Invasive Plants 5 - Crab Grass
November 1, 2011
Writing about the possible benefits of invasive plants, I had the fear that for most broad-leafed weeds it would be easy to find medicinal and other value, but that for grasses, I might have to pass. Interestingly, grasses have some good sides, too – even a such-maligned, horrible weed as crab grass.
Crab grass (also called “finger grass” because of its spiky inflorescences, or “fonio”, for African plants) are actually several Digitaria species – “Digitaria” again meaning “finger-like”.
Why is crab grass the proverbial weed? It turns out that “crabs” can’t take hold in a well-watered, well-fertilized lawn. But let that lawn be neglected, and develop some bald spots – that’s where the annual crab grass will move in, taking advantage.
A lawn usually consists of perennial grasses that stay green long into fall and often into winter. Crab grass would be fine to be intermingled, if it would not die by the end of summer and will leave a bald spot – especially if you pull it and do not immediately reseed with normal lawn seed. In that bald spot, its many, many seeds can take hold again. Crab grass’ trick is its long germination period: It might die early, but it can germinate basically all year, as long as there is no snow on the ground. Usually, a bald crab grass spot extends thus from season to season, always looking awful in the fall, showing your neighbors that you are a less-than-perfect gardener.
Remedy? Keep your grass healthy, well-fed, well-watered, well-limed, and reseed in fall and spring, so that crab grass seedlings have no chance.
So, what for is this invasive grass good? For cows and other ungulates like deer crab grass is as nutritious as any other grass; even more so, because of its high protein contents. Sub-Saharan Africa people eat the milled crab grass seeds in porridge and bread. The problem with crab grass is that it germinates and ripens its seed willfully throughout the year. Therefore it must be hand-harvested, defying large-scale cultivation. However, early settlers in America purposefully would till a spot in the spring so that crab grass could grow there, for the grazing of the animals later in the year.
Crab grass (like Bermuda grass) is a warm-weather grass. As such, it accumulates less sugar than a perennial grass - it does not intend to stay around for the winter, needing staying power through the winter. That makes crab grass better digestible especially to horses who might be quite sensitive to a high sugar and starch content – which bloats them, causing colic. So, as hay, crab grass is quite desirable.
Crab grass contains non-trivial amounts of magnesium, phosphorus and calcium – important for bone health, and some vitamin A, folate, and retinol; they might account for its use in eye health: Medicinally, crabgrass infusion is said to be helping against cataracts and feebleness. I probably won’t use it exactly for that purpose. But just knowing that crab grass is not poisonous will land it in my garden teas from now on. Read More

The French Paradox
May 20, 2011
We arrived in Paris on Sebastian Kneipp’s birthday – on the 17th of May and celebrated with a glass of wine. And a lunch consisting of three courses: Onion soup (minus the cheese and the bread), escargots (snails) in garlic, crème brulée. Not terribly healthy – but delicious.
Writing from Paris, of course, I want to talk about the French Paradox.
French people eat more fat (think triple brie and foie gras!), drink more wine (think a smooth Bordeaux!) and smoke more than their US counterparts (think Gauloises!), yet they die less of cardiovascular disease. American scientists dubbed this puzzle the French Paradox – and they have come up with some tentative explanations:
• The French surely are underreporting their cardiac deaths
• The French have their main meal at midday and take more time for it
• The French prefer wine over beer; wine contains healthy resveratrol
• The French don’t snack
• The French eat less trans-fats (frying)
• The French eat less hydrogenated fats (margarine, processed food)
• Perhaps saturated fats are not as bad as we thought
• The French eat less sugar, less HFCS, less white starches
• The French cigarette tobacco is not as adulterated American tobacco
• The whole study might be wrong
American scientists looked for the fat contents, the carbohydrates, the proteins to come up with an answer, missing the big, simple picture: fresh foods. Fresh food contains life-giving molecules beside the three biggies (fats, carbs, proteins). Those molecules are miniscule in weight, but hugely important in how they support health. We are from Nature, and throughout Evolution, we ate whole foods. Only modern “food” production has done away with Nature’s wisdom.
