Food for Health Part 3 Superfood (2/2)

This the final post on food for health. I'm moving on to water next. Just a reminder, these are my own thoughts and ideas. None of these should be eaten to excess. If something catches your interest do your own research. If you have a better understanding or can add clarity to the discussion please chip in. 

 

1) The chlorophyll alone would earn Leafy Greens a place on this list. (If you haven’t seen the short video clip Scotlyn linked in the comments of last post check it out.) But chlorophyll is extremely fragile and leaves are packed with antioxidants to protect it. When it breaks down the green fades and you can see the yellow or red  pigments underneath. 

The ratio of surface area to volume tracks the nutritional value of foods very well. Kale is more nutritious than broccoli for example (apparently broccoli leaves are the most nutritious part!) Eat them fresh or lightly cooked. Light cooking can make some leafy greens more digestible and some nutrients more bioavailable. Avoid overcooking, when veggies go grey the chlorophyll has broken down and you’ve lost the antioxidants too.

 

2) Kale usually tops the list of nutrient dense veggies. Like parsley and nettle, it’s a great antidote to a SAD diet. The whole Cabbage Family is a powerhouse of nutrition that goes far beyond the green. The white in cabbage and cauliflower is another antioxidant flavonoid, more stable and with similar benefits to the other colours. 

The cabbage family contains a group of powerful anti-cancer chemicals called sulforaphanes. Sulforphanes, like other anti-oxidants, are part of the plant’s defence mechanisms. They are the source of that distinctive cabbage odour and they are activated and released when the plant is damaged. Chopping, chewing, or massaging (as is done for kale salads) is needed to get them going. Sulforaphane is also easily damaged by overcooking but is remarkably stable in ferments.   

 

3) Garlic, discussed last time, is the most potent of the Alliums and the other members of that family, onions, leeks, shallots, and chives, all share some of the same medicinal properties. Allicin, that distinctive onion scent and infamous tear-jerker, and it’s metabolites, are sulphur based molecules. Antioxidant, anticancer, and anti microbial, garlic also supports both heart and brain health.

 

4) I covered Mushrooms in part 2 of this series. Here I will just say that studies of health outcomes for people who work in mushroom production in Japan (and presumably eat more than average amounts of mushrooms) have confirmed the health benefits of the many kinds of mushroom popular there. Unfortunately, there are no studies of the button mushrooms and portabellos popular here.  Unlike veggies, mushrooms benefit from being well cooked with some sources recommending cooking them in both fat and water.

 

5) Oil rich Nuts and Seeds are top sources of fat soluble vitamins and anti-oxidants. Sunflower seeds top the list for Vitamin E; Brazil nuts are number one for selenium. Selenium is a precursor to glutathione the primary antioxidant our bodies produce. 

Nuts and seeds also contain lipid micronutrients called phytosterols that have immune modulating properties. They calm down overactive immune systems. Extracts of beta-sitosterol,  from sunflower seeds, are used therapeutically for auto-immune conditions.

Nuts and seeds are best eaten whole and fresh. They go rancid quickly once their antioxidants are depleted. Apparently our tastebuds can detect rancidity levels as low as 2%; an indication of how bad rancid fats are for us. Seed oils can go rancid in our bodies if we don’t have the antioxidants to protect them. Flaxseed, hempseed and walnuts are the most fragile as they have the highest content of desirable polyunsaturated fats. 

 

6) Cold Water Fish and Seafood contain another kind of polyunsaturated fat that is essential for heart and brain and a myriad of other things. Deficiencies of “essential” nutrients will have an impact on all kinds of body functions. They are also packed with antioxidants to protect those fragile fats. The pink in salmon (and flamingos) is a carotenoid derived from krill and other plankton that need the polyunsaturated oils to function in cold water and a way of protecting from sun damage.

 

7) Fermented foods are hugely popular these days and for once I’m all in with promoting the trend. Fermentation is the only food preservation method that increases the nutritional value of food. Every other technique involves some loss of nutrients. Ferments add probiotics and enzymes; they make fibre more digestible and they release nutrients that would otherwise require long chewing or long cooking. Regular consumption of fermented foods increases the proliferation of gut flora; your best defence from ingested pathogens. A strong intestinal microbiome is a key support for strong immune function.

