In general, the best advice to give a landlord is to repair a problem with a rental property as soon as possible. Heating and plumbing problems, because of their unique nature, should be handled within 24 hours of learning of the issue.
Know your portions. Following a low sugar diet requires some diligence in knowing how much you should be eating. In general, most people should consume 2 fruits (or 2 cups) and at least 3 cups of veggies per day. On average 1 serving of fruit contains 15 grams of sugar.
According to the ADA, eating fruit results in better blood sugar control than eating the same amount of calories and sugar from foods like cookies and cake. So when you really want something sweet, choose fruit instead. The ADA also recommends 2 to 3 servings per day of low-fat dairy.
