Diet and Lifestyle Trends of 2019

With so many different diets available, choosing one that works best for your body and lifestyle can feel overwhelming. When considering a diet, be sure to research its benefits and impact so you can best support your long-term goals.

Understanding the Types of Diets

Clean Eating

Healthy eating diets focus on incorporating more whole foods, such as fruits, vegetables, whole grains, healthy fats and lean proteins into your diet and limiting processed or packaged foods.

Disease Management

If you suffer from a chronic disease, your doctor has likely recommended that you work with a dietician to develop a healthy eating plan to help manage the symptoms and risk factors associated with it.

Restrictive Diet

Restrictive diets limit or eliminate the consumption of specific foods.

Weight Loss

Losing weight through diet and exercise is the main goal of weight loss diets. Many weight loss diets aim to help you lose excess weight, but may not emphasize making changes to your daily routine.

Main Foods You Avoid: None

A gluten-free diet excludes the protein gluten. This protein is found in the grains barley, rye and wheat.

Type of Diet: Restrictive, Disease management

Why You Might Consider This Diet: Following a gluten-free diet is essential to managing celiac disease. Celiac disease is a chronic autoimmune disease where the ingestion of gluten leads to damage of the small intestines. The diet is also followed by individuals with wheat allergies and/or food sensitivities. *Please consult your physician if you have celiac disease and/or have wheat or gluten allergies and/or sensitivities.

Main Foods You Consume: Fruits and vegetables, eggs, lean meats, fish and poultry, beans, seeds and nuts, gluten-free grains (Flax, Quinoa, Rice, Teff)

Main Foods You Avoid: Barely, Oats (in some cases), Rye, Triticale (a cross between rye and wheat), Wheat, Most beer

How It Impacts Your Body: For individuals with celiac disease, following a strict gluten-free diet allows the small intestine to heal, causing symptoms to resolve. In children, digestive symptoms are more common, where adults are more likely to experience symptoms such as fatigue, depression or anxiety and missed menstrual periods. Some individuals with the disease may have no symptoms. There is little evidence that there are any health benefits to following a gluten-free diet for individuals without celiac disease or gluten sensitivity.
