Declining Fruit and Vegetable Nutrient Composition: What Is the Evidence?

“Three kinds of evidence point toward declines of some nutrients in fruits and vegetables available in the United States and the United Kingdom: 1) early studies of fertilization found inverse relationships between crop yield and mineral concentrations. The widely cited “dilution effect”; 2) three recent studies of historical food composition data found apparent median declines of 5% to 40% or more in some minerals in groups of vegetables and perhaps fruits; one study also evaluated vitamins and protein with similar results; and 3) recent side-by-side plantings of low- and high-yield cultivars of broccoli and grains found consistently negative correlations between yield and concentrations of minerals and protein, a newly recognized genetic dilution effect. Studies of historical food composition data are inherently limited, but the other methods can focus on single crops of any kind, can include any nutrient of interest, and can be carefully controlled. They can also test proposed methods to minimize or overcome the diluting effects of yield whether by environmental means or by plant breeding.”

In other words the 20% percent of the population that actually eats what they’re supposed to, now will need to eat more to offset the decline in nutrient content. Which adds calories…the solution…GreenTea HP! Concentrated antioxidants with minerals to compensate for the decrease in our food!  Josh Smith

Leukemia cells beware…green tea is here!

Last month, we talked about tea’s positive effects on two other types of cancer: breast cancer and prostate cancer. And don’t forget about the many more reasons to drink tea.

Green tea contains several antioxidants that have been shown to curb inflammation, prevent cell death, and possibly even ward off cancer.

In the current study, Dr. Stephen D. Hsu of the Medical College of Georgia in Augusta and colleagues tested the effects of green tea’s predominate antioxidant known as EGCG in laboratory mice with type 1 diabetes and Sjogren’s syndrome, which damages moisture-producing glands causing dry mouth and eyes.

They fed the mice plain water or water spiked with 0.2 percent EGCG.

EGCG, the investigators found, reduced the severity and delayed the onset of salivary gland damage associated with Sjogren’s syndrome — a condition with no known cure.

EGCG also dramatically slowed the development of type 1 diabetes in the rodents. At 16 weeks, they found, 25 percent of the mice given the green tea compound had developed diabetes, compared to 67 percent of the mice given water. At 22 weeks, 45 percent of the EGCG group had diabetes, while 78 percent of the control group did.

“Our study focused on Sjogren’s syndrome, so learning that EGCG also can prevent and delay insulin-dependent type 1 diabetes was a big surprise,” Hsu said in a statement.

Both type 1 diabetes and Sjogren’s syndrome are autoimmune diseases, which cause the body to attack itself.

Hsu and his team also found that the salivary gland cells that were under autoimmune attack were actually multiplying, but EGCG slowed this proliferation. Such rapid cell division has also been shown to occur in psoriasis.

The current study supports earlier research showing EGCG’s impact on helping prevent autoimmune disease, the researchers conclude.

Here Are The 25 Reasons Why You Should Start Drinking Green Tea Right Now:

1. Green Tea and Cancer

Green tea helps reduce the risk of cancer.
The antioxidant in green tea is 100 times more effective than vitamin C and 25 times better than vitamin E.
This helps your body at protecting cells from damage believed to be linked to cancer.

2. Green Tea and Heart Disease

Green tea helps prevent heart disease and stroke by lowering the level of cholesterol.
Even after the heart attack, it prevents cell deaths and speeds up the recovery of heart cells.

3. Green Tea and Anti-Aging

Green tea contains antioxidant known as polyphenols which fight against free radicals.
What this means it helps you fight against aging and promotes longevity.

4. Green Tea and Weight Loss

Green tea helps with your body weight loss. Green tea burns fat and boosts your metabolism rate naturally.
It can help you burn up to 70 calories in just one day.
That translates to 7 pounds in one year.

5. Green Tea and Skin

Antioxidant in green tea protects the skin from the harmful effects of free radicals, which cause wrinkling and skin aging.
Green tea also helps fight against skin cancer.

6. Green Tea and Arthritis

Green tea can help prevent and reduce the risk of rheumatoid arthritis.
Green tea has benefit for your health as it protects the cartilage by blocking the enzyme that destroys cartilage.

7. Green Tea and Bones

The very key to this is high fluoride content found in green tea.
It helps keep your bones strong.
If you drink green tea every day, this will help you preserve your bone density.

8. Green Tea and Cholesterol

Green tea can help lower cholesterol level.
It also improves the ratio of good cholesterol to bad cholesterol, by reducing bad cholesterol level.

9. Green Tea and Obesity

Green tea prevents obesity by stopping the movement of glucose in fat cells.
If you are on a healthy diet, exercise regularly and drink green tea, it is unlikely you’ll be obese.

10. Green Tea and Diabetes

Green tea improves lipid and glucose metabolisms, prevents sharp increases in blood sugar level, and balances your metabolism rate.

