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.

High Meat Consumption Blamed for Obesity - Questionable!

In the twentieth century Australia was dominant in swimming at international events. This was largely due to the high consumption of meat in the diet of Australians. As time went by other nations noticed this and their athletes ate more meat. Today, Even small island nations have access to reasonably priced beef, pork, lamb and poultry. Consequently, Australia's dominance has waned.

Despite consuming a lot of meat, Australians did not die at a young age. Indeed, longevity was extended. New research points to an increase in heart disease, obesity, cancer and diabetes that do tend to shorten life. An example was given of Hawaii where these diseases are rapidly increasing. Red meat is seen as the major cause.

This research has flaws. Higher red meat consumption cannot be directly linked to more "modern" maladies. It could be coincidence. No tests were done on the rising consumption of refined carbohydrates. The call for more vegetables in the diet will improve the situation, but only if less red meat and refined carbohydrates are consumed.

There is an indirect link between red meat consumption and more disease. The feeding of antibiotics to animals to improve body weight has impacted on humans. Antibiotics are not so effective in people generally. Some countries have banned this practice, but all nations need to do so. Overall, there is no evidence of antibiotics in animal feed leading to modern diseases. Control of infections is the biggest problem.

Danger From HIgh Salt Intake Is Overstated

Salt will kill you. That it is the idea we are all expected to accept, but there is no real proof that this is the case. No research has indicated that a high salt diet increases blood pressure. Indeed, a century ago Africans would travel a thousand miles to get it. Salt is essential for life.

Consumption 50 percent higher than the recommended level is nothing to worry about, considering it is only a "guesstimate" anyway. High blood pressure has increased in the community despite salt intake remaining about the same per person for 40 years.

Like a tax on fast food will not stop people from buying take away, so campaigns to reduce salt intake will not make people consume less. If manufacturers of processed food take salt out of their products consumers will not buy their products. Salt definitely improves flavor.
