Apple cider vinegar is a great addition to your diet as it can be used instead of red wine vinegar or balsamic. You can use it to dress your salads with olive oil.  Apple cider vinegar is great for keeping blood sugar stable.  I love sour flavors like lemon and vinegar so I add a splash to my water and it really quenches your thirst! It also curbs your appetite and makes drinking water more appealing!
Cinnamon is also great for stabilizing blood sugar levels so add it to your yogurt, cereal, coffee, oatmeal etc. It tastes great and is good for you!
