Juicing is gaining in popularity worldwide, but plenty of myths are abound about the benefits and health concerns of drinking fresh juice.
Plenty of myths are abound about the health benefits and concerns of drinking fresh juice. SingHealth Polyclinics (SHP) help to debunk the myths and presents the facts.
Fact: Weight loss occurs if you consume fewer calories than you burn. Hence, if you consume 1200-1400 calories of juice each day as part of a juice cleanse, and your recommended calorie intake is 1700 calories, you are likely to lose weight because of the calorie deficit. But a juice cleanse is akin to a crash diet and any weight loss it causes will be in the short term only. Once you resume your normal diet, you will probably put on any kilos you have lost.
Additionally, a juice diet will be nutritionally unbalanced, since you will not be getting the recommended quantities of fibre, protein and other nutrients. This is likely to cause a loss of muscle mass and food cravings, as well as other health problems such as high blood sugar. Hence, it’s best to consume the recommended one serving of juice as part of a balanced diet, and cut down your overall calorie intake to lose weight healthily.
Fact: There isn’t any scientific evidence to support this claim. Your body organs such as the liver and kidneys are responsible for detoxifying and cleansing your body. These organs help remove toxins from the body in a natural process. During a juice cleanse, a person is likely to burn their glycogen stores for energy, which can cause the body to lose water. A cleanse can also lead to side effects such as a lack of energy, headaches, irritability, low blood sugar and constipation.
Fact: There isn’t any scientific evidence to support this claim. Your digestive system is designed to extract nutrients from different foods, even those which are rich in fibre. In fact, fibre has an important function in the digestive and excretory systems, and is essential for digestive and gut health.
Fact: It’s likely that you are getting more calories and sugar when you drink a smoothie as store-bought smoothies often contain added sugar, honey, fresh milk, yogurt and other ingredients to make them more palatable. With higher calorie consumption, it may lead to weight gain. Hence eating whole fruits and vegetables is a healthier option than drinking a smoothie.
Fact: Excess consumption of spinach and kale will interact with anti-blood clotting medication. However, these vegetables are safe to consume for patients on blood-clotting medication, provided they maintain a consistent intake of Vitamin K-rich foods, such as spinach and kale in their daily diet.
7 Ways to juice healthier
It’s important to wash any fruits and vegetables you use very carefully to remove all dirt and pesticides.
Always use clean appliances and juicer for juicing, and wash them thoroughly immediately after use.
Combine your least favourite vegetable with your favourite fruit for a healthy juice blend and reduce the amount of sugar in the juice.
Use a variety of fruits and vegetables for juicing. Avoid having the same juice every day.
Add some of the pulp back into the juice.
Make your juice healthier by adding chia seeds or ground flaxseeds.
Only juice what you want to consume immediately. Juice loses its nutritional value and can develop bacteria if it is left standing.
