Food Combination Of Fruits For Better Digestion
The greatest benefits from foods and the most efficient digestion
come from simple meals with minimal food combinations. Thus, the first
principle of Food Combining is simplicity and compatibility in meal planning.
Fruits digest best when eaten by themselves as an entire
meal. In general, fruits should not be eaten with other foods. If they are,
they will be detained in the stomach causing them to begin formation.
Alcohol, coffee, tea, vinegar, condiments retard digestion
considerably.
Acid Fruits & nuts - Cheeses are ok because the high fat
content of nuts & cheeses acts like a separate meal from the Acid frutis by
digesting more slowly.
Acid fruits delay the digestion of sweet fruits.
Tomatoes - May be combined with Low Starch vegetables and either
avocados or nuts, and not with starches or proteins.
Sugar & Protein - Fruit & other sugars inhibit
gastric juice delaying protein digestion
Melons - Because they decompose even faster than the other
fruits. It is advised to eat melons separately from other fuits.
Avocados combine BEST with non starchy vegetables. FAIR with
acid fruits & starches. Avocados do not combine well with sweet fruits or
proteins.

Water - Every Drop Counts
After air, the next most vital thing for our survival is water. While at the moment we have enough water for our needs, a time is likely to come when our water supply runs out and we have to buy water at a price similar to fuel. The solution, which some people have implemented, is to save and store rainwater

More Efficient Renewable Resource.
New biofuel process generates energy 20 times higher than existing methods, and uses agricultural waste:
A new biofuel production process created by Michigan State University researchers produces energy more than 20 times higher than existing methods. The results, published in the current issue of Environmental Science and Technology, showcase a novel way to use microbes to produce bio fuel and hydrogen, all while consuming agricultural wastes.
Gemma Reguera, MSU microbiologist, has developed bioelectrochemical systems known as microbial electrolysis cells, or MECs, using bacteria to breakdown and ferment agricultural waste into ethanol. Reguera's platform is unique because it employs a second bacterium, which, when added to the mix, removes all the waste fermentation byproducts or non-ethanol materials while generating electricity.
Similar microbial fuel cells have been investigated before. However, maximum energy recoveries from corn stover, a common feedstock for biofuels, hover around 3.5 percent. Reguera's platform, despite the energy invested in chemical pretreatment of the corn stover, averaged 35 to 40 percent energy recovery just from the fermentation process, said Reguera, who co-authored the paper with Allison Spears.
"This is because the fermentative bacterium was carefully selected to degrade and ferment agricultural wastes into ethanol efficiently and to produce byproducts that could be metabolized by the electricity-producing bacterium," Reguera said. "By removing the waste products of fermentation, the growth and metabolism of the fermentative bacterium also was stimulated. Basically, each step we take is custom-designed to be optimal."
The second bacterium, Geobacter sulfurreducens, generates electricity. The electricity, however, isn't harvested as an output. It is used to generate hydrogen in the MEC to increase the energy recovery process even more, Reguera said.
"When the MEC generates hydrogen, it actually doubles the energy recoveries," she said. "We increased energy recovery to 73 percent. So the potential is definitely there to make this platform attractive for processing agricultural wastes."
Reguera's fuel cells use corn stover treated by the ammonia fiber expansion process, an advanced pretreatment technology pioneered at MSU. AFEX is an already proven method that was developed by Bruce Dale, MSU professor of chemical engineering and materials science. Dale is currently working to make AFEX viable on a commercial scale.
In a similar vein, Reguera is continuing to optimise her MECs so they, too, can be scaled up on a commercial basis. Her goal is to develop decentralised systems that can help process agricultural wastes. Decentralised systems could be customised at small to medium scales (such as compost bins and small silages, for example) to provide an attractive method to recycle the wastes while generating fuel for farms.
Worldwide, the market for biofuel production is expected to reach $100 billion by 2018, compared to $35 billion just a decade earlier.

The Story Of Agriculture And The Green Economy
The future of our world depends on addressing global challenges now. We need to create sustainable livelihoods, feed a growing population and safeguard the environment. We need to make the global economy green.

Why Organic Food?
For decades our food and water have been contaminated by powerful, harmful pesticides which have been promoted as necessary for better agricultural output. But the reality is that we don't need pesticides for better yield, and their use is not only deadly for health but results in expensive farming methods.
The solution is to adopt organic farming, which is possible and profitable, as the state of Sikkim has shown.
