New potatoes

New potatoes straight from the garden can be eaten by many diabetics. Having said that, we are all different; some can enjoy brown rice, but others cannot.

Russets are to be avoided by all, along with all refined starches, as they cause an immediate spike in blood glucose.

The trick is to do a test about sixty minutes after a meal of new potatoes; if it has not returned close to the levels before dinner then you should avoid them too.

Your spuds are controversial if you are resistant to insulin; the problem is that there is a vast difference in the glycemic index and load between varieties.

Boiled russets and particularly french fries are simply a disaster for diabetics, and actually not good for any of us.

Those who have no desire to be injecting themselves with insulin in the future should avoid them.

That extra sugar that is being let loose in the blood attaches to the red blood cells, forming what is known as an advanced glycation end product; it is very damaging to capillaries and the great vessels. Nerves and the retina of the eye are affected too.

The joy of new potatoes is that they can be enjoyed in moderation by many diabetics; and, for all those who love a spud, straight from the garden they are so tasty. When you cut into them, they give off a satisfying crunching sound and feel quite different to those from cold storage.

What exactly can be called a new potato?

Marketers cheat and in the UK some spuds that have been in storage for over six month are being sold as new potatoes, so it is a case of buyer beware.

A new potato has a thin skin that can be easily scraped off with your nail; it does not keep so it should be eaten within three days before it turns to starch.

So you will only get them in small packets and thus they cost more; unless you grow them yourself. Lift only enough for today and perhaps tomorrow. Bring the children into the garden with you; they simply adore hunting for the spuds as you turn the sod.

Try to avoid having two starches at the same meal; rice and corn on the cob could be your undoing.

Lifting new potatoes.

New potatoes along with the reds are known as waxy, as they have half the glycemic load.

There is another good reason to enjoy new potatoes; they are not sprayed with a herbicide like Glyphosate, marketed as Roundup, just days before harvesting to desiccate the plant. Scientists have changed the grading from possibly to probably causing tumours; residues are in many of the foods we eat.

Monsanto, the company that manufactures glyphosate is not happy. The European Court of Justice has in March, 2019, forced them to release the studies that supposedly claim that Roundup is safe, and has no effect on our well-being; up to now they have fervidly refused to allow anyone to peruse their research methods. Now independent scientists have the opportunity to see if it is bogus science based on falsification of the statistics; in short, fake news.

Do you ever wonder why almost every family is touched by the big C or an autoimmune disease? I scrupulously avoid all the chemicals in food; I treat the whole lot with suspicion. That puts me on the edge of orthorhexia but having witnessed personally so much metastatic sickness amongst patients and family, I have no desire to go out that way.

I would rather be labelled obsessive, a food snob and a nut.

Remember, new potatoes have much less starch than those that has been stored for months; about a half. Many diabetics report they cause no glucose spike at all; test yourself.

Even better, if you allow them to cool overnight in the fridge and then reheat them, retrogradation links the molecules of the amylose together so that they pass through the small intestine largely undigested.

Instead of being absorbed, the starch passes into the colon to the microbiota that inhabit the intestine; that means less chance of getting an autoimmune sickness like Parkinson's disease too.

If you have a problem with moles in your garden, as we do, then do not plant your seed potatoes in trenches; we have learned the hard way to set them out randomly. Otherwise, having discovered the first, the little devils will devour the lot.

Actually moles do a lot of good in the garden, aerating the soil, but they can damage your new potatoes too; planting their favourites in the mesh bags that many foods like onions come in certainly does help to keep them at bay.

How to plant potatoes will help you get started; you will notice that we used to plant them in trenches, but no longer.


Paraquat is the most highly toxic herbicide used today[1], particularly in developing countries like South Africa. It is banned in the EU and many other countries but continues to be used as a preharvest desiccant on potatoes and many other crops.

It is just another reason to enjoy new potatoes from your own garden; you can be sure that your spuds are free of very poisonous chemicals.

Since there is absolutely no testing of herbicide residues in food grown in SA, we can assume there paraquat is there in your commercial potatoes.

It is just one more reason why you should develop your green home. Are we just becoming totally neurotic about our food? You be the judge.

Remember that refrigerating any carbohydrate overnight causes the starch to retrograde; molecules link together making it more difficult for the enzymes in the small intestine to digest them. The net result is less of a blood glucose surge and only a minor need for insulin from the pancreas; and so it is also less fattening as it is not immediately stored as glycogen and any excess as adipose.

Instead the good bacteria in the colon feed on them greedily to produce many necessary byproducts, but little glucose, and more gas unfortunately. Read more about this at reheating resistant starch.

Let us state it candidly, if you want to live long in the land avoid all processed carbohydrate, and in general keep your total starch to less than 150g per day.

Diabetics should be less than 50g per day, and even lower if they are unstable.

It is almost impossible to lose weight if you are obese, unless you cut your carbs below 50 grams per day.

Research from Tufts University shows the average American is consuming half a US cup of sugar per day, much of it hidden in sauces, soups and cereals; that alone is 100g.
