When most people awaken, the first thing they grab is a cup of coffee or a cup of tea. You will also find a number of ice tea drinkers, as well as those who love ice coffee beverages, which have become quite popular. With both beverages being highly popular, we often hear the question, “Is tea better than coffee”, which is exactly what we wanted to address here in this article.

Okay, so is tea better than coffee and if so, why? The answer is yes, tea is better than coffee and we will explain why. Both beverages contain caffeine, a substance that helps get the day going but for individuals with a caffeine sensitivity problem, both coffee and tea would likely cause a problem. In addition, both coffee and tea are delicious. These drinks can be consumed as is or enhanced with cream, sugar, and honey, and so on. As you can see, tea and coffee have a lot in common but this is where the similarities begin to fade.

Now, for the question of is tea better than coffee, keep in mind that the type of tea makes a huge difference. Interestingly, different teas offer different benefits. For example, ginseng tea has been studies with results showing this type of tea can improve concentration and memory, boost a person’s reaction time, help fight off viral infections, reduce stress, and even improve circulation.

Then, you have black tea, also loaded with health benefits. For instance, black tea can prevent clogged arteries that lead to heart attack and stroke, this tea inhibits cancer growth, helps reduce inflammation, and is proven to neutralize many germs. Of course, green tea is a favorite, which also helps fight cancer, lowers high blood pressure, reduces bad cholesterol, and kills oral bacteria that causes plaque leading to tooth decay.

Although coffee tastes great, you can see the answer to the question, “Is tea better than coffee” is yes. Keep in mind that because of the caffeine makeup of coffee, most people would agree that coffee is better at providing a quick mental boost than most teas do. However, many teas contain antioxidants that work to protect the cellular structure of the body, leading to a healthier and longer life.

Again, coffee does have some health advantages over tea. In this case, studies show that coffee is a good preventative against liver cancer and that it lowers the chance of gallstones. Although these are certainly great reasons to drink coffee, we still believe that tea outranks coffee. In addition to the abovementioned benefits of tea, others include fighting off osteoporosis, reducing risk of kidney disease, providing relief from menstrual cramping and aching muscles, and calming the nerves.

The next time someone offers you coffee versus tea, we recommend you stop to thing of the age-old question, “Is tea better than coffee” to help you make the right choice. Of course, you can enjoy a good cup of coffee on occasion but perhaps you might be more apt to reach for tea instead.

Accepting food cravings and keeping them in check may be an important component of weight management, as per findings from the first six-month phase of a calorie-restriction study conducted at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University. Supplemental results from the Comprehensive Assessment of the Long-term Effects of Restricting Intake of Energy (CALERIE) trial provide new insights into food cravings, specific types of foods craved, and their role in weight control.

Cravings are really normal; almost everyone has them, says corresponding author Susan Roberts, PhD, director of the USDA HNRCAs Energy Metabolism Laboratory. At the start of the study, 91 percent of the participants reported having food cravings, which are defined as an intense desire to eat a specific food. Most people feel guilty about having food cravings, says Roberts, but the results of this study indicate that they are so normal that nobody needs to feel they are unusual in this respect.

In addition, the results indicate that cravings dont go away during dieting. In fact, 94 percent of the study participants reported cravings after six months of dieting. However,Roberts says, participants who lost a greater percentage of body weight gave in to their.

cravings less frequently. Allowing yourself to have the foods you crave, but doing so less frequently may be one of the most important keys to successful weight control, she adds.

Roberts and his colleagues found that successful weight loss was related not only to how often people gave in to their cravings, but also to the types of foods they craved. Participants with a higher percentage of weight loss actually craved foods with higher energy (calorie) density, compared with those who lost a lower percentage of body weight, says Roberts, who is also a professor at the Friedman School of Nutrition Science and Policy at Tufts University. Energy-dense foods, such as chocolate and some salty snacks, are those that pack the most calories per unit of volume, explains Cheryl Gilhooly, PhD, MPH, research dietitian and first author of the study, as in comparison to less energy-dense foods like fruits and vegetables, which have fewer calories per unit of volume.

These findings suggest, says Roberts, that cravings are for calories, not carbohydrate, as is widely assumed. What is usually called carbohydrate addiction should probably be relabeled as calorie addiction, she added. Some of the most usually craved foods among study participants were foods that have high sugar plus fat, such as chocolate, and salty snacks, such as chips and French fries. The craved foods do have carbohydrate, but they also have fat, and some protein, too. The most identifiable thing about the foods people crave is that they are highly dense in calories, Roberts deduces.

