Chairman, President and Chief Executive Officer Kellanova at Kellanova
Thanks, Amit. slide number 22 splits our portfolio into category groups to help remind you of their relative sizes and growth rates. This view shows you how much each category group contributed to our strong organic net sales growth in the quarter and for the full year. Now let's review each of our regions, which are our reporting segments. We'll start with Kellanova in North America in slide number 23. North America's fourth quarter results continued to show the impact of rising elasticities across all of our categories. Recall that we entered 2023 with low service levels due to economy-wide bottlenecks and shortages and therefore, we elected to launch less innovation and to return to merchandising only after we were strongly confident that service levels have returned to normal levels.
This, in conjunction with category elasticity suddenly and rapidly rising negatively impacted our volumes, particularly in the second half. Despite lapping an unusually strong year earlier period, North America's operating profit grew strongly year-on-year in the fourth quarter, even accounting for the reimbursement of expenses related to transition services provided to WKKC in this year's quarter 4, North America's operating profit grew in the mid-single digits year-on-year, continuing to restore underlying gross profit margin and operating profit margin by more than projected. So in spite of slowing categories and amidst the organization undergoing significant change related to the spin-off, North America again delivered financially.
Within its key category groups, we can see the deceleration in top line growth caused by the rising elasticities. slide number 24 shows our North America snacks business, which experienced slowing category growth rates during the year. Volume growth rates in our categories did not worsen in the fourth quarter, though elasticities continued to edge higher. We continue to feel the impact of less innovation year-on-year particularly in crackers, and this will be addressed in 2024 when we return to a full innovation launch calendar. And we did see year-on-year increases in display activity and our return to merchandising and improving quality of displays will continue to gain traction as we head into the new year. It was a similar story in frozen foods, shown on slide number 25. Along with the frozen breakfast category, Eggo's consumption turned to a decline in the fourth quarter on rising elasticities.
MorningStar Farms continued to gain share but in a declining veg vegan category. We believe these conditions are transitory for both categories and expect better performance in 2024. So let's talk about what to expect from North America in 2024, indicated on slide number 26. First, with supply impediments well behind us, we are returning to full commercial activity in 2024. This starts with a full slate of innovation launches and it includes a full year of robust merchandising and display activity. We will also continue to support our focused brands with increased brand-building investment. The results should be improved in market performance and a gradual return to volume growth. And if you have been watching the Pop-Tarts bowl and Cheez-It bowl as well as the upcoming Pringles activation for Sunday's big game are good examples of how we plan to show up in 2024.
Now let's turn to Kellanova Europe in slide number 27. Here we finished the year with another strong quarter, yet again, delivering organic net sales growth on top of prior year growth. In a market that is extremely price sensitive, we were again able to realize double-digit price/mix growth through effective revenue growth management actions, though elasticity did rise impacting volume. Our organic net sales growth was 10% in the quarter and 9% for the full year. Europe delivered strong operating profit growth in the fourth quarter and full year. Granted, this was lapping a sharp year ago decline, but it did feature strong top line growth and better margin recovery than expected, getting its operating profit margin back to flat for the full year. On slide number 28, you can see that snacks, which represent over half of our sales in Kellanova Europe continued to lead our growth in this region.
Our double-digit organic growth in net sales, both in the quarter and for the full year was across all of our major subregions. Revenue growth management actions drove the growth, while volume declines remained relatively modest. The salty snacks category has slowed but remained in high single-digit growth across key markets and Pringles in the fourth quarter was tracking to gain share, led by the U.K. and Spain. In portable wholesome snacks, we have managed to outpace the category in the U.K. and Italy. In cereal, shown on slide number 29, you can see that we grew net sales organically in the quarter. This, too, is led by revenue growth management actions, while elasticities have been running higher in this category than in our snacks categories. We finished 2023 with organic net sales growth of about 1%. slide number 30 points to some elements to watch for in Europe in 2024.
We expect to deliver a seventh consecutive year of organic growth. The growth will be led by snacks with Pringles continuing to be supported with innovation and brand building and portable wholesome snacks in key markets, notably Pop-Tarts and Rice Krispies Squares. We're also excited about launching Cheez-It in key European markets in the second half. In cereal, our focus will be on optimizing our cereal portfolio in conjunction with the manufacturing network optimization that we're commencing this year. Now let's look at our emerging markets regions, starting with Latin America on slide number 31. In the fourth quarter, Latin America's net sales grew 5% on an organic and recast basis, with volume declines moderating even in spite of sizable impact from our SKU rationalization and price pack architecture initiatives.
