  • Chlorohydrin 3-MCPD in Bragg’s Liquid Aminos | NutritionFacts.org

    [ad_1]

    Chlorohydrin contaminates hydrolyzed vegetable protein products and refined oils.

    In 1978, chlorohydrins were found in protein hydrolysates. What does that mean? Proteins can be broken down into amino acids using a chemical process called hydrolysis, and free amino acids (like glutamate) can have taste-enhancing qualities. That’s how inexpensive soy sauce and seasonings like Bragg’s Liquid Aminos are made. This process requires high heat, high pressure, and hydrochloric acid to break apart the protein. The problem is that when any residual fat is exposed to these conditions, it can form toxic compounds called chlorohydrins, which are toxic at least to mice and rats.

    Chlorohydrins like 3-MCPD are considered “a worldwide problem of food chemistry,” but no long-term clinical studies on people have been reported to date. The concern is about the detrimental effects on the kidneys and fertility. In fact, there was a time 3-MCPD was considered as a potential male contraceptive because it could so affect sperm production, but research funding was withdrawn after “unacceptable side effects [were] observed in primates.” Researchers found flaccid testes in rats, which is what they were going for, but it caused neurological scars in monkeys.

    What do you do when there are no studies in humans? How do you set some kind of safety factor? It isn’t easy, but you can take the lowest observed adverse effect level (LOAEL) in animal studies, which, in this case, was kidney damage, add in some kind of fudge factor, and then arrive at an estimated tolerable daily intake (TDI). For 3-MCPD, this means that high-level consumers of soy sauce may exceed the limit. This was based on extraordinarily high contamination levels, though. Since that study, Europe introduced a regulatory limit of 20 parts per billion (ppb) of 3-MCPD in hydrolyzed vegetable protein products like liquid aminos and soy sauce. The U.S. standards are much laxer, though, setting a “guidance level” of up to 50 times more, 1,000 parts per billion.

    I called Bragg’s to see where it fell, and the good news is that it is doing an independent, third-party analysis of its liquid aminos for 3-MCPD. The bad news is that, despite my pleas that it be fully transparent, Bragg’s wouldn’t let me share the results with you. I have seen them, though, but I’m only allowed to confirm they comfortably meet the U.S. standards but fail to meet the European standards.

    This is just the start of the 3-MCPD story, though. A study in Italy tested individuals’ urine for 3-MCPD or its metabolites, and 100% of the people turned up positive, confirming that it’s “a widespread food contaminant.” But 100% of people aren’t consuming soy sauce or liquid aminos every day. Remember, the chemical results from a reaction with residual vegetable oil. When vegetable oil itself is refined, when it’s deodorized and bleached, those conditions also lead to the formation of 3-MCPD.

    Indeed, we’ve known for years that various foods are contaminated. In what kinds of foods have these kinds of chemicals been detected? Well, if they’re in oils and fats, then they’re in greasy foods made from them: margarine, baked goods, pastries, deep-fried foods, fatty snacks like potato and corn chips, as well as infant formula.

    The U.S. Food and Drug Administration’s limit for soy sauce is 1,000 ppb, but donuts can have more than 1,200 ppb, salami more than 1,500 ppb, ham nearly 3,000 ppb, and French fries in excess of 6,000 ppb, as seen here and at 4:03 in my video The Side Effects of 3-MCPD in Bragg’s Liquid Aminos.

    Most of us don’t have to worry about this problem, unless we’re consumers of fried food. Someone weighing about 150 pounds, for example, who eats 116 grams of donuts, would exceed the European Food Safety Authority’s TDI, even if those donuts were the person’s only source of exposure. That’s about two donuts, but the same limit-blowing amount of 3-MCPD could be found in only five French fries.

    Doctor’s Note

    Believe me, I pleaded with the Bragg’s folks over and over. It’s curious to me that Bragg’s allowed me to talk about where its level of 3-MCPD fell compared to the standards but not say the number itself. At least it’s doing third-party testing.

  • Inflation is easing, but the prices of these groceries are expected to soar in 2023 — including one whose price rose nearly 60% in December

    Inflation is easing, but the prices of these groceries are expected to soar in 2023 — including one whose price rose nearly 60% in December

    General inflation is easing, but the prices of some food items are not going down anytime soon. And the reasons are largely out of the Federal Reserve’s control.

    The consumer price index cooled in December, falling to an annualized 6.5% from the 7.1% annual rate recorded in November, according to government data. Still, the annualized inflation rate in food was 10.4% in December, significantly higher than the overall inflation rate even as it represented a slower rate of increase than November, when food prices were 12% higher than in November 2021.

    Inflation running at nearly 40-year highs over the past year has put a squeeze on American wallets. Through a series of jumbo rate hikes, the Federal Reserve has sought to tamp down inflation. Its target interest rate was lifted from a negligible level to a range of 4.25% to 4.50% by the end of 2022.