Fermented foods are good for digestion; they are anti-inflammatory; anti-toxin; anti-cancer. The strong flavours may be unappealing to some but the value to your body is so great that, given the chance, your tastebuds will  adjust.

 

8) As well as the flavonoids that give them colour, organically grown grapes produce anti-fungals on their skin which have specific anticancer properties. Commercial growers use carcinogenic anti fungal sprays that eliminate the need to produce these protective chemicals. Grape seeds, crushed in your molars when you eat grapes, are the primary food source of the immunity enhancing anti-cancer flavonoid resveratrol. Grape seed oil, often recommended for high temperature frying, has a high smoke point because it is so rich in antioxidants. The oil doesn’t burn until they’ve been destroyed.

 

9) Brown Rice is similar to the rice that was available before the advent of mechanical polishing. In addition to the insoluble fibre which feeds the intestinal flora and has a critical function in scouring the lower bowel, rice bran provides several of the  B-vitamins and contains a substance called gamma oryzonol which has a myriad of health benefits including immune support . 

Other whole grains also have some of these benefits. Oats, either whole, steel cut, or slow cooking rolled oats, has many similar benefits as well as specific benefit for heart health and weight management. But grinding grains into flour changes the picture considerably. Even quick cooked oats don’t seem to deliver the same results. Finely ground flours go stale (or rancid in the case of an oil rich grain like oats) quickly and the fast absorption of easily digested carbs can play havoc with blood sugar levels leading to food cravings and binge eating.

 

10) Bone Broth is specific for boosting immune function. The quasi-mystical reputation of chicken soup for colds and flu is well deserved. Immune cells are produced in bone marrow. Broken bone broth is easy to make and well worth the effort especially if you are paying the premium for free-range or pasture raised animals products. (Save the fat too, every scrap has value). Freeze the bones with vegetable scraps (except cabbage family) until there are enough to make a pot of stock or add the bones directly to long cooking soup, stew, and chilli.  Soup bones are often available at a very reasonable price from local meat producers or butchers.

 

More could be said about all of these and many more could be added to the list. But I’m stopping here. I will end with a saying from traditional Chinese medicine from the book “Healing with Whole Foods” by Paul Pitchford: “Taking medicine when you become sick is like planting a garden when you get hungry.” 

 

That’s it. Eat, enjoy, stay well.

Excellent as usual. Many of these are growing in my garden (brassicas and alliums, for sure). Also hazelnuts are native and self-planting around here.

Bone broth is something I find myself recommending a lot. It is very deeply hydrating to the tissues, fantastic "medicine" if one is healing from injury, and generally good eating. :)

There are two rather concentrated "superfoods" that I have recently found myself adding to my own menu. One is marmite, or yeast extract, which, I suppose counts as a fermented food. An excellent source of b vitamins. The other is organic molasses (the real "leftovers" from the sugar refinement process), which is high in magnesium and in potassium (which helps balance salt intake).

FWIW. :)

Marmite - on toast - even my 4 year old is a fan (perhaps being half English helps!). It's also good in gravy, sauces generally.

how are you using the molasses?

Ah, thank you, Claire. That's why I was asking; it's super strong.

Glad I found your site.

In many lists of nutrient-density of vegetables, one of the top spots is beet greens. Lots of people don't even realize they're edible, but my parents cooked them often and I've always loved them. Chard is way up there as well.

Fascinating series. Thank you.

That fact about the surface area to volume ratio is nice. I had only heard about it in relation to the dimensions of organisms without alimentary or nutrient transport vessel systems. It probably pertains to all sorts of other situations.

And not to be obtuse, but you don't cook any cruciforms in your stock, right? But it's ok to put them in soup/casserole right at the end just long enough for them to cook? I suppose that means cabbage stew is out. Colcannon?

