The Chinese Fd Guide Pagda is a graphic representatin f the quantity and prprtin f varius fds intake fr an adult accrding t the key recmmendatins frm Dietary Guidelines fr Chinese Residents (2022). It fllws the principle f a balanced diet and shws the basic fd cmpsitin in nutritin.
There are five levels n the Pagda, each f a different size, shwing the five categries f fd and their amunts. The categries f fd include cereals and tubers, fruits and vegetables, meat, pultry, dairy, sybeans, legumes and nuts, cking il and salt. The fd quantities are designed accrding t different energy demand levels. The ntes beside the Pagda indicate the recmmended range f daily intake per adult at the energy demand level f 1600~2400 kcal.
Level 1: Cereals and tubers Cereals and tubers are the main surces f dietary energy (carbhydrate prvides 50%~65% f ttal energy), and they are als gd surces f micrnutrients and dietary fiber. It is recmmended in the Dietary Guidelines that healthy peple ver tw years ld shuld eat diversified and balanced meals. A ttal daily intake f 200-300g f cereals, f which whle grains and legumes shuld make up 50-150g and tubers 50-100g, is recmmended.
Level 2: Vegetables and fruits Peple shuld eat enugh vegetables and fruits, accrding t the Dietary Guidelines. The recmmended daily intake f vegetables is 300g, half f which shuld be dark-clred, while the daily intake f fresh fruits shuld be 200-350g.
Level 3: Fish, pultry, meat, and eggs Fish, pultry, meat, and eggs are recmmended by the Dietary Guidelines fr mderate cnsumptin. Ttal intake shuld be targeted at 120-200g n a daily basis.
Level 4: Dairy, sybeans and nuts Dairy, sybeans and nuts are gd surces f prtein and calcium with high nutrient density. A wide variety f dairy prducts shuld be cnsumed, and a daily intake equivalent t 300g f liquid milk is recmmended.
Level 5: Cking il and table salt Cking il and table salt are indispensable as cking cndiments, but it is better t use them as little as pssible. The daily intake f salt and cking il fr an adult shuld be less than 5g and 25-30g respectively. Accrding t the recmmendatins f DRIs , the dietary fat energy supply rati shuld accunt fr 35% f the ttal dietary energy fr peple aged 1~3 years ld; fr peple ver fur years ld, it shuld be 20%~30%.
