Plant-based dairy alternatives are on the third level of the vegan food pyramid. You should have 1-3 servings a day, a serving consisting of 100-200 g of plant-based milk or yoghurt. This list here offers just a few suggestions to pick from.
As you can see, the list also contains vegan cheese alternatives. These are okay, too, however, preferably pick dairy alternatives with calcium supplements (that also goes for any milk or yoghurt alternative). Many vegan cheeses, apart from not containing calcium, consist only of isolated fat, starch and aromas, without any relevant micronutrients whatsoever, nor any protein! Yeast products are a good alternative with cheesy taste and nutrients.
Also, try to prefer unsweetened products and rather add fruit and spices yourself. Apart from that, consider that, if you have difficulties eating enough legumes or other protein sources, you should prefer dairy alternatives that are high in protein – meaning, rather those based on legumes than on cereals.
