Lucky Australians: Sandro Demaio’s The Doctor’s Diet

Sandro Demaio.  The Doctor’s Diet.  Pan Macmillan Australia, 2018.

Image result for doctors diet

I don’t usually say anything about diet books or cookbooks, and this is both, but Demaio is someone I know, the book is worth reading for its food systems approach to eating, and the proceeds go to charity:

Author royalties from the sale of this book will go to th Sandro Demaio Foundation to fund public health and nutrition projects across Australia.

What I like about the book is his straightforward, tell-it-like-it-is commentary on today’s food environment.  Here’s what he says about snacks, for example.

A concept invented in the 20th century by the food industry simply to get us to eat more food and boost sales, snacking isn’t a natural part of a healthy diet,  Snacking between meals is a major source of unwanted sugars, additives and calories for adults and kids alike…Avoiding snacks will improve your appetite for your next meal.

The book is full of tips for navigating the hazards of ubiquitous food marketing and his invitation to “come cook with me” demands a yes.  

The book reminds me a lot of Sam Kass’s terrific Eat a Little Better.

Let’s hope there’s a U.S. edition soon (although he tells me it can be ordered here).

Rice cereals for infants: the arsenic problem

I’ve been collecting items on concerns about the levels of arsenic in rice, especially rice cereals for children.

The arsenic problem

Arsenic is toxic.  It occurs in food and water in two forms:

Inorganic: a carcinogen and heart disease risk factor

Organic: less toxic, but still harmful

Infant rice cereals are a special concern because they are often the only cereals fed to infants, and arsenic adversely affects infant cognitive development.

How much arsenic is in rice cereal?

In January 2012, Consumer Reports found worrisome levels of arsenic in apple and grape juices.  It followed this with a November 2012 testing of more than 200 products which found measurable amounts of arsenic in every product category, and in both forms:

Further testing in 2014 confirmed these findings.  Because there is no safe level of arsenic, it’s best not to have any, let alone the amounts found in commonly consumed products.

But in March this year, a report from Healthy Babies/Bright Futures (HBBF) found six times more arsenic in infant rice cereal than in infant cereals made from other grains.

How does arsenic get into rice?

Soil and water naturally contain arsenic, but humans also add arsenic to soil through agricultural pesticides (now supposedly banned) and other sources.

Rice also absorbs more arsenic from soil and water than other grains, perhaps because arsenic resembles the silicon these plants need, but also because rice fields are often flooded to prevent weed growth.

What is being done about arsenic in rice cereal?

In 2016, the FDA proposed limits on arsenic in infant rice cereals, issued a call for public comments, and extended the comment period, but has yet to take action.

The agency’s web page on rice an rice products provides:

In March this year, the Government Accountability Office issued a report urging FDA to finalize its guidance (this provides an excellent and well referenced review of the arsenic-in-cereals situation).

The FDA has all the evidence it needs and it is difficult to understand what is holding up its action.  One can only assume politics, alas.

What should you do in the meantime?

It seems pretty obvious that infant rice cereals should be removed from the market unless they can show much lower arsenic levels.

Plenty of other cereals exist.  At this point, those are much better options.

Weekend reading: Elliot Coleman’s New Organic Grower

Elliot Coleman.  The New Organic Grower: A Master’s Manual of Tools and Techniques for the Home and Market Gardener.  30th Anniversary Edition.  Chelsea Green, 2018.

The first edition of this book came out in 1989 and it has been an essential tool for organic farmers and home gardeneres ever since.  Coleman’s goal is to make everyone want to farm organically.

“Small farms,” he begins, “are where agricultural advances are nurtured.”  And, he says, “I write only about those things I know.”

Fortunately, he knows a lot.  He knows about soil fertility, pests, weeds, crop rotations, agricultural craftsmanship, land, labor, marketing, and the economics of all of this.

His philosophy?  A pleasure to read.

