 — 

A low-carb, high-fat “keto-like” food plan could also be linked to larger ranges of “unhealthy” ldl cholesterol and double the chance of cardiovascular occasions equivalent to blocked arteries, coronary heart assaults and strokes, based on new analysis.

“Our examine discovered that common consumption of a self-reported food plan low in carbohydrates and excessive in fats was related to elevated ranges of LDL ldl cholesterol – or “unhealthy” ldl cholesterol – and a better danger of coronary heart illness,” lead examine writer Dr. Iulia Iatan with the Wholesome Coronary heart Program Prevention Clinic, St. Paul’s Hospital and College of British Columbia’s Centre for Coronary heart Lung Innovation in Vancouver, Canada, mentioned in a information launch.

Within the examine, researchers outlined a low-carb, high-fat (LCHF) food plan as 45% of whole each day energy coming from fats and 25% coming from carbohydrates. The examine was offered Sunday on the American Faculty of Cardiology’s Annual Scientific Session Collectively With the World Congress of Cardiology.

“Our examine rationale got here from the truth that we might see sufferers in our cardiovascular prevention clinic with extreme hypercholesterolemia following this food plan,” Iatan mentioned throughout a presentation on the session.

Hypercholesterolemia, or excessive ldl cholesterol, will increase an individual’s danger of coronary heart assault or different adversarial cardiovascular occasions.

“This led us to marvel concerning the relationship between these low-carb, high-fat diets, lipid ranges and heart problems. And so, regardless of this, there’s restricted knowledge on this relationship,” she mentioned.

The researchers in contrast the diets of 305 individuals consuming a LCHF food plan with about 1,200 individuals consuming a normal food plan, utilizing well being info from the UK database UK Biobank, which adopted individuals for no less than a decade.

The researchers discovered that individuals on the LCHF food plan had larger ranges of low-density lipoprotein, often known as LDL, ldl cholesterol and apolipoprotein B. Apolipoprotein B is a protein that coats LDL ldl cholesterol proteins and might predict coronary heart illness higher than elevated ranges of LDL ldl cholesterol can.

The researchers additionally seen that the LCHF food plan contributors’ whole fats consumption was larger in saturated fats and had double the consumption of animal sources (33%) in comparison with these within the management group (16%).

“After a mean of 11.8 years of follow-up – and after adjustment for different danger elements for coronary heart illness, equivalent to diabetes, hypertension, weight problems and smoking – individuals on an LCHF food plan had greater than two-times larger danger of getting a number of main cardiovascular occasions, equivalent to blockages within the arteries that wanted to be opened with stenting procedures, coronary heart assault, stroke and peripheral arterial illness,” researchers discovered, based on the information launch.

The researchers mentioned within the launch that their examine “can solely present an affiliation between the food plan and an elevated danger for main cardiac occasions, not a causal relationship,” as a result of it was an observational examine, however their findings are value additional examine, “particularly when roughly 1 in 5 Individuals report being on a low-carb, keto-like or full keto food plan.”

Iatan mentioned the examine’s limitations included measurement errors that happen when dietary assessments are self-reported, the examine’s small pattern measurement and that a lot of the contributors had been British and didn’t embrace different ethnic teams.

The examine additionally seemed on the longitudinal impact of following the food plan, whereas most individuals who observe a keto-like food plan are inclined to observe it intermittently for shorter durations of time.

A lot of the contributors – 73% – had been ladies, which Iatan mentioned is “fairly attention-grabbing to see, however it additionally helps the literature that’s accessible that girls generally are inclined to observe extra dietary patterns, are typically extra inquisitive about altering their life.”

When requested if there have been any teams that weren’t harmed by following a LCHF food plan, Iatan mentioned how lengthy individuals are on the food plan and whether or not or not they shed pounds “can counterbalance any LDL elevation.”

“What issues to recollect is that every affected person responds in another way. And so, there’s actually an inter-individual variability between the response. What we discovered is that, you recognize, on common, sufferers have a tendency to extend their LDL levels of cholesterol,” she mentioned.

Most well being consultants say the stylish keto food plan, which bans carbohydrates to make your physique burn fats for gas, cuts out wholesome meals equivalent to fruit, beans and legumes, and complete grains. Within the keto food plan, you restrict your consumption of carbohydrates to solely 20 to 50 a day – the decrease, the higher. To place that into perspective, a medium banana or apple is round 27 carbohydrates – the complete day’s allowance.

Keto is brief for ketosis, a metabolic state that happens when your liver begins to make use of saved fats to provide ketones for vitality. The liver is programmed to try this when your physique loses entry to its most popular gas – carbohydrates – and thinks it’s ravenous.

The keto food plan has been round because the Twenties, when a health care provider found it as a means of controlling seizures in kids with epilepsy who didn’t reply to different remedy strategies.

Low-carb diets like keto rely closely on fat to fill you up. Not less than 70% of the keto food plan might be made up of fats; some say it’s extra like 90%.

