Parsnips by Woolworths has 84 kcal, 18 g carbs, 1.2 g protein and 0.3 g fat per serving (100g).
Woolworths Parsnips are a versatile root vegetable, providing a sweet and earthy flavor profile. With 18g of carbohydrates per 100g serving, they offer a moderate glycemic load, making them a suitable option for endurance athletes looking to maintain energy levels. Parsnips are particularly beneficial for athletes who prefer whole food sources of carbohydrates. They are best consumed before or after workouts, providing a steady release of energy. Their fiber content aids in digestive health, though it may slow gastric emptying if consumed too close to intense exercise. Parsnips are ideal for athletes who need a nutrient-dense, low-fat carbohydrate source to fuel training or recovery.
- Moderate glycemic carbohydrate source
- Rich in dietary fiber
- Low in fat and sodium

The numbers that matter on a training day
For endurance who it suits
For endurance athletes, parsnips offer a moderate carbohydrate source with added fiber benefits. While they are not suitable for immediate energy needs during exercise, they can be a valuable part of a pre- or post-exercise meal. Their potassium content aids in muscle function, but the absence of sodium means they should be paired with other sodium-rich foods or drinks, especially for athletes with high sweat losses.
Parsnips are ideal for endurance athletes such as marathon runners, cyclists, and triathletes who require a moderate glycemic carbohydrate source for sustained energy. They are also suitable for athletes who prefer whole food options and are looking to increase their intake of dietary fiber. Additionally, parsnips can be a good choice for those managing sodium intake.
Parsnips are best suited for pre-workout meals or post-workout recovery sessions where moderate carbohydrate intake is desired. They can be paired with protein sources for recovery or consumed as part of a balanced meal before long, steady-state endurance sessions.
- Moderate glycemic index for sustained energy
- High in dietary fiber for digestive health
- Rich in potassium for muscle function
- Low in fat and sodium, suitable for heart health
- Not suitable for immediate energy needs
- High fiber content may cause GI distress during exercise
- Lacks sodium for electrolyte replacement
- Potential GI distress if consumed close to exercise
- Lack of sodium may require additional supplementation
Fuelling science in short
Not recommended during workouts due to their solid form and fiber content, which may slow gastric emptying and cause gastrointestinal discomfort.
Parsnips have a moderate glycemic index, providing a slower release of glucose into the bloodstream. This can help maintain energy levels during prolonged activities but may not be ideal for immediate energy needs.
Parsnips contain 375 mg of potassium per serving, supporting muscle function and fluid balance. They lack sodium, which is crucial for athletes with high sweat rates.

Parsnips are best used outside of immediate pre-race and during-race contexts due to their fiber content and solid form. They offer benefits in recovery and everyday training when paired with protein and sodium sources. Their moderate glycemic index supports sustained energy release, making them suitable for carb loading with caution due to potential satiety issues.
CAUTION: Consume 2-3 hours before race start due to fiber content, which may slow gastric emptying and cause GI distress if consumed too close to the event.
DO NOT USE: Solid form and fiber content are unsuitable for mid-race consumption, potentially causing GI distress.
USE: Provides carbohydrates and potassium for recovery, but should be paired with protein for muscle repair.
- Pair with sodium-rich foods for electrolyte balance
- Combine with lean protein for recovery meals
- Add to mixed vegetable dishes for nutrient diversity
For practitioners the evidence
Evidence grade: B — Supported by general nutritional data and physiological principles, but lacking direct RCT evidence specific to endurance athletes.
Parsnips, with 18g of carbs per 100g serving, have a moderate carb density. For a 70kg athlete aiming for 600g of carbs daily, a single 100g serving contributes only 18g, necessitating impractical large volumes due to satiety from fiber. Thus, while they can be part of a carb-loading diet, reliance on them alone is inefficient. Their fiber content may also cause gastrointestinal discomfort if consumed in large quantities.
Parsnips are primarily digested in the small intestine, where carbohydrates are broken down into glucose molecules and absorbed via the SGLT1 transporter. The moderate fiber content can slow gastric emptying and may cause GI distress if consumed in large amounts close to exercise. The glucose from parsnips enters the bloodstream gradually, providing a steady energy release, which is beneficial for endurance activities but not for immediate energy needs.
Parsnips can contribute to recovery by replenishing glycogen stores due to their carbohydrate content. However, they lack protein, which is critical for muscle protein synthesis post-exercise. Pairing them with protein-rich foods can enhance recovery. The potassium content supports muscle function and fluid balance, but additional sodium may be necessary to fully address electrolyte losses.
The high fiber content of parsnips may lead to gastrointestinal discomfort if consumed in large quantities or too close to exercise. They are not suitable for rapid glycogen replenishment due to their moderate glycemic index. Additionally, the lack of sodium makes them insufficient for electrolyte replacement without additional sources.
- Do not use within 90 minutes of race start due to high fiber content and potential GI distress.
- Do not rely on parsnips alone for carb loading due to low carb yield per serving.
- Do not use during high-intensity sessions requiring rapid energy availability.
- High fiber content may cause bloating and GI distress during exercise.
- Lack of sodium can lead to inadequate electrolyte replenishment during prolonged activities.
- Moderate glycemic index may not provide rapid energy spikes needed for intense efforts.
- Potential for dental erosion if consumed frequently due to natural sugars.
Questions about Parsnips
How many carbs are in Parsnips by Woolworths?
18 g of carbs per serving (100g), with 84 kcal and 1.2 g protein.
When should I consume parsnips for endurance training?
Consume parsnips 2-3 hours before training to allow for digestion and avoid GI distress due to their fiber content.
Are parsnips suitable for during-race consumption?
No, parsnips are not suitable during races due to their solid form and fiber content, which may cause gastrointestinal discomfort.
How should I prepare parsnips for optimal nutrition?
Roast, boil, or steam parsnips to retain their nutrients. Pair with protein and sodium-rich foods for balanced meals.
Can parsnips be part of a recovery meal?
Yes, parsnips can be part of a recovery meal when combined with protein sources to aid muscle repair and replenish glycogen.
Do parsnips provide enough electrolytes for athletes?
Parsnips provide potassium but lack sodium, so additional sodium sources are needed to meet electrolyte needs during intense exercise.
What are alternatives to parsnips for endurance athletes?
Alternatives include sweet potatoes and carrots, which offer similar carbohydrate content with varying glycemic indices and nutrient profiles.
