Carbohydrates are foods, which contain
similar ratios of the elements, carbon, hydrogen, and oxygen. The group
consists of gums, cellulose, sugars, and starches. They serve as the body’s
primary fuel source when converted to glucose, a simple sugar used by the body
as a quick source of energy.

Forms Of Carbs
Carbohydrates come in two forms simple and
complex. Simple carbohydrates or simple sugars occur in processed and refined
foods. Sources of simple sugars include refined cane sugar (white table sugar),
honey, fruit, dairy products, and vegetables.
Complex carbohydrates consist a series of
linked simple carbohydrates and fiber. Starchy foods contain complex
carbohydrates. Complex carbohydrate sources include whole grain products,
pastas, rice, cereals, nuts, seeds, beans, legumes, bread, and starchy
vegetables like potatoes, peas, corn, and zucchini.
When considering which carbohydrates provide
the greatest health benefits, complex carbohydrates give more nutritional
benefits. They contain vitamins, minerals, and fiber lacking in simple
carbohydrates. They also provide the body with slow and consistent fuel keeping
insulin levels even and consistent.
Simple sugars cause insulin levels to spike
which can lead to insulin resistance for some people if simple sugars are a
primary carbohydrate source. Insulin resistance has been consistently linked to
patterns of obesity and diabetes.
While the body treats all sugar as fuel,
the way it metabolize them greatly influences their long term effects on the
body.
Low carb diets include a low level of
mostly complex carbohydrates with most calories coming from protein and fat. Recently
low carb diets have become increasingly more popular as people find them to be
so effective for weight loss. In fact, restricting carbohydrates effectively
supports weight loss according to a study described in the September issue of
the Annals of Internal Medicine.
However, the quality of the carbohydrates
consumed is equal in importance to monitoring the amount. The fiber in complex
carbohydrates plays a significant role in supporting heart health as well.
Dietitians recommend consuming 60 to 130 grams of carbohydrates daily.
Protein and fat sources for low
carbohydrate diets need to be lean and healthy. Protein sources include fish,
meat, poultry, eggs, and some non-starchy vegetables. Healthy fat
(monounsaturated and polyunsaturated) sources include unrefined nut, seed and
vegetable oils like sunflower seed oil, olive oil and coconut oil.
For several decades, low carb and low fat
diets received a great deal of endorsement and attention for supporting weight
loss and overall health. It was also unclear which approach provides the most
effective results for weight loss.
A
recent study indicates a low carbohydrate diet works best for weight loss with
the added benefit of decreasing risk factors for developing heart disease.
Both diets allow people to lose weight
effectively, however low carb diets appear to allow people do so with more success.
According to the randomized trial published
in the Annals of Internal Medicine, a small group of obese dieters divided into
two groups, one following a low fat diet and the other a low carbohydrate diet,
found the low carbohydrate group lost more weight during the year long study.
They also showed greater decreases in body
fat and triglycerides, risk factor for heart disease, and increased levels of high-density
lipoprotein (HDL), good cholesterol.
While a low carbohydrate, diet supports short-term
weight loss and heart health, other characteristics of a low carb diet may be
more significant causal factors. The higher amounts of protein and fat allow
dieters to feel full longer which may lead them to eat less in general. Low
carb diets done well also provide fewer calories.
Low-carb
diets must be carefully planned to ensure enough carbohydrates are consumed.
Consuming less than 20 grams of carbohydrates can cause uncomfortable symptoms
including:
·
Bad
breath
·
Fatigue
·
Constipation
or diarrhea
·
Headache
As a primary source of energy, high quality
carbohydrates keep the body healthy and well fueled for daily activities and
functions. Choosing healthy and unrefined carbohydrates as part of a balanced
diet while limiting the amount consumed supports heart health.
Carefully monitor your energy levels and
digestive response while on a low-carb diet and adjust your intake to meet your
nutritional and caloric requirements.
