"Holistic nutrition. " You may not know the term, but you've surely heard its claims. Among other things, holistic nutritionists (or HNs, as they call themselves) may teach that fluoride and pesticides are lethal, that most diseases and detrimental behaviors are diet-related and that many people would benefit from taking numerous supplements. I've read plenty of articles by HNs in which they assert that they are disparaged by mainstream medicine and warn you not to trust modern medicine.

With at least two flus and plenty of colds, coughs and sore throats circulating this season, some Americans are turning to zinc to ward off viruses. Lozenges, supplements and nasal sprays that contain the mineral claim to boost immunity, and there is some evidence that they might do so. In an effort to stay well, though, we might be making ourselves sick.

Where did we get the notion that "an apple a day keeps the doctor away"? Why is it important to get vitamin E in our diets? What are "recommended daily allowances," and why do they matter? Proper nutrition and food intake are absolutely essential to help keep our bodies on the go. The proper balance of fruits, vegetables, breads, meat and dairy products is of vital importance for healthy teeth, blood vessels and muscles.

About a month ago we gave nutritional makeovers to two families -- with an assist from Emily Ventura, a nutrition expert and research associate at the USC Childhood Obesity Research Center at the Keck School of Medicine. Now we're checking back in. Duncan MacLeod and Rafael Navarro The Los Angeles residents were partial to calorie- and fat-laden lunches, regular fast-food meals and snacking that sometimes continued late into the night. Their makeover included advice to eat a more plant-based diet, maybe frequenting local farmers markets for top-notch fresh produce, and to cut back on diet sodas.

Full-fat, low-fat or skim? Used to be, there weren't many choices to make over what to pour on your cereal. But the number of alternatives to cow's milk -- soy, goat's, hemp milk, more -- has steadily grown. Each has its fans: those who swear by goat's milk's creamy texture or who love almond milk's subtle, nutty flavor. But when it comes to nutrition, there's no clear winner. Cow's milk is a good source of protein but can be high in saturated fats. Hemp milk offers little protein but is rich in certain essential fatty acids.

Move over, omega-3s . There's a new fatty acid in town that might make you healthier. Something more closely associated with creamy pleasure than with fish burps. Trans-palmitoleic acid, a fatty acid that circulates at higher levels in the blood of those who consume lots of full-fat dairy products, may protect against diabetes, according to a study published Monday in the Annals of Internal Medicine . That surprising finding may fly in the face of much nutritional advice that warns us against consuming too much whole milk, cheese or other sources of animal fat. But it comes from a study of 3,736 adults participating in the long-running Cardiovascular Health Study . It also proceeds from a suspicion that researchers have had for a while, but found difficult to prove: that the fatty acid palmitoleate, which humans produce in their liver and fat, and consume in dairy fats, may play a complex role -- beneficial and harmful -- in regulating metabolism . By measuring just the palmitoleate that came from consumption of dairy fats, researchers were able to discern the side of this fatty acid that may contribute to good health.