The region finished the year with strong 8% organic net sales growth. Operating profit declined in the fourth quarter against a substantial year earlier gain. But despite some incremental investments and transitory cost pressures, it finished the full year with 8% growth on an adjusted and currency-neutral basis. slide number 32 shows that our snack sales were flat on an organic basis in the fourth quarter comparing against a notably strong year earlier period. Pringles continued to perform well. In-market data show sustained double-digit category growth for our major salty snacks markets with Pringles gaining share in Brazil and holding share in Mexico, and we continue to outpace the portable wholesome snacks category in Mexico, though we did see rising elasticities in cookies in Brazil. Our Latin America Snacks business finished the full year with 7% organic net sales growth.
In Latin America cereal, shown on slide number 33, our organic net sales growth was strong in the quarter and for the full year. Specifically, sales grew 10% in the quarter and finished the full year with 9% growth. Cereal category consumption growth has held up in the mid- to high single digits across much of the region, and we gained share in Mexico. As we look to 2024, a few things to watch for in Latin America are shown on slide number 34. We expect a seventh straight year of organic net sales growth. The growth should be led by snacks, particularly behind Pringles innovation and distribution expansion, and we also expect good growth in cereal. Margins should improve, reflecting price pack architecture and other RGM initiatives and operating efficiencies as well as moderating input cost pressures. slide number 35 shows the financial performance of our AMEA region.
This region sustained its strong momentum in the fourth quarter when organic net sales growth reaccelerated to 22% on a combination of price mix growth and volume growth led by Africa. For the full year, our organic net sales growth was 17%. Now obviously, a large portion of this currency neutral growth came from Nigeria, where currency devaluation necessitated significant pricing actions. Nevertheless, the rest of AMEA posted solid growth in the quarter as well. Margins continue to recover year-on-year, and operating profit grew 25% in the quarter on an adjusted and currency-neutral basis in spite of substantially higher brand investment and despite lapping strong prior year growth. Its operating profit increased by 20% for the full year. Within AMEA, we see on slide number 36, that snacks grew organically at a double-digit pace in the fourth quarter and for the full year.
This growth was led by Pringles in emerging markets across Asia, Africa and the Middle East as well as in more developed markets like Australia, Korea and Japan. Pringles continued to gain share overall, principally due to outperformance in Thailand, Australia and Japan. In cereal, shown on slide number 37, we sustained organic growth, posting 4% growth in the fourth quarter and 6% growth for the full year. This was led by emerging markets in Africa, the Middle East and Asia. And we finish with noodles and other shown on slide number 38. Revenue growth management actions continue to be taken in Nigeria as we try to keep up with weakened currencies but volume also grew in the double digits in the fourth quarter, reflecting the strength of our brands and our execution as well as timing of shipments.
Meanwhile, we also continue to expand our Kellogg's noodles business outside of Nigeria and this also contributed to our volume growth in the quarter. We expect AMEA to sustain momentum into 2024 as discussed on slide number 39. To deliver the region's 17th straight year of organic net sales growth, we expect to see strong growth if moderating from 2023 rates in noodles and other. We expect to see sustained momentum in snacks, led by Pringles, and we expect a sustained growth in cereal, led by emerging markets. Margin expansion should continue led by our businesses outside of Nigeria, in those markets, input cost pressures are finally moderating and productivity and operating leverage continued to contribute positively. So let me summarize with slide number 41. Simply put, the Kellanova era is off to a good start.
We've executed well the spin-off and the post spin-off operations, including transition services, and we delivered our initial quarter ahead of our expectations. We're now shifting back to a focus on demand generation after a few years of supply focus. We're very excited about our 2024 commercial plans which feature a return to a full complement of innovation, brand building, merchandising as well as sustaining momentum and scale building in our emerging markets. We're also pleased with our progress and plans for restoring and expanding profit margins, which has proceeded faster than we had anticipated. Our outlook for 2024 were shared with you as far back as last August remains intact, calling for another year of on-algorithm sales and profit growth, and we're not sitting still.
We're already creating the future. For instance, we are adding much needed capacity for Pringles in emerging markets. The international expansion of Cheez-It continues with launches coming in Europe, and we are commencing network optimization initiatives that will both expand margins and fuel growth investments. In sum, we are on track and ready to deliver as Kellanova, and the future certainly is bright. Of course, none of this would be possible without the grit and skill of our supremely talented Kellanova employees, all of whom are determined as ever to differentiate, drive and deliver.
And now we'd be happy to take your questions.
