1. Get the D and Dairy - Calcium for prevention of weight gain, cardiovascular disease, and cancer. - Recent randomized trials and meta-analyses have provided important new knowledge about the health aspects of dietary calcium that goes far beyond its role in bone and dental health. vitamin D and calcium supplementation significantly reduces the risk of total, breast, and invasive breast cancers by 14–20% over 10 y compared with placebo and reduced the risk of colorectal cancer by 17% in women who were not taking these supplements at baseline. it is interesting that intake of high amounts of dairy products, despite high saturated fat contents, seems to protect against cardiovascular disease (5), diabetes, and colonic cancer (6). dietary calcium may have a direct effect on reducing body fat stores. A recent meta-analysis of RCTs that involved ∼600 overweight and obese individuals from 7 trials found that dietary calcium supplementation of ∼1000 mg produced a weight loss and fat loss of ∼1 kg over 6 mo and had a greater effect in pre- than in postmenopausal women (7).
2. n−3 PUFAs are beneficial to fight cancer, recover from surgery, and survive duing critical care. - Clinical antiinflammatory effects of n−3 FAs have been documented in several chronic inflammatory conditions including rheumatoid arthritis and inflammatory bowel diseases. This review shows the beneficial effects of n−3 FA supplementation in cancer, surgical oncology, and critical care patients.
3. Veggies build better lungs - A higher dietary intake of carotenoid-rich foods and higher circulating concentrations of carotenoids have been associated with better lung function. Serum carotenoids include β-cryptoxanthin, α-carotene, β-carotene, lutein/zeaxanthin, and lycopene. Higher carotenoids maintained healthier lung function over 15 years.
6. Supplement users have better diets, but may get excessive calcium, iron, zinc, and magnesium. Dietary supplement use is extensive in US adults. Individuals who used mineral-containing dietary supplements had higher mineral intakes from food sources in the diet than did nonusers. For all minerals examined, and particularly for calcium and magnesium in men and women and iron in women, supplement use decreased the prevalence of intake inadequacy for each respective mineral; however, supplements contributed to risk of potentially excessive intakes for calcium, iron, zinc, and magnesium.
7. Hoodia is dangerous - Extracts from Hoodia gordonii have been shown to decrease food intakes and body weights in animals...the consumption of H. gordonii purified extract for 15 d appeared to be associated with significant adverse changes in some vital signs and laboratory parameters. HgPE was less well tolerated than was the placebo and did not show any significant effects on energy intakes or body weights relative to the placebo.
8. Heavy drinking is associated with gastric cancer - But light and moderate consumption of alcohol was not relevant.
9. Adolescents are more suseptible to increased portion sizes - We measured trends in portion sizes (kcal, g, and mL) of selected foods [sugar-sweetened beverages (SSBs), salty snacks, desserts, French fries, burgers, pizzas, and Mexican fast foods] and energy intake (kcal) at eating occasions. The group of non-Hispanic African Americans and Hispanics and individuals with a lower education represents key concerns for public health policies.
10. The quality and monetary value of diets consumed by adults in the United States - It costs more to eat decent food. Higher diet cost was strongly associated with consuming more servings of fruit and vegetables and fewer calories from solid fat, alcoholic beverages, and added sugars.
11. In low and middle income nations, the poor stay thinner - Obesity in developing countries is associated with higher incomes.
