk for recommending [increased water intake] for individuals,” Davy said.
