As with lots of foods, everyone seems to have a different opinion about whether or not peanut butter is healthy and why.
One thing that everyone agrees on though is that some peanut butters are healthier than others, in particular those with the lowest sugar, vegetable oil and salt content.
Is Peanut Butter Healthy?
Peanut butter can be healthy in moderate amounts. Here’s an overview of its health benefits and potential negative effects.
Peanuts can help to keep your heart healthy and can possibly even stave off chronic diseases and possibly even reduce the risk of mortality in those who consume an average of 10 grams per day (source).
Peanuts are good way to meet lots of your dietary requirements, as they contain:
- Antioxidants (mainly found in the skins)
- Monounsaturated and polyunsaturated fats
This doesn’t mean you should grab a packet of salted peanuts or that jar of peanut butter and polish it off, as peanuts are healthiest when consumed in their natural state.
Many peanut butters add in vegetable fats and extra salt, which can take away from the healthy elements of the nuts, but more recently, more health-conscious brands have been competing to create the healthiest peanut butter on the market.
When you buy a regular jar of peanut butter, there are a few ingredients to look out for which might make your choice of peanut butter less healthy than you might think.
Frequent additions to peanut butter can include:
- Vegetable oil
- Palm oil (which also often produced in an unsustainable way)
Potentially Harmful Effects
Peanut butter is generally considered to be healthy in moderate amounts, but there are some potentially harmful effects of eating too much.
- Too much omega 6 – Most people in the UK consume two much omega 6 and not enough omega 3.
An omega 6 to omega 3 ratio of 4:1 is recommended, but for most people in the Western world this ratio is at least 12:1.
Peanuts contain virtually no omega 3, and have about 5,000 times as much omega 6 as omega 3, so they’re not good for your overall omega 3 to 6 balance.
If you eat a lot of peanut butter, it might be a good idea to also take an omega 3 supplement, or up your intake of omega 3-rich fish such as sardines and mackerel.
- Mould and fungus growth – Peanuts are grown on the ground where they can get moist and acquire mould and fungus. This is linked to allergies, and some mould found in peanut butter can even be a carcinogen.
- Oxalates – Peanut butter is high in oxalates, which can cause kidney stones.
How to Choose a Healthy Peanut Butter
Choosing a healthy peanut butter is quite straightforward. Look for the following things:
- High peanut content –The healthiest peanut butters are made from 100% peanuts, with no added preservatives, salt or sugar.
- No added sugar – Peanuts naturally contain small amounts of sugar (about 3 g per 100 g). Added sugar increases the calorie content.
- Vegetable oil free
- Low in salt
List of the Healthiest Peanut Butter Brands
Here’s a list of the healthiest peanut butter brands we could find on the market in the UK in 2019. We looked for brands that met our criteria of having high peanut content, no added sugar or vegetable oil, and being low in salt.
Some people find these peanut butters to be dry or bland in taste. They can take some getting used to if you’re accustomed to sweet peanut butter packed with added sugar.
Since these peanut butters are all very similar, it’s hard to say which is the #1 healthiest. That’s why we have listed them in alphabetical order rather than in a ranking.

- Not all that sweet
If you’re used to a sweeter taste of peanut butter, this one may take a little getting used to, but this lets you know it’s healthier!

Some people have complained that the plastic container shattered as they took the lid off.

Meridian Natural Crunchy Peanut Butter
Price Range: ££
Ingredients: Roasted peanuts – whole skin on
Meridian Natural Crunchy Peanut Butter is one of the few manufacturers who produce their butter leaving the peanut skin on.

The overall look of the peanut butter is slightly darker than other varieties due to the skin on process.
- Made from 100% skin-on peanuts
- Skin left on during roasting – adds depth to flavour
- Wholesome taste
- Relatively well priced (better price when bought in bulk)
- Can separate really easily
- Can be a little difficult to stir

This PB gets some really good customer reviews and is one of the most popular on this list.
Out of all of the butters in this list, Meridian might be the best peanut butter for weight loss as the natural flavourings are great for satiating food cravings!

Calorie Content Compared
According to MyFitnessPal, 100 g of peanuts contain 567 calories.
It’s interesting that different peanut butters with a 100% peanut content list quite different figures for their calorie content.
This could be due to:
- Skins on vs. off – Peanut butters made with the skins could have a different calorie content.
- Roasting method – Oil roasting results in a higher calorie content than dry roasting.
- Variety of peanut – Some varieties of peanuts have a lower calorie content. Virginia peanuts have slightly less calories than Valencia peanuts.

Whole Earth Crunchy Peanut Butter

Peanut Butter FAQs
What is the healthiest peanut butter to eat?

What’s the lowest calorie peanut butter in the UK?
According to our research, the lowest calorie peanut butter in the UK is Protein Works’ Peanut Butter, which contains 564 calories per hundred grams.
Is peanut butter good for weight loss?
Peanut butter could help with weight loss by preventing cravings for less healthy foods.
Peanut butter is very calorie-dense and is often consumed by bodybuilders trying to gain weight. However, eating moderate amounts of it can be quite helpful if you’re looking to lose weight, as long as you’re eating it as a substitute for even higher calorie foods.
This article on VeryWellFit.com has some links to different research studies that found that snacking on peanut butter helped people curb their appetite and feel full, preventing them from snacking on less healthy foods.
Peanut butter, of course, tastes really great (if you like it) so almost acts as a treat which can help people to stick to a diet more effectively.
Although peanuts are best for you when they are consumed in their natural state, there are still benefits to eating peanut butter when trying to manage your weight.
Peanut butter is sometimes a more convenient way to consume your daily intake of nuts and many like to combine it into their snack routine; sometimes eaten between two slices of apple.
Peanuts are filled with fatty acids which sounds bad, but these are monounsaturated fats which are actually considered healthy fats when consumed as part of a balanced diet.
Making Your Own Peanut Butter
One way to ensure you’re eating something really healthy is to make it yourself.
The simplest peanut butter recipe involves food processing roasted peanuts (which you can do yourself to ensure no extra salt is added) until they form a smooth spread.
During the blending process, you could add a little salt or even honey to help get the spreadable consistency of a smooth butter. You could blend it for less time to leave you with a crunchier texture.
If you want to get a smooth texture you could experiment with adding vegetable or olive oil, instead of palm oil.
Here’s a short YouTube video that shows how to make your own peanut butter:
If you’re looking for a low calorie peanut butter, the lowest calorie option we could find was The Protein Works Peanut Butter at 564 kcal per 100 g.
In terms of overall health effects, there isn’t much difference between the peanut butters listed here. Remember to eat peanut butter in moderation and as part of a healthy and balanced diet.
