New Rice Crop to Save the World

The world needs another green revolution. New high-yielding crops in the 1950s and 1960s changed everything. They took Mankin out of the diminishing-food crisis. The new cereals and rice impacting greatly on developing countries. Output increased. The food crisis was averted.

People Know a Health Diet

Health: We know the correct foods to eat but we ignore it.
Understanding good nutrition is very easy. Eat plenty of vegetables in as wide a range as possible. Have meat about every other day. Only eat processed food if you have to for social reasons. That couldn't be simpler could it? However, people are still looking for fad ways to change their body to idealized proportions.
Vegetables for good health
We also know the best way to live our lives but we ignore it. People like the taste of takeaway food and consume it in extreme amounts. Frozen processed meals contain huge amount of added sugar, salt a already processed ingredients. Young people do not buy and prepare fresh vegetables for cooking anymore. Most of us also do not do enough exercise. Many imbibe alcohol while watching a downloaded movie just about every night.

There isn't much doubt that eating copious amounts of tasty food is a pleasant pastime. Food certainly isn't consumed to stay alive. It is an end in itself. There is a price to pay with the burden on the health system increasing every day. Treatment for non-infectious diseases is rapidly rising. Cardiovascular disease, cancer and musculoskeletal problems are becoming "normal". People just accept them as part of life.

Oh, and stay away from bread, potatoes and white rice. They may be good to sustain the poor, but eaten daily they will kill you! Bread and rice have only been around for 10,000 years. This is a very short time. Humans did not evolve to deal with them.

Sweet Versus White Potatoes

You don't know which is better for you - standard or sweet potatoes? Well read on. While many people rant on about the benefits of sweet potatoes, ordinary potatoes are good for you too. There is a drive to reduce the consumption of starch. But be careful about this. Human beings have been eating tubers for hundreds of thousands of years. It is starch from wheat that is new to us - only ten thousand years. Our bodies have evolved to be able to digest tubers.
Processed food like flour is unnatural. Tubers have starch balanced with other elements. This slows down digestion and releases sugar very slowly into the body. Bread is digested quickly. You are hungry again in no time.

Sweet potatoes are not the best low GI (slow sugar release) in an absolute comparison of standard potatoes. Some varieties of potatoes are floury while others are waxy. They differ in GI qualities.

Cooking methods change the GI index. Boiling is best because water binds with the starch. Baking concentrates the sugar. Cutting up before cooking preserves the starch. Cooking potatoes whole raises sugariness. These methods can make sweet potatoes have a higher GI than standard boiled potatoes.

The thing about antioxidants can be ignored. In tests with mice it was found the long-living mice had more oxidants in their bodies than shorter-living ones. All vegetables are high in minerals, vitamins and trace elements. Sweet potatoes compare to Brussels sprouts and spinach, but white potatoes are sufficiently high. Note that we eat potatoes with other things. The "other things" provide missing elements that potatoes lack.

Robot to Replace Dumb Farm Workers

The robot age is here!  That is if you believe what scientists are trying to tell us.  Shouting and waving your hands in the air about a new thing is par for the course.  We have heard it all before: mew thing, great leap forward, and so on.

Apparently, the new gadget is a robot for use on a farm.  Developed in Australia, the machine wanders around the farm "keeping an eye" on crops and pests.  It is guided by hyperspectral cameras and sensors.  The initial field test, forgive the pun, was at a vegetable growing property where beetroot, spinach and onions are grown.

The robot has a mechanical arm for pulling up weeds - wow productivity will go through the roof!  Just how fast will this thing go?  Unfortunately, it moves very slowly.  Scientists say it will free up staff from manual labor.  This is absolute rubbish.  How does it know what is a weed and what is a valuable plant?

Unless it does high-tech stuff it will not prove to be beneficial.  If it can detect pests and diseases very early, it will be useful.  However, manual labor does take a high level of intelligence.  You must know how the job is to be done usually without supervision.  Scientists wrongly believe that farm workers are dumb.

New Technology Adopted by Citrus Grower

About the only way for a business to succeed in this day and age is to improve productivity by developing new technology not by breaking employees' backs. Increasing productivity by making people work harder has never worked. It is only successful in the short term.

The Costa Group which exports high quality citrus fruit to Japan has installed an infrared Brix sensor system to improve the selection of the best for export. There will be no rejection by customers because the Brix scale shows how sweet an orange is for example. There is also higher sales of blemished fruit that are very sweet according to the scale.

It seems odd that the Brix system is not shown to domestic customers. There is a down side: minerals and trace elements are not measured. However, there is no doubt that Australian consumers would like the Brix scale placed on the sales price ticket of fruit.

Like keeping out New Zealand apples, Australian growers will go to extremes to sell low quality produce. The strangle hold on the industry must be broken. Australians should have the right to buy the best, no matter where in the world it comes from. Market manipulation is supposed to be illegal.

Being Overweight Causes Osteoporosis

Being overweight leads to heart disease but it can also cause osteoporosis. This is due to people cutting out vital elements in the diet in their attempts to lose weight. Dairy products are essential for strong bones. Yet milk, butter and cheese are precisely what it being disregarded in diet by 30 per cent of women. Another danger is the consumption of bread. An astounding 40 per cent of women have stopped eating this food that is calcium fortified.  It must be remembered though that bread has only been part of the human diet for 10,000 years.  It could be the cause of many humans "diseases".

Research has shown that the real cause of weight gain is carbohydrates. Yes, it's as simple as that. People who only cut out sugar lose weight very quickly and maintain a low body weight thereafter. People concentrate on eating low fat diets even though research shows this to be the wrong thing to do. Look at movies made up to WWII. Actors and actresses and especially the extras were all quite skinny then. In those days most Western nations had not developed the high sugar habit. And most workers then went to work on a large fatty fried breakfast.

Danger in the future will not be with low fat diets. Young people today just refuse to eat vegetables. Cabbage and broccoli are high in iron. Young people steer well clear of these. Hope lies with the intake of fish. The young do like fish. Note the dash for seafood at Christmas. Fish contains calcium and minerals. Processed food is high in sugar. Government needs to have a policy aimed at lowering sugar intake in our diets.
