Health And Green Leafy Vegetables

 

The studies below found some significant facts regarding health effects of certain food.  This is an attempt by us to interpret the findings so that it could be implemented in everyday health practices.  It has to be understood that good eating habits are necessary for optimal health and that means that a variety of good foods have to be consumed every day.  We do believe that some food has medicinal value and could be used to help in the prevention and support of treatment in certain illnesses.  However, if it is not part of a good nutritious diet, it might lose its value.    Although we do believe in the power of natural food, we absolutely do not claim to cure any disease through the consumption of specific food.

Soo Yeon Kim, Sun Yoon, Soo Mi Kwon, Kye Sook Park, Yang Cha Lee-Kim. Kale juice improves coronary artery disease risk factors in hypercholesterolemia men. Biomed Environ Sci. 2008 Apr;21(2):91-7. 
In this study 32 men with high cholesterol consumed 150 ml of kale juice per day for 12 weeks.  After this time, there was an increase in HDL, the good cholesterol while there was a decrease in LDL, the bad cholesterol.  Apart from this, there was also a significant increase in enzymes which supports immunity (glutathione peroxidase and selenium).  These results were not as great among smokers than non- smokers.

This study looked at 17 studies including 9447 case studies to show the effect of the consumption of fruit and vegetables on the development of bladder cancer.  It was shown that the higher the consumption of green leafy vegetables, the smaller
the risk was in the development of the disease.  Consequently it was concluded that green leafy vegetables might even help prevent bladder cancer. 
 
 
3.  Type II diabetes
Ping-Yu Wang, Jun-Chao Fang, Zong-Hua Gao, Can Zhang, Shu-Yang Xie. Higher intake of fruits, vegetables or their fiber reduces the risk of type 2 diabetes: A metaanalysis. J Diabetes Investig. 2016 Jan ;7(1):56-69. Epub 2015 Jun 22
Twenty three articles were used to carry out a meta-analysis between the intake of fruits, vegetables and fiber and the risk of developing type 2 diabetes.   
It was found that a higher intake of fruit, especially berries, and green leafy vegetables, yellow vegetables, cruciferous vegetables or their fiber is associated with a lower risk of development of type 2 diabetes.

Jae H Kang, Alberto Ascherio, Francine Grodstein. Fruit and vegetable consumption and cognitive decline in aging women. Ann Neurol. 2005 May ;57(5):713-20. 
In this prospective study, done from 1976 to 2001, women were studied for fruit and vegetable intake and their decline of cognitive function.  It was found that total vegetable intake was associated with less decline.  Spicifically green  leafy vegetables and crucifirous vegetables were associated with higher cognitive function.  As consumption of these vegetables were increased, there was less decline in function.

Rose, P, Ong, CN, et al. Protective Effects of Asian Green Vegetables against Oxidant Induced Cytotoxicity. World J Gastroenterol 11(48)7607-14. PMC4727240
This article showed that green leaf vegetables are potential sources of antioxidants and phase II detoxification enzyme inducers. It is likely that consumption of such vegetables is a major source of beneficial phytochemical factors that may protect against colonic damage.

This is a study which claims that the consumption of fruits and vegetables by young, healthy individuals is related to an array of states of well-being favorable to human flourishing.  This was not found to be the case when unhealthy food (junk and fast food) was consumed.  A point of interest was that good nutrition only had a short term effect, in other words, one good meal did not guarantee unlimited time of well-being.  I suspect however that the longer the period of good food consumption is, the longer the effect will last.

As a high school teacher of more than 20 years I have developed an appreciation for teenagers and young adults.  The possibilities in life were unlimited for most of them – in their minds the world was there to conquer and serve them.  And they had the energy to help conquer the world, well at least some.  We are well aware of a growing concern that many young people who are disheartened about this world are resorting to drugs and alcohol in order to subdue these thoughts. 

Although I do acknowledge the complexity of this problem, I cannot help recognizing the role that good nutrition could play in our attempt to help young people of today.  It seems as if nutritious food will not only help youth to find purpose in life but also provide them the energy to realize their full potential.  Parents, please educate yourself about healthy food and nutrition for children.  As well, school boards, please make the effort to help the young people to make tasty, healthy choices when it comes to food options provided by school cafeterias.
