Question: As an athlete, I am craving salt. Why? Should I give in to the craving?
Salt cravings can be linked to a lot of things, including stress, lack of sleep and even premenstrual syndrome, but since you’re athletic, most likely they are because of the loss of minerals — including sodium — from sweating.
Salt cravings also can be linked to dehydration, especially if they are accompanied by dizziness, thirst, headache, irritability or cramps. If you don’t sweat a lot, you can probably replace those minerals and quench your cravings with tap water alone. If you sweat more or if you’re an endurance athlete, however, drink an electrolyte-enhanced beverage, eat a (healthy) salty snack or sip a broth-based soup to help replace your deficit.
Spotlight On: BPA
Bisphenol A (BPA) is an industrial chemical used in the manufacture of resilient plastics used for food containers, toiletries, sports equipment, household electronics and the anti-corrosive lining inside cans of food.
Many experts claim that BPA exposure is harmful: When ingested, it can mimic the structure and function of estrogen or can bind to estrogen receptors, negatively impacting reproduction, fetal development, energy levels and cell repair. High levels of BPA also have been linked to high blood pressure, obesity, heart disease and Type 2 diabetes.
Completely eradicating BPA exposure may be impossible because of its widespread use, but limit it whenever possible. Emphasize whole foods, avoid packaged and canned goods, use glass bottles instead of plastic, choose BPA-free plastic toys and products, and never microwave food in plastic containers; BPA and other chemicals can leak into food when heated.
Nutrition Myth Bustin’
True or False?: Combining carbs and protein in a meal is bad for digestion.
False. Lately, there is a theory that combining carbs and protein in a single meal “confuses” your digestive system, and that since your body is not equipped to digest mixed nutrients, it could cause weight gain. However, your body is specifically prepared for this kind of multitasking and releases all kinds of digestive enzymes at the same time that break down carbs, fats and protein — even if you didn’t eat all those macros in a single meal. Besides, most single foods contain a mix of two or more macros, so neither you — nor your body — needs to worry about choosing what to digest.
