the easiest way to make bread

There's been an upsurge in baking recently because of TV shows. The Great British Bake Off and Paul Hollywood's Bread showed what can be done. Paul Hollywood's Bread has just ended, and in the penultimate episode he showed us how to make soda bread. He said that it's the easiest way to make bread.

I don't believe that. I have been making the Grant Loaf. This is a method of making bread that does not use kneading and does not require flour all over your kitchen surfaces. There are lots of recipes on the Internet, this one is from the BBC. It uses more water than traditional methods. You mix the flour, yeast, sugar, salt and warm water together (with a spoon, not your hands) then pour/spoon into your baking mould. Leave to rise in a warm place for a time then put it in the oven.

If you buy the flour from supermarkets that are intended for breadmakers then you don't even have to add yeast and sugar, they're in there already.

The new silicone baking moulds are fantastic. The bread does not stick at all. They look like plastic and are flexible. They come in different colours. You can get them from £1 shops. They come in all shapes and sizes, including bread baking tin shapes.

should you cut back on pasta for your kids?

On Saturday (23/03/13) there was an article in The Times called 'Five foods you must cut back on' by Rachel Carlyle and Melissa Little. This was in the Child Health section. Number one of these five foods is 'Refined carbs'. They are including pasta and white rice as among refined carbs. It is true that some starchy foods are not so good to eat. They are digested rapidly whereas it is better to have starches that are digested more slowly.

I agree with them about mashed potato and white bread. However, I do not agree with them about pasta and rice. It is not true that eating pasta or white rice (if it is long-grain) is 'a bit like tipping a packet of sugar straight into the bloodstream'. Pasta and rice are cheap foods that a lot of parents rely upon to feed their children and themselves. They are quick and easy to prepare and do not require any skill. Children love them. So if they are telling the parents of Britain to stop feeding their children pasta and rice that is a big deal.

The way that we can see how rapidly a carbohydrate is digested is by looking at the Glycemic Index. The higher the number on the Glycemic Index of a food the less valuable it is. Below I have given the GI values for a number of starchy food, with the lowest GI at the top.
  • pasta (depending on how cooked and shape) 40 to 60
  • brown rice 55
  • white long-grain rice 56
  • basmati rice 58
  • sugar (sucrose) 68
  • white short-grain rice 72
These figures are averages. It can be seen that white short-grain rice is indeed as bad as sugar. However, other forms of rice, and especially pasta are nowhere near as bad as sugar. I think that they are assuming that only wholegrains are good for you in terms of how rapidly a starch is digested. There is some truth in that, wholegrains tend to be digested more slowly, but that is not the only factor.

So, I would say to the parents of children don't stop serving pasta and rice to your children. Instead cook your pasta for a shorter time and choose a shape that is thicker. Choose brown/long-grain/basmati rice instead of white short-grain. A variety of different types of rice is more enjoyable anyway.

Pasta and rice are cheap and easy to prepare. It doesn't take much to make them palatable. You can use pasta sauce from a jar, but I have found out recently just how cheap and easy it is to make a pasta sauce from a tin of chopped tomato and a few other ingredients. I have made an arrabiata pasta sauce - the recipe is widely available on the web.

The big problem that I have with this article is that people are always saying that healthy foods are expensive. They recommend wholegrain pasta and brown rice. These are more expensive, although not always as expensive as you might think. Ordinary pasta and (long-grain) white rice are fine though, and they are cheap and children love them.

Another thing that they recommend is small amount of carbohydrate (of any kind). I disagree with this. I think that the bulk of our calories should come from low-GI starches. If not from them, where are most of our calories going to come from? They mention fats. They say saturated fats are bad but unsaturated fats are good. Not all unsaturated fats are good though. Omega-6 rich fats are not a good thing even though they are unsaturated.

They seem to be a bit confused about guidelines. They state 'The guidelines say that fat should make up approximately 35% of your calorific intake' and 'Children do need a bit of saturated fat, but only 10 per cent of the total fat intake should be saturated'. In fact, the guidelines say that total fat limits for children/adolescents from the age of 4 to 18 should be 25% to 35% of total calories. So they should be having less than 35%. The guidelines say consume less than 10% of calories from saturated fats. So these figures of 35% and 10% are upper limits and not how much we should be eating. We should be having less than these amounts, considerably less. Children don't need any saturated fat, but 10% should be the upper limit.

can vegetarianism be unhealthy?

