Is Kelp Vegan? Can Vegans Eat Kelp?

Kelp is vegan and is basically a sea vegetable.

Kelp is a brown algae seaweed that’s packed with iodine, fiber, and magnesium. It provides great health benefits. However, you have to take it in moderation due to its high iodine content, which can cause iodine toxicity.

In this article, you will learn more about kelp, and how to make it part of your diet in the healthiest way possible.

What Is Kelp?

Close to the shore, in the shallow waters, you will find the kelp forest that feeds thousands of sea animals. A carbohydrate derived from kelp called alginate is used as a food thickener in ice cream, salad dressings, jellies, cakes, and even in toothpaste or shampoo.

Kelp grows in a dense group just like a forest. Due to its sturdy anchor on the ocean floor, it’s considered a sea tree, where many sea mammals seek shelter. The kelp canopies typically grow in cool, nutrient-rich open waters and depend on sunlight for growth.

Because of their sunlight dependence, kelp can’t grow any deeper than 131 feet. According to National Oceanic and Atmospheric Administration (NOAA), kelp gets dislodged during weather changes such as El Niño. This leaves a torn forest that grows again in the spring.

Other species of kelp like kombu are also a staple of many East Asian food cultures. Kombu is used to flavor different stews and broths, and as a flavored garnish for various dishes.

How Healthy Is Kelp?

As a great source of iodine, minerals, calcium, antioxidants, among others, kelp has been a part of many Asian diets. Not only that it became a staple in Asian cuisine, but it has also been a popular ingredient in other dishes throughout the world.

Apart from alginate that’s used as a food thickener, you can actually eat kelp in any form – cooked, raw, powdered, or through supplements. According to the National Institutes of Health (NIH), kelp is one of the great sources of iodine, a trace element that’s essential to thyroid hormone production.

It’s also a big factor in the development of the skeletal and central nervous systems in infants and fetuses. Kelp also helps boost energy levels and brain functions. However, too much iodine intake can pose risks of thyroid problems.

According to health experts, the recommended dietary allowances (RDA) for healthy adults should only be 150 mcg of iodine. Infants to 12 months old should get at least 110 to 130 mcg while toddlers and teens should take up 120 mcg. Pregnant and lactating women should get more intake of between 220 and 290 mcg of iodine per day.

Kelp also provides more vitamins and minerals such as:

  • Vitamin K1: 55% of the daily value (DV)
  • Folate: 45% of the DV
  • Magnesium: 29% of the DV
  • Iron: 16% of the DV
  • Vitamin A: 13% of the DV
  • Pantothenic acid: 13% of the DV
  • Calcium: 13% of the DV

Sea vegetables, including kelp, may help slow down or reduce the risk of breast and colorectal cancer, according to certain studies. This is due to the compounds found in the seaweed extract, which have anticancer agents.

Because kelp is a great source of antioxidants, this can help prevent or lower the risk of several chronic diseases such as cardiovascular problems and stress. Kelp is also low in fat and calories, which may help weight loss in obese, especially when paired with pomegranate oil.

Its natural fiber called alginate, which is used as a food thickener, is said to have the capabilities to stop fat absorption. Several studies also suggest that kelp can help reduce blood sugar levels, which benefits those who are suffering from type 2 diabetes.
