Green tea has been promoted as one of the healthiest beverages around. It is made from the same kind of leaves (camellia sinensis) as generic black tea or oolong tea. The primary difference is that while processing the leaves for green tea, the withering and fermentation procedures are avoided, which helps the leaves retain more nutrients. However, green tea comes with quite a few side effects just like ordinary tea or coffee. They are:

1. Digestive problems
Since green tea is not put through the oxidation or fermentation process, the tannins present in the leaves are not removed. Tannins, can cause nausea and constipation by producing more gastric acid. Adding a little milk to your tea might help with this problem.

2. Reduced absorption of iron
Green tea contains catechins- antioxidants, which can block the absorption of iron from food. Iron deficiency has a number of negative impacts, the most threatening one being anemia where red blood cell formation is hindered. Anemia causes fatigue because sufficient oxygen is not circulated throughout the body due to low haemoglobin levels.

3. Problems with the nervous system
Green tea contains caffeine, just like tea or coffee, though its caffeine content is lower. Excessive consumption can lead to insomnia-like tendencies, heightened anxiety, frequent urination, irregular heartbeat, muscle cramps etc.

4. Risks during pregnancy
Caffeine decreases calcium content in the body, leading to weaker bones, which is an alarming symptom in an expecting mother. Also, caffeine, catechins and tannins are individually related to increased risks of miscarriage and other negative effects. Tannins and catechins passed on to breast milk can also block absorption of nutrients like proteins and fats in an infant's system.

5. Reactions with medication
Several chemical drugs are extremely reactive to the polyphenols in green tea, especially stimulant drugs like nicotine, ephedrin and amphetamine. Green tea reduces the functioning of lithium and dipyridamole. The polyphenols may also block the healing properties of the anti-cancer drug name bortezomib. Any kind of interference with your regular medication may impact your health adversely.

6. Negative impact on patients with glaucoma
The disease impairs the optic nerve and green tea increases the pressure on the eye within minutes of drinking it because caffeine accelerates intraocular pressure. The effects take more than an hour to subside.

Green Tea: SIde effects and why you may need to avoid it

Vitamins are essential micronutrients which the body requires, though in small amounts, for optimal health. These chemicals play a crucial role in keeping our body healthy and disease free.One such vitamin is vitamin K, which is essential for optimal blood clotting process, and also has multiple other benefits. More details about the functions, benefits and sources are listed below.

Functions/Benefits:

Vitamin K is actually a group of vitamins and has K1, K2, and K3. The functions and benefits accordingly will depend on the actual chemical being referred to.
These are fat soluble vitamins and therefore absorption is better when something fatty is eaten along with it
Vitamin K1 or phyloquilline reaches the liver and is essential for blood clotting. Reduced levels of vitamin K can lead to uncontrolled bleeding, but this is very rare in adults. Newborns can have this problem, and therefore, it is common to give them a one shot of vitamin K injection.
Vitamin K2 is produced by gut bacteria and reaches blood vessel walls and bones. It prevents hardening and calcification of arteries, which is the main cause of heart disease.
It helps in improving calcium and other mineral concentration in the bones and makes the matrix strong. It can be used in osteoporosis to reverse and control bone loss. It can also be used to heal fractured bones.
It slows the growth of cancer cells and can be used to stabilise cancer. It has been shown to improve multiple forms including hepatocellular, prostate, colon, and oral cancer.
It is beneficial in controlling Alzheimer s disease and improves memory loss in ageing people
It improves insulin action and therefore prolongs onset of type 2 diabetes
It has been shown to have antioxidant properties (as most other vitamins) and also helps in reducing toxin buildup
It is good for skin health and can help control bruising and dermatitis
Sources:
Vitamin K is found naturally in many foods and the daily dose required for an adult is about 120 to 150 mcg/day. Therefore supplementation is usually not required.
Leafy green vegetables including spinach, okra, cabbage, beans broccoli, and asparagus

Fermented foods like yoghurt
Soybean in all forms including medium cooked as well and Japanese diet uses boiled, fermented soybean called natto, which contains tremendous amount of vitamin K
Nuts, such as cashews, almonds, walnuts, are a good source
Strawberries, grapes, prunes, and apples 
Seafood such as salmon and shrimp contain good amount to control heart attack and stroke.
Meat (duck, beef, chicken, and lamb)
Supplements are to be avoided, especially in pregnant and/or nursing mothers and people with a history of stroke, heart disease, heart attack and blood clotting problems.

