26 Jul 2017 --- Eating foods that are included in either the Mediterranean or MIND diets has been linked to a lower risk for memory difficulties in older adults, according to a study published in the Journal of the American Geriatrics Society.

The Mediterranean diet, rich in fruit, vegetables, whole grains, nuts, olive oil, and fish, has been proven to have vascular and anti-inflammatory benefits and may be neuroprotective, according to the study. Neuroprotective diets are associated with better cognitive function: the Health and Retirement Study. Processed foods, fried and fast foods, snack foods, red meat, poultry and whole-fat dairy foods are infrequently eaten by those following the Mediterranean diet.

MIND stands for Mediterranean-DASH Intervention for Neurodegenerative Delay. It’s similar to the DASH (Dietary Approaches to Stop Hypertension) diet as well as the Mediterranean diet. It includes 15 types of foods. Ten are considered “brain-healthy” food groups: green leafy vegetables, other vegetables, nuts, berries, beans, whole grains, seafood, poultry, olive oil and wine. Five are considered unhealthy: red meat; butter and stick margarine; cheese; pastries; sweets; and fried or fast foods.

The study notes that dementia is a major cause of death and disability in older Americans, and therefore there is a great deal of interest in identifying lifestyle approaches like the Mediterranean and MIND diets for prevention of cognitive decline with aging.

For the study, researchers examined information on the diets of 5,907 older adults who participated in the Health and Retirement Study. The participants filled out questionnaires about their eating habits. Researchers then measured the participants' cognitive abilities, mostly focusing on their memory and attention skills.

When the researchers compared the diets of participants to their performances on the cognitive function tests, they found that older people who ate Mediterranean and MIND-style diets scored significantly better than those who ate less healthy diets. In fact, older people who ate a Mediterranean-style diet had 35 percent lower risk of scoring poorly on cognitive tests. Even those who ate a moderate Mediterranean-style diet had 15 percent lower risk of doing poorly on cognitive tests. The researchers noted similar results for people who ate MIND-style diets.

This study suggests that “greater adherence to the Mediterranean diet and MIND diet was independently associated with better cognitive function,” according to the researchers. What's more, older adults who followed these healthy diets had lower risks of having cognitive impairment in later life, they note.

Ultra-processed foods linked to heightened risk of cancer: major BMJ study

15 Feb 2018 --- Although processed foods have long been thought to be significantly less healthy than non-processed foods, an observational study published yesterday in BMJ has added some stark figures to the link between ultra-processed foods and the risk of cancer. The study concluded that a 10 percent increase in the proportion of ultra-processed foods in the diet is associated with increases of 12 percent in the risk of overall cancer and 11 percent in the risk of breast cancer.

Façade? British Nutrition Foundation questions benefit of skin beauty nutraceuticals

14 Feb 2018 --- Although there is a growing market for orally consumed beauty supplements that promise “youthful,” “firm” and “glowing” skin, the evidence to support some of the ingredients used in these popular, and often costly, products is limited. This is according to a review of published research conducted by the British Nutrition Foundation (BNF). The review concludes that nutraceuticals for skin may not add further benefit to the effects already obtained from a healthy diet.

The debate is over: Protein supplements “significantly” benefit muscle mass

09 Feb 2018 --- Dietary protein supplements do significantly improve muscle strength and size when taken by healthy adults who lift weights, say McMaster scientists who analyzed dozens of research studies. According to the researchers, their analysis puts to rest any debate on whether or not such supplementation is effective. However, the effects are not as big as some supplement companies would have you believe, cautions the senior author on the paper, Stuart Phillips, a professor of kinesiology at McMaster University.
