All of the identified studies focused on LNSs for pregnant and lactating women through antenatal care–based and –affiliated delivery platforms (97–101). These studies relied on antenatal care to recruit mothers but delivered the intervention through home visits. There was no evidence evaluating use of LNSs for women who were not pregnant or lactating. The majority of studies evaluating LNS interventions involved children with severe or moderate acute malnutrition. Although LNS supplementation could be an intervention to provide essential nutrients to women and girls, it is expensive. Filling energy gaps using local foods or other commodities can often be done at a lower cost (97). LNS supplementation should be limited to contexts in which cheaper, more sustainable solutions are not available.
Although canola oil appears to be good for the cardiovascular system, two Harvard studies have raised concerns that ALA might be bad for the prostate. In 1993, the Health Professionals Follow-up Study of 47,781 men published a major evaluation of dietary fat and prostate cancer. It found that saturated fat from animal sources such as red meat and whole-fat dairy products was linked to a 2.6-fold increase in prostate cancer. But the study also provided some disquieting news about ALA: Men who consumed the most ALA were 3.4 times more likely to be diagnosed with prostate cancer than those who had the lowest dietary intake.
Everyone seems to have food allergies these days, but in fact, such allergies are rare. According to the National Institute of Allergy and Infectious Diseases, while one in three adults think they have a food allergy or modify their family's diet, only about four percent do. A food allergy is an abnormal immune-system response to certain foods (most commonly, fish, shellfish, peanuts, other nuts and eggs). Symptoms can include hives, rashes, nasal congestion, nausea, diarrhea and gas. However, symptoms of food intolerance—such as intestinal distress—may mimic those of a food allergy. You may want to talk to an allergist about diagnosis and treatment. Whether you have food allergies or intolerance, you will need to develop a diet that fits your needs and avoids foods that trigger a reaction.
Energy and protein supplementation was most often associated with weight gain of women, and often targeted pregnant women with suboptimal weight. For pregnant women, energy and protein supplementation modestly increased maternal weight (86–90). Other maternal outcomes were not frequently reported, and were often secondary objectives of protein-energy supplementation interventions (33, 88). Many studies reported on infant health outcomes, including reductions in low birth weight and preterm births (19, 89–91). Adequate energy and protein intake was also relevant for interventions targeting the prevention of excessive gestational weight gain of overweight and obese pregnant women. These interventions restricted dietary energy intake of overweight women during pregnancy and resulted in reduced excess weight gain during pregnancy but had no impact on pregnancy-related hypertension and pre-eclampsia (19, 88).
It’s been a while since I’ve picked up any of these, but when I did, the messages weren’t nearly as body-positive. In fact, a quick perusal of other Shape magazine covers from the 1980s (I was probably still reading Seventeen then, but still) shows a bunch of celebrity cover models who would like you to get off the couch immediately, with demands like “Get Strong!” and “Push For Fitness!” Also suspect: “How To Think And Eat Like A Thin Person” and “Is Food Your Lover? How To End The Affair.”
