Both nut butters should be consumed in moderation. The calories in any nut butter add up pretty fast by eating too much.

Including peanut butter as part of a well-balanced nutrition plan will help gain the maximum weight loss benefits.

Low-carb or Keto Diet

If your goal is a Keto or low-carb diet then carbohydrates are your number one concern. If you’re on a low-carb diet, you may ask which has more carbohydrates, peanut butter or cashew butter?

Cashew Butter vs Peanut Butter: Glycemic Index

The Glycemic Index (GI) is a scale measuring how fast a particular food raises the blood sugar in the blood 5. Blood sugar spikes can lead to health complications with the heart, nerves, kidneys and eyes 6

The glycemic index of food is important. Avoiding blood sugar spikes is an important part of consuming healthy food. This is true for diabetics or anyone worrying about their health.

Foods on the GI scale are categorized as:

  • Low-GI foods: 55 or under
  • Medium-GI foods: 56-69
  • High-GI foods: 70 or over

How blood sugars levels are affected:

  • Foods with a glycemic index 70 or more cause a quicker spike in blood sugar levels.
  • Foods with a glycemic index 56 to 69 cause a moderate spike in blood sugar levels.
  • Foods with a glycemic index 55 or less cause a slow spike in blood sugar levels.

Now we know what the glycemic index of food is and how it raises blood sugar, many people ask, does cashew butter or peanut butter have a higher glycemic index?

Peanut butter has a lower glycemic index than cashew butter although both are considered low glycemic foods. Peanut butter has a glycemic index of 14, and cashew butter has a glycemic index of 22.

The Satiety Index of Cashew Butter and Peanut Butter

Satiety is a term used to explain the loss of appetite and the feeling of being full after eating food. The satiety index is a scale showing how full a person feels after eating certain foods. 

The satiety index was developed in 1995 from a study. The researchers tested 38 foods which were ranked how they satisfied a person’s hunger. Foods scoring above 100 are considered more filling and foods scoring under 100 are considered less filling 7.

The table below shows the satiety scores of some foods noted in the study.

Snack Satiety Index Score
Mars candy bar 70%
Peanuts 84%
Bananas 118%
Brown Rice 132%
Lentils 133%
Eggs 150%
Popcorn 154%
Oatmeal 209%
Boiled potatoes 323%

Unfortunately, they didn’t test cashew butter or peanut butter. Even though other studies have determined peanut butter is good for satiety.

Purdue University published a study testing the satiety of peanut butter and peanuts against a non peanut meal. Peanut butter resulted in the lowest desire to eat cravings than peanuts or the non peanut meal.

Peanut butter enhanced gut satiety hormone secretion and reduced the desire to eat the best of all three food options 8

A study released recently found tree nuts, like cashews, does not stimulate weight gain even though they contain a good amount of calories. The researchers noted the ingestion of nuts can help in the control of satiety 9.

High satiety food is likely to have a high satiety score for the following reasons:

  1. High in protein.
  2. High in fiber.
  3. High in volume (foods containing a lot of water or air).
  4. Low in energy density (foods low in calories for their weight).

Peanut butter and cashew butter are high in protein, fiber and weight satisfying three of the four reasons above.

Cashew Butter vs Peanut Butter: Health Benefits

The similar nutrients contained in both nut butters offer the same type of benefits. One nut butter may help some of these benefits more if the percentage is higher.

The following describes how each nutrient may benefit health and how much more each butter provides than the other.

Minerals

Peanut butter has a higher percentage of minerals than cashew butter. Let’s take a closer look at some of these minerals and how they benefit health.

Potassium

  • Peanut butter contains 564 mg of potassium per 100 grams.
  • Cashew butter contains 546 mg of potassium per 100 grams.

Peanut butter provides 3.4% more potassium than cashew butter per 100 grams.

Some medical experts recommend the potassium to sodium ratio of 4:1. Consuming too much sodium or not enough potassium throws off the delicate balance the kidneys need to remove the excess water 10.

Potassium helps the body get rid of excess sodium reducing fluid build-up. These help keep systolic and diastolic blood pressure lower 11.

According to Harvard Health, a number of studies have shown a connection between low potassium levels and high blood pressure 12. The more potassium, the more sodium your body will lose.

Magnesium

  • Peanut butter contains 270 mg of magnesium per 100 grams.
  • Cashew butter contains 258 mg of magnesium per 100 grams.

Peanut butter provides 4.7% more magnesium than cashew butter per 100 grams.

Magnesium helps keep blood pressure levels stable and balanced. Recent scientific research examined previous studies and concluded magnesium supplementation decreased systolic and diastolic blood pressure 13.

Magnesium helps control the following:

  • Blood sugar
  • Nerve function
  • Insomnia
  • Muscle
  • Blood pressure

In the heart and muscles, magnesium competes with calcium to help the muscles relax after contracting. When the body is low in magnesium, calcium can over stimulate the heart muscle’s cells causing a rapid or irregular heartbeat 14.

One reason many people supplement with magnesium in the evening is because it helps calm the whole body including blood vessels.

Calcium

  • Peanut butter contains 62 mg of calcium per 100 grams.
  • Cashew butter contains 43 mg of calcium per 100 grams.

Peanut butter provides 44% more calcium than cashew butter per 100 grams.

Calcium is important for the heart and blood pressure. Harvard Health reports calcium helps maintain blood pressure by helping in the controlling of the relaxing and tightening of blood vessels 15.

Calcium also helps the following:

  • Helps nerve function.
  • Maintain and build strong bones.
  • Help the muscles to function properly.

Iron

  • Cashew butter contains 5.03 mg of iron per 100 grams.
  • Peanut butter contains 3.10 mg of iron per 100 grams.

Cashew butter provides 63% more iron than peanut butter per 100 grams.

Iron is essential in the creation of red blood cells and is a necessary part of any healthy diet. Iron is also vital for growth and development, as some hormones need iron to be appropriately balanced 16. 

Phosphorus

  • Peanut butter contains 481 mg of phosphorus per 100 grams.
  • Cashew butter contains 457 mg of phosphorus per 100 grams.

Peanut butter provides 5.2% more phosphorus than cashew butter per 100 grams.

Phosphorus has been shown in scientific studies to help with the following:

  • Promote healthy nerve conduction.
  • Promote bone and teeth strength.
  • Muscle contraction.
  • Muscle recovery.
  • Help the kidneys remove waste.
  • Help the body manage and store energy.

  • Cashew butter contains 2 grams of fiber per 100 grams.

Peanut butter provides 360% more fiber than cashew butter per 100 grams.

Soluble fiber is helpful for many reasons 17. What makes fiber soluble is it dissolves in water. 

Soluble fiber is known for the following:

  • Manage the blood glucose levels which helps decrease the risk of diabetes.
  • Helps avoid constipation and have a more regular stool.
  • Help overall digestive health.
  • Aids greatly in weight management because it allows you to feel full faster and eat less.
