You can make your own yogurt, using cow's milk or a non-dairy alternative like soy, as it's rich in protein and probiotics (good bacteria that keep your gut healthy). In light of this, we might think that a low-fat or fat-free yogurt would be even healthier. However, be careful. Fruity varieties often contain more sugar than full-fat yogurts! The problem with plain or Greek low-fat yogurt is that it sometimes has added sugar. When one is removed, the other is usually added to enhance the flavor. Be sure to always check the ingredient list and nutritional information for sneaky added sugars if something is advertised as low fat. Depending on their form, they may be listed as sugar, sugar syrup, honey or glucose - if in doubt, consult the traffic light system. Your "healthy" breakfast yogurt is likely to contain added sugars if it's red. Aside from that, low-fat sugar-free yogurt isn't very calorie-dense and won't sustain you for long. Add fruit of your choice and oats or nuts to make a healthy breakfast that will fill you up.
