I would recommend going for plain organic green tea

Green tea has been investigated and researched to determine its medical and health related benefits. It has been claimed to reduce the chance of certain cancer, heart disease, improve ratio of HDL/LDL cholesterol, increase bone density and much more. Many of the listed benefits attributed to green tea are of anti ageing nature, and are related to prevention of conditions typical to the ageing population. In the past decade, green tea has been associated with weight loss too.
Basically, there are two ways to control weight: reduction of food consumption (energy intake) or increasing energy expenditure (EE). Fat oxidation (fat metabolism) and thermogenesis (heat generation) in the body are under the control of the Sympathetic Nervous System (SNS) – the “fight or flight” branch of the nervous system. Just before any activity, the SNS is activated to produce the energy needed for the mission, this process includes activation of chain reactions that process glucose and fatty acids to release energy needed for the activity or for increasing body temperature. Triggering of the SNS involves neurotransmitters like norepinephrin which is released by the brain and by the SNS and triggers the chain reactions in the cells it attaches to. Since increasing metabolic rate and increasing temperature requires energy, it makes sense to try and target the SNS path for the sake of “burning energy” hence weight control.
Green tea is rich in Flavonoids, particularly tea catechins, which have been tested to have an inhibiting effect on the enzyme that breaks down the neurotransmitter and hormone mentioned above norepinephrin. In addition, Catechines increase insulin sensitivity, thus increasing glucose uptake within the skeletal muscles.
A study conducted at The University of Birmingham, UK, examined the effect of green tea extract on fat oxidation rate and on glucose tolerance during moderate intensity cycling in healthy men.
The study results exhibited a 17% increase in the oxidation rate of fat compared to the control group treated with placebo. The study also demonstrated an increase in Insulin sensitivity therefore, less insulin is needed to control glucose blood level, hence more glucose can be “processed” with less insulin (keeping glucose blood level lower with less insulin).
This means that consuming green tea will actually cause one to “burn” more fat while exercising and at rest.
This study is one of several that demonstrate the effectiveness of green tea for increasing the rate of fat metabolism. A different study demonstrated a 30% increase in metabolism rate during rest when green tea is consumed.
If you plan to “shape up” in a healthy manner, without starving yourself, and by increasing physical activity, it is a good idea to also add green tea to your diet. However, losing weight will not necessarily improve skin texture and appearance. It is a good idea to combine diet and lifestyle changes with existing technologies that target specific aesthetic issues, like cellulite, that cannot be improved by diet, green tea or exercise. Combining strong will with the help of existing technologies can also increase the incentive to diet as the results will be faster and better.
So, next time you need to choose a tea bag from a variety of existing beverages, select the green tea package and enjoy the healthy outcome. (I would recommend going for plain organic green tea, without flavors.)

“An atom or molecule having at least one unpaired electron: free radicals are usually very reactive and unstable, and can damage healthy body cells “.

One group of free radicals which is a byproduct of mitochondrial oxygen metabolism processes is Reactive Oxygen Species (ROS).  The ROS group always contains Oxygen or Per Oxides and is highly unstable. ROS can also be generated as a result of ionizing radiation such as UV radiation.

Free radicals are constantly created in the body during normal metabolism, ROS play a major role in inter cell communication that govern basic cell activities and coordinates the cell’s reactions to its micro environment, for example, initiating the tissue healing process in cases of injury. They are also deployed by the immune system as a way to attack and kill harmful bacteria such as Acne bacteria, the reactive oxygen – O₂^- molecule is highly toxic and is actually deployed to destroy these bacteria and it is also an important component of “cell suicide” needed to remove cancerous cell, damaged cells or cells whose life span had reached its end.

The body deals with the free radicals, more specifically ROS, via specific enzymes that break them down or neutralize them or through Antioxidants such as vitamins C and E, Uric acid and more.  Antioxidants prevent oxidative reactions, often by scavenging ROS before they can damage cells.

Normally, the body can handle ROS, but if antioxidants are unavailable, or if the ROS production becomes excessive, damage can occur which is labeled “Oxidative Stress”. Of particular importance is that ROS damage accumulates with age. This can be as a result of increased ROS production combined with a decrease in cellular Anti Oxidant activity.

The market is flooded with antioxidants for anti aging in all forms, from specific juices, extracts and pills. It is a heavily used term when it comes to food advertising and of course in anti aging cosmetics.

But are antioxidents always good for you? Analysis of data from many studies demonstrated that use of large quantities of anti oxidants can actually cause harm and shorten life span. It can also interfere with cancer treatment and prevent the recovery process after strenuous exercise as the ROS actually remove damaged and cancerous cells.

Free Radicals do cause acceleration of skin aging. Exposure to UV, stress, smoking and alcohol can increase ROS levels in the skin. The free radicals will altar the structure of our proteins, therefore damaging the collagen and weakening cellular structure. Unfortunately research has not demonstrated that ingestion or topical use of Antioxidants can prevent or eliminate wrinkles or other effects of aging skin. Merely taking antioxidant supplements will not correct the loss of skin elasticity or make the facial skin look younger.

So what can be done to reduce the affect of free radicals on the aging skin?

First, avoid UV damage by avoiding exposure to sunlight during dangerous hours in addition always apply a sunscreen when out in daylight.  Avoid smoking and large quantities of alcohol. Consume a diet with abundant quantities of vegetables and some fruit (too much sugar is also not beneficial to skin), and find ways to reduce your stress levels.

One way of repairing the damage to the skin and to induce collagen regeneration is via treatments using the TriPollar RF technology. This treatment will stimulate the fibroblast to generate new collagen fibers and to produce a thicker and denser dermal layer therefore reducing the visible signs of aging skin caused by the aging process and by exposure to free radicals.