There was a very interesting article in the Independent newspaper on Thursday (21/02/13) titled From vegetarian to confirmed carnivore where John Nicholson stated that when he was eating a low-fat wholefood vegan diet he felt ill. He became obese and had irritable bowel syndrome (IBS), diarrhea, fatigue and headaches. His partner, who shared his way of eating, had depression and mood swings.

They decided to ditch the wheat, rice and potatoes and eat lots of meat, butter, cream, lard and goose fat. He felt better straight away and lost lots of weight. His cholesterol levels went down. This seems on the face of it to contradict everything that I have been saying on this blog, about people eating less meat and more starchy foods and vegetables. However, I think I can understand what is happening here.

John seems to have gone from one extreme to another. From veganism to eating lots of meat and animal fat. When people make radical changes in the way that they eat, often excluding whole food groups, they often gain weight or lose weight without trying. They may be getting more calories or fewer without knowing.

The placebo effect might explain some of why John started to feel a lot better straight away. I don't want to dismiss what he says though. It is possible that John had an iron or zinc deficiency which was rectified as soon as he started eating meat, especially as his first meat was ox liver. It might even be that he wasn't getting enough protein, although it's not that difficult to get enought protein on a vegan diet. Another possibility is that he was suffering from an allergy to wheat.

If he had been eating soya products, that might have caused problems. Soya contains phytic acid which reduces our ability to absorb iron and zinc and trypsin inhibitors which reduce our ability to digest protein. This might not be a problem with traditional foods like miso, tofu or tempeh, but might be more of a problem with other ways of eating soya.

John seems to have moved to what is in effect the Atkins diet. In the Atkins diet people do not try to control calories but eat as much meat and animal fat as they like. The main thing they are trying to avoid is carbohydrate. It is a low-carbohydrate diet. When you digest carbohydrate, glucose enters the bloodstream. If you have too much glucose in your bloodstream your body needs to remove the excess or it will cause problems. Your pancreas secretes the hormone insulin which tells the body to remove some glucose.

In most people insulin and glucose levels rise and fall. Too much of this causes problems though. Obesity is only one problem that can happen when we have big rises and falls of insulin and glucose. Obesity can give rise to other problems. It is now recognised that this is one of the biggest causes of ill health.

People on the Atkins diet tend not to eat vast numbers of calories because the diet is less varied than a normal diet. They can easily get bored with it or even a bit nauseous contemplating the prospect of yet more meat and fat. It is often said that people crave fat, but a lot of the fat we eat is hidden. If you eat a slice of cake, you don't realise how much fat is in it because the flavour is masked by sugar or something acidic such as lemon. We eat so much fat not because we love it so much but because we don't know it is there.

I don't have a problem with the Atkins diet. It does seem to work at helping people to slim. I do wonder about the long-term effects of staying on the Atkins diet though. I'm not just worried about heart disease and strokes, reducing protein has been linked to increased longevity.

I wonder if it would work just as well if instead of meat they ate fish, and instead of eating butter and lard they ate avocados and olive oil. In Crete people traditionally got lots of their calories from olive oil and far from harming them it seems to have contributed to health and long life.

Also, there are some forms of carbohydrate that are better than others at not flooding your bloodstream with glucose. Starch is better than sugar, and the amylopectin form of starch is better than the amylose form. You can measure the effect that a food has on your blood glucose levels. A low glycemic index (GI) is better than a high glycemic index. Long-grain rice is better than short-grain rice. Brown rice is better than white rice. Pasta and porridge are good too. If you eat some low GI forms of starch it won't have too bad an effect on your blood glucose levels.

Vegetables can seem to have a high GI but really they are mostly OK. Baked potatoes are not good though. So I shall continue to eat my long-grain rice and pasta, together with my pulses and vegetables. I do eat meat, cheese, fish and eggs sometimes but not every day. What John Nicholson has said in no way invalidates what I have stated on this blog about the problems of trying to feed everyone on the planet with lots of meat. We can't feed 7, 8 or 9 billion people with a diet high in meat.

