Seaweed and mushrooms are often considered vegetables, especially in culinary contexts. However, from a botanical perspective, they are not plants or animals. Seaweed is a type of marine algae, specifically a protist, while mushrooms are fungi. The word vegetable is derived from the Latin word vegetabilis, which means animating, enlivening, vivifying. While the definition has evolved over time, it generally refers to plants cultivated for food. As such, seaweed and mushrooms are not technically vegetables, but they are still highly nutritious and can be used in similar ways to traditional vegetables in dishes like salads and soups.

What You'll Learn
Seaweed is a vegetable, sort of
Seaweed has long been a staple ingredient in Asian dishes and is known for its nutritional value. It is often used as a substitute for vegetables in dishes, such as in seaweed salads. But is it a vegetable?
The word "vegetable" is derived from the Latin word "vegetabilis", which means "animating, enlivening, vivifying". Vegetabilis was later used by the French to describe "all non-animal life". In the late 18th century, the word vegetable was used more specifically to describe "a plant cultivated for food, an edible herb or root".
From a botanical perspective, seaweeds are not classified as vegetables. A vegetable is a plant or part of a plant that is used as food and grows on land. Vegetables belong to the plant kingdom, and can be classified into different categories based on their parts, such as leaves, roots, stems, flowers, and seeds. Most seaweeds are not plants. They are classified into three groups based on color: red (Rhodophytes), green (Chlorophyta), and brown (Phaeophytes). Green seaweeds such as sea lettuce are part of the plant kingdom, but the other two groups are not. Brown seaweeds are in the kingdom Protista, and red seaweeds are currently without a kingdom classification.
Despite not being a true vegetable or a land-based plant, seaweeds are still a highly nutritious food that is rich in vitamins, minerals, antioxidants, and omega-3 and omega-6 fatty acids. For this reason, from a culinary perspective, seaweed is often considered a vegetable. Seaweed is used in a similar way to many vegetables, such as in salads and soups. Seaweed is also high in many of the same vitamins and minerals as vegetables, such as vitamin C, vitamin K, and potassium.
In summary, while seaweed is not technically a vegetable according to botanical definitions, it is often referred to and used as a vegetable in culinary contexts due to its nutritional profile and versatility in cooking.

Seaweed and mushrooms are not plants or animals
Seaweed and mushrooms are often considered vegetables in culinary contexts. Seaweed, for example, is commonly used in salads and soups, much like other vegetables. However, from a botanical perspective, neither seaweeds nor mushrooms are classified as plants or animals.
Seaweeds are classified into three groups based on colour: red (Rhodophytes), green (Chlorophyta), and brown (Phaeophytes). While green seaweeds like sea lettuce are part of the plant kingdom, the other two groups are not. Brown seaweeds such as kelp are classified as Protista, while red seaweeds like Irish moss are currently without a kingdom. Despite this, seaweeds are often referred to as \"sea vegetables\" and are commonly eaten in Asian countries such as Japan, Korea, and China. They are also increasingly used in cuisines worldwide due to their nutritional value and health benefits.
Mushrooms, on the other hand, belong to the kingdom of fungi, which are not plants. Mushrooms grow out of the soil like plants, but they do not have flowers or seeds. Instead, they produce spores. Mushrooms are also high in nutritional value, containing vitamins, minerals, and antioxidants.
The definition of a vegetable has evolved over time. The French adopted the term "vegetable" in the mid-15th century to describe \"all non-animal life.\" Later, in the late 18th century, the definition narrowed to refer specifically to \"a plant cultivated for food, an edible herb or root.\" This shift in definition has contributed to the confusion around classifying seaweed and mushrooms as vegetables.
In summary, while seaweed and mushrooms may be referred to as vegetables in culinary contexts due to their similar uses and nutritional profiles, they are not botanically classified as plants or animals. The evolving definition of a "vegetable" has further complicated the classification of these organisms.

Seaweed is a type of marine algae
Seaweed is commonly referred to as a sea vegetable, but it is not a true vegetable or a land-based plant. It is a type of marine algae that grows along rocky shorelines worldwide and is commonly consumed in Asian countries such as Japan, Korea, and China. Seaweed is classified into three groups based on colour: red (Rhodophytes), green (Chlorophyta), and brown (Phaeophytes). While green seaweeds like sea lettuce are part of the plant kingdom, brown seaweeds such as kelp and rockweed belong to the kingdom Protista, and red seaweeds like dulse and Irish moss do not fit into any current scientific definitions of plant kingdoms.
Despite not being a plant, seaweed is often categorised as a vegetable in culinary contexts due to its similar usage to vegetables in dishes like salads and soups. It is also highly nutritious, containing vitamins, minerals, antioxidants, and fibre. Seaweed is especially rich in iodine, which is essential for thyroid function, and tyrosine, an amino acid that supports the thyroid gland.
Seaweed differs from vegetables in that it does not have "true roots", stems, or leaves. Instead, it is a colony of algae that creates its own food through photosynthesis. While the definition of a vegetable has traditionally been associated with plants cultivated for food, the term has evolved to encompass a broader range of edible organisms, contributing to the ambiguity in classifying seaweed.
In summary, while seaweed may be referred to as a sea vegetable, it is primarily a type of marine algae that falls outside the traditional definition of a vegetable. Its classification as a vegetable is influenced by its culinary applications and nutritional value rather than its botanical origins.

Mushrooms and seaweed are a perfect umami combo
Seaweed and mushrooms are a perfect combination for creating umami flavours. Umami is one of the five basic tastes, along with sweetness, sourness, bitterness, and saltiness. It is often described as savouriness and is considered deeply satisfying. Seaweed and mushrooms are both sources of umami, and when combined, they create a rich, hearty flavour that is more than the sum of its parts.
Seaweeds are not plants or animals, and from a botanical perspective, they are not classified as vegetables. However, they are often considered vegetables in a culinary context, as they are used similarly to vegetables in dishes like salads and soups. Seaweed is also highly nutritious, containing vitamins, minerals, and antioxidants, as well as being a good source of iodine.
Mushrooms, similarly, are not plants or animals, and they are classified as fungi. They are a popular ingredient, valued for their hearty, umami flavour and versatility in dishes.
Combining these two ingredients creates a synergy of flavours and textures. The slight saltiness of seaweed enhances the savoury notes of mushrooms, creating a flavour explosion. One simple way to enjoy this combination is by sautéing mushrooms with butter and seasoning them with seaweed flakes. This can be served as a side dish or used as a base for more complex recipes, such as a mushroom and seaweed broth or a savoury pastry.
For a nourishing and flavourful broth, you can sauté mushrooms and a variety of vegetables with sesame oil, add hot water, and simmer. The seaweed will soften, thickening the broth and adding a delicate salty element. The broth can be served with rice or noodles or drunk straight from a mug, providing a hydrating and nutritious meal. Alternatively, you can spread the mushroom and seaweed combo on a sheet of puff pastry and bake it in the oven for a quick and tasty weeknight meal or weekend lunch.

Seaweed is often referred to as a superfood due to its high nutritional value and is a great way to add variety to meals.
Mushrooms, like seaweed, are also not plants or animals. Genetically, humans are more closely related to mushrooms (fungi) than brown seaweeds. Mushrooms are nutritious and flavourful, and when combined with seaweed, create a delicious umami taste experience.
A simple way to incorporate seaweed and mushrooms into your diet is through a mushroom and seaweed broth. This recipe includes a variety of vegetables, such as ginger, and is flavoured with sesame oil and sesame seeds. The seaweed adds a delicate salty element to the broth, while the mushrooms provide a hearty flavour and texture.
