Introducing
Our Tasty Trio
White Mushrooms
White mushrooms are the most well-known and widely consumed mushrooms in New Zealand and around the world. Mushrooms are packed with minerals and vitamins, and they're also low in calories.
They make a fantastic addition to all your meals! You can sauté, grill, steam, and bake white mushrooms, or simply enjoy them raw.
Swiss Brown
Mushrooms
Swiss brown mushrooms may resemble white mushrooms at first glance, but they're just a bit different. Of course, you can spot the distinction by their rich brown color, but their unique qualities don't end there. Their flesh is firmer, and their flavor is slightly more robust, with a hint of nuttiness. Swiss brown mushrooms contain slightly less moisture, resulting in less shrinkage when cooked.
Portobellos
The portobello mushroom, known as the big brother of the Swiss brown mushroom, boasts an intense and robust flavor that elevates any dish it graces. Its meaty texture and versatile nature make it a beloved choice among mushroom lovers. Whether stuffed or used as a meat substitute, the portobello's meaty texture and rich taste add depth and satisfaction to every bite, earning it a cherished place in the hearts of many culinary enthusiasts.
Healthy
Understanding the unique health benefits of Mushrooms…
Button mushrooms have many qualities. They are rich in nutrients such as B-vitamins and C-vitamins. Also rich in minerals such as potassium, copper and iron.
White button mushrooms specifically, also contain dietary fibre, which is essential for your digestive health, and antioxidants that may help combat oxidative stress in the body.
More Energy
We need B-vitamins for more energy, and mushrooms deliver them on a silver platter. Especially white mushrooms contain a fair amount of vitamin B2 and B3. Many mushrooms are rich in the mineral copper, which is also beneficial for your energy levels.
Strong Immunity
There is evidence that mushrooms can strengthen our immunity. They do this by nourishing the beneficial bacteria in our intestines. Considering that about 80 percent of our immunity resides in our intestines, you understand that mushrooms can contribute to a robust immune system. So, make sure to use mushrooms abundantly in various dishes, from pasta sauce to vegetable omelets.
Caring for your heart
All mushrooms contain a type of fiber that improves your cholesterol levels and keeps your heart healthy. Additionally, the mineral potassium is present in large quantities in mushrooms. Portobellos, in fact, contain as much potassium as bananas. This mineral plays a crucial role in maintaining heart health.
Good for your weight
Mushrooms have high nutritional value and are virtually calorie-free. This is perfect if you're looking to lose weight or maintain a healthy weight. With few calories, you get a lot of nutrients, keeping you satisfied for longer periods. As a result, you're less likely to reach for unhealthy snacks. The fibers in mushrooms, which are healthy for your heart, also help to keep your blood sugar levels balanced. This reduces the risk of developing diabetes type 2.
Beneficial to your overall health
While brightly colored vegetables and fruits are often praised for their abundance of cell-protecting antioxidants, don't forget about portobello mushrooms. These mushrooms contain as many antioxidants as red peppers.
