How does one have healthy life style?

It is supposed to be scientifically determined healthy diet. It appears that MyPlate might have been based not just on science but also on the demands of the food industry lobby.
The charge comes from a respected source, Harvard School of Public Health.Is USDA Pandering to the Food Industry?
In the past, he had also criticized the previous USDA food pyramid for the same reason.

Perhaps you have turned a bottle of fat burning supplement over and checked out the components inside it? Deciphering just precisely what is within the product could be a daunting challenge. You might have probably never heard about four from five from the ingredients in almost any given fat burning supplement Fatburners for women. Actually the most typical ingredient present in fat burners, caffeine, may be the just one you recognize. Ma huang, chinese people term for ephedra, had been a common ingredient in lots of fat burners before its ban in 2004. Huge numbers of people took ma huang containing products and simply assumed it had been safe.

Willett is a respected epidemiologist who literally wrote the textbook on nutrition. Now he has put together what he thinks is a healthy plate.

Some of Dr. Willett’s observations on MyPlate include:
MyPlate recommends dairy at every meal despite a lack of any scientific benefit of milk and despite the fact that too much dairy may be bad for you.
USDA does not distinguish between healthier proteins such as seafood, nuts and beans and less desirable proteins such as red meat and cold cuts.
USDA makes no distinctions between healthy vegetables and potatoes (or even french fries) or between whole grain and refined flour or between beneficial fats and trans-fats.
USDA is silent on unhealthy sugary drinks.Harvard Recommendations

Walter Willett’s Healthy Plate is a start. He says, “Pump up the produce (not the potatoes). Pick healthy protein sources and whole grains. Drink water instead of sugary drinks. Use healthy plant oils. And stay active.”
He also has a handy-dandy food pyramid for ready reference. Click on the image for a larger version.
