About it

Woolworths Sliced Portabellini Mushrooms offer a convenient, low-calorie option for athletes seeking to enhance their daily nutrition with whole foods. Each 100 g serving provides 32 kcal, 2.7 g of carbohydrates, 2.4 g of fiber, and 2.3 g of protein, making them a nutrient-dense addition to meals. While they are not suitable as a primary energy source during intense training or racing due to their low carbohydrate content, they can contribute to a balanced diet by providing essential micronutrients and fiber. These mushrooms are best consumed as part of a meal before or after training sessions, rather than as a standalone snack during exercise. Their high fiber content may slow gastric emptying, making them less suitable for immediate pre-race or mid-race consumption.

For endurance who it suits

Endurance verdict

Woolworths Sliced Portabellini Mushrooms are a nutritious addition to an endurance athlete's diet, offering low-calorie, high-fiber benefits. However, they are not suitable as a primary fuel source during intense training or racing due to their low carbohydrate content. Best used in everyday meals to support overall nutrition.

Who it is for

Sliced Portabellini Mushrooms are ideal for endurance athletes looking to enhance their daily nutrition with low-calorie, nutrient-dense foods. They are suitable for those aiming to increase their fiber intake and add variety to their meals. However, they are not recommended for athletes seeking high-energy foods for intense training or racing.

Best sessions

Best suited for everyday meals and recovery days. Not ideal for high-intensity sessions or races due to low carbohydrate content.

Pros
  • Low calorie, nutrient-dense option
  • High in dietary fiber
  • Conveniently pre-sliced for easy use
  • Versatile addition to various meals
Cons
  • Low carbohydrate content for endurance fuel
  • High fiber may slow gastric emptying
  • Not suitable for pre-race or mid-race consumption
Watch out for
  • Potential GI distress if consumed in large quantities pre-race
  • Low sodium content may not meet electrolyte needs

Fuelling science in short

During a session

No, not recommended during workouts. Low carb content and high fiber may cause GI distress.

Glycaemic profile

Low glycemic impact due to minimal carbohydrate content. Slow gastric emptying from fiber may delay glucose availability.

Electrolytes

Contains 11 mg of sodium per serving, insufficient to replace sweat losses during endurance activities. Potassium content is unspecified.

  • Carb loadDO NOT USE
  • Every dayUSE

Sliced Portabellini Mushrooms are not suitable for pre-race or during-race consumption due to their low carbohydrate content and high fiber, which can slow gastric emptying and cause GI distress. They can be used cautiously in recovery when paired with other macronutrient-rich foods. Their best use is in everyday training meals to support overall nutrition without providing significant energy for endurance activities.

NOT RECOMMENDED for pre-race use because the high fiber content may slow gastric emptying and delay carbohydrate availability, potentially causing GI distress.

Pair it with
  • Pair with whole grains for balanced meals
  • Combine with lean proteins for recovery
  • Add to salads for increased fiber intake

For practitioners the evidence

Evidence grade: C — Limited evidence directly supports the use of mushrooms for endurance fueling; conclusions are based on general nutritional principles.

In a carb load

Sliced Portabellini Mushrooms have a low carbohydrate density of 2.7 g per 100 g, making them unsuitable for carbohydrate loading. A 100 g serving contributes only 2.7 g towards a 600 g daily target for a 70 kg athlete, necessitating impractical consumption volumes. Their high fiber content may also lead to early satiety, preventing effective carb loading.

Digestion and absorption

The digestion of Portabellini Mushrooms begins with mastication, followed by gastric emptying, which may be slowed due to the high fiber content (2.4 g per 100 g). Carbohydrates are minimally present, with no significant glucose or fructose. Protein is absorbed via brush-border peptidases. The fiber may undergo fermentation in the colon, potentially causing bloating or gas if consumed in excess.

Recovery

While Portabellini Mushrooms provide some protein (2.3 g per 100 g), they lack sufficient carbohydrates to meet the 1.0-1.2 g/kg/h glycogen resynthesis target. They should be paired with a higher carbohydrate and protein source to support recovery. The fiber content may aid in satiety and digestive health, but does not directly contribute to muscle recovery.

Downsides

The high fiber content can lead to GI distress if consumed in large quantities pre-race. Low carbohydrate content may lead to inadequate energy supply during exercise. Their low sodium content is insufficient for replacing sweat losses. Not suitable for athletes with IBS or those sensitive to high-fiber foods.

Don't use it when
  • Do not use within 90 minutes of race start due to high fiber content.
  • Do not use as a primary carbohydrate source for carb loading.
  • Do not rely on for sodium replacement during endurance events.
Clinical risks
  • High fiber content may cause GI distress during exercise.
  • Low sodium content may not meet electrolyte needs during long events.
  • Inadequate carbohydrates for endurance fueling.
  • Potential bloating from fiber fermentation in sensitive individuals.