Vitamin K - Facts You Never Knew About It!

Diabetes is a condition that affects the pancreas to the extent that it does not release the required quantity of insulin, which can lead to a high blood sugar level as the body starts to absorb excess glucose from the food that it ingests. This can be of various types and have different implications for different patients. While many experts insist that keeping a low cholesterol level and low weight is a primary requirement for the treatment of diabetes patients, there are a number of myths in this regard. Not eating fat is one such myth that we are out to prove wrong today.

So read on to find out why diabetic people need to eat fat:

Saturated Fats and Trans Fats: There are studies that demonstrate how saturated fats can actually prove to be beneficial for diabetes patients. These can be found in various sources like fish and nuts. This releases heptadecanoic acids, which can normalise the blood sugar levels as well as the insulin and triglyceride levels in the body.
Dairy Fat: The use of milk and yogurt as well as butter can actually be helpful in bringing the blood sugar levels down. It also shows up favourably on the lipoprotein markers. Butter, in particular, is known to have clarifying properties that can bring down the risk of diabetes as well. One must take care to use dairy products that are fat-free. 
Animal Fat: Having meat which releases fat and having dairy products like cheese and milk which releases healthy saturated fats are two different things. One can replace carbs and meat with these kinds of products so that there are better absorption and creation of quality animal fats which can actually help the insulin levels.
Monounsaturated and Polyunsaturated Fats: Food items like fish and nuts that carry high levels of Omega-3 fatty acids as well as monounsaturated and polyunsaturated fats can help patients suffering from diabetes by clearing the bloodstream of cholesterol and high lipid levels. This also prevents the risk of heart disease and arterial blockages. These kinds of fats are also found in flax seeds, soya products and walnuts. 
Going low on carbohydrates and avoiding sugar is usually recommended for patients suffering from diabetes. Yet, it is important to have your fill of essential fats as mentioned above with the help of dairy products, clarified better, omega three fatty acids, dry fruits, soya products and some amount of vegetable oils, as these actually have a number of benefits for these patients.

Causes and Prevention of Balance Disorders

Vitamin C is a water soluble vitamin, which is essential for various functions and it is not produced or stored by the body, so it is important that the food contains adequate amount of it. It plays a vital role in heart, eyes, skin, and prenatal health and immunity. Long-term non-availability of vitamin C can lead to various symptoms, which though are not immediately threatening, can turn dangerous in the long run.

Bruised skin: Easy bruising is one of the early symptoms of vitamin C deficiency. There could be capillaries which appear superficial and have an increased tendency to bruise and bleed. There could also be unexplained reddish purple marks on the skin in people who have low levels of vitamin C.
Bleeding gums: Another major indicator of vitamin C deficiency is swollen gums that tend to bleed easily. This again is related to their role in collagen formation and if not identified and treated in the early phases, it can lead to severe gum inflammation, periodontal disease, and even loss of teeth.
Slow wound healing: Vitamin C has an important role to play in connective tissue formation, and if there is less of vitamin C in the body, collagen formation is delayed. This can lead to prolonged and delayed healing of wounds, even simple ones like cuts and bruises. The added role of vitamin C as an immune booster also leads to reduced healing when there is vitamin C deficiency.
Nosebleeds: Frequent unexplained nosebleeds is another sign of vitamin C deficiency. Reduced amounts of vitamin C make the capillaries fragile causing them to bleed easily.
Dry skin: While weather does determine if the skin is dry or normal, vitamin C also does. The decreased levels of collagen can lead to an unhealthy skin which can turn red and can be dry and can also lead to keratosis pilaris, which is an accumulation of melanin pigments in the skin. Good amounts of vitamin D helps as a good anti-ageing agent and reduces wrinkles and retains moisture. It also has sun protective effects and antioxidant properties.
Unexplained weight gain: Vitamin C plays a vital role in fat metabolism and therefore deficiency leads to weight accumulation, especially around the waist. It helps oxidise fat and so helps in weight regulation.
Lowered immunity: Vitamin C deficiency affects the body s susceptibility to infections, making it prone to more severe and frequent infections. People catching a common cold very frequently could be suffering from vitamin C deficiency.
Emotional health: Vitamin C is also a mood regulator, so inadequate amount can lead to depression. Try eating a juicy orange and see yourself feeling better!
