Desirable Dietary Pattern for Bangladesh PI: Quamrun Nahar, PhD Co-Investigators Prof Subhagata Choudhury, BIRDEM Dr M Omar Faruque, BIRDEM Syeda Saliha Saliheen Sultana, HEC Dr MA Siddiquee, BRRI Introduction Food production has tripled since 1971. Rice production has increased from 9.77 mil MT in 1971 to 33.5mil MT in 2010 Food consumption at individual levels has also increased However diets remain monotonous, imbalanced and dominated by a high intake of cereals which is 70% Disproportionate consumption of cereals and non cereals foods is one of the factors leading to the double burden of malnutrition Current Nutrition situation in Bangladesh Indicator Prevalence (%) LBW Stunting (U5) Wasting (U5) Under weight (U5) Zinc deficiency Anaemia *World Health Statistics; BDHS 2011 22* 41 16 36 44 33.1 Prevalence of selected micronutrient deficiencies among non pregnant non lactating women Indicators Prevalence (%) Anaemia 26 Zinc deficiency 57.3 Iodine deficiency 42.1 National Micronutrient Survey 2011-12 Current Prevalence* of NCD Indicators Prevalence (%) DM 7.9a BMI > 25 18 HTN >140/90 14.8 Central obesity 21.7 *National NCD survey 2010; aInternational Diabetes Federation (IDF) Objectives • Estimate energy requirements by age, gender and physical activity levels namely sedentary, moderate and heavy work in rural and urban areas in Bangladesh • Compile nutrient requirements disaggregated by gender, age and physiological status (pregnancy, lactation) and physical activity levels • Develop diet plans that identify the types and quantities of foods required to provide energy and essential nutrients for a balanced diet of population disaggregated by gender, age, physiological status and physical activity levels in urban and rural areas with due attention to local food habits, food availability and biodiversity.

Take at least one cup (130 ml) milk/ doi for good source of calcium throughout the life for healthy bones and teeth 2. Eat curd or drink soya milk in case of lactose intolerance GUIDELINE 2: CONSUME MODERATE AMOUNTS OF OILS AND FATS • Vegetable oil like mustard oil and soybean oil, should be used in moderation daily instead of ghee, butter, butter oil and palm oil. • Limit intake of fat rich food, fast food, fat rich baked foods and processed meat that may add to undesirable trans-fats GUIDELINE 3: LIMIT SALT INTAKE AND CONDIMENTS AND USE ONLY IODIZED SALT Limit salt intake to half to one teaspoon (< 5g) a day. Use only iodized salt Reduce consumption of highly salted foods and condiments and avoid extra table salt with meals GUIDELINE 4: TAKE LESS SUGAR, SWEETS OR SWEETENED DRINKS • Refine sugar is known as a dietary disaster and it is advisable to reduce the intake sugar based food especially sweetmeats and rich desserts. • Encourage the intake of natural sugars from a variety of seasonal fruits. GUIDELINE 5: DRINK PLENTY OF WATER DAILY Drink 1.5 to 3.5 liter ( 6-14 glasses) clean and pure drinking water Drink coconut water and fresh fruit juices instead of carbonated water GUIDELINE 6: CONSUME SAFE AND CLEAN FOODS AND BEVERAGES • Choose fresh, safe and clean foods and beverages. • Eat vegetables and fruits after thorough washing to avoid microbes and bacteria • Avoid open street foods GUIDELINE 7: MAINTAIN DESIRED BODY WEIGHT THROUGH A BALANCED FOOD INTAKE AND REGULAR PHYSICAL ACTIVITY Key messages • Maintain normal BMI (18.5-23.0, kg/m2) along with Waist circumference (male: 90 cm, female: 80 cm and waist hip ratio (male : > 0.9; female 0.8) • Practise minimum thirty minutes of daily aerobic physical activities - walking, running, jogging, cycling, household work GUIDELINE 8: PRACTISE HEALTHY LIFE STYLE WITH RIGHT COOKING AND HEALTHY EATING • • • • • Key messages Eat food timely and avoid overeating Avoid reuse of fried oil Avoid faulty food beliefs, fads and fallacies Avoid sleeping immediately after major meals Avoid smoking, alcohol consumption and betel nut chewing GUIDELINE 9: EAT ADDITIONAL FOOD DURING PREGNANCY AND LACTATION Key messages • Eat beef, mutton or poultry or germinated pulses throughout pregnancy for getting dietary iron source • Eat seasonal fruits throughout pregnancy especially after meals • Maintain proper weight gain during pregnancy 12kg during pregnancy) GUIDELINE 10: PRACTISE EXCLUSIVE BREAST FEEDING FOR SIX MONTHS AND START APPROPRIATE COMPLEMENTARY FOODS IN TIME Key messages • Exclusively breast feed for six months for adequate growth of the child • Introduce appropriate complementary foods after completion of 6 months and continue complementary feeding along with breast feeding up to 2 years Conclusions The study provides an update on energy, macro and micronutrients requirement for all ages considering gender, PAL and physiological conditions adapted to FAO/WHO recommendations. Average energy requirement is 2430 kcal, current intake is deficient by 240 kcal. More than 50% dietary protein and iron sources are from plant sources. Micronutrient intake especially vitamin A, calcium, iron, zinc, folic acid are inadequate. The diet plans and menu options have been formulated considering dietary adequacy and nutrient gaps in Bangladeshi diets. Recommendations • The diets proposed can be adapted for use by both poor and non poor households in urban and rural areas. A variety of foods and food groups has been used in planning the diets so as to achieve a desirable dietary pattern with adequate dietary diversity scores. • The study findings can be considered for agriculture, food and diet planning where in updates on energy and nutrient requirements are needed. • The key nutrition messages can be considered for use in policy, programmes and field interventions across food, agriculture and health sectors.
