What You'll Learn
- Cooking methods: Nutrient retention varies with cooking methods
- Portobello mushrooms: One cup of grilled Portobellos has 35 calories

- White mushrooms: One cup of stir-fried slices has 28 calories
- Shiitake mushrooms: One cup of cooked shiitake has 81 calories

Cooking methods: Nutrient retention varies with cooking methods
The cooking method used can significantly impact the nutrient content of food. For example, grilling or broiling meat can result in a loss of up to 40% of B vitamins and minerals as the nutrient-rich juices drip away. Grilling also generates potentially carcinogenic substances called polycyclic aromatic hydrocarbons (PAHs) when fat drips onto a hot surface. However, researchers have found that PAH levels can be decreased by 41-89% if drippings are removed and smoke is minimised.
Water-soluble vitamins, such as vitamin C and the B vitamins, are often reduced during cooking. Boiling, simmering, and poaching vegetables in water can lead to a significant loss of these vitamins as they dissolve and leach out into the cooking water. However, you can still benefit from these nutrients by consuming the cooking water or using it as a soup stock.
On the other hand, microwaving is a cooking method that generally preserves most nutrients due to shorter cooking times and reduced exposure to heat. Studies have found that microwaving is the best method for retaining the antioxidant activity of garlic and mushrooms. Similarly, steaming vegetables can help retain vitamin C content, with higher retention observed after microwaving compared to boiling.
Roasting or baking in an oven with dry heat has minimal impact on most vitamins and minerals, except for B vitamins, which can decline by up to 40% due to longer cooking times at high temperatures. Stir-frying, on the other hand, uses higher heat for shorter periods, minimising nutrient loss.
In terms of mushrooms specifically, it is recommended to cook them before consumption as their cell walls are made of chitin, which is difficult for humans to digest. While cooking mushrooms may reduce some nutrients, most constituents are fully retained or retained at 80-95% of their levels in raw mushrooms. For example, a cup of stir-fried white mushrooms retains 12% of the daily value for potassium and 2% for iron while providing 28 calories. Grilled portobello mushrooms offer 35 calories and 3.9 grams of protein, while retaining 529 mg of potassium.
To summarise, different cooking methods can impact the nutrient content of food in various ways. Grilling and boiling may result in greater nutrient loss, especially for water-soluble vitamins, while microwaving, steaming, stir-frying, and roasting tend to preserve more nutrients. When aiming for 1000 calories from mushrooms, the cooking method chosen will influence the amount needed, with grilled portobellos providing slightly more calories per cup than stir-fried white mushrooms.

Portobello mushrooms: One cup of grilled Portobellos has 35 calories
Portobello mushrooms are large, meaty mushrooms that are often grilled and used as a meat substitute. They are a good source of plant-based protein, vitamins, and minerals.
One cup of grilled Portobello mushrooms contains approximately 35 calories. This serving size also provides 3.9 grams of protein, 2.7 grams of fiber, and 529 mg of potassium. The same portion has 3.87 milligrams of niacin and 0.13 milligrams of vitamin B6, which is 7% of your recommended dietary allowance (RDA).
Portobello mushrooms are a low-calorie food, with an average of only 18 calories per 3-ounce serving (about one mushroom). This makes them a great option for people watching their weight, as they can be consumed in larger quantities without adding too many calories. For example, a 3-ounce serving of cooked ground beef has 218 calories, while the same amount of Portobello mushrooms would have only 18 calories.
The low-calorie nature of Portobello mushrooms also makes them a good choice for grilling instead of high-calorie foods like hamburgers. By substituting two Portobello mushroom caps for a hamburger, you can save more than 150 calories without sacrificing taste or satisfaction.
While the focus is on grilled Portobellos in this prompt, it is worth noting that the calorie count and nutritional profile of mushrooms can vary slightly depending on their preparation and cooking methods. For example, one cup of diced Portobello mushrooms provides slightly different nutrient amounts than grilled Portobellos. Additionally, marinated and sautéed Portobellos, or those stuffed with other ingredients, will also contribute additional calories and nutrients to a meal.