A good point that John makes is that not everbody is the same. People vary as to what sort of foods they thrive on. I think it is likely that some people digest starch more readily than others. If so, they are less likely to thrive on a high starch diet even if it is low GI.

In case people are thinking that they can just add butter and cream to their normal foods and get away with it, it doesn't work like that. If you want to eat lots of meat and fat and lose weight then you would have to go on an extremely low-carbohydrate diet, or you will just put on weight.

reducing meat consumption

In this week's New Scientist magazine (23/02/13 page 5) it tells us that the UN Environment Programme has revealed that 80% of the fertiliser use in farming globally is for meat production. Pastures are fertilised to boost grass production and for fodder crops. I guess that by 'fodder crops' they mean maize and soya, and also wheat and barley (I'm not sure if soya requires nitrogen fertiliser, as a legume perhaps it does not).

Half of the fertiliser put onto the land isn't used by the crops. It runs off the land into the rivers and seas and causes environmental damage. The solution, according to the authors is for fertiliser to be used better and for us all to eat less meat.

This figure of 80% is a surprise, and it fits in with what we already know about how much of the crops grown - mainly maize and soya - are fed to farm animals. It's also mentioned in the Guardian article about this UN report (18/02/13).

In the Guardian article it says that the authors of the report are not suggesting that we give up eating meat. They are suggesting we become demitarians - eating half as much meat as we are used to. I agree with this, but there are a couple of points I'm not so sure about.

The lead author, Professor Mark Sutton, says we should replace most of the meat on our plates with vegetables. Meat provides us with protein and calories, and although we could do with less of both of these, we're probably going to need something to make up for the shortfall if we replace meat with carrots, broccoli etc. Vegetables don't have much in the way of protein or calories, but pulses are a cheap form of protein (and have some calories) and grain in the form of rice and pasta are the cheapest form of calories (and have some protein).

One of the problems in asking people to eat less meat (or less junk food) is that they think they're going to be expected to live off celery and lettuce. They don't have to, they can have tasty rice and pasta dishes. Vegetables are thought of as too expensive for poorer people, which isn't true, but it's easy to see how rice and pasta are the cheapest foods, much cheaper than any form of meat.
Professor Sutton also says that people in poor countries should be 'allowed' to increase their consumption of animal protein. It is true that in some countries people don't get enough protein, although in other poorer countries people do get enough - it's just that they like the idea of eating more meat. I don't see why it has to be animal protein though. Since the UN changed it's official estimate of how much protein people need downwards in 1985 we've known that people don't need that much of it.

People who aren't getting enough protein are usually people who aren't getting enough food. If someone gets enought calories from rice they will be getting almost enough protein. It doesn't take much in the way of beans, peas or lentils to give someone both the quantity and quality of protein that they need. In Indonesia people were encouraged to eat less tempeh (a traditional food deriving from soya beans) and more chicken. I think that was wrong. Protein from tempeh or tofu, or beans or lentils, is just as good as animal protein. It's more efficient to convert soya beans into tempeh or tofu than into chicken and pork.

Professor Sutton says that chicken and pork are the meats that cause the least amount of environmental damage. "Chicken is one of the most efficient [meats] as it grows very quickly and you can collect the manure," he says. Chickens have one of the best conversion rates of grain and soya to meat. Better than pigs, so let's not encourage more pig keeping. I would expect eggs to be an even better way of getting cheap protein than chicken meat. Also, freshwater fish and things like crayfish are even better than chickens. Mammals and birds use up a lot of their calories in generating heat internally, so cold-blooded animals are even better converters of plant protein into animal protein.

So I agree with the principle of demitarianism, but there should be more emphasis on grains (like rice and pasta) and pulses. We shouldn't fall into the trap of thinking that food falls into a spectrum with affordable junk food at one end of the spectrum and unaffordable fruit and vegetables at the other end of the spectrum. Also, I don't think we should encourage the poorer countries of the world to produce more animal protein.

food mislabeling

Food mislabeling is an issue that's been in the news a lot recently. This post isn't about horse meat though. It's about something less important but it does say a lot about the attitude of retailers. Yesterday I went to Borough Market in London. I wanted to see what it looks like now all the building work has been completed. I also wanted to buy a few things, like blood oranges.