11. Green Tea and Alzheimer’s

Green tea helps boost your memory.
And although there’s no cure for Alzheimer’s, it helps slow the process of reduced acetylcholine in the brain, which leads to Alzheimer’s.

12. Green Tea and Parkinson’s

Antioxidants in green tea helps prevent against cell damage in the brain, which could cause Parkinson’s. People drinking green tea also are less likely to progress with Parkinson’s.

13. Green Tea and Liver Disease

Green tea helps prevent transplant failure in people with liver failure. Researches showed that green tea destroys harmful free radicals in fatty livers.

14. Green Tea and High Blood Pressure

Green tea helps prevent high blood pressure.
Drinking green tea helps keep your blood pressure down by repressing angiotensin, which leads to high blood pressure.

15. Green Tea and Food Poisoning

Catechin found in green tea can kill bacteria which causes food poisoning and kills the toxins produced by those bacteria.

16. Green Tea and Blood Sugar

Blood sugar tends to increase with age, but polyphenols and polysaccharides in green tea help lower your blood sugar level.

17. Green Tea and Immunity

Polyphenols and flavenoids found in green tea help boost your immune system, making your health stronger in fighting against infections.

18. Green Tea and Cold and Flu

Green tea prevents you from getting a cold or flu.
Vitamin C in green tea helps you treat the flu and the common cold.

19. Green Tea and Asthma

Theophylline in green tea relaxes the muscles which support the bronchial tubes, reducing the severity of asthma.

20. Green Tea and Ear Infection

Green tea helps with ear infection problem.
For natural ear cleaning, soak a cotton ball in green tea and clean the infected ear.

21. Green Tea and Herpes

Green tea increases the effectiveness of topical interferon treatment of herpes.
First green tea compress is applied, and then let the skin dry before the interferon treatment.

22. Green Tea and Tooth Decay

Green tea destroys bacteria and viruses that cause many dental diseases.
It also slows the growth of bacteria which leads to bad breath.

23. Green Tea and Stress

L-theanine, which is a kind of amino acids in green tea, can help relieve stress and anxiety.

24. Green Tea and Allergies

EGCG found in green tea relieves allergies.
So, if you have allergies, you should really consider drinking green tea.

25. Green Tea and HIV

Scientists in Japan have found that EGCG (Epigallocatechin Gallate) in green tea can stop HIV from binding to healthy immune cells.
What this means is that green tea can help stop the HIV virus from spreading.

Antioxidant Properties

Most of us have heard of the positive effects red wine can have on a fatty diet and its healthful benefits on heart disease. High amounts of catechins polyphenols, particularly EGCG, are present in green tea. And EGCG has twice as much resveratrol as red wine, making it a powerful weapon towards lowering cholesterol, inhibiting blood clots and negating the effects of a fatty diet.

EGCG is also used to treat diabetes and is reported to have glucose-lowering effects. In addition glucose can cause a person to feel hunger and by controlling insulin levels, you control appetite. Try drinking a mug of green tea at the first hunger pain and you are well on your way to managing your appetite.

Thermogenesis

Thermogenesis literally means heat generation. Green tea increases thermogenesis in the body, becoming a potent appetite suppressant and increasing fat oxidation, helping the body to use fat as an energy source. This means the body is preferentially burning fat over protein.

Green tea also raises the body’s metabolism, increasing the rate at which calories are burned. In a recent study, the combination of green tea and caffeine burned more calories than those given a placebo.

Add to its thermogenesis benefits, green tea also has energy-boosting properties, which makes it a perfect breakfast tea or mid-afternoon pick me up.

Other Healthful Benefits

There are many other conditions in which green tea is reputed to be helpful:

* Killing cancer cells, while leaving healthy cells untouched

* Treating Rheumatoid arthritis

* Lowering LDL cholesterol

* Preventing thrombosis which causes heart attacks and strokes

* Addressing cardiovascular disease by inhibiting abnormal formation of blood clots

* Preventing infection

* Improving impaired immune function

* Stopping certain neurodegenerative diseases (such as Parkinson’s and Alzheimer’s)

* Treating multiple sclerosis

* Preventing tooth decay by killing the bacteria that causes dental plaque

When you compare the heath benefits of green tea with the harmful effects of regular and diet soda, coffee and other damaging drinks, it is easy to see why green tea has a long and successful history of benefiting the drinker.

Adding Green Tea to Your Diet

Green tea has become so popular that it can be found in mainstream grocery stores as well as gas stations and convenience stores. There are many flavors and varieties of green teas so you will be sure to find a combination of flavors you’ll enjoy.

Consider also adding green tea water to some cooked foods. Adding tea to a pot of boiling pasta will affect the flavor in a fresh new way. Toss that same pasta with pine nuts, pesto and a dash of olive oil and you have a healthful dish with many antioxidant properties. Challenge yourself to find new and exciting ways to add green tea to your diet.
