If the Government would ask me for my opinion of redesigning the food pyramid – which they won't because they go the food industry – this single principle would guide my food choices: Freshness.
There actually is no other food than fresh food; everything processed, enriched, manipulated, enhanced, improved, ready-made is not food but inferior food substitute. “Food ersatz” cannot build and repair cells as fresh food can – the outcome is stunted development and disease in the long run.
If you think you are doing yourself a favor by eating, for instance an apple-flavored nutritional bar – think again. That bar has too much sugar and salt, to start with, promoting obesity, diabetes and high blood pressure – cornerstones of the metabolic syndrome. Its ingredients are made to have a long shelf-life. Why would you want to eat something even mold doesn’t want to touch? Its oils a hardened to make them not go rancid quickly – and in turn those hardened fats will harden your arteries. Its apple flavor is artificial and does not what a daily apple does so well: Keeping the doctor away.
Good health is very easy: Move a bit every day, eat well and get enough rest. Then, love a bit – and you are all set.
The devil of course is in the fine print. What does “eat well” mean? Your mind starts spinning if you listen to all the advice in books, online and on TV. But all you have to know is: freshness. Go to a supermarket aisle and buy four different vegetables. Preferably organic (But organic is second on the list; freshness is first). Prepare a meal today with two of the veggies; another meal tomorrow with the other two.
Here is what we had for dinner yesterday: red beet salad (made from scratch, of course), Chinese baby bok choy, cod with cilantro and dill, split peas; frozen blueberries for desert. Today we will have red chard with garlic and olive oil, butternut squash puree, hake fillet with green sauce, red quinoa; pineapple mousse for desert. Tomorrow I will slow braise grass-fed ribs and white cabbage and parsnips with caraway, and serve it with cauliflower and chana dal; for desert the rest of the pineapple.
None of this takes long cooking (the green sauce I have frozen from last time). But we will have a great dinner every single evening. Ordering a pizza would not give my family the same health benefits. Read More

Have You Coddled Your Hippocampus Lately?
February 2, 2011
A recent study shows that brisk walks boost memory in older adults. And makes your hippocampus swell visibly on MRI. I bet this also applies to younger people.
The hippocampus is a worm-like structure deeply buried in your brain that is involved in memory formation. In Alzheimer, it is the part of your brain that will show the first signs of degeneration. A youthful hippocampus gives you mental plasticity, the opposite of which would be the obnoxious inflexibility that some older people show. About six to nine miles a week in this study was linked to better brain function. Walking even more did not seem to have more effect on the brain.
It comes down to walking ten minutes in one direction, turning around and walking back ten minutes, which can be done during lunch hour.
Another study showed that people who walk faster live longer. That bodes badly for me – I am a slow poke. But we can safely deduct that people who don’t walk will not make it long at all.
Walking also boost mood. If I would be a moody person (which I am not), I would do three things: go for a daily walk during daylight, end every hot shower with a cold one, and take herbal preparations – in women particularly, herbs against PMS or helping with post-menopause. Not to mention that I would turn to fresh, nourishing food and away from junk.
Walking per se is good for you. Two other studies have shown, that the effect is even better if you walk on uneven surface – like on pebbles, at a beach or in hilly terrain. Walking on pebbles decreases high blood pressure, and makes you less likely to get Parkinson’s. Using more muscles and consequently more brain can explain these results.
The most dramatic effect, I think, that daily walking can have – besides on memory, longevity, hypertension, Parkinson’s and mood – is that light boost vitamin D production under your skin – even if it is just the pale little area of your face reaping the rays. Vitamin D has become an important research focus as it wards off bone loss, cancer, multiple sclerosis and infections.
Walking will also lead to less weight and fight the dreaded metabolic syndrome (diabetes, high blood fats and hypertension) better sleep – all exercise does. And better sleep has been shown to increase overall performance, mood and resistance to infections.
In New England presently, walking the icy streets among huge snow banks is not that enticing. But I bet snow shoveling has all the above benefits, too – if you avoid hurting your back and don’t slip on the ice. At least I hope. Because I spend the morning digging out our walkway and garage driveway. At least this I know: The cold stimulus is a trigger for better immune function: Snow-shoveling in freezing temperatures improves my ability to better fend off flu and the common cold. Read More
