LIFESTYLE THERAPY

• "Cardiometabolic death" refers to death from heart disease, stroke, & T2D

• ~ half of all cardiometabolic deaths (ie, 318,656 of 702,308 such deaths) in US → associated with suboptimal intakes "of vegetables, fruits, nuts, seeds, & omega-3 fatty acids”

Micha et al. JAMA Mar 2017

Nutritionists / clinicians are concerned about blood glucose levels, obesity, diabetes, & other health implications they believe → “Sugar is the New Tobacco”

Sodium is another long-time concern, prevalent in processed foods

Pan A et al. Arch Int Med 2012;172:555-63

Follow-up 37,698 men + 83,644 women, health professionals, for up to 28 years

Participants did not have cardiovascular disease or cancer at baseline

→ Consumption of red meat ↑ risk for cardiovascular, cancer, and total mortality

• Medical nutrition therapy (MNT) has its greatest impact when a person is first diagnosed with diabetes

• MNT, the nutrition-based treatment provided by a registered dietitian nutritionist, includes a nutrition diagnosis as well as therapeutic and counselling services to help manage diabetes

Strategies for people with Diabetes

• Portion control should be recommended for weight loss & maintenance

• Carbo-containing food & beverages + endogenous insulin production are the greatest determinants of post-meal glucose level;

• It is important to know what foods contain carbohydrates eg. Starchy vegies, whole grain, fruit, milk & milk products, & sugar

• When choosing carbo-containing foods – choose nutrient-dense, high fiber foods whenever possible ; instead of processed food with added sodium, fat & sugars. Nutrient-dense foods & beverages provide vitamins, minerals & other healthful substances with fewer calories

• Avoid sucrose-sweetened beverages (SSBs)

AB Evert et al. Nutrition Therapy Recommendations for adults with diabetes. Diab Care 2013; 36:3821-42

• Evidence suggests that there is no ideal % of calories from carbohydrate, protein, and fat (B)

• Macronutrient distribution should be based on

individualized assessment of current eating patterns, preferences, and metabolic goals (E)

Optimal Composition of Macronutrients

control throughout the day

A high-protein breakfast offers greater glycaemic control than a high-carbohydrate breakfast

•PPG is lower

•Postprandial insulin response is lower

•GLP-1 response at lunch is higher

Behavior of fiber in the intestine Dietary Fibre – Behavior in Intestine

• Supplemented fiber intake ranged from 4.5 – 20 g/day

• Predominantly insoluble form but guar gum or glucomannan were used in several studies

• Weight loss achieved with fiber supplements administered as an adjunct to an energy restricted diet → modestly greater than

weight loss achieved with placebo

NUTREN® Diabetes meets Recommended Nutritional Targets

Choose a breakfast that will give you

slow-release energy.

Choose a snack that will keep your blood glucose

levels even between meals. Be careful of

high-fat or sugary snacks.

Choose a combination of protein, carbohydrates

and fresh vegetables for a

balanced meal.

Potential Ways to Incorporate NUTREN® Diabetes into meal plan


• Essential for every phase of management of T2DM

• Healthy choice / Portion-sizes

• Optimally done as part of a multidisciplinary team

• As part of weight reduction / maintenance (for patients with ↑ BMI) use of low calorie / high fibre options to substitute • No ONE-SIZE-FITS ALL … as in everything, INDIVIDUALISE!
