Not all green foods are healthy

Vegetables and fruits are generally considered an important part of a healthy diet.  Health experts also recommend including them in a balanced meal. However not everything that is green is automatically good for everyone. Some raw undercooked artificial or  rich green foods may cause health problems in  certain people.

People with weak immune systems may be more sensitive to some foods and could experience allergies food reactions or other health problems. Green potatoes some green seafood products and foods with artificial green coloring are examples that may require extra care. Some people can also develop an allergy or intolerance to certain green foods.

For example spinach may cause skin rashes or other allergic symptoms in sensitive individuals. In rare and serious cases a food allergy can lead to a dangerous reaction called anaphylaxis.

Anyone who notices allergy symptoms after eating a particular food should seek medical advice.

People with IBS (Irritable Bowel Syndrome) may also need to be careful with certain green vegetables.  Foods such as cabbage broccoli and Brussels sprouts can cause gas bloating stomach discomfort and pain in some people.

People with kidney problems should also pay attention to their food choices. Spinach and Swiss chard contain high amounts of potassium.

Eating too much of these foods may be risky for people with advanced kidney disease because their kidneys may have difficulty removing extra potassium from the body.

This can lead to an unhealthy electrolyte balance. Eating too much of any food can cause problems and green foods are no exception. Large amounts of raw vegetables may cause bloating, constipation stomach pain or digestive discomfort in some people. In certain cases excessive intake of particular foods may also increase the risk of kidney stones electrolyte problems low blood sugar or allergic reactions.

Some green fruits and vegetables may also cause digestive problems when eaten raw.  For example raw bananas and papaya may cause gas or stomach discomfort in some people.

People who take warfarin a blood thinning medicine also known by the brand name Coumadin should talk to their doctor about eating large amounts of green leafy vegetables.

These vegetables are often high in vitamin K, which can affect how warfarin works. The important thing is usually to keep vitamin K intake consistent rather than suddenly changing the amount.

Spinach, Swiss chard and beetroot are also high in oxalates.  For some people who are prone to kidney stones, eating large amounts of these foods may increase the chance of developing stones again.

Raw or lightly cooked green vegetables can provide many nutrients but they can sometimes be difficult to digest.  Vegetables such as cabbage broccoli and Brussels sprouts contain fiber that may cause digestive discomfort in some people especially when eaten in large amounts.

Green potatoes are another important exception. When a potato turns green it may contain higher levels of a natural chemical called solanine.  Eating a large amount of solanine can cause nausea, vomiting, and in severe cases nervous system problems.

Green potatoes should therefore be handled with care. Green tea is also not completely harmless in every situation.

Poor quality green tea may contain unwanted impurities or low quality ingredients. Drinking very strong or very hot green tea may cause stomach discomfort in some people. Green tea also contains caffeine and too much caffeine can lead to nervousness shaking sleep problems or other side effects.

Artificially green foods are not necessarily healthy either. Green colored candies sweet drinks and other processed foods may contain large amounts of sugar and provide little nutritional value.  Eating these foods regularly can contribute to tooth damage high blood sugar and other health problems.

The main point is that green color alone does not make a food healthy.  The type of food the amount eaten how it is prepared and a person’s health condition all matter. People with food allergies, IBS, kidney problems or those taking certain medicines should be especially careful and seek medical advice when needed.
