Coconut oil has a sweet taste that lends distinct flavor to foods, and it contains several saturated fats—something the 2010 Dietary Guidelines for Americans suggest we eat less of. That is because eating saturated fats has been linked to atherosclerosis (“hardening of the arteries”) and increased risk of heart disease.
Although coconut oil is highly saturated, it has different types of saturated fats. One of these—lauric acid—is regularly touted as having performance benefits. Lauric acid is referred to as a “medium chain fatty acid” (MCFA), and the body processes MCFAs differently than it does “long chain” fatty acids (LCFAs). Importantly, MCFAs are digested more rapidly than long chain fatty acids, so they are quickly absorbed and available as an energy source. Some research suggests MCFAs might help to optimize and maintain glycogen stores, thus extending endurance performance. Not only that, MCFAs are less likely than other fats to be stored as fat—a plus if you’re concerned about weight control. The performance claims surrounding MCFAs and coconut oil have not held up, and claims about their weight loss benefits need more research.
The American College of Sports Medicine and the Academy of Nutrition and Dietetics joint guidelines for Nutrition and Athletic Performance indicate that MCFAs do not provide any performance benefit. To date, only two studies have shown improvements in performance. On the other hand, MCFAs have been shown to increase the body’s use of “fats” as fuels, reducing food intake, so such products may promote weight loss. There just isn’t enough information available to make any scientific conclusions.
If you choose to eat coconut oil, do so in moderation for its unique flavor and texture, because its health and performance benefits are still open for consideration.
Solid fats are solid at room temperature, come mainly from animal products, and are high in saturated or trans fats. Examples are butter, milk fat, cream, stick margarine, shortening, and beef, chicken, and pork fat. Some saturated fats increase blood cholesterol levels in the body. Oils are liquid at room temperature, and come from many different plants, and are good sources of heart healthy unsaturated fats. Examples are olive oil, canola oil, safflower oil, corn oil, soybean oil, and peanut oil. Coconut oil, palm oil, and palm kernel oil are high in saturated fats and are considered solid fats. When using fats, replacing solid fats with unsaturated oils will provide essential nutrients to the diet and help lower blood cholesterol levels.

A Military Times article reports on a recent study of more than 30 of the most popular dietary supplements (in capsule form) sold on military bases analyzed to determine their caffeine content. Of the 20 supplements that listed caffeine as an ingredient on their labels, six did not specify the amount. These same six contained high amounts of caffeine (210-310 mg per serving)—three or more times the amount permitted by law in soft drinks. Five others revealed significantly different amounts—some more, some less—than the quantity stated on the product label.
Consuming too much caffeine can result in health issues. And if you don’t know how much is in the supplement you’re taking, it could be easy to overdo it if you also drink coffee or energy drinks. Visit the Operation Supplement Safety (OPSS) FAQ on caffeine for additional information.
Do you think nutritious foods are expensive? Think again. A cost-per-calorie comparison of the prices of fat- and sugar-laden convenience foods to the prices of nutritious whole foods showed the convenience foods coming up short.
A study conducted in a low-income area of Baltimore, Maryland, revealed that a diet based primarily on convenience foods from fast-food restaurants cost 24% more than a diet based on whole foods purchased in a grocery store. Of course, prices vary between seasons and geographic locations, but the message was clear: Don’t be fooled by “dollar menus” and “meal deals.”
Here are some more tips to stretch your food dollars:
- Meats: Buy lean cuts of meat, poultry, and fish on sale and freeze for later use. (Use freezer wrap for long-term storage.)
- Fruits and vegetables: Not only are fruits and vegetables less expensive when they are in season, the ones in season are freshest and have the best flavor. Take advantage of lower prices on apples in autumn, kale in winter, peas in spring, and strawberries in summer, for example.
- Processed foods: Cereal, low-fat pasta sauces, and other slightly processed foods can be healthful choices, but name brands can be expensive. Store brands are often excellent quality and typically cost less.
- Snacks and beverages: Opt for inexpensive (and healthy) snack choices such as popcorn, dried fruit, or peanuts. Milk and juice provide needed nutrients without the “empty” calories found in sodas and beer.
- Coupons, coupons, coupons: They’re like free money.
With a little time and planning you can provide your family with healthy, nutritious meals and save money.
The Food and Drug Administration (FDA) is investigating five deaths and a non-fatal heart attack that may be linked to Monster Energy drinks. The FDA has pointed out that while the investigation is going on, it does not mean that Monster Energy drinks caused these adverse events, which were reported to the FDA over a span of eight years. Other adverse event reports have been associated with consuming the energy drinks. Read the New York Times article here, as well as this one from NBC News.

