The harm of natural juices is not just an exaggeration, it is true that juice is very useful for health, however, it does not have to be a substitute for any other food source.
Juice is a liquid that is naturally present within the tissues of a vegetable or fruit, and these liquids are extracted by squeezing, and no heat is needed in the process.
Containing juices on essential nutrients good for health such as minerals and vitamins. For example, orange juice is rich in vitamin C antioxidants, while cranberry juice helps protect against urinary tract infections , but there are some harm of natural juices:
1. High blood sugar
Raw fruit juice has a high glycemic index, which means that decisiveness makes carbohydrates quickly, because of the absence of fiber, the body absorbs sugar faster than it does when eating whole vegetables or fruits. Which leads to the rapid escalation of blood glucose and the appearance of complications especially in patients with diabetes and other disorders like blood.
2. Intestinal tightness
The freshly squeezed juice from a particular fruit such as sweet cherries, pears contains a high concentration of sorbitol, a form of indigestible sugar, found naturally in the fruit according to some specialists, so the body can not naturally digest this sugar, but the vital bacteria present in the digestive system do so but the result is the formation of gases that cause bloating and discomfort, and sometimes sorbitol
3. Exposure to diseases
Drinking juices from fruit or vegetables that are not well washed or not properly preserved may expose a person to bacterial diseases, according to a study of the University of Valencia published in 2011 in Food Control Journal, which showed that 43% of samples of fresh orange juice contain higher levels of Enterobacteria (a type of germ) than allowed in Spanish law:
0.5% and 1% of these samples include salmonella cluster gold, respectively.
While the immune system can deal with these bacteria most of the time, there are some cases of weakened immunity such as children and the elderly who are at risk of becoming ill from eating these contaminated juices.
4. Weight gain
Some fruit juices, such as oranges and pineapples, have a high sugar content, combined with the absence of dietary fiber, which causes a rise in calories, which leads to weight gain.
According to a study by researchers at Deakin University, Australian children who drank fruit juices had a greater chance of becoming obese or overweight.
Replacing some food with juice results in lower intake values than other micronutrients, such as protein.
The Harvard School of Public Health has advised that we eat whole fruit instead of juice for weight loss, as we contain more fiber.
