Milk Substitutes.
Rice Milk
Rice milk has a higher concentration of carbohydrates and contains less calcium and protein. It also has no fat, cholesterol or lactose. Rice milk is a good alternative to cow's milk because very few people are allergic to it compared to cow’s milk. Kokkoh is a kind of rice milk from Thailand that I have actually tried before. It can be recommended for children as it's easily digestible and hardly ever causes any allergies. Rice milk is a mixture of water and various cereals so is very high in protein. In Thailand where I now reside, Kokkoh is commonly consumed for breakfast and also shares the same name with a town in Thailand.
Almond Milk or other Nut Milk.
Almond milk is of course made from ground almonds. It contains no cholesterol fat and is lactose free. It has very little protein however. I've never tasted this milk before. It's probably easy to make though, just blending ground almonds with water and a sweetener as you like.
Coconut Milk
Coconut milk is very high in saturated fat, low in protein however.
I've mostly ever used coconut milk when cooking as my wife uses it for her delicious Tom Yam Gunk and Chicken with Green Curry.
Soya Milk
Soya or Soy milk is made from Soya beans that come from China. It consists of the same amount of protein as cow’s milk and is nutritionally close. Soya Milk has little saturated fat and no cholesterol. It's a healthy alternative to cow’s milk because it's a great source of vitamin E, it's safe for people with lactose intolerance or milk allergy.
Evaporated Milk
Evaporated milk is simply fresh milk that is heated to remove a proportion of its water. The evaporation process of water makes the milk richer and creamier with a higher amount of protein and calcium.
Other Alternatives.
Sunflower Milk
Goats Milk
I'll will be deciding very soon on the milk substitute that I'll give a trial run. Read about my choice here.
