Foods, nutrients or whole diets: effects of targeting fish and LCn3PUFA consumption in a 12mo weight loss trial.

BACKGROUND: There is some evidence in the literature that emphasising fish consumption may assist with weight loss. The aim was to assess the effects of advice to consume 2 fish meals per week in a weight loss diet. METHODS: A parallel randomised placebo-controlled trial was conducted in 118 obese Australian adults (mean BMI ± SD 31.3 ± 3.5 kg/m2; mean age ± SD 45 ± 10 y; 28% male). Participants received low calorie dietary advice+placebo (1 g olive oil; CONTROL), low calorie dietary advice emphasising fish+placebo (Fish), or low calorie dietary advice emphasising fish diet + LCn3PUFA supplements (Fish+S). Individualised advice targeted 2 MJ energy deficit (30%E fat, 45%E carbohydrate and 25%E protein) with or without two servings (180 g) fatty fish/wk. RESULTS: All groups lost weight at 12 months (CONTROL -4.5 kg vs. Fish -4.3 kg vs. Fish+S -3.3 kg; p<0.001) and percentage body fat ( CONTROL: -1.5% vs. Fish: -1.4% vs. Fish+S: -0.7%; p<0.001) but there were no significant differences between groups. Cardiovascular disease risk factors changed as expected from weight loss. CONCLUSIONS: Advice to consume 2 fish meals per week did not enhance the effects on weight loss of a healthy low calorie diet. TRIAL REGISTRATION: ACTRN12608000425392.

Development of a mild traumatic brain injury-specific vision screening protocol: a Delphi study.

Although traumatic brain injury (TBI) can happen to anyone at any time, the wars in Iraq and Afghanistan have brought it renewed attention. Fortunately, most cases of TBI from the recent conflicts are mild TBI (mTBI). Still, many physical, psychological, and social problems are associated with mTBI. Among the difficulties encountered are oculomotor and vision problems, many of which can impede daily activities such as reading. Therefore, correct diagnosis and treatment of these mTBI-related vision problems is an important part of patient recovery. Numerous eye care providers in the Department of Veterans Affairs, in military settings, and in civilian practices specialize and are proficient in examining patients who have a history of TBI. However, many do not have this level of experience working with and treating patients with mTBI. Recognizing this, we used a modified Delphi method to derive expert opinions from a panel of 16 optometrists concerning visual examination of the patient with mTBI. This process resulted in a clinical tool containing 17 history questions and 7 examination procedures. This tool provides a set of clinical guidelines that can be used as desired by any eye care provider either as a screening tool or adjunct to a full eye examination when seeing a patient with a history of mTBI. The goal of this process was to provide optimal and uniform vision care for the patient with mTBI.

Cereal grains, legumes, and weight management: a comprehensive review of the scientific evidence.

There is strong evidence that a diet high in whole grains is associated with lower body mass index, smaller waist circumference, and reduced risk of being overweight; that a diet high in whole grains and legumes can help reduce weight gain; and that significant weight loss is achievable with energy-controlled diets that are high in cereals and legumes. There is weak evidence that high intakes of refined grains may cause small increases in waist circumference in women. There is no evidence that low-carbohydrate diets that restrict cereal intakes offer long-term advantages for sustained weight loss. There is insufficient evidence to make clear conclusions about the protective effect of legumes on weight.