Humans cannot imagine a world where they are not in charge.  As a biological farmer, I work in partnership with Nature, and I’m a very junior partner.  Given the limited amount of hard knowledge available, I often refer to my management style as “competent ignorance,” and I find that a very apt description.  But my level of trust in the design of the natural world and willingness to be guided by it is discomforting to those who think we should exercise total power over Nature…The reality of today’s world is that the practical success of the many farms managed on biological lines coexists with the striking lack of interest (antagonism actually) from scientific agriculture in exploring why these farms succeed.  The foundation upon which our Maine farm operates—a sense that the systems of the natural world offer elegantly designed patterns worth following—appears to be an indecipherable foreign language to most of agricultural science.

How did glyphosate get into Cheerios?

The Environmental Working Group recently released a report on the amounts of glyphosate (Roundup) in children’s breakfast cereals, particularly those made with oats and wheat.

Roundup, you may recall, has been judged a probable carcinogen by the International Agency on Research on Cancer (IARC) and California courts.  It is used to kill weeds in fields growing crops genetically modified to resist Roundup.

But oats and wheat grown in the U.S. are not genetically modified.  The FDA’s list of genetically modified foods says nothing about oats and wheat, and the agency does not permit GMO versions to be marketed.

How could Cheerios and Quaker Oats be contaminated with glyphosate at amounts that exceed standards?

The explanation:

Increasingly, glyphosate is also sprayed just before harvest on wheat, barley, oats and beans that are not genetically engineered. Glyphosate kills the crop, drying it out so that it can be harvested sooner than if the plant were allowed to die naturally.

Really?  They spray glyphosate on oats just before harvest?  Yes, they do.

What this means is that more glyphosate gets into your food from the non-GMO wheat and oats sprayed just before harvest, then from GMO corn and soybeans sprayed earlier in their growth.

Whether eating glyphosate is bad for you or your kids is a matter of fierce debate.  As the New York Times explains, the safety of glyphosate is very much at issue:

In fact, it is central to a raging international debate about the chemical that has spawned thousands of lawsuits, allegations of faulty research supporting and opposing the chemical and a vigorous defense of the herbicide from Monsanto, the company that helped develop it 40 years ago and helped turn it into the most popular weedkiller in the world.

Scott Partridge, a vice president at Monsanto, said in an interview on Wednesday that hundreds of studies had validated the safety of glyphosate and that it doesn’t cause cancer. He called the Environmental Working Group an activist group.

“They have an agenda,” he said. “They are fear mongering. They distort science.”

The EWG states its advocacy position on its website:

The Environmental Working Group’s mission is to empower people to live healthier lives in a healthier environment. With breakthrough research and education, we drive consumer choice and civic action. We are a non-profit, non-partisan organization dedicated to protecting human health and the environment.

I do not view this report as distorting science.  If anything, it provides data that the industry is not collecting or does not want released.  This information is useful for making decisions about what to eat.

You don’t want your kids eating glyphosate while scientists are still in disagreement about the extent of its harm to human health?

  • Vote with your fork: Buy organic cereals; they have far less or no detectable glyphosate.
  • Vote with your vote: Call for policies to get these practices stopped.

Or you can consider a third option now in play: file a lawsuit.

Burning question: are almond and soy “milks” milk?

Scott Gottlieb, Commissioner of the FDA, says his agency will take up the vexing question of what to call “milks” made from soy, almonds, and other legumes and nuts.

If you look at our standards of identity, there is a reference … to a lactating animal,” Gottlieb said during an interview at the POLITICO Pro Summit. “An almond doesn’t lactate, I will confess. So the question becomes, ‘Have we been enforcing the standard of identity?’ And the answer is probably not.”

The dairy industry does not want these products called “milk” (see discussion of the “war over soy milk,” in the New Republic).  It argues that they do not meet the standard of identity for milk, but also that they are less nutritious.

The Good Food Institute, which promotes plant-based meat, dairy and egg substitutes, petitioned FDA to set some rules for this.  Its view is that manufacturers of dairy alternatives have a First Amendment right to describe their products as they like (also see the Institute’s letter to the FDA).

Gottlieb says the FDA will soon open the question up for public comment.

If these products cannot be called milk, what can they be called?  On this, I defer to The Onion.

As for whether almond milk is milk, here is the ingredient list for the Almond Breeze product:

ALMONDMILK (FILTERED WATER, ALMONDS), CALCIUM CARBONATE, SEA SALT, POTASSIUM CITRATE, SUNFLOWER LECITHIN, GELLAN GUM, NATURAL FLAVORS, VITAMIN A PALMITATE, VITAMIN D2, D-ALPHA-TOCOPHEROL (NATURAL VITAMIN E).

