how to detect the presence of Iodine in table salt ?

how to detect the presence of Iodine in table salt ?
Can I use some kind of paper test strips ?
thanks

As the previous answer says, you could add silver nitrate solution, and then steadily add ammonia. If an iodide is present there will remain (after the white precipitate of silver chloride has dissolved) a small amount of yellow silver iodide.

Alternatively, you could add a few drops of concentrated sulphuric acid to the solid. Any iodide present will be oxidised to iodine and, because the reaction is exothermic, purple iodine vapour will be produced along with HCl gas from the chloride ions. Take care how you do this, use a small quantity only. But even at low concentrations the colour of iodine vapour ought to be clearly visible.

Edit...
The link in 'Robert D's answer is certainly a straightforward test.
If this is being done at school/college (or as part of a theoretical planned procedure) then all the tests mentioned in the various posts would be valid answers.
If this is being done at home (i.e. without having access to silver nitrate or sulphuric acid or hydrogen peroxide), then adding a few drops of household bleach (sodium chlorate(I) solution) - take the usual precautions you would when using bleach - would be good enough to oxidise the iodide ions to iodine. This would produce a visible brown/yellow colouration to the solution if iodine was present: adding a little starch (you might have some at home for the ironing!) would then give the intense dark-blue of the iodine-starch complex.

Type 2 Diabetes: Tips for a summer of Healthy Cookouts

We are all advised to live healthier lifestyles? Eat more healthily, lose weight, exercise more, stop smoking? And so on. For people who have Type 2 diabetes this advice is an important part of the management of diabetic diet menu. You may be surprised to learn that you actually have the potential to reduce the harmful effects of diabetes, purely by making some changes to your lifestyle.

Every person who has diabetes has difficult problems, which comes from the various degrees of complications that they may be dealing with. Because of the differences, some are able to eat a few more carbs than others. However, the types of foods that you should be avoiding, and those diabetic meals that you should be eating, is going to be the same for every person who is dealing with diabetes.

We focus on the role of diabetic diet and exercise in the management of Type 2 diabetes. In particular, we will take a look at the way in which diet and exercise can improve:

* Blood glucose levels

* Blood fats

* Blood pressure

Blood glucose levels: Blood glucose levels are mainly kept in check by insulin syringes and needles. Type 2 diabetes usually occurs as the result of a combination of problems with insulin activity (insulin resistance) and insulin secretion. Diet and exercise can help to combat both of these problems.

Blood fats: Many people with Type 2 diabetes have unhealthy levels of blood fats? This is commonly referred to as an unhealthy? Lipid profile? Too much of the wrong types of fat in the blood increase the risk of heart disease and circulation problems. Blood fats are mainly kept in check by body fat analyzer. Another important aim of diet and exercise in the management of your diabetes will therefore be to help keep your blood lipid levels normal.

Blood pressure: Type 2 diabetes is often accompanied by high blood pressure and this increases the risk of diabetic eye and kidney damage, as well as heart disease and circulation problems. Blood fats are mainly kept in check by automatic blood pressure monitor. Regular exercise, eating a low-fat and low-salt diet, and reducing alcohol intake can all help to lower blood pressure.

Nearly everyone knows about the dietary risks of summertime cookouts; the menu tends to be loaded with items that are high in fat, high in calories, and full of grease. # However, there are healthy alternatives that you can include in your next cookout to ensure that your diabetic diet plan stays tasty, but won't ruin your dietary goals. Here are some healthy food choices to add to your next cookout:

Grill Veggies: Cut veggies, such as peppers and onions, to roughly the diameter of a silver dollar. Dust them with a light layer of extra virgin olive oil and season to taste. Always prefer Low Fat Salad Recipes for diabetes.

Wrap the veggies tinfoil and throw the package on a grill. Cook the veggies alongside your hotdogs and hamburgers for about 20 minutes, or until the veggies are tender and hot.

Mayo-free Potato Salad: Not all potato salads diabetic recipes require mayonnaise. In fact, without the mayo, potato salads can be quite healthy and incorporate not only a healthy dose of carbohydrates, but also onions, celery, oils, and dairy. Check online for mayo-free potato salad recipes that suit your taste buds.

Full-Fruit Popsicles or Ices: Instead of offering ice cream or another high fat, high sugar dessert, plan ahead and make your own full-fruit popsicles or ices. Simply freeze any flavor of 100% fruit juice in an appropriately sized and shaped container, add small fruit chunks, and serve. You can find Popsicle trays in just about any grocery store.

Limit the Alcohol: Most people enjoy having a summertime beverage, such as a margarita, daiquiri, or even a simple beer during a cookout.
However, many fancy drinks are loaded with sugar that is not healthy for Diabetics.

While a splurge may not hurt every now and then (as long as you monitor your blood sugar level), it is always a good idea to have low-sugar alternatives such as sugar free candy and low fat desserts. One of the best low-sugar alcohol beverages is rum and diet coke.

The Right Melons: Watermelons are classic cookout favorites. However, watermelons are notorious for having loads of sugar and calories in them.

In fact, one slice can pack as much as 80 calories. Instead of serving watermelon wedges at your next cookout, opt instead for honeydew or cantaloupe.
