Vietnam had held the fourth spot since 2012, but this was taken by India last year, with a consumption of 5.4 billion packs.
Other countries in the top five were China (38.9 billion packs); Indonesia (12.6 billion); and Japan (5.6 billion).
With population over 93 million, Vietnam is second among 2017’s top 3 countries with the highest per capita instant noodles consumption at 53.5 servings; behind South Korea with 73.7 servings and above Nepal with 51.1 servings.
In 2016, the average Vietnamese person gobbled 53 packs of instant noodles, higher than Indonesians at 49, Japanese at 44 and Chinese people at 38.
Local enterprises have tapped into this huge market by partnering with overseas companies, increasing the options manifold for the Vietnamese consumer.
Domestic instant noodle enterprises have reported rising sales, reflecting the increasing consumption.

Globally, some 100 billion servings of instant noodles were sold in 2017, an average of 270 million packages consumed per day.
FoodDive, an online news site in food industry, quoted an IMARC Group report as saying the global instant noodles market value reached $40 billion in 2017 and is expected to reach $55 billion in 2023.