Salmonella in Honey Smacks cereal?

I guess I shouldn’t be surprised.  The latest source of Salmonella is a kids’ cereal, Kellogg’s Honey Smacks.  They may be a good source of vitamin D, but watch out!

This is no joke.  The CDC reports the damage: 73 cases in 31 states, with 24 hospitalizations.

The CDC says you should not eat this cereal.  Period.  You should especially not eat this if its used-by date ranges from June 14, 2018 to June 14, 2019.  Kellogg has recalled packages with this used-by date.

I took this photo on June 16 at Wegmans in Ithaca.  I was surprised to see them on the shelf, but their use-by date was May 19, 2019 so Wegmans must think they are OK.  Even if I habitually bought sugary kids cereals, I’d pick another one until this outbreak is over and gets an all-clear signal.

Recent Salmonella outbreaks have involved pre-cut melon, eggs, dried coconut, pre-made salads, and sprouts.  Food safety lawyer Bill Marler says don’t eat them either.

Outbreaks caused by contamination of commercial boxed products are rare.  Bacteria don’t grow well in dried foods.  The CDC doesn’t discuss how the Salmonella got into the package.

Could honey be the source?  Honey is not sterile, but bacteria don’t grow in it very well (not enough water).

This reminds me of the situation with dry pet foods and treats.  Canned pet foods have been cooked and are sterile until they are opened.

Dry foods are not sterile.  Although the extrusion process heats them enough to kill bacteria, flavors and other additives are sprayed on before they are packaged.  Contamination with Salmonella and other pathogens is a constant problem (Mal Nesheim and I discuss this in our book about the pet food industry, Feed Your Pet Right).

I will be interested to see if Kellogg can find the source of the contamination.

Question for the day: Is Tofu processed?

With all of the talk these days about avoiding ultraprocessed foods, questions come up about what that means.  After I posted about the added colors involved in processing plant-based meats, I received a tweeted question:

This got me thinking about tofu. Is it highly processed? Love your thoughts on it!

Like everything else about nutrition, the answer depends—in this case about what you consider processing.  All foods are processed to some extent, if you count washing and cutting.

Ultraprocessing, however, refers to foods that look nothing like what they started out as, and are loaded with added sugars, salt, and artificial colors and flavors.

Commercial tofu is minimally processed; it is just soybeans and a coagulating agent.  Here is one recipe, for example:

  • Soak the soybeans: in water to soften them for 12 to 14 hours.
  • Process the beans to a slurry.
  • Boil the slurry to inactivate lectins and other undesirable soy compounds.
  • Extract the soy liquid (“milk”) with a roller press to separate it from the soybean pulp.
  • Mix a coagulating agent—calcium sulfate, magnesium chloride, or nigari.—into the soy milk.
  • Press the liquid out of the curds.

The tofu you might make at home seems minimally processed, as it is made from just commercial soymilk and lemon juice.  Commercial soymilk, however, contains far more than just soybean liquid:

INGREDIENTS: Soymilk (Filtered Water, Soybeans), Cane Sugar, Contains 2% or less of: Vitamin and Mineral Blend (Tricalcium Phosphate, Calcium Carbonate, Vitamin A Palmitate, Vitamin D2, Riboflavin [B2], Vitamin B12), Sea Salt, Natural Flavor, Gellan Gum.

I consider good-quality commercial tofu to be minimally processed.  Commercial soymilk is another matter.  Sugar is its second ingredient.  Gellan Gum is its last ingredient.

I wasn’t familiar with Gellan Gum, but I love the Wikipedia definition: “a water-soluble anionic polysaccharide produced by the bacterium Sphingomonas elodea (formerly Pseudomonas elodea),” that substitutes for agar and carrageenan.

A 1988 study of its effects on humans concluded that “the ingestion of gellan gum at a high level for 23 days caused no adverse dietary or physiological effects in any of the volunteers.”  No surprise here: Financial support for the study came from Kelco, Inc., a company that supplies Gellan Gum.

If you want your tofu unsweetened and minimally processed, buy a freshly made commercial variety.
