Clinical Research Studies of Raw Food Diets

Here are results noted from a few of the studies done on the benefits of raw food diets:

Nutrition and Energy

Raw foods are packed with nutrients and can provide a significant amount of energy for our body’s needs. For example, dates contain the highest amount of antioxidants among the dry fruits that are more commonly consumed raw. Antioxidants clear the free radicals that destroy normal cells and alter the functioning of tissues and organs. Dates contain significant amount of minerals such as selenium, copper, potassium, and magnesium and vitamins including: C and the B-complex vitamins. Dates are also good sources of energy – one study showed that 100gm of dates (without the seed) provide about 314 kilocalories of energy. Another study that evaluated the energy values in vegetables reported that vegetables were significant sources of energy with the energy values ranging from 281.4 to 303.9 kcal/100 g. This tells us that fruits and vegetables can provide most of the energy requirements in the human body.

Heart Health

Most of us know that eating junk foods and foods high in fats have a direct negative effect on the heart and can lead to heart disease and eventual failure. However, a diet that includes living raw foods such as fruits, nuts, seeds, and sprouted grains and beans significantly reduces the risk of heart disorders. Studies conducted on the relation between consumption of raw fruits and vegetables and the incidence of heart disorders concluded that an increased consumption of fruits and vegetables significantly reduced this risk. It’s also noted that the levels of ‘bad’ cholesterol (HDL) decreased while the ‘good’ cholesterol (LDL) increased. This control of cholesterol prevents the occurrence of various heart disorders associated with high cholesterol levels.

Dietary Fiber for Health

Raw foods high in fiber offer many benefits. These include: lowering the blood cholesterol levels, lowering the risk of heart disease, improving blood glucose control, reducing risk of cancers and improving gastrointestinal functions. Americans eat about half of the recommended daily dietary fiber. Adding more raw foods to your diet can easily increase fiber intake.

A Great Way to Lose Weight

Many studies have concluded that a raw foods diet significantly reduces the body weight and the body mass index (BMI) scores. One study conducted on African American women noted that there was a significant reduction in weight and BMI scores when these women were on a raw food diet for 3 months. Another study conducted for about 7 months duration reported that the subjects involved in the study lost up to 3.8 kilos while on a raw diet.

Look Young with Raw Foods

As we age the constructive body processes begin to slow down and destructive processes take over. Phytonutrients and antioxidants in raw foods counteract these destructive processes. The antioxidants prevent the destruction of cells and help the skin to retain its firmness and youthful glow. The phytonutrients are also known to help prevent and counteract disorders of the skin and cancers in general.

Smoking and Alcohol Cessation

An interesting discovery was made during a study to observe the benefits of raw foods on body weight and blood pressure. While there was an expected reduction in the body weight and blood pressure levels in the individuals involved in the study - another astonishing factor was noted. About 80% of those involved in this study reported that they had stopped smoking and drinking alcohol completely by the time the study concluded! It’s possible the phytonutients present in the raw foods have a cleansing effect on the body that led to this happening.
