Pengaturan diet dengan pemilihan jenis dan jumlah makanan berindeks glikemik rendah merupakan salah satu cara yang dapat dilakukan oleh diabetisi dalam penatalaksanaan diet. Peneliti ingin memodifikasi puding ubi jalar putih dengan penambahan buah naga merah untuk mendapatkan produk pangan dengan indeks glikemik dan kadar karbohidrat rendah serta kadar serat tinggi. Tujuan: Penelitian ini bertujuan untuk menganalisis indeks glikemik, kandungan gizi (kadar karbohidrat dan kadar serat) serta daya terima puding ubi jalar putih dengan penambahan buah naga merah sebesar 25%, 50%, dan 75%. Metode: Metode penelitian yang digunakan adalah true eksperimental dengan post-test only control design. Subjek penelitian sebanyak 10 orang mahasiswa untuk uji indeks glikemik dan 25 orang penderita diabetes melitus untuk uji daya terima. Hasil: Indeks glikemik puding dengan 4 taraf perlakuan (K, P1, P2, dan P3) adalah 37,75; 33,81; 32,81; dan 29,54. Semakin tinggi penambahan buah naga merah dapat menurunkan kadar karbohidrat dan kadar serat puding. Puding dengan penambahan buah naga merah 75% adalah puding yang paling disukai oleh panelis. Kesimpulan: Kesimpulan dari penelitian ini yaitu tidak terdapat perbedaan yang signifikan terhadap penambahan buah naga merah pada puding ubi jalar putih.

Researchers want to modify the white sweet potato pudding with addition of red dragon fruit to obtain low glycemic index, low carbohydrate, and high fiber food products. Objective: The purpose of this study was to analyze the glycemic index, nutrient content, and the acceptance capability of white sweet potato pudding with addition of red dragon fruit by 25%, 50%, and 75%. Method: The research method used is true experimental with post-test only control design. The researcher subject were 10 student for index glicemyc test and 25 diabetics patient for acceptance capability. Result: The pudding glycemic index with 4 treatment (K, P1, P2, and P3) were 37.75; 33.81; 32.81; and 29.54. The higher addition of red dragon fruit can pudding low carbohydrate and fiber level. Pudding with addition of 75% red dragon fruit was the the most preferred pudding by panelists.
