Key takeaways

  • Contains 35g of sugar per 100g
  • Maize is a high glycemic index carbohydrate
  • Contains peanut allergens
  • Provides only 6g of protein per 100g
  • High sodium content at 300mg per 100g

Our read on this product

With 35g of sugar per 100g, Crunchy Nut by Kellogg's is primarily a source of refined energy rather than dense nutrients. The combination of maize, sugar, and molasses leads to a rapid glycemic spike that negatively impacts blood glucose regulation. While the inclusion of peanuts adds some healthy fats, they are insufficient to offset the high sugar and sodium content of 300mg.

Best for

This product is suitable only for individuals looking for a dessert-like, occasional treat who do not have specific blood sugar or weight management concerns.

Approach with care

Individuals with diabetes, insulin resistance, or gluten sensitivities, as well as those actively trying to lose weight, should avoid this product.

Ingredients to watch

sugar: Watch out
molasses: Watch out
salt: Watch out
Neutral

Maize

Maize is a cereal grain used as the primary source of carbohydrates in this cereal. It provides energy but contributes to a high glycemic load, which can trigger insulin spikes.

Watch out

sugar

Added as a sweetener to improve flavor and texture. High intake of refined sugar is strongly linked to systemic inflammation and the exacerbation of acne symptoms.

Neutral

barley malt extract

Derived from sprouted barley, this provides flavor and natural coloring. It contains gluten, which may affect sensitive individuals, and is a source of simple sugars.

Good

peanuts

These legumes provide healthy fats, plant protein, and fiber. They are a nutrient-dense addition but are high in calories and common allergens.

Watch out

molasses

A byproduct of sugar refining, it adds a distinct flavor and some trace minerals. Despite being less refined than table sugar, it still functions as a concentrated source of sugar.

Neutral

honey

Used as a natural sweetener, it provides trace antioxidants and enzymes. However, it is fundamentally a high-sugar ingredient that impacts blood glucose levels.
