I just visited a Costco in Japan—the variety of foods was 'incredible': 6 things I wish they sold in the American stores

CNBC2 days ago
As a Japanese nutritionist living in the U.S., I love shopping for traditional foods that I grew up eating, such as seaweed, beans, matcha, multigrain rice, and sweet potatoes.
I sometimes go to Costco to buy those staples in bulk. But during a recent trip to Japan, I had the chance to shop at the Costco Yawata Warehouse in Kyoto, which you can visit using your U.S. membership card.
I was curious to see how it compared to the American stores, and I ended up being very surprised.
While the layout and many of the products were similar to the U.S. stores, the variety of Japanese foods was incredible. There were regional items, seasonally sourced ingredients, and healthier snacks that I rarely find back home. It was fun to browse through the foods and brands that were exclusive to stores in Japan.
Here are six things I wish U.S. Costco stores carried more of.
Seaweed is a staple in Japan. It's packed with minerals, vitamins, and polyphenols, making it one of the most nutrient-dense, plant-based foods you can eat.
I found a wide selection, including:
Other varieties included kombu, hijiki, aonori, and kanten — all of which I like to keep in my pantry.
Tofu is one of my favorite foods. It's a great source of plant-based protein and is very versatile across cuisines. You can eat it plain or throw it in soups or salads. Even my dogs enjoy it!
Japanese Costcos sell an amazing variety of soy-based items, many of which are vacuum-sealed for freshness and shelf-life. Options included:
One of my go-to recipes involves soaking koya tofu, cutting it into cubes, then simmering with kombu, dried shittake mushrooms, carrots, peas, and ginger. I finish it with homemade miso paste for a satisfying, balanced dish.
I always encourage my clients to incorporate a wide range of vegetables, roots, and herbs into every meal. Greater plant variety means more fiber, antioxidants, and essential nutrients for a long life.
I was excited to see all kinds of produce that are a little harder to find in American supermarkets:
Even the potatoes from Hokkaido, known for their high quality, were available in bulk.
I love to cook, but sometimes life gets busy and I need fast, healthy options for myself and my clients.
Costco Japan offered a smart range of ready-to-eat items, including (my favorite) microwavable multigrain rice bowls, pickled vegetables, instant miso soups in both powdered and paste form (just add hot water and throw in some seaweed and tofu), Japanese-style cooked fish, and many unique condiments.
Of course, you can find some of these items in American stores, like Whole Foods, but they're often pricier.
Rice crackers (soy-flavored rice crisps) are one of my favorite snacks. At Costco Japan, I saw kakino-tane, crescent-shaped crackers often mixed with peanuts. Other rice crackers were made with sesame seeds, seaweed, soy powder, nuts, and even some herbs.
In Japan, green tea is more than just a beverage — it's a daily ritual. You'll find it in vending machines, restaurants, and pretty much in every home.
At Costco Japan, I saw bottled green teas, tea bags and loose-leaf options, and powdered teas in family-sized packages. Almost every shopper had a green tea product in their cart.
Green tea has been associated with better heart health and longer life in many studies. I always recommend swapping it in place of soda for a low-calorie, antioxidant-rich alternative.

Dr. Cory Franklin: Why the US is better than Europe at preventing heat deaths

When it comes to reporting on the comparative health of nations, there is ample bias in the national and international press about American shortcomings. Some of it is justified — disproportionate numbers of obesity and firearm deaths are usually cited by medical and nonmedical sources, as well as the relatively high infant mortality. But no less important are environmental deaths, specifically those related to hot and cold weather, which are rarely cited. The U.S. figures are far more impressive than those of the rest of the industrialized world, and it is inarguable that this country does a much better job of preventing heat and cold deaths than Europe does. First, heat deaths: Comparisons of heat deaths between countries are limited because numbers vary according to how heat deaths are defined, the differences in weather and patient characteristics in various countries, and the sources of the data. The numbers here are a compendium from several sources including Lancet, Nature and several public health and weather websites; mileage may vary. Taking all this into account, the difference in annual heat deaths between Europe and the U.S. is surprising: In the 21st century, European heat deaths on average range from 60 to 200 per 1 million people annually, while American heat deaths average about three to eight per million annually. This means, conservatively, each year, perhaps 20 times as many people die of the heat in Europe as in the U.S. A graphic example: During the recent European heat wave that began in May, one country, Spain, experienced 1,180 deaths in only two months. The data from deaths due to cold weather are even more sobering. Even with a warming Earth, cold continues to kill more people than heat in most parts of the world where there is any kind of cold winter. In Europe, there are 300 to 500 deaths per million due to cold annually in the past three decades, while in the U.S., the number of deaths from cold is in the range of 10 per million. So a conservative estimate would be that for every person who dies as a result of cold weather in the U.S., at least 30 die in Europe. When deaths from heat and cold are combined, Europe has close to 50 times as many deaths as the U.S. — as many as 250,000 to 500,000 more deaths every year. Over a decade, this means several million more people die from heat and cold in Europe than die in the U.S. from those causes. A comparison of the annual numbers shows that the difference in environmental deaths easily surpasses the much more widely reported firearm death comparison. The U.S. has nearly 50,000 firearm deaths annually, and Europe has under 10,000, so the difference in firearm deaths, roughly 40,000, is about 1/10th the difference in environmental deaths. Why is there such a difference in environmental deaths between the U.S. and Europe? The consensus among experts regarding heat deaths is the ubiquity of air conditioning in the U.S. and the relative paucity in Europe. (The majority of deaths in Spain during the May-June heat wave were in the north of the country, where air conditioning is uncommon compared with in the south.) Besides providing comfort, air conditioning saves lives — often many — especially if air conditioning could be made more available in the Global South, where there are even more deaths due to hot weather. Despite the consensus, some environmentalists want to limit air conditioning, citing increased electricity use and carbon dioxide production, which will aggravate greenhouse gas emissions. (In 2022, Spain was one of the countries that put restrictions on air conditioning.) The response to climate change must involve a combination of mitigation, such as reducing levels of heat-trapping greenhouse gases and adaptation — that is, adapting to the consequences of a warming environment. According to Hannah Ritchie, deputy editor of the Our World in Data website, air conditioning currently accounts for about 7% of global electricity use and 3% of carbon dioxide emissions — not negligible but certainly not exorbitant considering how many lives cooling technology saves. While worldwide air conditioning use is expected to increase in the next decade, so is the efficiency of air conditioning units. Air conditioning represents one of the most effective and lifesaving methods of adaptation to a changing climate. The reasons for increased cold weather deaths in Europe relative to the U.S. are harder to divine, but likely include the ubiquity of older homes with poorer insulation throughout Europe. Outside of Scandinavia, there may be less preparedness and an aging population more vulnerable to cold weather snaps on the European continent. Human-made efforts to reduce greenhouse gases are essential, but human-made efforts to adapt to weather extremes would have lifesaving consequences more immediately.

