By now you have probably heard all about a gluten free diet. This means excluding gluten, a protein that is found in grains such as bread, pasta and cereal from your diet. This is a specialized diet for people who have celiac disease or who are allergic to gluten or have a gluten intolerance. Since the word “diet” is synonymous with losing weight, some people mistakenly think that it’s a weight-loss plan, but it isn’t intended to be that. A gluten-free diet excludes many common dietary staples so you should follow it under the supervision of a doctor or dietitian.
When it comes to your gut and your kid's guts you have also probably heard a lot about Probiotics. Probiotics promote good digestion, strengthen your immune system and protect against disease-causing “bad” bacteria. They are also handy for treating diarrhea and urinary tract infections. Certain
Lactobacillus and Bifidobacterium strains may help reduce the duration and severity of a cold. You should consume probiotics when you take antibiotics; they will replace the good bacteria that the antibiotics have killed. There are many different strains of probiotics and each one offers a different health benefit.
Lactobacillus acidophilus and Bifidobacterium bifidum, for example, may help boost your immunity. There are other strains and combinations that may help prevent colds and urinary tract infections, and help with lactose intolerance. Talk to a health-care professional to determine which type will best meet your needs. Probiotics are found in yogurts and fermented products.
By now you have also probably heard about Stevia. natural sweetener that’s 200 to 300 times sweeter than sugar and extracted from the stevia shrub, which is native to Paraguay. Stevia sweetens like sugar, but has no calories. Stevia has been safely used as a sweetener for hundreds of years in South America, but there aren’t any clinical studies on its safety.
Adults are best to stick to no more than 280 milligrams a day of stevia leaf powder. Liquid and spoonable stevia powders are available in health food stores. In Canada, stevia is not permitted as 
a food additive for widespread use because of the lack of research. It can be found in some natural health products that have a natural product number on them. This means they are government regulated and must list a dosage amount on the package.
Stay away from any nutrition trend that is not government regulated. It is quite simply bad for your health.
