How sugar effects our kidneys

by Hannah Singleton

There is no doubt that the Western World consumes an excessive amount of sugar. Sugar can come in a variety of forms with the main types being glucose, fructose or a combination of the two, i.e. sucrose*. These sugars are all metabolised differently in the body. When trying to decide  which sugars to avoid, the main points of consideration are:

  • Processing
  • Nutrients
  • Type of sugar
  • Glycemic index
  • Quantity of use

Put simply: If the sugar comes in it’s natural form, that is fruit and vegetables and is consumed as a whole food, it is unlikely to be a problem for most people. The nutrients, fibre and natural sugars will be utilised by the body and satiety will prevent overconsumption. However, if the sugars are added to foods with few nutrients and little to no fibre, blood sugar will spike, the liver will struggle to metabolise the fructose portion, satiety will not occur through disruption of hormones such as leptin and the kidneys will be put under stress. All of these factors will encourage over eating whilst simultaneously leaving the body and brain undernourished. 

In honour of World Kidney Day, March 14, we have uncovered how high sugar diets can harm our kidneys. We have also shared a detox juice recipe to help soothe our often over-worked kidneys. They can always use a little extra love!

The impact of sugar on our kidneys

Our kidneys are critical detoxification organs. They assist with a number of fundamental bodily processes that include removing waste, balancing body fluids and creating urine.

There are a number of lifestyle and dietary factors that impact our kidneys, from over consumption of salt and eating too many processed foods, to dehydration and binge drinking. What is becoming increasingly recognised though is how high sugar diets can negatively impact our kidneys. It is well established that excess sugar consumption can lead to a myriad of health conditions, with a key side effect being obesity. Obesity is commonly associated with high blood pressure and diabetes which are two of the main contributing factors in kidney disease.

How to avoid sugar?

What many people are surprised to learn is just how much added sugar there is in a  large majority of packaged foods. We all know that lollies and chocolate are a no-go if you’re trying to reduce your sugar intake, but did you know that there can be just as much sugar in so called ‘health’ foods? Be wary of sugar lurking in your bread, salad dressings, yoghurt, muesli, juice, dairy free milks, sushi… the list could go on for days. The best way to limit sugar consumption is to prepare your own food so you know exactly what is going in. Alternatively, it is a good habit to read food labels to check for any harmful additives.

Another key culprit for overconsumption of sugar in western societies is without doubt, soft drinks. Sugar is highly addictive which makes it hard to break the cycle if soft drinks are a part of your every day ritual. We can certainly help you here! Nexba beverages are 100% natural and 100% sugar free. Our team of experts have spent years in innovation matching the natural sugar curve to bring you sugar free beverages that don’t compromise on taste. This is done using a mixture of natural ingredients including Stevia, erythritol, natural flavours and fruit extract.

Soothe your kidneys with our detoxifying probiotic juice

If you’re looking for a way to soothe and support your kidneys, there are a number of nourishing foods that can do just that.

First and foremost, it is very important for kidney health that you are drinking enough water. Aim for at least 8 glasses per day, or more throughout the warmer months, during exercise and/or when drinking dehydrating substances such as tea and coffee.

Here we’ve shared our detoxifying probiotic beetroot, lemon and ginger juice recipe to help cleanse the body.


Servings 2

2 green apples, cored

  2. Transfer to jug and mix through Probiotix Water.
  3. Serve on ice and garnish with mint.

 Why these ingredients?

Apple: Apples are high in fibre which can prevent constipation. They are also high in anti-inflammatory compounds and are a good source of pectin which helps to lower cholesterol. 

Lemon: Lemon helps to prevent kidney stones and are known to assist with detoxification.

Beetroot: Some studies suggest that beetroot (both in the form of whole food and supplementation) can be used to prevent kidney failure. NOTE: If you are susceptible to kidney stones, over consumption of beetroot (including beet greens) can be harmful. Consult your health care practitioner if you have experienced kidney stones.

Ginger: Ginger is a powerful anti-inflammatory and antioxidant spice that assists kidneys to function optimally.

*The 3 main types of sugar:

  1. Glucose: Metabolised in all cells and converted to energy. Glucose requires insulin for transport into cells.
  2. Fructose: Metabolised in the liver. Does not require insulin for metabolisation.
  3. Sucrose: 50% glucose + 50% fructose
