These healthy diets were associated with lower risk of death, according to a study of 119,000 people across four decades

Eat healthy, live longer.

That’s the takeaway from a major study published this month in JAMA Internal Medicine. Scientists led by a team from the Harvard TH Chan School of Public Health found that people who most closely adhered to at least one of four healthy eating patterns were less likely to die from cardiovascular disease, cancer or respiratory disease compared with people who did not adhere as closely to these diets. They were also less likely to die of any cause.

“These findings support the recommendations of Dietary Guidelines for Americans that multiple healthy eating patterns can be adapted to individual food traditions and preferences,” the researchers concluded, adding that the results were consistent across different racial and ethnic groups. The eating habits and mortality rates of more than 75,000 women from 1984 to 2020 over 44,000 men from 1986 to 2020 were included in the study.

The four diets studied were the Healthy Eating Index, the Alternate Mediterranean Diet, the Healthful Plant-Based Diet Index and the Alternate Healthy Eating Index. All four share some components, including whole grains, fruits, vegetables, nuts and legumes. But there are also differences: For instance, the Alternate Mediterranean Diet encourages fish consumption, and the Healthful Plant-Based Diet Index discourages eating meat.

The Alternate Mediterranean Diet is adapted from the original Mediterranean Diet, which includes olive oil (which is rich in omega-3 fatty acids), fruits, nuts, cereals, vegetables, legumes and fish. It allows for moderate consumption of alcohol and dairy products but low consumption of sweets and only the occasional serving of red meat. The alternate version, meanwhile, cuts out dairy entirely, only includes whole grains and uses the same alcohol-intake guideline for men and women, JAMA says.

The world’s ‘best diets’ overlap with study results

The Mediterranean Diet consistently ranks No. 1 in the US News and World Report’s Best Diets ranking, which looks at seven criteria: short-term weight loss, long-term weight loss, effectiveness in preventing cardiovascular disease, effectiveness in preventing diabetes, ease of compliance, nutritional completeness and health risks. The 2023 list ranks the top three diets as the Mediterranean Diet, the DASH Diet and the Flexitarian Diet.

The DASH (Dietary Approaches to Stop Hypertension) Diet recommends fruits, vegetables, nuts, whole grains, poultry, fish and low-fat dairy products and restricts salt, red meat, sweets and sugar-sweetened beverages. The Flexitarian Diet is similar to the other diets in that it’s mainly vegetarian, but it allows the occasional serving of meat or fish. All three diets are associated with improved metabolic health, lower blood pressure and reduced risk of Type 2 diabetes.

Frank Hu, a professor of nutrition and epidemiology at the Harvard School of Public Health and co-author of the latest study, said it’s critical to examine the associations between the US government’s Dietary Guidelines for Americans and long-term health. “Our findings will be valuable for the 2025-2030 Dietary Guidelines Advisory Committee, which is being formed to evaluate current evidence surrounding different eating patterns and health outcomes,” he said.

Reducing salt intake is a good place to start. In 2021, the Food and Drug Administration issued new guidance for restaurants and food manufacturers to, over a two-and-a-half-year period, voluntarily reduce the amount of sodium in their food to help consumers stay under a limit of 3,000 milligrams per day — still higher than the recommended daily allowance. Americans consume around 3,400 milligrams of sodium per day, on average, but the Centers for Disease Control and Prevention recommends that people consume less than 2,300 milligrams each day.

Opinion: This record number in Nvidia earnings is a scary sight

Nvidia Corp.’s financial results had a bit of a surprise for investors, and not on the good side — product inventories doubled to a record high as the chip company gears up for a questionable holiday season.

Nvidia reported fiscal third-quarter revenue that was slightly better than analysts’ reduced expectations Wednesday, but the numbers weren’t that great. Revenue fell 17% to $5.9 billion, while earnings were cut in half thanks to a $702 million inventory charge, largely relating to slower data-center demand in China.

