Castevia 1:1


Castevia 1:1 is a zero-calorie product, with a taste very similar to sugar and without an after-taste, so it’s your best option if you want to buy stevia online.

Stevia is not a recently discovered sweetener but many studies have already made it clear that it is the most natural and healthy sweetener that is currently available on the market. Much of its success is due to its lack of calories and because it is a sweetener with a zero glycemic index, that is, it is totally suitable for diabetics.

However, there is still much ignorance about the origin and the properties of this very sweet compound.

Before buying Stevia online: What exactly is Stevia and how is it obtained?

Stevia is a shrub from the Paraguayan cordillera of Amambay that has been used as a sweetener in Brazil and Paraguay for many years. It has been used in countries such as Japan for almost 40 years but its approval as an additive was delayed in the United States and Europe until 2008 and 2011 respectively. Specifically between those years, addition of Stevia to a large number of products has increased 400% and although it seems now to be a novel sweetener, in reality it has a long history behind it.

What is certain is that the high levels of obesity and diabetes in the world population have served to increase our concerns about food. In fact, there are already many people who have started following healthy and balanced diets that exclude products with too much processing, fats, pre-cooked foods and all additives that pose a long-term risk to their health.

Regarding the process of obtaining Stevia, it consists of soaking the dry leaves of the plant and then separating the best sweet compounds (steviol glycosides). Nothing could be more natural!

What does Castevia 1:1 mean?

Very simple. 1 spoonful of Castevia 1:1 is equivalent to 1 spoonful of sugar.

What makes us different?

Without doubt, our crystallisation process.

Because of our manufacturing process, both ingredients crystallise in the same crystal, giving the product a natural taste and 100% homogeneity, without needing to use artificial aromas or masking the flavour.

Benefits of Stevia

Stevia has a host of positive properties that derive from the high phytonutrient content and volatile oils. It also contains iron, manganese and cobalt. This makes the sweetener into a product that is antioxidant, antimycotic, diuretic, vasodilatory, hypotensive and prevents tooth decay. Yes, you read correctly. In contrast to sugar, consuming Stevia not only does not harm the teeth but is also beneficial for keeping them healthy.

Apart from all these positive benefits, Stevia does not contain caffeine or any type of saturated fat. So buying Stevia online is a very smart decision.

Stevia, leaving aside it natural origin and beneficial properties for the body is not harmful for people with diabetes or obesity because of its zero glycemic index. This is the reason for a large part of its success, because everyone who could not sweeten their lives can do so now with Castevia 1:1.

Specifically, there are many benefits of consuming our Castevia 1:1:

  • Natural product, 0 calories
  • A taste very similar to sugar
  • Suitable for diabetics
  • No after-taste
  • No effect on the level of sugar in the blood (zero glycemic index)
  • Healthy for your teeth

What’s the difference between Castevia 1:1 from Castevia 1:8?

Castevia 1:8 is equally healthy and beneficial for health as Castevia 1:1, but has a small disadvantage when being used in that it has such an intense sweetness that it does not correspond to the sugar that we normally use; that is, one spoonful of Castevia 1:8 is equivalent to 2 spoonfuls of white sugar.

So that when following a recipe with specific requirements for home-made pastries or any other dish, this could become a disadvantage. Thus Castevia 1:1, with a more similar taste to that of sugar and fully equivalent to sugar is more practical: one spoonful of Castevia 1:1 is equivalent to one spoonful of sugar. In this way, you don’t have to be making calculations when following recipes because you do exactly the same as you would with sugar. But the result is much healthier, of course!

Any of the two varieties of Castevia available from NaturalCastelló have a unique composition and flavour that ensure you won’t miss sugar at any time. Therefore purchasing stevia online from our website is a very smart option. So, if there is a sweetener with the same flavour as sugar but much healthier, why not start to include it in your diet?
