Think, you would, that two brands of yogurt that are both 0% milk fat, that they would taste the same. But oh no, they taste very different. We usually buy Yoplait Source Zero yogurt, but there was a sale at our local Chinese store on Astro Original with 0% m.f., so I bought some. It turns out the Astro is terribly sweet, and for good reason: at 12 g of sugar, or 1 tablespoon, it has 3 times the sugar than Source Zero. We won’t be fooled again by Astro Original.

The Astro Original is a new packaging of their Original 4% mf product, and it was the first time I have seen it. The green packaging makes it unique on the shelf. This is the first and last time I buy Astro fruit yogurt for her, as our family does not like overly sweet edibles. As is the trend now, there are 4 flavours: strawberry, peach, raspberry and blueberry, and she dislikes the blueberry. It is hard to see the flavour when it is in my fridge, as the graphic for the fruit is very small, and the flavour is in uppercase in smallish letters. The usability of the labelling is not good. I usually buy Astro Original yogurt in plain, so there should not be too much sugar.
Astro Original yogurt 0% mf has 12g of sugar, or 1 tablespoon, per 100g cup. That is 12% of its contents as sugar, and about 1/4th or 25% of your recommended daily sugar (4 tablespoons, 10% of your caloric intake), according to the World Health Organization. The WHO has now revised sugar consumption down to 5% of caloric intake. Annoyingly Canada has no recommended maximum sugar intake level. They need to get off their duff and do their jobs.

Three cups of 100g Astro Original yogurt has 36g of sugar, the same as a 12-ounce can of Coca-Cola has 35 grams of sugar. For the small size of these 100g cups that is a lot of sugar.
The Yoplait Source Zero yogurt 0%mf, on the other hand, has only 4g of sugar or 33% of the equivalent sized Astro Original yogurt 0%mf. This is substantially less.
There is sweet and then there is excessively sweet. I do not recommend the Astro Original because it gives you so many more empty calories from sugar.

Astro Original yogurt 0%mf (left) vs Yoplait Source Zero yogurt 0%mf (right), nutritional information, side by side. The Astro contains 12g of sugar, a tablespoon, vs the Yoplait Source Zero’s 4g. That is a sizeable difference. For your health, choose the Yoplait Source Zero yogurt. Scan by Don Tai.
This reminds me that I’ve seen research that states that zero or low fat products can taste bland, so food manufacturers make up for this by adding in a lot more sugar. I believe that this is what Astro has done.
