What exactly is beetroot? What is their history?

While beetroot and beetroot products are becoming increasingly popular in the natural foods market, beetroot is by no means new. Records show that people in ancient Babylon, Greece and Rome enjoyed eating root vegetables, and archaeologists have also found evidence of their use in certain areas of North Africa. Ancient civilizations originally used beets' leaves and stems for cooking and their roots as medicine. The ancient Greeks and Romans even turned to beets for their aphrodisiac properties.

The closest thing to modern beetroots were first discovered in Germany and Italy in the late 1500s. This form of the vegetable has larger roots and smaller stems and leaves than the ancient version.

In the 1700s, German chemists found a way to make sugar from beets. Today, this method is used on a specific subtype of beet called beetroot, whose roots are much larger than table beets and are white or beige in color. Originating in what is now western Poland, sugar beets came to the United States in the late 19th century as part of increased sugar production in California. Other types of beetroot were brought to the United States much earlier, and historians believe they were introduced by American colonists.

What's in beetroot? Nutritional contents of root vegetables

Beetroot is a low-calorie food that is rich in various nutrients. The following nutritional estimates from the United States Department of Agriculture (USDA) are based on ½ cup of beetroot flakes:

  • Calories: 35
  • Protein: 1 gram (g) (2% of the daily value, or DV)
  • Fat: 0g
  • Carbohydrates: 8 grams
  • Fiber: 1 g (4% DV)
  • Sugar: 6 grams
  • Iron: 0.4 milligrams (mg) (2.22% DV)
  • Sodium: 250 mg

Beetroot is also a source of betaine, an antioxidant evident in its rich red roots. Beetroot is also a great source of manganese, folate and vitamin B2. Beetroot is also a source of potassium, which USDA guidelines say support bones and Muscles contain approximately 259 mg per half-cup serving, which means they provide about 5.5% of the DV.

What are the benefits of eating beetroot?

The health benefits of beetroot are extensive. Like most other plant foods, beetroot is rich in nutrients but low in calories. Their antioxidants also provide additional benefits, such as reducing the risk of cell damage.

Generally speaking, beets are part of a group of vegetables and fruits that may help reduce the risk of chronic diseases, including type 2 diabetes, heart disease and dementia.

Antioxidants give beets their bright red color. As a general rule of thumb, the more brightly colored plant foods you include in your diet, the more antioxidants you consume. Even beets contain beta-carotene, which is also found in carrots, spinach and broccoli. Eating more antioxidants may help reduce the risk of certain cancers.

Beetroot’s potassium content may also play an important role in blood pressure regulation. While small amounts of sodium are necessary, too much sodium in the diet can increase blood pressure over time. Potassium helps eliminate excess sodium from the blood through urine.

How drinking beetroot juice can help reduce high blood pressure

In another study, anemic Indian girls who drank beetroot juice saw increased levels of hemoglobin, which carries oxygen throughout the body. A person with anemiahas low red blood cells or hemoglobin levels.

Still, more research is needed to understand how supplementary forms of beetroot may affect human health.

Beetroot has a reputation throughout history as an aphrodisiac. It is said that Aphrodite, the ancient Greek goddess of love, ate beetroots to make herself more attractive.

While eating beetroot alone won’t make you more attractive, this myth may actually stem from the nutrients in beets that can make you feel better and potentially increase your sexual desire. These include betaine, boron, and tryptophan.

What types of beets can be eaten?

The beets we know today in the United States are one of four types of beets known as garden beets. Other types of sugar beets include sugar beets and sugar beets used for livestock.

But the variety doesn't stop there. The National Gardening Association has identified five subtypes of garden beetroot, including:

  • Detroit Crimson These have the deepest red roots of all garden beets
  • Formanova grows in a cylindrical shape
  • Lutz Green Leaf This variety is the largest of all types of garden beets
  • Chioggia These beets have red and white stripes on their roots
  • Golden beetroot is carrot color

Is beetroot good for weight loss?

Some people tout beet supplements as performance enhancers, and increased exercise can play a role in your overall weight loss efforts. But know that beet supplements alone won't help you lose weight. Central to the potential weight-loss benefits of vegetables is the plant's nutrient density: It provides fiber, antioxidants, and vitamins while still being low in calories.

Can diabetics eat beetroot?

Can beetroot "detoxify" the body? If so, how does that work?

Due to the nutritional value of beets, there are rumors online that they can detoxify the liver. This statement is often associated with beet juice because it is easy to drink in large amounts during a detox.

The idea with detoxification, so to speak, and other types of liver detoxification methods is to flush out built-up toxins and refresh your liver. Some say detoxing can help your liver function more efficiently. But the truth is, there's no clinical evidence that beetroot detoxifies the body—and there's not enough solid evidence that any type of liver detox works well.

Tips for selecting and storing beets

The best whole beetroot roots are free of bruises and blemishes. If you're looking for beets with a more tender texture, choose medium-sized beets. Larger versions tend to be sturdier and may also be more difficult to cut.

Whether you plan to eat beets or not, make sure you buy them with the greens still attached - they indicate the freshness of the plant and help keep the roots fresh.

You can add beets to your favorite smoothies for an extra kick).

Consider these recipes to make your own beets:

  • Strawberry and Beet Salad
  • Vegan packaged hummus

Beetroot has been popular in the athletic world as a possible way to help improve athletic performance. Beet juice and beetroot supplements are said to help dilate your blood vessels while you exercise, delivering more nutrients and oxygen to your muscles so you can exercise for longer. However, the jury is still out on whether this actually helps relieve muscle fatigue. Beets are more likely to help people who exercise recreationally rather than bodybuilders or other high-endurance athletes. Still, many athletes, including Olympians, swear by it.

Food manufacturers also use beets to add a red color to some foods. This does not mean that the food in question is healthier. It's important to look at foods holistically and read ingredient labels carefully.
