AJCN Apr, 2011 -DETAILS-
FEATURE: This month Science featured an article on free will. I had an interesting exchange about the nature of consciousness and free will. Why consciousness has evolved suggests to me that we may have free will, although I do not understand how it could function in a determinist universe. Read the exchange here.
AJCN This month:
Anti-inflammatory signals are sent by: Exercise; MUFAs and PUFAs; omega- 3 fats, HDL; plant polyphenols; vitamin D
1. Exercise prevents weight gain, chronic disease, and premature death in study of almost 300,000 men and women
2. Replacing saturated fats with polyunsaturated fats reduces risk for heart disease - Current dietary recommendations advise reducing the intake of saturated fatty acids (SFAs) to reduce coronary heart disease (CHD) risk...the risk of CHD is reduced when SFAs are replaced with polyunsaturated fatty acids (PUFAs). In populations who consume a Western diet, the replacement of 1% of energy from SFAs with PUFAs lowers LDL cholesterol and is likely to produce a reduction in CHD incidence of ≥2–3%.
3. We tested whether raising plasma free fatty acids by using a high-fat, low-carbohydrate diet [like the Atkin's diet] results in alterations in heart and brain in healthy subjects. ..Raising plasma free fatty acids decreased cardiac function and reduced cognition, which suggests that a high-fat diet is detrimental to heart and brain in healthy subjects.
4. Acetyl-Carnitine intake (2 g daily) benefits nerve and mitochondrial health - Patients with hepatic encephelopathy treated with ALC showed a decrease in the severity of both mental and physical fatigue and an increase in physical activity.
6. Low carb diet [like Atkins] increases risk of diabetes - A score representing a low-carbohydrate diet high in animal protein and fat was positively associated with the risk of T2D in men. Low-carbohydrate diets should obtain protein and fat from foods other than red and processed meat.
7. The prevalence of obesity have tripled since 1970, as has energy intake. Dietary interventions should focus on decreasing energy intake and potentially by substituting protein for fat or carbohydrates.
9. Fetal brain, immune system, and proper birth weight all developed from proper fish oil intake by mother - An enhanced maternal-fetal n−3 PUFA status was associated with lower childhood adiposity.
10. Breastfeeding was shown to be related to a lower risk of obesity (4–7), less diabetes mellitus (8), and lower blood pressure in childhood...The duration of exclusive breastfeeding in infancy is related to properties of the carotid arterial wall at the age of 5 y, as shown by the greater CIMT in children who were exclusively breastfed for 3 to 6 mo.
11. A low-intensity behavioral intervention during pregnancy reduced excessive gestational weight gains in normal weight (NW) women and prevented postpartum weight retention in NW and Overweight/Obese women. The intervention included one face-to-face visit; weekly mailed materials that promoted an appropriate weight gain, healthy eating, and exercise; individual graphs of weight gain; and telephone-based feedback.