Whereas you will get all that fats from wholesome unsaturated fat equivalent to avocados, tofu, nuts, seeds and olive oil, the food plan additionally permits saturated fat like lard, butter and coconut oil, in addition to whole-fat milk, cheese and mayonnaise. Consuming a number of meals excessive in saturated fats will increase the physique’s manufacturing of LDL ldl cholesterol, which might construct up contained in the arteries and limit blood circulate to the center and mind.

Russia aims to be global leader in nuclear power plant construction

Russia aims to be global leader in nuclear power plant construction

Stay informed with free updates

Russia is building more than 10 nuclear units abroad as it looks to tap into rising energy demand driven by artificial intelligence and developing markets, according to an envoy of President Vladimir Putin.

Moscow is doubling down on efforts to boost its global influence by expanding its nuclear fleet, with plants under construction in countries including Bangladesh, China, Egypt, India, Iran and Turkey. Russia has enhanced its role as a major nuclear energy provider even as the oil and gas sector has faced heavy sanctions after its invasion of Ukraine.

Boris Titov, the Kremlin’s special representative for international co-operation in sustainability, said the country wanted to cement its position as “one of the biggest builders of new nuclear plants in the world”.

He said Russia expected strong demand for nuclear power from developing countries eager for cleaner sources of energy, as well as from technology companies harnessing AI in data centres. The International Atomic Energy Agency forecast this year that world nuclear generating capacity would increase by 155 per cent to 950 gigawatts by 2050.

“We are building more than 10 different units around the world,” Titov told the Financial Times. “We need a lot of energy. We will not be able to provide this energy without using . . . nuclear. We know that it’s safe . . . it’s not emitting [greenhouse gas emissions], so it is very clean.”

Russia’s growing overseas nuclear portfolio, including reactor construction, fuel provision and other services, spans 54 countries, according to an article published last year in the journal Nature Energy by the Norwegian Institute of International Affairs. 

Titov pointed to Hungary’s Paks 2 plant as well as units in Bangladesh and Turkey. Russia is also expected to build a plant with small modular reactors in Uzbekistan, while it signed an agreement with Burkina Faso’s ruling junta in 2023. The FT reported this year that Russia was involved in more than a third of new reactors being built worldwide.

Western governments have attempted to push back against Russia’s nuclear prominence, with the US banning imports of Russian-enriched uranium this May.

With the exception of Hungary, most eastern European countries have signed contracts for fuel developed to fit Soviet-era reactors by US company Westinghouse since the full-scale invasion of Ukraine. 

As part of a wider push to meet an indicative target of being free from Russian fuel imports by 2027, Dan Jørgensen, the new EU commissioner for energy, said that he wanted to examine the “full nuclear supply chain”. 

But Hungarian premier Viktor Orbán and Slovakian prime minister Robert Fico have said they would block any steps to restrict Russia’s civilian nuclear energy industry.

After meeting Putin on Sunday, Fico said in a post on Facebook that potential sanctions against Russia would be “financially damaging and endanger the production of electricity in nuclear power plants in Slovakia, which is unacceptable”.

But fears that Russia could create critical nuclear fuel shortages for the bloc, as it did for gas in 2022, are overstated, one senior EU official said.

“Rosatom has a vested interest to be reliable,” they added.

A more immediate problem is US sanctions on Gazprombank, a major conduit for energy payments to Russia. The measures exempted civil nuclear energy except for Hungary’s Paks 2 plant. Hungary’s foreign minister Péter Szijjártó has called the singling out of the new plant an “entirely political decision”.

Many developing countries are looking at nuclear to meet clean energy requirements, offering more potential markets for Russia.

Nik Nazmi Nik Ahmad, Malaysia’s natural resources and environmental sustainability minister, told the Financial Times that the country was “studying the introduction of nuclear”. 

He said all the “major players” were “talking to the [Malaysian] government” on potential projects, without referring to specific countries.

Speaking at the UN COP29 climate summit in Azerbaijan in November, Jake Levine, senior climate and energy director at the US National Security Council, said Washington was concerned about countries turning to China or Russia for nuclear power.

Global competitiveness in the industry was a “huge issue”, he added.

Why Trump's tariffs on Mexico would mean higher avocado prices at the grocery store

Of all the products that would be affected by President-elect Donald Trump’s proposed tariffs on Mexico, avocados stand out: 90% of avocados consumed in the U.S. are imported. And almost all of those imports come from Mexico.

Trump has said he plans to impose a blanket tariff of 25% on imports from Mexico and Canada, along with an additional 10% tax on goods from China.

It’s unclear whether the tariffs will be implemented or if they will serve merely as a negotiating tactic.

If enacted, they could have multiple effects on the avocado industry.

“Broad tariffs, like what’s being proposed, is not something that we’ve seen” before, says David Ortega, a food economist and professor at Michigan State University. “We had the trade war with China back in 2018 that affected steel and aluminum, but when it comes to food, these types of policy proposals are not something that are very common or that we’ve seen recently.”

