Those who are instructed to stay on a low-potassium diet may not be aware of just how much potassium is in their alcoholic beverages.
In this article, we’ve created a guide that covers exactly how much potassium is in wine and what the risks of heightened levels of potassium are.
We will also cover how you can enjoy your wine at the end of a long day without exceeding your recommended daily potassium intake.
Read on to find out more about:
- How potassium affects our bodies
- The potassium levels found in wine
- Which wines are lowest in potassium
- The effects of excessive potassium
- Who should be concerned about potassium intake.
Let’s get into it!
Understanding Potassium: A Quick Primer
Potassium is an essential mineral found in a variety of foods that our body uses for a range of normal functions.
Potassium helps nerves to send signals to various parts of our body, allows our muscles to contract, and helps the heart to work properly.
For adult males, the recommended daily intake of potassium should sit at around 3,400 mg, while the number is around 2,600 mg for females. Ensuring sufficient intake of potassium is important to maintain fluid balance and other bodily functions.
Foods High in Potassium
There are a variety of foods that provide high levels of potassium. While these foods provide a good supplement to their everyday diet for many people, it may be best to avoid these for those who are on low-potassium diets.
Foods high in potassium include:
- Potatoes and sweet potatoes
Wine’s Nutritional Profile: More Than Just Grapes
It is important to remember that any alcohol should be consumed in moderation and that you should never rely on wine for your nutritional needs!
However, when consumed in moderation, wine provides a source of antioxidants, minerals, and small amounts of vitamins. Antioxidants include resveratrol and flavonoids.
Meanwhile, the minerals that wine contains include both potassium and magnesium, which are essential for various bodily functions.
In addition to antioxidants and minerals, wine contains small amounts of thiamine (also known as vitamin B1).
Thiamine is essential for various bodily functions, including energy metabolism, and supports nerve function.
For many of us who drink wine, the beverage provides a way to wind down at the end of the week and can be consumed in moderation on social occasions. There is no doubt that wine has a significant role in our culture and is loved by many!
Is Wine High in Potassium?
Although wine does contain potassium, it contains relatively low levels of the essential mineral.
A glass of wine contains around 100-200 mg of potassium, so while it does contain some potassium, it is not considered a potassium-rich drink.
For perspective, the recommended daily intake of potassium is around 2,600 to 3,400mg.
Despite this, if you are on a low-potassium diet, it is important to ensure that drinking a glass of wine at the end of the day does not exceed your daily potassium intake allowance.
In general, red wine contains higher levels of potassium compared to white wine. Some sweet wines such as dessert wines may also have higher potassium levels due to the concentration of grape sugars.
Therefore, it may be best to opt for a white wine such as Sauvignon Blanc or Chardonnay or another beverage if you are concerned with the levels of potassium in your wine.
For example: a 5-ounce glass of wine contains about the same amount of potassium as a serving of 12-ounce beer.
Effects of High Potassium Intake: Why Should You Care?
The Importance of Balanced Potassium Levels
Potassium is important for numerous bodily functions. It helps neurons in our bodies send signals both to and from our brain to tell our bodies what to do. It is also involved in muscle contraction and relaxation. Other things potassium is involved in is controlling blood pressure, and heart function.
On the other hand, high levels of potassium in your blood can be dangerous and result in heart and muscle problems.
Our kidneys usually control the level of potassium in our bodies, and can keep potassium at safe limits. However, for some people, their bodies are unable to do this. Therefore, their dietary potassium levels must be carefully monitored to keep potassium in normal ranges.
Potential Risks of Excessive Potassium
For people with certain health conditions, such as kidney problems, can result in high potassium levels. The kidneys are usually responsible for controlling potassium levels, if they are not working properly this can lead to a build up of potassium. Additionally, certain medications such as diuretics, can result in an excess of potassium.
High potassium levels, also known as hyperkalemia, can cause heart irregularities, muscle weakness and a lack of energy.
Some potential risks of high potassium include:
- Heart irregularities
- Muscle weakness
- Nausea and vomiting
- Numbness and tingling
Who Should Be Cautious?
Certain groups of people should monitor their potassium intake closely and may be more at risk of high potassium levels than others.
These include people with chronic kidney disease or kidney damage.
Our kidneys help to excrete high levels of potassium, and therefore if they are not working properly, it can result in a dangerously high level of potassium if our diet exceeds what our kidneys can handle.
People who take certain medications such as diuretics or ACE inhibitors should also be cautious. These factors can result in a build-up of potassium in the blood, leading to hyperkalemia.
If you are concerned about either of these circumstances, you should always have a discussion with your doctor.
Your doctor will let you know if you should monitor your potassium intake and will give you a general guideline of your suggested intake.
Balancing Wine Consumption and Potassium Intake
If you’re someone who loves to drink wine at the end of a long week but needs to monitor your potassium intake, there are some ways to make this easier! Having dietary restrictions should not stop you from enjoying the things you love.
Keeping a food diary or using an app to monitor your daily potassium intake is a great way to ensure that the wine at the end of the day does not lead you to exceed your recommended dietary intake.
As a general rule, a glass of wine has around 100-200 mg of potassium. It is important to record this in your food journal for the day and ensure that this is within your limits.
On the other hand, if you are planning on having a couple of glasses of wine, it may be best to avoid high-potassium foods during the day.
These foods include bananas, potatoes, and spinach. Avoiding potassium-rich foods ensures that you are well below your dietary intake limits by the end of the day.
Like anything, it is important to drink in moderation and to maintain a diverse diet to help meet your dietary intake needs.
Even if you are adhering to a low-potassium diet, ensuring you have a range of food in your diet means that you are receiving adequate amounts of other vitamins and minerals your body needs.
In general, wine is not a significant source of potassium.
However, for people who need to keep track of their potassium intake (such as those with kidney problems or on certain medication), it is important to be aware that each glass of wine contains about 100-200mg.
There are practical ways to enjoy wine while on a low-potassium diet, such as keeping a food journal and avoiding high-potassium foods like bananas and spinach on the days you want to enjoy a glass.
Frequently Asked Questions
The potassium content in alcoholic beverages (including wine) is generally low and not a significant source of this mineral.
The potassium levels in a serving of wine are similar to that of a serving of beer – around 100 to 200mg – while spirits such as vodka and rum typically have less than 10 milligrams per serving.
All wines are generally low in potassium. However, red wines such as Pinot Noir or Merlot may have slightly higher potassium levels compared to white wines because they are fermented with grape skins (which contain more potassium).
Sweeter dessert wines may also contain higher levels of potassium.
Both red and white wine are generally low in potassium. However, red wine generally has a higher potassium content compared to white wine.
This is because the grape skin used to make red wine contains more potassium. You may want to opt for a white wine if you are monitoring your potassium levels.
If you are on a low-potassium diet, it is important to note down your daily potassium intake.
You should be able to drink wine if you are able to fit the wine into the limits of your daily potassium intake. It is important to consult with your doctor regardless.
