Brown onions from Woolworths are a low-calorie, nutrient-dense ingredient, perfect for athletes seeking to enhance their meal's flavor profile without adding significant calories. With 36.3 kcal per 80 g serving, these onions provide a modest 7.2 g of carbohydrates, including 4.9 g of sugars. They are primarily used as a base in soups, stews, and sauces, making them an excellent choice for athletes looking to prepare hearty meals that support training recovery and energy replenishment. While not a direct source of energy during exercise, onions can contribute to overall dietary diversity and micronutrient intake, such as potassium, which is crucial for muscle function and fluid balance. Due to their low sodium content (8 mg per serving), they are unlikely to impact sodium balance significantly during long endurance sessions.
- Low-calorie, nutrient-dense
- Rich in flavor for meal prep
- Source of potassium for muscle function

The numbers that matter on a training day
For endurance who it suits
While brown onions are not a direct fuel source for endurance events, they are a valuable ingredient for meal preparation, offering flavor and micronutrients. Their low-calorie and low-sodium profile make them suitable for athletes managing weight and dietary sodium intake. However, they should be complemented with other foods to meet carbohydrate and protein needs for recovery.
Brown onions are suitable for endurance athletes looking to enhance their meals with a flavorful, low-calorie ingredient. They are ideal for those preparing meals that require a savory base, such as soups and stews, which can be consumed post-training to aid recovery. Athletes focused on maintaining a balanced diet while managing caloric intake will find them beneficial.
Ideal for post-training meal preparation, particularly after long runs or rides where a hearty, nutrient-rich meal is desired. Not suitable for direct consumption during workouts.
- Low in calories, aiding weight management
- Rich in flavor, enhancing meal taste
- Contains potassium for muscle function
- Versatile in cooking applications
- Low carbohydrate content for direct fueling
- Not suitable for during-exercise consumption
- Minimal protein content for recovery
- Potential for digestive discomfort if consumed raw in large quantities
- Not a significant source of energy or protein
Fuelling science in short
No, brown onions are not practical for consumption during workouts due to their solid form and lack of fast-acting carbohydrates.
Brown onions have a low glycemic impact due to their low carbohydrate content per serving. They are unlikely to cause significant blood sugar spikes, making them suitable for inclusion in a balanced diet.
Each serving provides 8 mg of sodium and 146 mg of potassium, contributing to electrolyte balance but not sufficient to meet the sodium needs during high sweat losses.

Brown onions are not suitable for pre-race or during-race consumption due to their low carbohydrate content and solid form, which can slow gastric emptying and fail to provide immediate energy. However, they are beneficial for recovery meals due to their flavor and micronutrient content, making them a versatile ingredient in everyday training nutrition.
NOT RECOMMENDED for pre-race use because they are low in carbohydrates and do not provide quick energy. Their fibrous nature could also slow gastric emptying.
NOT RECOMMENDED during racing because they are a solid food with low carbohydrate content and do not provide fast-acting energy.
USE in post-race meals as a flavorful base for dishes that include protein and carbohydrates to aid recovery.
- Pair with lean protein for balanced recovery meals
- Combine with whole grains for increased carbohydrate intake
- Add to vegetable stews for enhanced micronutrient profile
For practitioners the evidence
Evidence grade: C — Limited direct evidence on performance impact; nutritional data primarily supports general dietary use.
Brown onions have a low carbohydrate density of 9 g per 100 g, which is insufficient for effective carbohydrate loading. A typical serving of 80 g contributes only 7.2 g of carbohydrates, far below the 600-840 g daily target for a 70 kg athlete. The volume required to meet loading needs would be impractical due to the low carb yield and high satiety effect from fiber content. Therefore, brown onions are not suitable for carb-loading phases.
Brown onions are primarily digested in the small intestine. The carbohydrates present are absorbed via SGLT1 transporters for glucose and GLUT5 for fructose. The fiber content may slow gastric emptying slightly, but the overall low carbohydrate content means they have minimal impact on blood sugar levels. Any unabsorbed fibers may be fermented in the colon, potentially causing gas or bloating in sensitive individuals.
Brown onions provide minimal carbohydrates and no significant protein, making them inadequate as a standalone recovery food. However, they can enhance the flavor of recovery meals that include adequate protein and carbohydrates. The potassium content supports muscle function and fluid balance, but onions should be paired with other foods to meet recovery nutrition targets.
Brown onions can cause gastrointestinal discomfort if consumed in large quantities due to their fiber content. They offer minimal energy and protein, making them unsuitable as a primary fuel source. Additionally, their low sodium content does not support electrolyte replenishment during intense exercise. Athletes with FODMAP sensitivities may experience digestive issues.
- Do not use within 90 minutes of race start due to potential digestive discomfort.
- Avoid during high-intensity sessions as they do not provide quick energy.
- Not suitable for carb-loading due to low carbohydrate density.
- High fiber content may cause bloating or gas in sensitive individuals.
- Low carbohydrate content fails to support glycogen replenishment.
- Minimal sodium content does not aid in electrolyte balance during exercise.
- Potential for digestive discomfort if consumed raw in large amounts.
