Definition of macronutrient in English:



  • 1A type of food (e.g. fat, protein, carbohydrate) required in large amounts in the diet.

    • ‘For example, because different macronutrients synergistically improve nutrition, consumers may choose foods that provide them with an appropriate balance of nutrients rather than an abundance of any single resource.’

    • ‘By eating the same amount of foods day after day, your body grows accustomed to the amount of fuel and macronutrients it's being supplied, and it begins to think of this as the status quo.’

    • ‘All of these macronutrients play vital roles in how your physique will continue to grow and develop over time.’
    • ‘Instead of eliminating a macronutrient (such as fat or carbohydrates) or a food group (such as fats and oils or breads), she should moderate her intake of each.’
    • ‘Keep in mind that one gram of fat contains nine calories, while the same amount of the other two macronutrients counts for four calories apiece.’
    • ‘Once the quota for macronutrients is met by consuming healthful quality foods, most bodybuilders still haven't fulfilled all their caloric needs.’
    • ‘Carbs are quite often the only macronutrients brought along for workouts in the wild; yet the argument underlying most of the protein plans is that starch is to blame for millions of bulging waistlines.’
    • ‘The bottom line is to make sure you're providing your body with adequate amounts of macronutrients at the appropriate times.’

    • ‘I'd like to see more of a Mediterranean-type approach with more balance among all macronutrients, concentrating more on the types of macronutrients rather than eliminating one or the other.’
    • ‘What's more critical in the comparison between cavemen and today's bodybuilders are the types of foods and ratio of macronutrients (protein, carbs and fat) consumed.’
    • ‘Most dietary guidelines emphasize target intakes of specific macronutrients.’
    • ‘To prevent illness and promote a healthy childhood, many parents turn to diet and nutrition since macronutrients, vitamins and minerals promote healthy minds and bodies.’
  • 2A chemical element (e.g. potassium, magnesium, calcium) required in large amounts for plant growth.

    • ‘Potassium, a macronutrient for plants, is present in plant dry matter next to carbon, hydrogen, oxygen, and nitrogen and before sulphur and phosphorus.’
    • ‘However, said Suping, a long-term solution would be to bio-augment the dam - a process that involves adding natural macronutrients to stimulate the emission of oxygen from natural organisms in the lake.’
    • ‘Sulfur is a macronutrient for both plants and animals.’
    • ‘The main characteristics of such soils are infertility due to the low level of macronutrients, a Ca: Mg ratio < 1, and the high concentration of heavy metals; moreover, these soils are shallow, well drained and prone to erosion.’
    • ‘We always think of plants as requiring the usual N-P-K macronutrients (nitrogen, phosphorus, and potassium), but we sometimes neglect to provide the many micronutrients roses and other plants need.’
    • ‘In addition to the macronutrients, plants also require smaller amounts of micronutrients to grow properly.’
    • ‘Phosphorus is one of three macronutrients needed by growing plants, the other two being nitrogen and potassium.’
    • ‘Lodhiyal et al. pointed out that the major macronutrients limiting the production of a forest crop are N, P and K.’
    • ‘The most abundant cationic component of plant cells is K +, a macronutrient that composes up to 10% of the total plant dry weight.’
    • ‘The supply of iron, relative to that of the macronutrients nitrate, phosphate, and silicic acid, plays a critical role in allowing extensive diatom blooms to develop in coastal upwelling regimes.’
    • ‘It indicates that there are measurable reductions in use of chemical fertilizers - most farmers use a combination of compost, animal manure or crop rotation to maintain fertility and replace macronutrients.’
    • ‘This could be particularly informative for biologists and geneticists who try to adapt plants to, for example, limited supplies of micro- and macronutrients or potentially toxic loads of ions.’
    • ‘Despite phosphorus being an important macronutrient required for plant growth and function, many soils throughout the world are deficient in forms of P that are readily available to plants.’
    • ‘It is one of the three macronutrients (in addition to nitrogen and phosphorus) required by plants.’
    • ‘The uptake of cadmium by plants is governed by a number of factors such as pH, temperature, aeration, total cadmium concentration in the soil and the presence of other micro- and macronutrients.’
    • ‘This factor may reflect essential plant macronutrients from materials leached from tree foliage and bark, or deposition of pollutants brought into the area by long-range transport.’
    • ‘It is chemically similar to sulphur, an essential plant macronutrient.’
    • ‘Soil samples were also evaluated for pH and other macronutrients by the Arkansas Soil Test Laboratory to ensure that any nutrient deficiencies could be appropriately amended.’
    • ‘Other macronutrients include potassium which helps maintain water balance and is involved in protein synthesis.’