Gaming revenue in the quarter fell 51% to $1.57 billion. Nvidia said it is working with its retail partners to help move the currently high-channel inventories.

While the company was writing off the inventory for China, its own new product inventory was growing. Nvidia NVDA,
reported that its overall product inventory nearly doubled to $4.45 billion in the fiscal third quarter, compared with $2.23 billion a year ago and $3.89 billion in the prior quarter. Executives cited its coming product launches, designed around its new Ada and Hopper architectures, when asked about the inventory gains.

In the semiconductor industry, high inventories can make investors nervous, especially after the industry had so many supply constraints in recent years that quickly swung to a glut of chips in 2022. With doubts about demand for gaming cards and consumers’ willingness to spend amid sky -high inflation this holiday season, having all that product on hand just amps up the nerves.

Chief Financial Officer Colette Kress told MarketWatch in a telephone interview Wednesday that the company’s high level of inventories were commensurate with its high levels of revenue.

“I do believe….it is our highest level of inventory,” she said. “They go hand in hand.” Kress said she was confident in the success of Nvidia’s upcoming product launches.

Nvidia’s revenue reached a peak in the April 2022 quarter with $8.3 billion, and in the past two quarters revenue has slowed, with gaming demand sluggish amid a transition to a new cycle, and a decline in China data-center demand due to COVID-19 lockdowns and US government restrictions.

For its data-center customers, the new architectures promise major advances in computing power and artificial-intelligence features, with Nvidia planning to ship the equivalent of a supercomputer in a box with its new products over the next year. Those types of advanced products weigh on inventory totals even more, Kress said, because of the price of the total package.

“It’s about the complexity of the system we are building, that is what drives the inventory, the pieces of that together,” Kress said.

Bernstein Research analyst Stacy Rasgon believes that products based on Hopper will begin shipping over the next several quarters, “at materially higher price points.” He said in a recent note that he believes Nvidia’s numbers were likely hitting a bottom in this quarter.

“We remain positive on the Hopper ramp into next year, and believe numbers have at this point likely reached close to bottom, with new cycles brewing and an attractive secular story even without China potential,” Rasgon said in an earnings preview note Tuesday.

Nvidia Chief Executive Jensen Huang reminded investors on a conference call that the company’s inventories are “never zero,” and said everyone is enthusiastic about the upcoming launches. But it doesn’t take too long of a memory to conjure up a time when Nvidia went into a holiday with an inventory backlog that included new architecture and greatly disappointed investors: Four years ago, Huang had to cut his forecast for holiday earnings twice amid a “crypto hangover” with similar dynamics to the current moment

Investors need faith that this holiday season will not be the same, even as demand for some videogame products declines after a pandemic boom just as the market for cryptocurrency — some of which has been mined with Nvidia products — hits a rough patch. Huang said that Nvidia’s RTX 4080 and 4090 graphics cards based on the Ada Lovelace architecture had an “exceptional launch,” and sold out.

Nvidia shares gained more than 2% in after-hours trading Wednesday, suggesting that some are betting that this time will be different. That enthusiasm needs to translate into revenue for Nvidia so that this big gain in inventories does not end up being part of another write-down at some point in the future.



Opinion: Tesla investors have been the biggest losers in Elon Musk’s Twitter deal, and those losses continue

Twitter users have complained a lot about Elon Musk’s early moves after taking control of the social network, but their complaints seem tiny compared with what Tesla Inc. investors have had to suffer.

As the US focused on election returns Tuesday evening, Tesla TSLA,
Chief Executive Musk tried to slip through disclosure of his long-awaited stock sales, revealing that he had sold nearly $4 billion of Tesla stock in the previous three trading sessions. Musk did not publicly address the stock sales nor his intentions to sell more within 24 hours of the disclosure, even while tweeting roughly 20 times in that period.

[MarketWatch asked him on Twitter to address the sales twice, and did not receive a reply; Tesla disbanded its media-relations department years ago.]

