Is seaweed a vegetable?

Seaweed is technically a type of algae. Algae are a type of plant-like organism usually found in water. Unlike land plants, algae do not have root systems, flowers, or leaves.

This means that seaweed aren’t really vegetables like land vegetables. However, many people use seaweed as a vegetable, and refer to it as a ‘sea vegetable’.

The truth is, it doesn’t matter if it’s technically a vegetable or not, as long as you enjoy it!

How much seaweed should I use a day?

There is no right or wrong answer as to how much seaweed you ‘should’ eat per day. Seaweed is a highly nutritious natural food that you can incorporate in your diet regularly as part of healthy eating.

One of the many nutrients seaweed contains iodine. According to the Australia Recommended Daily Intake (RDI), adult both men and women require 150mcg per day. That translates to 3-4g of alg Original. As alg is a dehydrated product, while 3-4g appears to be small, you are actually eating 30-40g hydrated seaweed!

If you’re new to seaweed, it’s perfectly ok to start up with a small amount, and work up to daily consumption.

What are the different types of seaweed?

There are dozens of different types of seaweed that you can munch on! The main classes are red algae, green algae and brown algae.

However, the most common seaweeds for consumption include kombu, nori, dulse, and of course wakame. Kombu and wakame are types of kelp, a class of brown algae. Nori and dulse are red algae.

Interestingly, chlorella is classified as a type of edible seaweed – but it’s far less tasty than wakame.

How long does Alg products last?

Our Alg Australian range is a dried product which mean it naturally have a long shelf life. Except Alg Bonito Sesame which has a 12-month shelf life, all of our products can last 18-24 months or longer if stored appropriately.

What kind of seaweed do we use in Alg?

Alg seaweed are Tasmanian locally foraged, sustainably hand harvested wakame. The principle product, Undaria pinnatifida, is an introduced invasive seaweed to Tasmania. Undaria pinnatifida (also known as Wakame) was first identified in Tasmania in 1988 and has since been reported from St Helens (NE coast) to Dover (S coast). It was thought to have been originally introduced into Tasmania via the ballast water of ships trading from Asia.

How do you use Alg?

Alg can be used in both savory and sweet dishes. As the seaweed is naturally slightly salty, by just adding a teaspoon into the dish adds extra umami flavor and extra nutrition to your meal. From sprinkling it on salads, to smoked salmon on crackers, to polenta chips or chocolate. The Alg range is very versatile and should be in everyone’s pantry.

Can you eat too much seaweed?

Loving your daily seaweed fix? Most likely, you’re in the clear.

However, if your diet isn’t balanced nutritionally, you can over-consume seaweed. There are rare reports of very high intakes of seaweed products impacting on thyroid health in people with underlying issues.

Not to worry – this is very uncommon, and tends to occur more with large amounts of uncooked kombu.

But if you’re worried about your consumption, consult your friendly health practitioner for guidance.
