- When combined with milk, tea can offer an array of vitamins and minerals including calcium, vitamin B6, Riboflavin B2, Thiamin B1, manganese for bone growth and repair, and potassium, important for neuron and brain function.
- Tea reduced total cholesterol levels, although HDL cholesterol (or good cholesterol) levels, depleted by high fat diets recovered only with the consumption of HGN (high grown new) tea.Tea contains catechins, a type of antioxidant which has been found to reduce people's risk of heart disease, stroke and diabetes. Catechins can also be found in cocoa and dark chocolate.
- Tea drinking mainly influences the absorption of non-haem iron as haem iron is relatively unaffected by tea.

- Tea did not have any effect on triglyceride levels.
- One or two cups of tea have the same 'radical scavenging capacity' as five portions of fruit and vegetables.

The poly phenols present in tea act in many beneficial ways to human health. A cup of tea contains about 1000 ppm (parts per million) poly phenols. The catechins available in tea poly phenols has the capacity of suppressing the excessive rise of cholesterol , inhibiting hypertension , reducing glucose levels in the blood , preventing cardio-vascular diseases , lowering high blood pressure and keeping intestines in good order.
