Is Peanut Butter Healthy? Here’s All the Proof You Need

So you want to know: is peanut butter healthy? If you're a health-conscious consumer, you may be unsure if this creamy spread is actually nutritious or if it's all hype. Well, we have all the proof you need here. Find out why peanut butter is such a versatile food that provides an array of health benefits. From being packed with vitamins and minerals, polyphenols and protein, to its richness in healthy fats, there’s no doubt that peanut butter can be an excellent addition to your diet.

Why Do We Love Peanut Butter?

I firmly believe that nut butter is the greatest uplevel to nuts that's ever happened. 

In truth, there's so much to love about nut butter, in all its glorious variety. Nowadays you can enjoy all sorts of pulverised nuts as a creamy, smooth or crunchy spread. You may commonly see almond butter, cashew butter, Brazil nut butter or different combinations of these together. However, there's a special place in my heart, and my fridge, for peanut butter. It remains the ol' faithful of nut butters that the whole family enjoys.

But, why do we love peanut butter? There's something about the mouthfeel, combined with the flavour of this particular nut butter. It bestrides both savoury and sweet territories, which means no matter what your craving is, peanut butter is there to help.

Peanut butter is a perennial favourite because it's also the most affordable among the lot. Trends may come and go for other nut butter varieties (which are delicious and also healthy), but sometimes your budget doesn't allow for these indulgences. It's also popular among fitness enthusiasts due to its high protein content. It contains sulphur-based amino acids like cysteine and methionine, which give it a unique and delicious umami flavour that cannot be found in other nut butters.

What Goes Into Your Peanut Butter?

It's pretty simple. As all good things should be. Peanut butter in its purest form is just ground nuts. The peanuts can be roasted (highly recommended) and a pinch of salt can be added to augment its flavour and natural richness. It's your choice whether to go for crunchy or smooth, or even something in between. Either way, the health benefits are the same. Just be sure to check the ingredients list for any extra additions, such as sugar, vegetable oil or stabilisers. None of this stuff is needed, and you're unlikely to see these ingredients used in high-quality nut butter brands and providers.

Nutrient Content & Health Benefits of Eating Peanut Butter

Let’s discuss some of the health benefits associated with eating peanut butter.

Peanuts, and relatedly peanut butter, are an excellent source of plant-based protein, healthy fats, and essential nutrients. Peanut butter is a good source of dietary fibre, is rich in protein, and is also a good source of magnesium, potassium, zinc and other minerals. Vitamin E, choline, resveratrol and antioxidants all appear abundantly in peanut butter as well.

Here's a breakdown of the nutrient content of peanut butter.

Research On The Health Benefits of Peanut Butter Consumption

There is a decent body of evidence showing peanut butter as being a healthful addition to any diet. The macronutrient content (fats, carbs, protein) as well as the phytochemical profile all account for the health-giving benefits of peanut butter. Scientific data reveals that peanut butter can help with brain function and development, mood regulation, hormone health, and cardiovascular function and can also reduce the risk of the onset of certain cancers.

Here's what some of the studies show.

Peanut butter is rich in the vitamin-like compound, choline, which is important for cell membrane function and brain health. In fact, choline is an essential compound needed for new brain cell growth (neurogenesis), with recent research suggesting that choline may be just as important as folate for proper foetal development during pregnancy.

Peanut butter demonstrates anti-cancer and anti-inflammatory properties. A 2021 study from Advances in Nutrition revealed that eating tree nuts and peanuts can help lower the risk of getting various types of cancer, including colon, breast cancer and pancreatic cancer.

Peanut butter has been shown to increase the bioavailability of certain vitamins in other foods. A meta-analysis study from 2017 showed that the consumption of peanut butter helps with the conversion of beta-carotene into vitamin A. This nutrient is important for vision as well as immune and respiratory function.

Peanut butter consumption is also directly correlated to better cognitive function, according to a recent study published in The Journal of Prevention of Alzheimer's Disease. Researchers found that participants who did not eat peanuts or peanut butter were more likely to do poorly on 3 different cognition and memory tests compared to those who did eat peanuts or peanut butter.

Peanuts are high in resveratrol, flavonoids and plant sterols, which are polyphenols known for their disease-preventing properties and promotion of longevity. Many of these bioactive compounds exert a stronger antioxidant effect after they’ve been exposed to heat. Researchers found that skin-on roasted peanuts have an increased resveratrol potency of up to 75%. This translates to a powerful protective action on the cardiovascular system.