    But a few factors impacting food prices are not going away. War is still ongoing in Ukraine, which affected the prices of fertilizers and animal feeds; the avian flu continues to impact the egg supply; and extreme weather conditions are adding complexities to food production. 

    The following is a look at how a few popular food items are affected.

    Eggs

    The price of eggs surged 59.9% on the year in December, up from 49% in November, according to the most government data. That means a carton of Grade A large eggs on average more than doubled in cost with prices reaching $4.25 in December 2022, compared to $1.79 a year earlier. In some parts of the country, consumers could pay up to $8 for a carton of organic eggs. 

    Avian flu, which has forced millions of chickens to be culled and caused a shortage of eggs, is the main reason behind the price increase. In a change from previous breakouts that faded as summer ended, this time the avian flu lingered into winter. 

    The holiday season is usually the peak for consumer egg demand, which means that we could see egg prices tick down a little in the new year, experts said. 

    But it will not be a significant drop given the ongoing flu and high cost of feed. If input costs continue to increase and the bird flu continues to kill large quantities of hens, the costs will most likely be passed on to consumers, said Curt Covington, senior director of partner relations at AgAmerica Lending, a financial services company providing agriculture loans. 

    Experts, including the biggest egg producer in the country, Cal-Maine, said the avian flu will be hitting egg supplies for the long term. “More than 43 million of the 58 million birds slaughtered over the past year to control the virus have been egg-laying chickens, including some farms with more than a million birds apiece in major egg-producing states like Iowa,” the Associated Press reported this week.

    “I suspect it will take much additional effort to ‘stamp-out’ HPAI this time around and we may very well be dealing with the reality that this will be a year-round issue,” said Brian Earnest, lead economist for animal protein at CoBank, a national cooperative bank serving industries across rural America, in an email to MarketWatch. 

    The weekly supplies of eggs on hand has also reached a historic low, he told MarketWatch. For the week ended Dec. 19, cases on hand reported by the USDA totaled 1.176 million. That’s a 20% drop year-over-year, and the lowest level for the same week since 2014, he said.

    Butter

    Butter prices rose by 31.4% on the year in December, up from 27% in November, making the average price for a pound of butter $4.81 nationally. It was $3.47 a year earlier. 

    Extreme heat and smaller cow herds are the main reasons behind that, experts told MarketWatch. Cows eat less and produce less milk in the heat, and the cost of maintaining milk production skyrocketed last year, making farmers unwilling to expand their herds. 

    Going forward into 2023, the price of butter could soften, but year-over-year price increases could still stay high, said Tanner Ehmke, lead economist of dairy and specialty crops at CoBank. 

    Cows are approaching their prime milk-producing season, which usually runs from March through May, although customer demand usually peaks during the recently completed holiday season, he said.

    But the increase of supply will not be much, Ehmke said, because costs are staying at record highs for farmers to maintain and expand their herds. Drought in the Western part of the country and the war in Ukraine continue to impact the supply and costs of feed. 

    “It’s [going to be] a very modest increase,” said Ehmke. 

    About 58% of the U.S. is at least “abnormally dry,” according to the National Integrated Drought Information System. It’s likely this year will see more drought-inducing La Niña weather conditions, according to National Weather Service’s Climate Prediction Center.

    “If so, the third dry year in a row would signal the worst drought since at least 2011- 2013,” said Rob Fox, director of CoBank’s knowledge-exchange division in a 2023 preview released in December. “But this time it is more concentrated in the Western states, and it would be even more devastating to their already precarious water supplies and desiccated pastures,” he added.

    At the same time, butter production is competing with the growing production of and appetite for cheese in the U.S., Ehmke told MarketWatch last September. U.S. cheese consumption per capita is growing around 1% to 2% each year, according to the USDA. U.S. cheese exports also increased, particularly to countries like South Korea and Japan.

    Vegetable oil and margarine

    Margarine, which is largely made of vegetable oil, is also seeing a huge price increase. The price of margarine, the substitute for butter in the old days, rose by 43.8 % in December, down slightly from 47.4% in November compared to a year before. 

    While soybeans, corn and sunflower oil are among the food items that have been hugely impacted by the war in Ukraine, another dynamic is at play here, analysts suggested: A large quantity of vegetable oil is being used for the production of renewable diesel.

    In 2021/2022, 38.4% of soybean-oil supplies were used for biofuel production — biofuel is a broader category than renewable diesel — up from 35.6% the year before, according to USDA data updated in October 2022. 

    Transitioning to a green economy laid out in the Inflation Reduction Act will require more soybean supply. The expected growth in soybean oil-based renewable diesel will require considerably more soybean bushels for domestic production, wrote Kenneth Scott Zuckerberg, CoBank’s lead economist for grain and farm supply, in a report in September. 

    At the moment, global grain and oilseed supplies are tight, and the combined global stocks of corn, wheat and soybeans are forecast to decline for the fifth straight year in 2023, according to the CoBank report.
