#MACRO NUTRIENTS MEANING TRIAL#

Foods that would be considered rich sources of fat would be oils, butter, nuts, and seeds. These foods can also provide fats and proteins but the amounts/ratios can vary. Foods that provide the majority of calories from carbohydrates are fruits, beans, starchy vegetables, beans, grains, and dairy.

Common protein-rich foods are chicken, fish, eggs, turkey, beef, pork, beans, and shellfish. For example, avocados contain a large amount of fat per ounce, and while there are a small number of carbohydrates found in them as well, we do not categorize it as a “carbohydrate”, it is considered a “fat-rich” food. You have probably heard someone say a particular food is “rich” in calcium, iron, or fat. A food “rich” in something provides a majority or large portion of that nutrient. We will typically categorize our foods by the type and amount of macronutrients present. Proteins and carbohydrates provide 4 calories per gram, whereas fats provide 9 calories per gram. Macronutrients provide the calories (energy) in our diet. Macronutrients are what we eat in large amounts, from the Greek word “makro” meaning large, they make up our diet as a whole and are defined as proteins, fats, and carbohydrates.

Do you think of carbs, protein, and fats, or do things like Keto, Paleo, or Atkins cross your mind? Do you think of zinc, iron, magnesium, or do you think of a big-box supplement store filled with various bottles and powders? Certain words have various meanings to different people so let’s start by defining some common terms and get started on the same page… In this randomized crossover trial, we observed nearly identical serum NEFA concentrations after each of 3 healthful diets, regardless of macronutrient content. In adjusted models, serum NEFA concentrations were positively associated, as anticipated, with female sex and higher BMI. Likewise, we observed no significant serum NEFA concentration difference by diet in adjusted GEE models. Comparisons of adjusted mean serum NEFA concentrations after each diet intervention identified no statistically significant differences (58% carbohydrate: 0.144 ± 0.083 mEq/L 25% protein: 0.143 ± 0.076 mEq/L 21% unsaturated fat: 0.143 ± 0.084 mEq/L ANCOVA, P = 0.99). Fifty-five percent of participants were women and 55% were African American. The mean ± SD age of study participants was 52.9 ± 10.6 y and mean BMI was 30.3 ± 6.1 kg/m 2. We used ANCOVA and generalized estimating equations (GEEs) to compare serum NEFA concentrations across the 3 diet periods. Data were analyzed from the 156 participants with unthawed serum available from the week 6 visit for all diet periods.

The trial included 164 participants who consumed the 3 diets, each for 6 wk. OMNI Heart compared 3 healthful diets to evaluate their effect on systolic blood pressure and serum LDL cholesterol: carbohydrate-rich diet (58% carbohydrate) protein-rich diet (25% protein), about half from plant sources and a diet rich in unsaturated fatty acids (21% unsaturated fat), predominantly monounsaturated. Total NEFAs were measured from postintervention specimens of participants in the OMNI Heart trial (Optimal Macronutrient Intake Trial to Prevent Heart Disease).

We sought to determine whether macronutrient content differences affect NEFA concentrations in a randomized crossover trial. Nonesterified fatty acids (NEFAs) play key roles in the pathophysiology of diabetes and cardiovascular disease.
