Let's focus on the benefits of loose leaf tea as they relate to physiology, mood, cognitive function and social mores.
Tea Antioxidants and Free Radicals
Tea contains chemicals called polyphenols or catechins that are antioxidants. Vitamin C is perhaps the most well-known antioxidant. Antioxidants are molecules that attach and overpower free radicals. Humans convert (oxidation) food to energy and daily create free radicals. Too many free radicals inside our bodies from poor eating habits, general pollution, and exposure to certain chemicals or radiation, smoking and stress can create free radicals also.
With unpaired electrons in their atomic structure, free radicals are extremely reactive and try to form bonds with other atoms and molecules. Once successful, its victim is now an electron short and will aggressively try to form a bond with another molecule, causing a cascade effect. The casualty, mitochondria, nerve cells, DNA/RNA, proteins, fats or cellular membranes now begins to malfunction. Unbridled, this degenerative process can bring on chronic diseases like cancer, heart disease, severe and chronic allergies, autoimmune diseases or premature aging.
Polyphenols are Anti-carcinogenic, Anti-bacterial and Anti-viral
Tea polyphenols will adhere to melanomas accelerating death (apoptosis). Polyphenols also elevate UDP-glucuronosyl transferase activity in animal tests which could sustain the removal of human drugs, dietary substances, toxins and hormones all precursors of degenerative, chronic, debilitating diseases.
Polyphenols have been evidenced to obliterate Gram-positive bacteria while ignoring Gram-negative. 100 years ago, the British Army understood the benefits of loose leaf tea and filled water bottles with brewed black tea to prevent and control soldier infections.
As an antiviral agent, polyphenols have been reported to inhibit the enzymes that allow viruses to become established in a host cell.
Studies have shown that tea can improve the flexibility of arteries and increase the diameter of such vessels called flow-mediated dilation (FMD). However, studies show heat medication may become ineffective with excessive tea drinking.
Osteoporosis is a degenerative disease in which bone re-absorbing cells, Osteoclasts overpower the bone forming cells Osteoblasts. Maintaining bone strength and density is an ongoing balance and dance between the two cell types. Though mechanisms are still unproven, it is suggested that the various tea polyphenols restore balance either by apoptosis of osteoclasts and by neutralizing hormones that promote osteoclast growth.
Obesity Loss and Diabetes
Tea consumption consumed regularly results diminished body fat and slimmer waists than the control group. One mechanism of control, gaining acceptance, is that the polyphenols inhibit the production of AGE’s (Advanced Glycation Endproducts). AGE’s have destructive capabilities similar to those of free radicals. AGE’s form normally in the body as a result of regular metabolic processes and the body removes them. However, should the AGE’s accumulate, due to ingestion of toxins or highly cooked food or a body in chronic poor health, the AGE’s attach to other molecules causing them to malfunction. Tea polyphenols aid in the prevention and elimination of AGE’s.
Tea polyphenols with caffeine assist in weight loss by increasing energy usage (thermogenesis) and fat oxidation.
In addition to cancer prevention, additional benefits of loose leaf teas, are digestion improvement as documented by Chinese over three thousand years ago. Tea antioxidants facilitate the removal of AGE’s from the body and improve the movement of food through the intestines.
Mood and Brain Disorders
Animal studies show polyphenols improve neural connections with increased cognitive abilities. Polyphenols also improve synaptic plasticity, the ability to carry electrical impulses and change connections; all of which affect mood.
Increased measures of Brain-Derived Neurotrophic Factor (BDNF). BDNF is a neurotrophin (protein) and is indispensable to the survival, growth, and differentiation of neurons. BDNF enhancing learning capacity and memory formation. Alzheimer and Parkinson's patients typically have lower than normal levels of BDNF.
However, maintaining healthy sleep time, boosts positive outlooks and cognitive abilities even with patients on drug therapies.
Psychologists recognize that routine brings one peace, pleasure and gratefulness. Historians speak of ancient books about tea ceremony and always refer to tranquility. The brewing of tea, especially for others, gives us pause to the daily stresses of life. Cooking provides the same spiritual benefits now with the added bonus of using tea as a spice.
