Some History Behind the DASH Diet

An article on the life and times of George Bray:

“With unparalleled resources to support basic science and clinical research, George [Bray] led research teams at Pennington Biomedical that have had a major influence on modern assumptions about the biology of obesity. The first major study in this category was the Dietary Approaches to Stop Hypertension, or DASH, study. Pennington Biomedical and four other nutrition research leading centers initiated a feeding study that tested dietary patterns for effects on blood pressure. Given the hypothesis that magnesium, calcium, potassium, and fiber would have salutatory effects on blood pressure, the study tested increasing consumption of fruits and vegetables and low-fat dairy products as sources of these factors. It produced clinically significant reductions of blood pressure in men and women of all ethnic groups (9). Because the dietary pattern translates into an easily understood public health message, the DASH diet has been considered one of the best diets in America and is recommended by most national guidelines.”

Being overweight or obese linked to increased risk of eight more cancers 

From MedicalNewsToday:

“A new study strengthens the link between obesity and cancer, after identifying a further eight cancers that are more likely to develop with excess weight, including stomach, pancreas, and liver cancers.

Researchers have associated excess weight with a further eight cancers.

But there is some good news; researchers say losing the excess weight and preventing further weight gain can help lower the risk of these cancers.”

*   *   *

“The researchers found sufficient evidence to suggest excess weight can increase the risk of eight cancers, in addition to the five already identified. These cancers include:

Gall bladder cancer
Liver cancer
Meningioma – a form of brain tumor
Multiple myeloma – a type of blood cancer
Ovarian cancer
Pancreatic cancer
Thyroid cancer”

American Heart Association Recommends U.S. Children Reduce Sugar Consumption by Two Thirds of Current Levels

 

“Children and adolescents should consume no more than 25 grams of added sugars a day, according to a new scientific statement from the American Heart Association (AHA).

The statement in Circulation addresses the health concerns in young children and adolescents as a result of consumption of added sugars, such as an increased risk of cardiovascular disease, hypertension, obesity, and insulin resistance leading to type 2 diabetes.”

Family, not friends, lowers death risk in old age 

I thought close friends would also improve longevity. But not this time:

“It is no secret that being around friends and family in older age can benefit health; loneliness among seniors has been linked to increased risk of depression, heart disease, and more. According to a new study, however, only family can lower mortality risk in later life.

Having more family and feeling closer to relatives in later life may improve longevity.Lead author James Iveniuk, of the Dalla Lana School of Public Health at the University of Toronto, Canada, and colleagues found that older adults who have more family members and who are closer to their family have a lower risk of death, though the same link could not be made with friends.”

Can we target cancer with ketogenic diets? Can you help?

Richard David Feinman is raising money for ground-breaking research that may help cure cancer. I think it’s a worthy cause.

Dr. Feinman writes:

“We have a good deal of enthusiasm in the keto/paleo/low-carb community. We have the real sense that we can we use carbohydrate restriction to take advantage of the characteristic metabolic features of cancer — inflexible reliance on glucose. Enthusiasm may have outstripped the data and several groups are trying to fill the gap. The barrier rests with the difficulty for anybody to obtain funding from NIH or other government or private agencies and the long-standing resistance to low-carbohydrate diets makes it particularly difficult.We have some good experiments and a dedicated technician and we can efficiently use limited funds. Your backing can help. A $15 donation gets us several days of supplies for the in vitro experiments that provide the biochemical underpinnings for attacking cancer in the clinic. Our project at experiment.com provides background, a place for discussion and reports from the lab.

The current metabolic point of view in cancer — emphasizing flexibility of fuel choices —  derives from renewed interest in the Warburg effect. Warburg saw that many cancer cells were producing lactic acid, the product of glycolysis. In other words, the tumors were not using the more efficient aerobic metabolism even when oxygen was present in the environment. The tumor cell’s requirement for glucose suggests the possibility of giving the host an advantage by restricting carbohydrate and offering ketone bodies as an alternative fuel.”

Potatoes Don’t Cause Diabetes, Obesity, or Cardiovascular Disease

…at least according to researchers in Denmark who did a review of the scientific literature.

“The identified studies do not provide convincing evidence to suggest an association between intake of potatoes and risks of obesity, type 2 diabetes, or cardiovascular disease. French fries may be associated with increased risks of obesity and type 2 diabetes although confounding may be present. In this systematic review, only observational studies were identified. These findings underline the need for long-term randomized controlled trials.”

Mediterranean and Paleo Diets May Reduce Incidence of Colon Polyps

Colon cancer is one of several cancer types reduced by the Mediterranean diet. The diet may do so by preventing colon adenomas (aka colon polyps), which are precursors to cancer. Click the link at bottom for the full scientific report. A snippet:

“Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second-leading cause of cancer mortality in the United States. Rapidly increasing incidence rates in previously low-incidence populations in urban China and Japan and among male Polynesians in Hawaii have coincided with the adoption of a more westernized lifestyle by those populations. These changing incidence rates, along with studies of immigrant populations, point to a strong influence of diet and other lifestyle factors on CRC risk.”
