Goals for MNT in GDM •Optimal nutrition and weight gain for fetus and mother •Maternal euglycemia •Reduce the risk of diabetes related complications for the mother and child •Minimize the maternal and infant morbidity and mortality rates •Integrate diet, activity and pharmalogic therapy •Introducing healthy habits that can prevent or delay onset of type 2 DM 3
Assessing from an Interview • Age • Obstetric history • Weight History • Significant medical history (co-morbidities) • Food preferences and eating habits • Food Allergies • Individual psychological, social and physical status • Lifestyle, culture, and socio-economic status • Oral health • Readiness to change
4
Assessing from Clinical Information Laboratory tests to determine clinical status OGTT, fasting glucose, HbA1c level SMBG Urine ketones and proteins lipid profile (cholesterol — HDL, LDL) Haemoglobin, creatinine, thyroid function Blood pressure
Anthropometric Data Height , Weight and BMI
Current medications and nutrition supplements 5
Body Mass Index (BMI) Use pre pregnancy weight for calculations Weight and height measurements to calculate BMI: BMI = weight in kg/(height in m)2 Standard BMI normograms: Asian Underweight
ADA norms <18.5 kg/m2
Normal BMI
18.0-22.9 kg/m2
18.5-24.9 kg/m2
Overweight
23.0-24.9 kg/m2
25.0-29.9 kg/m2
Obesity
>25 kg/m2
> 30 kg/m2
6
Weight Gain Chart •Plot weight on a prenatal weight gain grid to obtain an accurate assessment of total pregnancy weight gain and rate of weight gain. •Determine if weight gain is above, at or below the recommended range. •If weight gain has already exceeded the recommended range, slow weight gain in order to prevent further excess gain.

Nutrition Assessment Nutrition history ď&#x201A;§ usual food intake recorded through interview
Dietary recall ď&#x201A;§ food and drink consumed in previous 24 hours (24-hour recall)
8
Activity â&#x20AC;&#x201C; Think of things to check for when doing a dietary history.
9
Issues with Dietary Recalls •Based on memory •Based on willingness to disclose the truth to a healthcare provider •Nutrient intake and long-term habits are not represented •Accurate estimations of food quantities/ingredients are difficult

12
Recommendations for Weight Gain Singleton pregnancy • Where possible a dietitian should develop a meal plan. • At about the 4th month of the pregnancy about 350 calories should be added daily. This should mean the woman is eating about 1900-2000 calories a day. • Overweight women (BMI 23 and over before pregnancy) should increase less. • Underweight women (BMI less than 18 before pregnancy) could add more. Institute of Medicine : 2009 13

Fluids
•Essential for all body functions •40-60% of body weight is water •Important to drink adequate amounts of fluid •Restrictions may be required in case of pedal edema
15
Proteins • Provide amino acids • Help to build muscle mass • Animal sources • Plant sources • 1 g of protein gives 4 kcal energy
16
Protein Recommendations •1.1 g protein per kg bodyweight per day •10-35% of total energy per day •Animal protein often high in fat, especially saturated. •Attention must be paid to meeting the protein requirements of women who are vegetarians or vegans
17
Carbohydrates
• Provide main source of energy for the body (45-65%) – individualized • Nutrient that most influences blood glucose levels • Source of simple sugars – glucose, fructose • 1 g of carbohydrate provides 4 kcal 18
Activity Name some of the common carbohydrates and staple foods in your region.

Benefits of Fibre A high-fibre diet is healthy Mixture of soluble and insoluble fibre - slows absorption of glucose - reduces absorption of dietary fats - retains water to soften stool - may reduce the risk of colon cancer - may reduce the risk of heart disease
22
Fibre Recommendations Recommended amounts of total fibre : 28 g per day Sources of insoluble fibre include: wheat bran, whole grains, seeds, fruits and vegetables Sources of soluble fibre: legumes (beans), oat bran, barley, apples, citrus fruits

29
Fats • The most concentrated source of energy • Foods may contain fat naturally or have it added during cooking • 1 g fat provides 9 kcal
30
Fat Recommendations Low in polyunsaturated fats (up to 10% of total daily energy) High in monounsaturated fats (>10%) Low in saturated fats (<10%) Trans or hydrogenated fat should be avoided
IoM 2002
31
Fats • Common sources of different fats • Polyunsaturated – safflower oil, sunflower oil, corn oil • Monounsaturated – olive oil, canola oil, rape seed oil, groundnut oil, mustard oil, sesame oil • Saturated – red meats, butter, cheese, margarine, ghee (clarified butter), whole milk, cream, lard • Trans fats – baked products, biscuits, cakes
32
Activity Identify major sources of fats in foods in your region.
33
Vitamins • Organic substances present in very small amounts in food • Essential to good health • A balanced meal automatically provides all necessary vitamins • Either fat-soluble or water-soluble • In some countries foods are “fortified” with vitamins and minerals
34
Vitamin Recommendations Daily multivitamin supplement should be added as they are often not met by diet alone. Multivitamin content varies depending on the product used. Women at higher risk for dietary deficiencies include multiple gestation, heavy smokers, adolescents, complete vegetarians, substance abusers, and women with lactase deficiency. 35
Minerals •Substance present in bones, teeth, soft tissue, muscle, blood and nerve cells •Help maintain physiological processes, strengthen skeletal structures, preserve heart and brain function and muscle and nerve systems •Act as a catalyst to essential enzymatic reactions •Low levels of minerals puts stress on essential life functions 36
Minerals And Trace Elements • A balanced diet supplies minerals and trace elements • Supplements are important as requirements are higher during pregnancy Calcium supplementation Iron supplementation Folic acid supplementation 0.4mg (should be started three months prior to conception)
CDA , 2013

38
Lowering Salt Intake • Sodium content is often high in restaurant foods • Encourage meal plans with • more fresh foods – fruits and vegetable • less processed, fast, convenience or canned foods • herbs and spices used when cooking instead of salt. • Teach people to read food labels. • Choose salt free, reduced or low in sodium foods
39
Substance Use The following substances should be avoided completely once the woman plans a pregnancy
Tobacco in any form Alcohol Drugs (street, illegal)
40
Sweeteners Sweeteners that increase blood glucose Sugar, honey Polydextrose & Sugar alcohols – maltitol, sorbitol, Xylitol
Sweeteners that do not increase blood glucose Acesulfame potassium Aspartame *Must be avoided during Cyclamate* pregnancy Saccharin* Sucralose To check with Health care team prior to starting use of sweeteners
