Green Tea vs Coffee (III)

Green tea is associated with a reduced risk of stroke, diabetes and depression. This is because it improves insulin sensitivity and reduces blood sugar levels.  Thus it may lower the risk of type 2 diabetes. 

Also, coffee drinkers have a much lower risk of type 2 diabetes. Those who drink the most coffee have up to a 29% lower risk of developing type 2 diabetes. 

Regularly drinking 4 cups of coffee per day may also reduce the risk of developing gout by 40% in men and 57% in women while consuming 3 cups of coffee a day for as few as 3 weeks may increase the amount and activity of beneficial gut bacteria.

Boost longevity

Given that some compounds in green tea may help protect against cancer and heart disease, it could help you live longer. In one study, it was found that those who drank the most green tea — 5 or more cups per day — were significantly less likely to die during the study period.  

The same for coffee drinker.  

Coffee drinkers have a lower risk of death. Drinking coffee was associated with a 20% reduced risk of death in men and a 26% decreased risk of death in women. It may decrease the risk of premature death by as much as 30%, especially for women and people with diabetes.

Contain Essential Nutrients

A single cup of coffee contains: 

• Riboflavin (vitamin B2): 11% of the Reference Daily Intake (RDI).
  Riboflavin is crucial for breaking down food components, absorbing other nutrients and maintaining tissues. It is important for body growth. It helps in red blood cell production. It also aids in the release of energy from proteins.
  
  
• Pantothenic acid (vitamin B5): 6% of the RDI.
  Pantothenic acid is necessary for making blood cells and it helps convert the food into energy by breaking down fats and carbohydrates. It also promotes healthy skin, hair, eyes and liver.

• Manganese and potassium: 3% of the RDI.
  Manganese and potassium are trace minerals. It is vital for our body.

  Manganese contributes to many bodily functions, including the metabolism of amino acids, cholesterol, glucose and carbohydrates. It also plays a role in bone formation, blood clotting and reducing inflammation. For people with diabetes, manganese may help lower blood sugar levels and help the pancreas create insulin.
  
  Manganese also helps form an antioxidant enzyme called superoxide dismutase (SOD) which breaks down a dangerous free radical, called superoxide, into smaller components that are not harmful. 
  
  

  Potassium regulates fluid balance, muscle contractions and nerve signals. A high-potassium diet may help reduce blood pressure and water retention, protect against stroke and help prevent osteoporosis and kidney stones.
  
  
• Magnesium and niacin (vitamin B3): 2% of the RDI. 
  Low levels of magnesium can significantly affect the sleep and cause you to feel fatigued while niacin keeps skin healthy, helps with digestion and can lower cholesterol levels while magnesium benefits the body by:
• relieving muscle tension
• improving sleep quality
• repairing muscle tissue
• strengthening bones
• helping to synthesize proteins
• replenishing the skin

Green tea contains two substances related to caffeine: theobromine and theophylline. Both have several physiological effects on the body. 

Theophylline relaxes smooth muscles in the airway, making breathing easier while also stimulating both the rate and force of heart contractions.  

Theobromine can also stimulate the heart, but it does have a mild diuretic effect and improves blood flow around the body, leading to a net reduction in blood pressure.
