Correlation between consumption of fruits, vegetables, and fruit juices with diabetes

One of the main causes of various chronic diseases, today is an unhealthy diet. Today on the menus in developed countries dominated meat and meat products, pastry, sweetened and carbonated drinks, artificial sweeteners, genetically modified foods and foods enriched with various additives. Today’s fast lifestyle also contributes to unhealthy diet, which is based on quick prepared meals. People increasingly forget how people used to fed, when the diet was based largely on vegetables and fruits. Many scientific studies carried out to prove the connection between the diet and the occurrence of various chronic diseases, that a large number of the population suffering today, like obesity, cardiovascular diseases, metabolic changes, diabetes and cancer. Of course, proper and healthy diet is not the only cause of chronic diseases, but it is one of the most important factors for their development and emergence.

The emergence of type 2 diabetes, has been increasing rapidly and is associated with the increasing emergence of obesity. It is estimated that in 2000. 171 million people in the world suffered from type 2 diabetes, according to predictions the number of patients will grow by 2030 to 366 million. Today, through more scientific studies proved that eating fruits and vegetables helps reduce the occurrence and mortality from obesity, high blood pressure, and cardiovascular disease. The link between the consumption of fruits and vegetables and diabetes is not much studied.

A small number of scientific studies about the connection between the consumption of fruits, vegetables and fruit juices with diabetes, and in general the impact of fruit juices which may contain higher amounts of sugar, were the reason that a group of scientists investigate their connection. In 2009. was published scientific study on the connection between the consumption of fruits, vegetables, and fruit juices with type 2 diabetes in women (Intake of Fruit, Vegetables, and Fruit Juices and Risk of Diabetes and Women). They studied the connection between entry of all kinds of fruits and vegetables, certain kind of fruits and vegetables, and fruit juices and their role in the development of diabetes in women. The study included 71,346 women aged 38-63 years, who have not suffered from heart disease, diabetes or cancer. The survey was conducted in the period 1984-2002. During 18 years of research, every four years, were collected information on diet, with the semiquantitative examination method. During the study are documented 4529 cases of diabetes in participants.

The results showed that the overall fruit and vegetable intake was not associated with the occurrence of diabetes, intake of fruit juices was positively associated with the occurrence of diabetes, and the entire intake of fruits and green vegetables is negatively associated with the occurrence of diabetes. The positive correlation between diabetes and fruit juices probably refers to the lack of fiber and other phytochemicals, large levels of sugar, liquid form and the absence of other components that we consume by eating whole fruit. Frequent consumption of fruit juice can contribute to higher glycemic load which is directly related to the emergence of type 2 diabetes. While consumption of whole fruits and green vegetables, which is low in energy, has a low glycemic load, and is rich in fiber and micronutrients, especially magnesium, have adversely affected on the appearance of diabetes.

Although more research is needed on the relationship between fruit and vegetables and fruit juices with diabetes, it is emphasized that should be careful when replacing some beverages with fruit juices, as a healthier option, and with the recommendation that 100% concentrations of fruit juice can be considered as a substitute for a meal of fruit. Also, it is emphasized that the replacement of refined grains and potatoes with fruit and vegetables in the diet is very important and contributes to a reduced risk of diabetes, as well as the overall consumption of whole fruits and vegetables.