Blood oranges come from southern Italy and Spain and are available at some markets now. They have a different colour and taste from the usual oranges. There are different cultivars, the Moro being the best flavoured. There are several places in Borough Market where blood oranges are sold. The first one I came to didn't label the blood oranges on display with the name of the cultivar. I picked up two and asked the assistant at the till if she knew what the variety is. She didn't know.

The next place I went to I could see that the name on the box was Moro. This was the tiny lettering that the grower puts on the box that the fruit are transported in. Again, there was nothing that the seller put on his label to say what cultivar it is.

The third place I went to was the biggest of the fruit and vegetable sellers. It is called Turnips. There were a number of boxes of blood oranges, and they had placed on top of them a laminated information sheet. This sheet was all about the Moro cultivar. So I assumed they were all Moro. Until I looked on the box and it said Tarocco. So what are they, Moro or Tarocco? I think what they do is to put the same information sheet on their blood oranges, irrespective of what cultivar they are.

Bear in mind that what they say about Borough Market and similar places is that if you're not sure then you can ask the vendor and they will tell you all about the produce that they are selling. All the people working there were busy, but if I had asked I would probably have got the same response as at the first place.

It's not important if someone like me can't get my Moro blood oranges. In fact, I can get them, elsewhere. What is important is that even at somewhere like Borough Market they can't even be bothered to get their labeling right. I can't work out if they are stupid or if they think we are stupid. Another thing I don't like is when I ask for something, they tell me it's out of season, even when I know it is available elsewhere.

I've been getting my Moro blood oranges at 4 for £1 from Berwick Street market in Soho. So they're not some kind of expensive item that ordinary people can't afford.

I've got 3 more examples of casual labeling, all from Sainsbury's. A couple of years ago I bought a cheap camellia plant. It was labeled as the variety Debbie, a variety that I am familiar with and I like the form of it's flowers. It's in flower now, for the first time, but it's definitely not Debbie. It was quite cheap to buy, and if they had said that it could be any variety, or if they said it was had pink flowers, I might still have bought it. But I don't like being told that it is one thing and then finding it is something else.

I was in the bakery section of Sainsbury's recently and there were 4 round loaves in a basket. They all looked exactly the same, they all had the same packaging, but 2 were labeled 'sourdough' and 2 were labeled with a fancy French name that I didn't recognise. I think that they were just all the same.

In some of the bigger Sainsbury's they have a café. I like their filter coffee. But if I ask for filter coffee, one of 3 things happens. They either pour some coffee out of a vacuum flask. This seems to taste the best. Or they have a machine with a tap. Or they use a similar method as when they're making latte or cappuccino. I think this is technically called an Americano. I don't mind so much but I would like to know what I'm getting.

horse meat, burgers, asthma, eczema and salt

Listening to the radio yesterday evening proved to be very infomative about the food that we eat. I turned on to Radio 4 at 9 pm and heard the news. It said that horse meat has been found in burgers, including Tesco burgers. This is up to a third of the meat in burgers being horse meat.

I think I heard someone mention 'cross contamination'. This is not cross contamination, this is systematic fraud. Horse meat is intended for pet food and is unfit for human consumption. Horse meat in itself is not a bad meat to eat, but you need to understand that meat that is intended for human consumption is handled according to certain standards, including hygiene standards, and meat that is intended for pet food is handled with much lower standards. Horse meat is not intended for human food, and will have been handled to much lower standards. And don't think it is just horse muscle tissue that is in burgers. It's going to be lots of stuff, including the genitals. Officials have said that human health is not in danger, but how do they know that?

It's not surprising so many people have become vegetarians. They must be glad they did.

The irony is that most people would not eat a cow's heart. And yet they eat cow's heart every day in their burgers. If I was in a restaurant in France and cow's heart was on the menu, I might have some. If horse meat was on the menu, I might have some. If I thought it was quality meat and not something that died riddled with disease and has spent a week in a skip outside an abbatoir because it was originally intended for pet food.

