The Dietitian's Health Tip ...

Eat healthy, natural, organic, wild food. 

My Dietitian Says... 

Regular Hand Washing...

- Always wash your hands before touching food.

- When Dining Out... It's a good idea to wash your hands before eating. Hand washing is key to preventing the transmission of disease. Germs travel from surfaces that you have touched to the food that you eat. Washing your hands is a simple action that has wonderful health benefits. While in the lavatory, use a clean paper towel to turn off the faucet and to open the door when leaving. These surfaces are often forgotten by the cleaning crew, and may harbor disease causing organisms - not something that you want to bring to the table with you!

Food Intolerances and Allergies

We determine foods that you react to and help you to make a healthy eating plan that will keep you healthy for life.

What is a Registered Dietitian?

- A registered dietitian (R.D.N. or R.D.) is the medical provider who is licensed by the state to use medical nutrition therapy in the prevention and treatment of obesity, diabetes, kidney disease, heart disease, and many other conditions and diseases. 

- A registered dietitian will help you to create a healthy and delicious eating and lifestyle plan - not a fad diet that you cannot comply with for the long term - but a healthy plan that you can enjoy for the rest of your life.

- Everyone should have a registered dietitian on their team of regular health care providers. You should visit your registered dietitian at least once a year for a "nutrition and lifestyle check-up". During these visits your registered dietitian will help you to make your eating, lifestyle, and physical activity plan a healthy one.

- Creating a healthy eating plan, with the help of a registered dietitian, helps to prevent and treat many common conditions and diseases that are affected by nutrition, lifestyle, and physical activity choices, and helps you live a long, vigorous, independent, and healthy life. 

- Healthy nutrition is good medicine, and when paired with healthy lifestyle habits, regular physical activity, and stress management, it forms the foundation upon which much of health and medicine rest.

- Form a working relationship with a registered dietitian.  It's one of the best decisions that you will ever make!