The study, which was part of the one-year CALERIE trial, involved 32 overweight but otherwise healthy women, 20 to 42 years of age, who were randomly assigned to two diets that differed in glycemic load, a measurement of how quickly the carbohydrates in a persons diet are converted to blood sugar.

Participants completed food craving questionnaires that assessed the foods craved, the frequency and strength of cravings, and how often cravings led to eating the desired food. Scientists collected information from these questionnaires, along with data from dietary intake records and measures of weight change over time. Primary results from the CALERIE study were reported in an earlier issue of Friedman Nutrition Notes, available at http://nutrition.tufts.edu/news/notes/2007-03.html.

This is the first study of long-term changes in food cravings in a calorie-restriction program, Roberts says. If individuals understand that they can expect cravings and that those cravings will be for calorie-dense foods, it might help in their weight management.

One thing to do is to substitute foods that taste similar but have fewer calories, since the craving can be satisfied by related tastes.

Roberts and his colleagues conclude that cravings for energy-dense foods are common. Eventhough they caution that additional long-term studies are needed to confirm their findings, they write that their results suggest that people attempting to lose weight and maintain weight loss may benefit from advice to accept that food cravings may not decrease in frequency. Controlling the frequency of giving in to cravings, rather than suppressing them, they say, may be an important area of emphasis in future weight control programs.

Taking a break in the middle of your workout may metabolize more fat than exercising without stopping, as per a recent study in Japan. Scientists conducted the first known study to compare these two exercise methodsexercising continually in one long bout versus breaking up the same workout with a rest period. The findings could change the way we approach exercise. Who wouldnt want to take a breather for that" .

A number of people believe prolonged exercise will be optimal in order to reduce body fat, but our study has shown that repetitions of shorter exercise may cause enhancements of fat mobilization and utilization during and after the exercise. These findings will be informative about the design of [future] exercise regimens, said lead researcher Kazushige Goto, Ph.D. Most people are reluctant to perform a single bout of prolonged exercise. The repeated exercise with shorter bouts of exercise will be a great help [in keeping up with fitness].

This finding is part of a study entitled Enhancement of fat metabolism by repeated bouts of moderate endurance exercise, found in the June 2007 edition of the Journal of Applied Physiology, which is published by the American Physiological Society. It was conducted by Kazushige Goto, of both the Department of Life Sciences, Graduate School of Arts and Sciences, University of Tokyo, Komaba, Tokyo, Japan and the Institute of Sports Medicine, Bispebjerg Hospital, Copenhagen, Denmark; Naokata Ishii, of the Department of Life Sciences, Graduate School of Arts and Sciences, University of Tokyo, Komaba, Tokyo, Japan; and Ayuko Mizuno and Kaoru Takamatsu, both of the Institute of Health and Sport Sciences, University of Tsukuba, Tsukuba, Ibaraki, Japan.

Summary of Methodology
The scientists used seven healthy (avg. body mass: 66.1, percentage fat: 17.6) men with an average age of 25 who were physically active and familiar with exercise and had them perform three separate trials:.

• one single bout of 60-min exercise followed with a 60-min recovery period (Single).
  
• two bouts of 30-min exercise with a 20-min rest after the first 30-min bout, along with a 60-min recovery period at the end (Repeated).
  
• one 60-min rest period (Control).
  

The men performed each trial at the same time of day after fasting overnight. They exercised on a single ergometer (cycling machine) at the usually recommended exercise prescription of 60% maximum oxygen intake. The recovery and rest periods were conducted while the subjects sat in chairs. Blood samples were taken every 15 minutes during the exercise and every 30 minutes during the recovery period. Their respiratory gas and heart rates were monitored continuously throughout the trial.

Summary of Results
The Repeated trial showed a greater amount of lipolysis (fat breakdown) than did the Single trial. This Repeated trial also had a pronounced increase in free fatty acids and glycerol (chemical compounds that are released when stored fat is used) concentrations in the final 15 minutes of exercise, whereas these concentrations only progressively increased throughout the Single trial. Also, the second half of the Repeated trial showed a significantly greater epinephrine response while also having a rapid decrease in insulin concentration as a result of lower plasma glucose. This combination of high epinephrine and low insulin concentration may have also increased the lipolysis. There was also enhanced fat oxidation in the recovery period of the Repeated trial than in the Single trial, but this result may be because the free fatty acids concentration was already high before the recovery period.