In the war against childhood obesity, senior military leaders are taking a stand in the name of national security. The retired generals and admirals of “Mission: Readiness” are doing their part to combat childhood obesity by calling on Congress to remove junk food and high-calorie drinks from schools by adopting the Institute of Medicine standards for what can be served in schools, increasing funding for more nutritious meals, and supporting the development of public health interventions. The group is concerned that current school policies and lack of high nutritional standards are leading to unhealthy food choices in the form of vending machine snacks and sugary drinks. As much as 40% of children’s caloric intake occurs at school, so clearly schools have an important role to play. Retired U.S. Army General Johnnie E. Wilson points out that “We need America’s service members to be in excellent physical condition because they have such an important job to do.” The most recent report by the Mission: Readiness organization estimates that 27% of young Americans are still too fat to fight and not healthy enough to serve their country. In an analysis of military standards, being overweight was the leading medical reason for being rejected from the military between 1995 and 2008. While these military leaders may be fighting for your kids, the real battle begins at home. Encourage healthy eating and lifestyle behaviors by staying fit as a family.

SuperTracker, a free online tool released in 2011, allows users to assess daily healthy food and lifestyle choices and track their progress. With the newly added feature, users will be able to tailor their unique needs.
About half of all military personnel use some dietary supplements, and military women most commonly use weight-loss supplements. But is there a place for dietary supplements in enhancing women’s health? Dietary supplements, by definition, are intended to “supplement the diet” and can contain a dietary ingredient such as a vitamin, mineral, herb or other botanical, amino acid, or combinations of these and/or other substances or constituents intended to be consumed by mouth.
Active women may require more nutrients, but vitamin and mineral needs normally can be met by eating a variety of nutrient-rich foods. The Dietary Guidelines for Americans focus largely on the recommendation that nutrient-dense foods and beverages—such as fruits, vegetables, whole grains, low-fat dairy products, lean meats and poultry, eggs, nuts and seeds—can provide all the nutrients needed by most everyone. These recommendations are based on research that shows a varied, healthy diet lowers the risk of most diseases.
Some dietary supplements have been found to be beneficial for women’s health, such as folic acid, iron, and calcium. Folic acid, a B vitamin involved in the production of new cells in the body, has been shown to help prevent birth defects. Women who are thinking of becoming pregnant or are pregnant should take a supplement that includes 400 micrograms of folic acid per day. Fortified foods such as green, leafy vegetables, enriched whole grain breads, flour, pasta, rice, and most ready-to-eat cereals also contain folic acid. Adolescent girls, women of childbearing age, and especially pregnant women also need more iron, which is a mineral involved in the transport of oxygen in the body. Women in these groups should choose iron-rich foods, particularly red meat, fish, and poultry, as well as iron-fortified foods. When iron levels are low, symptoms may include feeling extra tired and weak, along with a decrease in immune function. A healthcare provider or dietitian can determine the need for supplementation if diet alone cannot maintain iron levels or for those who have iron-deficiency anemia. Calcium is an important mineral that helps maintain strong bones, healthy teeth, and proper functioning of the heart, muscles, and nerves. All women should strive to get their calcium from foods such as low-fat milk, yogurt, cheese, dark-green, leafy vegetables, and foods such as orange juice and soy milk that have been calcium-fortified. Those who may need more should discuss calcium supplement options with a dietitian, since there are many forms available and it is important to determine how much and which kind is suitable for your particular needs.
Some dietary supplement products marketed for weight loss are targeted toward women. Do they work? According to the Food and Drug Administration (FDA), some weight-loss supplements contain hidden prescription drug ingredients. For additional information, see Operation Supplement Safety’s (OPSS) “Are there any safe supplements to help me lose weight?” Furthermore, women looking to enhance their performance may turn to dietary supplement products. OPSS has additional resources for competitive athletes to search for particular products that are certified, as well as helpful red flags on what to avoid.
Some women’s nutrient needs differ from those of men, and they can vary over the course of a lifetime. From adolescent girls, to women of childbearing age, to women over 50, these needs change based on the demands of the physiological changes that occur in the body. One thing is certain: A variety of nutritious food is really the spice of life and should be the basis for fueling all of life’s stages.
