Remember when you were a child and your mother told you to eat your vegetables? Turns out mom knew what she was talking about. Vegetables provide a nutritional powerhouse, packed as they are with vitamins, minerals and phyto-chemicals. That is why you will find that vegetables form a key part of virtually every diet out there.

Vegetables are also a key part of the keto diet. However, those veges that are high in carbohydrates need to be approached with extreme caution. Even though they may be healthy, they will also kick you out of the state of ketosis – the fat burning basis upon which the ketogenic diet is formed.

So, what about the humble asparagus?

In this article we provide the definitive answer to the question whether asparagus belongs on the keto diet. We also provide a comprehensive asparagus-keto FAQ, along with one of our favorite recipes!

Asparagus Facts

Asparagus is one of the most welcome signs of spring. For centuries it was used as an aphropdisiac. The ancients didn’t know why asparagus boosted virility, but today we do. This tasty vegetable happens to be packed with nutrients that enhance our energy, optimize our urinary tract and negate the build-up of ammonia. Too much ammonia can make us lethargic and diminish our sexual interest. Asparagus has the power to help turn that around.

These include vitamin C, beta-carotene, vitamin E, and the minerals zinc, manganese and selenium.

Asparagus represents a great food choice for your brain health. One reason is that it contains the amino acid Asparagine, from which the vegetable derives its name. Asparagine has been shown to play a important role in the development and functioning of the brain. It’s also a good source of chromium, which helps insulin to do its job of transporting glucose.

Asparagus is an especially rich source of glutathione, which has been shown to be an effective carcinogen. For this reason, asparagus often gets added to the diet of people who are suffering with cancer.

Health Benefits

Asparagus is good news for your heart. It has high rates of Vitamin K, which can help to alleviate blood clots. This is backed up with generous levels of Vitamin B, which are able to regulate an amino acid called homocysteine. This amino acid poses a serious risk for heart disease.

Every cup of asparagus provides you with more almost two grams of soluble fiber. This also helps to lower your risk of heart disease. The high levels of asparagine contained in asparagus also flushes out salt from the system.

vitamin b6 asparagusAsparagus contains high levels of Vitamin B6, which has been shown to help regulate blood sugar. This vegetable can also benefit people who have Type 2 Diabetes. This is due to its high levels of antioxidants and anti-inflammatories. According to a number of studies, including a 2011 study in the British Journal of Nutrition, the ability to enhance insulin secretion and improve beta-cell function will also reduce the risk of Type 2 Diabetes.

The high levels of glutathione in asparagus are good to prevent the signs of aging. The combination of folate and Vitamin B12 also help stave off cognitive decline. Glutathione also protects the skin from sun damage.

According to a 2010 study, asparagus can also act as a natural diuretic by helping to flush excess salt and fluid from the body. This is especially beneficial for people with edema and high blood pressure. It is also known to flush toxins from the body and to help prevent kidney stones. However, it should be noted that people who suffer from uric acid kidney stones should not consume asparagus.

Because of its high fiber content, asparagus is excellent for the digestive system. It will help to move your food through your gut and help to bring relief from digestive issues such as belching and flatulence. Asparagus contains an important pre-biotic known as inulin, which does not get broken down until it reaches the large intestine. Once in the large intestine, inulin helps to develop the good bacteria that promotes gut health.

Asparagus also contains saponins in high amounts. Saponins contain both fat-soluble and water-soluble compounds. These are known to have a positive effect on cell membranes and improve the body’s immunity. Recent studies also suggest that saponins from asparagus may help to prevent secondary tumor formation.

Asparagus, Leek, and Herb Frittata with Fresh Goat Cheese 

Whisk together 7 large eggs; 1 tablespoon each chopped fresh tarragon leaves, finely chopped fresh chives, and chopped fresh mint leaves; 1 teaspoon freshly grated lemon zest; ½ teaspoon  Dijon mustard; ½ teaspoon fine sea salt; and ⅛ teaspoon freshly  ground black pepper.

Heat 2 tablespoons olive oil in a medium- size, ovenproof, non-stick skillet over medium heat. Add 1 large  leek, washed well, and patted dry, dark green tops discarded,  sliced into ⅛-inch-thick half-moons, and cook, stirring often, until they begin to soften. Stir in ½ bunch asparagus, cut into 1- inch lengths, and another ¼ teaspoon salt and ⅛ teaspoon pepper, and cook, stirring occasionally, until just tender, 3 to 5 minutes.

Reduce the heat to medium low. Add the egg mixture and gently shake the pan to distribute. Cook, occasionally pulling the edges away from the pan with a silicone spatula, allowing uncooked egg to run underneath, until the edges are set and the  center is just beginning to set (it should still be mostly runny), 8  to 10 minutes.