Agreed with most everything you've written here, Claire. One thought regarding fish and seafood, there's so much pollution now in the oceans that trying to find something that's not full of mercury, or PFAS, or plastic, is rather a challenge. I spent an hour or 2 recently looking into this and found a blog somewhere where the writer lamented over this, and went on to say that as far as she'd been able to find, herring was the least poisoned of the salt water fish, and that fresh water fish was generally so poisoned that she avoided it.

Regarding fermented foods, I've recently tried making pickled onions as a simple salt preserve; onions, 3% salt, whatever else you want to throw in (I tried fresh turmeric root and pepper corns), and it is most splendid. As with everything else, a jar of home-made pickled onions is about a 1000 times nicer than a jar of shop-bought pickled onions, and very simple indeed to make.

You mention sulforphane and the crucifer family; sprouted brocolli seeds contain the highest quantity of this - "Broccoli sprouts are 20 to 50 times richer in sulforaphane than fully grown broccoli crowns" - this link goes into some detail about to maximize the levels:

I'm guessing you already know about bentonite clay as a detoxing agent, I use montmorillonite clay as it's very similar (and montmorillon is not actually that far from where I am as some added entertaining coincidence), and I'm guessing you know about Berkey water filters. I looked into water filters a couple of years ago and they were literally the only company that actually had their filters tested by a third party and published the results. Unfortunately I think they are unavailable now as big pharma had them shut down recently.

A low tech water filter that was new to me recently:

https://www.youtube.com/watch?v=nSBwJNDDUfc

"...a research article from MIT (link below) that showed the xylem tissue of gymnosperms effectively filtered out all bacteria from contaminated water. In this video I set up a filter using those findings but also, using a never before seen method using grape vines as both a siphon and filter in one. A lab analysis confirmed the presence of e. coli bacteria in the water to be filtered. The water that passed through the grape vines had no detectable e. coli bacteri"

https://news.mit.edu/2021/filters-sapwood-purify-water-0325

essentially it's using a tree branch as a filter ("the interiors of nonflowering trees such as pine and ginkgo contain sapwood lined with straw-like conduits known as xylem, which draw water up through a tree’s trunk and branches. Xylem conduits are interconnected via thin membranes that act as natural sieves, filtering out bubbles from water and sap.")

I think I know which experimental historian you're talking about, as I'm a huge fan of Ruth Goodman's work. If I'm correct on that guess, "Tales from the green valley" is my favourite, though we've watched every series she's done at least twice!

Regarding the geophagy (earth eating), I just crush up a teaspoon or 2 of clay in a mortar and pestle, scatter that powder in some porridge and then just eat the porridge. Maybe a couple of times a month, same for my dog. I did try drinking it too, but the porridge version is very quick and easy and makes no difference to the taste of my breakfast, whereas the clay in water was a bit more challenging to get down. The porridge, even my 4 year old doesn't mind (I used to add a bit to the bread I make, but he did complain about that as it does have a slightly gritty edge sometimes).

sorry for the late reply. i buy the clay from a local health food store.

If you like dairy in general, fermented milk - kefir - is a good way to start on fermented foods. I can find it in supermarkets here (quite surprisingly, as my local supermarket had no idea what tofu was when I first asked about that - we're quite rural France here), and it's possible to make your own kefir using shop-bought stuff as a starter for a couple of rounds. You do need the kefir grains if you're going to drink kefir regularly, as the shop-bought, back-slopped (technical term!) version starts to get sour after 2 or 3 rounds, but it's a good way to give it a try initially. I love kefir at this stage, I drink it most days; even if I get lazy and it goes bad, you're left with whey (useful for fermenting other stuff) and basically cream cheese...I've mixed that once with pickled onions for a really yummy cheese on toast type spread.

Sour cream made from kefir sounds excellent, I'll give it a try.

Quark, no, I've never even heard of it before now. I've been reading recently that store-bought yogurt, while still good as it's a fermented food, contains much less benefit than yogurt that has been home-made, which I can well believe, given that everything from the shops is pasteurised. I've been meaning to try making my own yogurt and I've got 2 reasons now, as I'm curious to try quark.