The sales fueled a further downturn in shares of the electric-vehicle maker on Wednesday, when the stock fell 7.2% to $177.59, its lowest closing price since November 2020. Tesla is currently down 49.6% on the year, which would be far and away the worst year yet for the stock — the previous record annual decline was 2016, when it fell 11%.

The problems for Tesla investors go far beyond Musk selling its stock so that he could overpay for a company with limited growth prospects and a host of other problems, but the poor optics certainly start there.

“He sold caviar to buy a $2 slice of pizza,” said Dan Ives, a Wedbush Securities analyst.

Ives was one of several on Wall Street to predict Musk would need to sell more shares to either close a gap in his financing of the $44 billion deal to buy the social-media company, or provide additional operating funds. In a telephone conversation Wednesday, he said the Twitter move is “a nightmare that just won’t end for Tesla investors.”

One reason it isn’t ending is that Musk’s need for cash in relation to Twitter is not done with the recent sales, portending more in the future. Musk said in a tweet late last week that Twitter had a “massive drop in revenue” due to activists pressing advertisers to pull their ads, and he will have to continue paying the employees he did not lay off while servicing a debt load that analysts have estimated will cost him $1 billion a year, much more than Twitter has cleared in profit in the past two years. Twitter reported a net loss of $221 million in 2021, and a net loss of $1.13 billion for 2020.

“The first two weeks of ownership have been a ‘Friday the 13th‘ horror show,” Ives said, adding that the verification plan and mass layoffs of 50% of employees — and then trying to rehire some of the engineers, developers and cybersecurity experts — was “really stupid.” And, according to CNBC, Musk has also pulled more than 50 Tesla engineers, many from the Autopilot team, to work at Twitter.

“But it’s consistent with how this thing has been handled,” Ives said, adding that Musk is “way over his skis” with the Twitter acquisition.

Amid all the chaos of his first two weeks running Twitter, how much time has Musk had to run his other companies? Musk was already splitting his Tesla time with SpaceX, The Boring Company, Neuralink and many other endeavors, and now he has taken on the gargantuan task of turning a social-media company that has never been highly profitable, nor valuable, into something worth the $44 billion he paid.

The effort, Ives said, has “tarnished his brand,” which in turn has a big risk of hurting Tesla. Many investors have bought into the Tesla story because they believe Musk is a genius and they back his vision of electrifying the automotive industry. Twitter does not meld into that vision, except as a platform to spout his opinions, vitriol and promote more wacky concepts.

Since Musk began his quest to buy the company, he has endured more criticism than ever before, with even some fans starting to throw shade or question his decisions. Investor Gary Black, managing partner of the Future Fund LLC, for example, pointed out that Tesla’s top engineers should not be running Twitter, where the news was getting worse.

Tesla is not a company that can just run itself at this point. Musk has claimed he did not want to be chief executive but that there was no one else to take over the car company, which is why he has served as CEO for years. It’s not clear, though, how much effort he actually has made at trying to recruit someone. Now, as Tesla faces its usual multitude of issues, he is off spending his time trying to turn Twitter into a payments company, or maybe a subscription company, or maybe an “everything app,” or whatever he comes up with tomorrow.

“Musk needs to look in the mirror and end this constant merry-go-round of Twitter overhang on the Tesla story, with his focus back on the golden child Tesla, which needs his time more than ever given the soft macro, production/delivery issues in China, and EV competition increasing from all corners of the globe,” Ives wrote in a note Wednesday, in which he reiterated an outperform rating on Tesla stock.

For Twitter to reach anywhere close to the valuation Musk paid for it, it’s going to need a ton of attention from a focused leader, but how can Musk be that leader and give Tesla the attention it deserves? The answer is he cannot, and is very likely to give the attention that Tesla needs to Twitter instead after committing $44 billion (not all of it his) to that endeavor. Tesla investors will be left staring at the sea of ​​red that this year has wrought, and wondering if its leader is about to sell more shares to fund his other effort.
