The initial Food Pyramid divided the three groups: carbohydrates, vegetables and proteins into
six new groups as follows:
1) Carbohydrates: Bread, Cereal, Rice & Pasta
3) Fruits - any fruit or 100% fruit juice counts as part of the fruit group. Fruits may be fresh, canned,
frozen, or dried, and may be whole, cut-up, or pureed.
Proteins into subgroups:
4) Meat, Poultry, Fish, Dry Beans, Eggs, and Nuts
5) Milk, Yogurt and Cheese
6) Fats, Oils, and Sweets
The Food Pyramid has so to say 'evolved' over the years. Still, it remains a way which gives people a better understanding of how to eat healthy. Generally used to educate young children about healthy eating, food pyramids are usually bright in colour and illustrative, as the picture above. But these pyramids are not exclusively for kids.
These pyramids are sometimes challenged by researchers, who claim to come up with better pyramids, better explaining a healthy lifestyle, etc. Once such researcher is Walter Willet. He is an engineer of several influential studies on health and nutrition and has spent decades looking at how our diets affect our health. Now he has come up with his own "Healthy Eating Pyramid".
Walter Willet's new food guide pyramid has features in common with its counterpart, i.e. the two share the same shape - the foods we should eat less of share a small space at the top, and the foods that should be eaten regularly make up the broad base. Both pyramids recomment lots of fruit and vegetables.
This is where Walter Willet's new food guide pyramid starts to change, as weight control makes u pthe base of his pyramid, providing a common sense reminder that a good diet is necessary but not sufficient for good health. His new pyramid also reduced what he believes is a dangerous reliance on carbohydrates and encourages consumers to choose the healthier options in all food groups.
The result is a pyramid with a base of regular physical activity and weight control. One layer up and you will see emphasis on whole-grain, high-fiber carbohydrates and healthy fats (like vegetable oils, avocados and nuts). Lots of fruit and veg is encourgaed, as well as moderate amounts of nuts and legumes. Fish, pourlty and eggs are also accepted. And at the tip you find some traditional nutritional losers, red meat and butter, alongside refined starches and sugars.
Healthy diet and some good exercise will keep us fit and healthy!
