Fresh juices have long been categorized as health foods and it's common for people on weight-loss diets or detox plans to consume them, without worrying about any adverse consequences. However, the bad news is that without the fibre part, fruit or vegetable juices can do more harm than good as the natural sugar in them can instantly raise blood glucose levels. Consuming too much sugar is linked to increased risk of heart disease, stroke, type 2 diabetes, dental cavities and also some types of cancer.
Fruit or vegetable juices must be consumed strictly in moderation and if a latest study published in journal Nutrients is to be believed, juice cleanses or a short term diet of only vegetable or fruit juice, which is aimed at improving digestion, or weight loss, even if followed for just three days, can adversely affect gut and oral bacteria, and may lead to long-term health consequences.
