About it

Woolworths Sliced Button Mushrooms are a low-calorie, high-fiber food option, providing 19.6 kcal per serving (100g). With a mild, woody flavor, these mushrooms are versatile in culinary applications but are not a primary energy source for endurance athletes. They contain minimal carbohydrates (1g per serving) and protein (2.1g per serving), making them more suitable as a dietary fiber source rather than a carbohydrate or protein provider. Consumed post-training, they can contribute to dietary fiber intake and aid digestion, but they lack the necessary macronutrients for immediate recovery or energy replenishment. Their low sodium content (6mg per serving) is insufficient to replace sweat losses during prolonged endurance activities. Therefore, they should be paired with other nutrient-dense foods for optimal recovery and energy replenishment.

How we read foods ›

For endurance who it suits

Endurance verdict

While Woolworths Sliced Button Mushrooms offer dietary fiber and a low-calorie profile, they lack the macronutrients necessary for endurance performance. They are best used as part of a balanced diet in conjunction with other nutrient-dense foods. For endurance athletes, these mushrooms should be consumed post-exercise as part of a meal that includes adequate carbohydrates and protein for recovery.

Who it is for

These mushrooms are ideal for endurance athletes looking to increase their dietary fiber intake without adding significant calories. They are suitable for athletes in a maintenance phase or those focusing on weight management. They can be incorporated into meals for those who require a low-calorie, high-fiber food option, but should not be relied upon for energy or protein needs.

Best sessions

Best used in recovery meals or as part of a balanced diet on rest days. They are not suitable for fueling during high-intensity or long-duration sessions due to their low carbohydrate content.

Pros

Low in calories, aiding weight management
High in fiber, supporting digestive health
Versatile in cooking, suitable for various dishes
Minimal sodium content, reducing hypertension risk

Cons

Insufficient carbohydrates for energy needs
Low protein content, inadequate for recovery
Not suitable for during-exercise consumption

Watch out for

Potential for gastrointestinal discomfort if consumed in large quantities
Lacks significant macronutrients for recovery or performance

Fuelling science in short

During a session

No, these mushrooms are not practical for during-workout consumption due to their low carbohydrate content and solid form, which is not conducive to quick digestion or energy provision.

Glycaemic profile

With only 1g of carbs per serving, these mushrooms have a negligible impact on blood sugar levels. They do not provide a significant glycemic load, making them unsuitable as a quick energy source.

Electrolytes

Contains 6mg of sodium per serving, which is negligible compared to the 300-600mg/hr sodium loss in sweat. Not a source of potassium or magnesium.

Woolworths Sliced Button Mushrooms are not suitable for pre-race, during-race, or recovery due to their low carbohydrate and protein content. They do not provide the necessary nutrients for energy or recovery. However, they can be used in everyday training meals as a low-calorie, high-fiber option to support overall dietary goals.

NOT RECOMMENDED for pre-race use because they provide minimal carbohydrates and energy, which are essential for optimal performance. Their fiber content may also slow gastric emptying.

For practitioners the evidence

Evidence grade: C — The analysis is based on general nutritional data and lacks specific clinical trials directly supporting endurance performance claims.

In a carb load

Woolworths Sliced Button Mushrooms are unsuitable for carb loading due to their low carbohydrate density of 2g per 100g. A serving contributes only 1g of carbohydrates, which is negligible towards the 600-840g daily target for a 70kg athlete. The athlete would need to consume an impractical volume to meet carb loading needs, making them ineffective for this purpose.

Digestion and absorption

These mushrooms have a low glycemic impact due to minimal carbohydrate content. They undergo typical digestive processes with fiber potentially slowing gastric emptying. The low carbohydrate content results in negligible glucose absorption, with any sugars present being absorbed via GLUT5 transporters. The fiber content may contribute to colonic fermentation, supporting gut health but not energy provision.

Recovery

Woolworths Sliced Button Mushrooms do not contribute effectively to the recovery window. They provide minimal carbohydrates and protein, insufficient for glycogen resynthesis or muscle protein synthesis. They lack sodium for rehydration and do not offer significant antioxidant or anti-inflammatory compounds. As such, they are inadequate as a standalone recovery food.

Downsides

The low carbohydrate content of these mushrooms makes them unsuitable for energy provision during exercise. High fiber content may cause gastrointestinal discomfort if consumed in large amounts. They pose no significant dental erosion risk but do not contribute to blood glucose stability. Their low sodium content is insufficient for replacing sweat losses in endurance athletes.

Don't use it when

Do not use for carb loading due to low carbohydrate density.
Do not use during races for energy provision; they are a solid food with low carbs.
Do not rely on them for recovery; they lack sufficient macronutrients.

Clinical risks

Low carbohydrate content fails to meet energy needs during endurance events.
High fiber content may slow gastric emptying, unsuitable pre-race.
Negligible sodium content does not replace sweat losses in hot conditions.
Inadequate protein content fails to support muscle protein synthesis post-exercise.