Walmart rewords Virginia pop-up tying condom searches to data consent

Pushback on the Walmart website warning Virginia users to avoid searching for or buying reproductive or sexual health products if they don't consent to their information being collected has led the retailer to change the pop-up's wording. Why it matters: The message raised questions from some shoppers and a state senator about how major retailers are interpreting and complying with the new reproductive health privacy protections in Virginia. State of play: Those protections, which took effect July 1, are part of a law that bans the collection or sale of identifiable reproductive health data without explicit consent from the consumer. That information can be related to buying birth control, condoms and pregnancy tests. But Virginians will see the Walmart pop-up simply by being on the website. Catch up quick: Walmart's original message said that viewing such products on its site means you consent to sharing your data. While that language has been scaled back, the retail giant's new wording still suggests Virginians who use the site are automatically consenting to having limited information collected since there's no opt-out option. The new law doesn't explicitly require businesses to offer an opt-out. Zoom in: State Sen. Barbara Favola, who sponsored the law, called Walmart's initial message " over-encompassing" earlier this month, but she told Axios on Friday that the new pop-up is "a warmer version." She said a workgroup will submit changes refining the law next year. Walmart spokesperson Marilee McInnis told Axios that Walmart will "continue to assess the best way" to "inform customers how we use certain types of information," as per the new law. McInnis also said Walmart doesn't sell Virginia consumer health information or use it for targeted advertising. Between the lines: Walmart, as of an Axios review on Friday, is one of the only big retailers with a visible message on its landing page regarding the new law. Costco, when you click on condoms or birth control pills, shows a message under product details saying searching or buying "a health care product or service" implies consent to data collection. CVS, Target, Amazon and Walgreens do not have similar notes.

Israeli strikes kill at least 34 people in Gaza, officials say, as some aid restrictions are eased

Advertisement Aid agencies have welcomed the new aid measures, which also included allowing airdrops into Gaza, but said they were not enough to counter the rising hunger in the Palestinian territory. Images of emaciated children have sparked outrage around the world, including from Israel's close allies. U.S. President Donald Trump on Sunday called the images of emaciated and malnourished children in Gaza 'terrible.' Israel has restricted aid to varying degrees throughout the war. In March, it cut off the entry of all goods, including fuel, food and medicine to pressure Hamas to free hostages. Israel partially lifted those restrictions in May but also pushed ahead on a new U.S.-backed aid delivery system that has been wracked by chaos and violence. Traditional aid providers also have encountered a similar breakdown in law and order surrounding their aid deliveries. Advertisement Most of Gaza's population now relies on aid. Accessing food has become a challenge that some Palestinians have risked their lives for. The Awda hospital in central Gaza said it received the bodies of seven Palestinians who it said were killed Monday by Israeli fire close to an aid distribution site run by the U.S.- and Israeli-backed Gaza Humanitarian Foundation. The hospital said 20 others were wounded close to the site. Elsewhere, a woman who was seven months pregnant was killed along with 11 others after their house was struck in the Muwasi area, west of the southern city of Khan Younis. The woman's fetus survived after a complex surgery, according to the Palestinian Red Crescent. One strike hit a two-story house in the western Japanese neighborhood of Khan Younis, killing at least 11 people, more than half of them women and children, said the Nasser Hospital, which received the casualties. The Israeli military and GHF did not immediately respond to a request for comment on those strikes. In its Oct. 7, 2023, attack, Hamas killed 1,200 people and took 251 hostages. It still holds 50, more than half Israel believes to be dead. Israel's retaliatory offensive has killed more than 59,800 Palestinians, according to Gaza's Health Ministry. Its count doesn't distinguish between militants and civilians, but the ministry says over half of the dead are women and children. The ministry operates under the Hamas government. The U.N. and other international organizations see it as the most reliable source of data on casualties. Magdy reported from Cairo.
