Why some people have Milk/Lactose-Intolerance

Some of us are consuming cow milk at least once daily with breakfast cereal, then cheese with our burger for lunch and cheese-cake or yogurt or even ice-cream for a snack or desert. But have you ever questioned of where and when we started consuming cow’s milk and for how long adult-humans have been consumingContinue Reading

Sleep Deprivation May Cause Your Afternoon Food Cravings, Leading to Obesity

Short sleep duration, less than 7 hours per night, increases the risk of being obese compared to those who sleep 7-8 hours per night. Previous studies showed this association several times, yet could not show a cause-effect relation due to some strong limitations of those studies. The American Journal of Clinical Nutrition published the latestContinue Reading

Carb Loading

Carb Loading

Carb loading, or muscle glycogen supercompensation, is a process used to increase glycogen storage in the muscles beyond normal levels. It is hoped that this extra storage will then allow athletes to maintain their exercise for a longer period of time before exhaustion starts to kick in. While this is may seem like great news,Continue Reading

Macronutrients

Macronutrients are the dietary nutrients that supply energy, including fats, carbohydrates, and proteins. Nutrients are substances needed for growth, metabolism, and for other body functions. Since “macro” means large, macronutrients are nutrients needed in large amounts.

Fats have four forms: saturated fats, monounsaturated fats, polyunsaturated fats, and essential fatty acids. Carbohydrates contain both starches and sugars. Fat is found in meat, poultry, nuts, milk products, butter, margarine, oils, lard, fish, grain products, and salad dressings. Many people correlate fat intake with weight gain, but fats are essential for survival.  We need fat for energy, growth, cushioning for organs, and maintaining cell membranes.

Carbohydrates are mainly found in starchy foods (e.g. grain and potatoes), milk, yogurt, and fruits. Other foods like vegetables, beans, nuts, seeds and cottage cheese contain carbohydrates, but in lesser amounts. Carbohydrates are the body’s main source of fuel and are easily used for energy in our bodies.  Carbohydrates are also stored in the muscles for later use.

Protein is made up of amino acids. Protein is found in meats, poultry, fish, meat substitutes, cheese, milk, nuts, legumes, and in smaller quantities in starchy foods and vegetables. Protein is essential for growth, tissue repair, making hormones and enzymes, and immune function. Some amino acids are essential (meaning we need to obtain them from our diets) and others and nonessential (meaning the body can make them). Protein from animal sources contain all the essential amino acids we need. However, plant sources do not contain all the essential amino acids.