With one of the biggest guacamole-eating events of the year — the Super Bowl — approaching in February, here’s what to know about avocados, tariffs, and why so many avocados are grown in Mexico.

Prices will rise

Avocados are displayed in a grocery store in Washington, D.C., on June 14, 2022. Experts predict avocado prices will rise in the event of tariffs on Mexican imports.

First, a 25% tariff on imports from Mexico would lead to higher avocado prices at the grocery store.

But estimating just how much higher is hard to say. It’s possible that producers and importers will absorb some of the costs to keep prices down and stay more competitive.

Ortega says there could be “pretty significant increases in the price of avocados. Maybe not the full 25%, but pretty close, given that there’s very little substitute ability with regards to where we would source avocados.”

But he cautions that because the tariffs apply only to the product’s value at the border, and not to other costs like transportation and distribution within the U.S., prices may not go up by the full 25%.

Regardless of these potential price increases, however, people in the U.S. love their avocados and they’re willing to pay more. Avocado consumption tripled in the U.S. between 2000 and 2021.

“Given that avocado is a staple of our consumption here, I would say that the elasticity is not very high, meaning that even with a big increase in price, consumption is not going to change that much,” says Luis Ribera, a professor and extension economist in the agricultural economics department at Texas A&M University.

Mexico is the biggest producer of avocados in the world and exported $3.3 billion worth of avocados in 2023. A study funded by the industry estimated that avocado production supports 78,000 permanent jobs and 310,000 seasonal jobs in Mexico.

“It’s a very important business in Mexico, very lucrative,” Ribera says.

Mexico emerged as the largest foreign supplier of fruits and vegetables to the U.S. for a few reasons, he says. One: Its proximity to the U.S. market. With a perishable product, closer is better. Peru is the second-largest source of foreign avocados in the U.S., but its greater distance means avocados need to be shipped farther.

The other reasons for Mexico are favorable weather that allows for year-round production of avocados and access to cheap labor, according to Ribera.

Avocados are grown in the U.S. too, mostly in California and to a lesser extent Florida and Hawaii, but U.S. growers can’t meet Americans’ big appetite. Avocado production in the U.S. has declined, even as Americans grew fonder of the green fruit, according to the USDA.

California avocado growers have faced droughts and wildfires in recent years, making it difficult to offer the year-round availability that American consumers crave, Ortega says. In addition, land is expensive and water is limited.

If the goal of implementing tariffs is to force avocado production to move somewhere besides Mexico, that isn’t easy.

It takes about eight years for avocado trees to produce fruit, according to the USDA. “This is not a product that you can just simply plant more of this season and you get more of in a few months,” Ortega says.

Other countries where the U.S. sources avocados — Peru, the Dominican Republic and Chile — “just simply don’t have the production capacity to replace Mexico’s supply,” he says.

Tariffs could impact the organic avocado market

Tariffs could also alter the market dynamic when it comes to organic vs. conventional foods.

If prices rise across the board, consumers who typically buy organic avocados might switch to conventional ones to save money. Organic produce makes up about 15% of total fruit and vegetable sales in the U.S., according to the Organic Trade Association, which represents hundreds of organic businesses and thousands of farmers.

“My hypothesis is that the price of conventional products would increase more than the premium organic product,” Ortega says. He reasons that because people who are used to buying organic avocados would move to buy conventional ones, “that in turn increases the demand and would make prices rise more for that category.”

Matthew Dillon, co-CEO of the Organic Trade Association, says those in the organic food industry are looking at diversifying their supply chains away from Mexico, but there’s a three-year transition period required for farmers to switch from producing conventional to organic produce.

“Supply chains are not incredibly elastic in organic. It takes more time to pivot and change when there’s a supply chain disruption. And tariffs are in some ways a form of supply chain disruption for a company, because it creates unpredictable pricing,” he says.

Together with grocery prices that have gone up more than 26% since the start of the COVID-19 pandemic, Trump’s plans for tariffs on Mexico, along with mass deportations, could create “a perfect storm of high inflationary pressure on the organic sector,” Dillon says.

Furthermore, retaliatory tariffs from Mexico could have their own impacts.

Aside from the threat of tariffs, the avocado industry has other challenges to deal with: climate change presents several problems, and avocados require a large amount of water to grow. Meanwhile, environmentalists say some avocado growers are cutting down forests to plant avocados.

Producers also face extortion from criminal gangs in Mexico.

And now with Trump’s tariff threats, producers are left to wonder about their next steps.

“Producers, they react to market fundamentals,” Ribera says. For example, people can foresee how bad weather in Mexico would affect avocado prices. Producers and retailers will adjust to higher and lower demand.

“The issue with a tariff is it’s not a market fundamental — it’s a policy. It’s a political move,” he says. “It could happen or it could not happen, or it could be increased or it could be decreased, you know. So it’s hard for the whole supply chain to adjust.”
