Mitundu yatsopano yowonjezeramo niacin imakhala ndi zovuta zochepa. Nicotinamide siyimayambitsa zotsatirazi.

ZOKHUDZA ZOLEMBEDWA

Malangizo a niacin ndi zakudya zina amaperekedwa mu Dietary Reference Intakes (DRIs), omwe amapangidwa ndi Food and Nutrition Board ku Institute of Medicine. DRI ndiye nthawi yamagulu omwe amagwiritsidwa ntchito pokonza ndikuwunika momwe michere ya anthu athanzi ilili. Izi, zomwe zimasiyana zaka komanso kugonana, zimaphatikizapo:

• Analimbikitsa Dietary Allowance (RDA): kuchuluka kwa chakudya tsiku lililonse chokwanira kukwaniritsa zofunikira za michere pafupifupi anthu onse (97% mpaka 98%) athanzi.
• Kuyika Kokwanira (AI): pakakhala kuti palibe umboni wokwanira wopanga RDA, AI imayikidwa pamlingo womwe umaganiziridwa kuti umapatsa thanzi chakudya chokwanira.

Kufotokozera Zakudya za Niacin:

Makanda

• Miyezi 0 mpaka 6: 2 * mamiligalamu patsiku (mg / tsiku)
• Miyezi 7 mpaka 12: 4 * mg / tsiku

Kudyetsa Kokwanira (AI)

Ana (RDA)

• 1 mpaka 3 zaka: 6 mg / tsiku
• Zaka 4 mpaka 8: 8 mg / tsiku
• Zaka 9 mpaka 13: 12 mg / tsiku

Achinyamata ndi Akuluakulu (RDA)

• Amuna azaka 14 kapena kupitilira apo: 16 mg / tsiku
• Azimayi azaka 14 kapena kupitilira apo: 14 mg / tsiku, 18 mg / tsiku panthawi yapakati, 17 mg / tsiku pa mkaka wa m'mawere

Malangizo apadera amatengera zaka, kugonana, ndi zina (monga mimba). Amayi omwe ali ndi pakati kapena akuyamwitsa amafunika ndalama zambiri. Funsani omwe amakupatsani omwe ali abwino kwa inu.

Njira yabwino yopezera mavitamini ofunikira tsiku ndi tsiku ndi kudya chakudya chopatsa thanzi chomwe chili ndi zakudya zosiyanasiyana.