I don't eat cow's heart or horse meat because I don't eat burgers. Yet I wouldn't turn up my nose at cow's heart or horse meat. Most people would turn their nose up at them, yet they eat them every day in burgers.

After the news was the Inside Health programme. They talked about a few things, but most interesting to me was the research linking junk food to asthma and eczema, and experts talking about salt and all the uses that salt is put to in junk food. I was aware that excessive salt intake leads to heart attacks and strokes, and I was aware that most of the salt that people get is from junk food. I wasn't aware that salt is used to bind to polyphosphates in meat and fish products to create a jell that binds them. Without lots of salt they would just fall apart.

Bon Appétit!

 I found this on a forum:-

Horse is a perfectly edible meat, but plays no part in the legitimate meat processing routes in the UK or Ireland - so where was this horse meat from and how can anyone be sure that it was slaughtered and stored in accordance with current regulations?

he or she makes a number of important points below:-
  • where were the horses from?
  • were the horses healthy or did they die of old age or disease?
  • were they slaughtered in accordance with regulations?
  • was the resultant meat stored at the correct temperatures in accordance with regulations?
  • was it cheap knock-off past its use-by date horse meat from a country where horse meat is eaten?
If anything was not done properly with the last four points it could mean that there are public health concerns due to the risks associated with contaminated meat.

global food waste and factory farming

I read a letter in today's Daily Mail that expresses the most important points that I have been trying to make in this blog. Food waste is an issue prominent in the news recently, and Philip Lymbery of Compassion in World Farming wrote that feeding so much grain and soya to farm animals is another way that we waste food. I would have liked to place a link to this letter (Feed the world) in this post but couldn't find one, so I shall link to a post in his blog that has the same message.

I shall give a few of the facts stated in the letter
  • a third of the world's cereal harvest is fed to farm animals
  • 90% of the world's soya beans are destined for factory-farmed animals
  • for every 6kg of plant protein such as cereals fed to livestock, we get back, on average, only 1kg of meat or other livestock products
  • for every 100 food calories of edible crops fed to livestock, we get back just 30 calories in meat and milk
  • factory farms are food factories in reverse, they waste food rather than make it
There were two letters in New Scientist recently that interested me. The first was a response to a review of a book 'One Billion Hungry: Can we feed the world?' by Gordon Conway. The review said that we need to double global food production by 2050 (Separating the wheat from the chaff by Fred Pearce New Scientist 13/10/12).

Alistair McCaskill wrote a letter (10/11/2012) saying that if today's population stands at 7 billion and is forecast to rise to 9 billion by 2050, why would it take a doubling of food production to feed this extra 2 billion? Fred Pearce answered, and said we have to allow for rising demand - especially for meat.

Clive Semmens replied to this (01/12/12) by saying that it would be much better to try to reduce consumption - especially of meat - in the more affluent. That would be good for the global environment and for health too. He went on to say that he's not advocating vegetarianism, merely moderation.

This is exactly my point of view. It seems to me that trying to double global food production is just not going to work. It doesn't matter how much genetic modification you have, it's simply not going to happen. Making meat more expensive by taxing it and refusing to allow the opening of more factory farms will help enormously. We tax ice cream and put VAT on it because it is a luxury. We should recognize that meat is just as much a luxury.

That is not going to harm poor people. Firstly, the really poor are the 1 in 8 of the global population who go hungry. Secondly, if meat is twice as expensive but people eat half the amount it isn't going to cost them, and it won't affect them aversely in nutritional terms - just the opposite. The same is true of cheese and butter. Meat, cheese and butter are not and can never be cheap calories or cheap protein.

Maize, soya, wheat and anchovies are the cheap calories and protein. That's why they're fed to animals, after all. The almost billion people who go hungry would be quite happy to have extra calories and extra protein from whatever source. They have the knowledge of how to make these things taste wonderful, whether it's traditional Mexican cuisine or the traditional East Asian cusines. The more affluent of the world might desire burgers and other processed foods, but they should be encouraged to move away from the flavours of fat, sugar and salt. I know what I would rather eat, especially now that we know what goes into beefburgers, and I'm not just talking about horse meat.