Conclusions
The American College of Sports Medicine recommends moderate exercise for the duration of 45 to 60 minutes to ensure a sufficient amount of energy is depleted in obese individuals. This has caused a greater focus on extending exercise sessions in order to burn more fat. However, this study shows that this method may not be the most effective way to enhance fat metabolism, as splitting up a long bout of exercise with a rest period burns more fat than a continuous bout of exercise. This study could help with the practical application of implementing new exercise methods in order to better manage and control weight in individuals in the future. However, Goto and his team of scientists plan on conducting further studies in order to explore the results in a variety of exercise durations as well as in different types of individuals.

Using selective cannabinoid 1 (CB1) receptor antagonists such as rimonabant at a dose of 20 mg per day can help people quit smoking, can help them to remain abstinent, and can help prevent the weight gain that so often accompanies attempts at stopping smoking. The lower dose of 5mg, however, was not shown to be effective, as per a Cochrane Systematic Review.

Smoking tobacco sends nicotine into the blood stream, and this chemical disrupts the endocannabinoid system, part of the hormonal control mechanism in the brain that controls energy balance and food intake. Over time the body alters the nature of its energy mechanism to compensate for this effect. Stopping smoking removes the nicotine and once again disturbs the mechanism, adding to the withdrawal symptoms and leaving a person prone to put on weight.

One potential way of preventing this is to take a drug that blocks the receptor that is involved in nicotines action in the brain the cannabinoid 1 receptor. These CB1 receptor antagonists could therefore form part of a therapeutic programme aimed at helping individuals quit smoking, eventhough this drug has still not been approved as a smoking cessation therapy in the USA or in Europe.

To see whether there was evidence that these receptor antagonists work two Cochrane Researchers, Kate Cahill who works at the Department of Primary Care in the University of Oxford and Michael Ussher who works at St Georges, University of London, searched the published and unpublished literature for relevant research projects. They found three trials that involved a total of 1567 smokers and 1661 people who had recently quit smoking. Analysing the data showed that the effect of the drug depended on the dose used:


Quitting with 20mg rimonabant:
People given 20 mg rimonabant increased by 50% their odds of remaining abstinent compared with those on placebo. Smokers who had quit while using 20mg rimonabant increased by 50% their odds of staying abstinent if they continued taking either 5mg or 20mg rimonabant, compared with those who moved to placebo therapy after quitting.


Quitting with 5mg rimonabant:
People who wanted to quit appeared to gain no benefit from 5 mg rimonabant therapy. Furthermore the people who did manage to quit using this lower dose were equally likely to remain abstinent whether they continued with rimonabant therapy or moved to a placebo.


Weight gain:
Weight gain appeared to be significantly lower in people who quit while using 20 mg rimonabant than those taking either 5 mg rimonabant or placebo. The differences in weight between the groups appeared to be maintained through longest follow-up. This beneficial effect was more evident in overweight or obese smokers than in those of normal weight.

From the preliminary data that we found it appears that 20mg rimonabant may significantly increase a persons likelihood of quitting and may also reduce the amount of weight that they gain, says Cahill.

You have a greater possibility of losing weight if you eat a diet that is high in foods like lentils that release energy slowly once they have been consumed, rather than one that is high in foods that rapidly release sugar into the blood stream such as white bread, a Cochrane Systematic Review has concluded.

When foods are eaten the body breaks them down into their components, and one component will be sugar. Different foods break down at different rates. Lentils, for instance, generate a long, gentle release of sugars, while foods like white bread send a sudden rush of sugar into the blood stream. Foods that release sugars rapidly are said to have a high glycaemic index those that release it slowly have a low glycaemic index.

A team of Cochrane Scientists set out to search for carefully conducted research trials that looked at the effects of eating high and low glycaemic index foods. They found six randomised controlled trials that involved a total of 202 participants. The trials ran for between five weeks and six months.

Their conclusion was that people eating low glycaemic index diets lost a mean of one kilogram more than those on similar energy high glycaemic index diets.

Low glycaemic index diets appear to be especially effective for people who are obese, says lead author Dr Diana Thomas, the Scientific Director of the Centre for Evidence Based Paediatrics Gastroenterology and Nutrition, in Westmead, Australia.

It may be easier to adhere to a low glycaemic index diet than a conventional weight loss diet, since there is less need to restrict the intake of food so long as the carbohydrates consumed have a low glycaemic index, says Thomas.