The three biggies were important when people were starving – if you don’t get fat and the other two, all the best polyphenols and anti-oxidants and other small plant molecules will not keep you alive. But now that we have plenty of food (which is a first in history – but don’t forget it is not yet true for every single person in the world), we need to turn to quality of food. Which needs we need to return to real food – the food Nature intends us to eat. And not to make it too difficult: It is mostly vegetables we need to bring back on our tables.
The French are eating real food; Americans are eating plastics masquerading as food. Don’t get me wrong – junk food is inching its way also into the French society. But overall, the French still go to the open market to buy fresh produce and freshly slaughtered chickens and fish. Except for the last item on the list, all the factors may play a role. But the main thing is the freshness of the food. The quality lies in fresh things, grown things – not concocted in the lab and manufactured in bulk.
And by the way, their cigarettes might be a tad healthier – but please don’t start your French new life with Gauloises! Read More

National Celiac Disease Awareness Day September 13th
September 21, 2010
National Celiac Disease Awareness Day September 13th
Because we were traveling that day in Persepolis/Iran, I missed the date that reminded us of the most under-diagnosed disease there is: Gluten intolerance.
Sprue, celiac sprue, celiac disease, gluten intolerance – they are all different names for the same disease – the one that turns your daily bread into poison.
Inventing agriculture some five to ten thousand years ago was a huge step forward for mankind: Less people - especially children - starved, more survived – and more people had the leisure to turn to cultural endeavors (observing the stars, building cities, learning poetry). Agriculture is at the heart of our civilization.
Of course, there was a price to pay: Some children could not tolerate the new foodstuffs on the table – milk and bread – and died. But most did very well. The population grew.
Nature whispers to hunters and gatherers in the voice of the wind, the rustling of leaves, the babbling of brooks – everywhere spirits and gods seems to reside in holy nature places.
Once farming has been invented, there’s really need only for a single God – the one who lets the wheat grow and fattens the cows so that they give milk: Give us our daily bread was the prayer ever since then. Leaving Nature behind and turning to monotheism also meant to exploit Earth and go for effectivity in all our endeavors: It made us great – and destroyed our old mother-ship Earth.
Except that the gluten (the sticky protein in wheat that makes dough so doughy) can cause myriad diseases: diabetes, arthritis, cancer, depression, autoimmune disease, skin diseases, neurological problems, vitamin B12 deficiency, and so on, and so on. (I am working on a comprehensive list of gluten-related diseases – will come soon).
And gluten is not only found in wheat – it also is in rye, barley and – as a slightly different but related protein – in oats.
You know the story from the Bible about the Golden Calf? Well, in Persepolis I got an idea why the Golden Calf was such a threat Abraham’s God: It was a fall-back into the era of many gods, polytheism. Worse: it went directly to where the money was: to the cow. The One God had to be angry if they could circumvent him. Look at the picture of one of those double-cow capitals of Persepolis – on the “medical questions?” page here).
But back to gluten: About one in a hundred (or a little less – depending on your ethnic background) cannot digest gluten well. If you are reddish or blond, blue-eyed and fair-skinned, you have higher likelihood to be intolerant to gluten – but I have certainly seen the disease in dark-haired people; even in Africans and Asians.
There is not cure for celiac disease – the only recourse is to leave out all gluten in your diet. Some people have a hard time to let go of bread, cookies, cake and pasta. But once you realize that you can eat rice, beans, lentils, garbanzos as much as you want, you suddenly are not only disease-free but you certainly live healthier because all our junk food is based on wheat (and fat).
You might have guessed it: If you are already depriving yourself of all fun in life, you can as well drop milk and dairy products – as they are the other big culprit at the root of many inflammatory processes in your body. Read More
