Macro-nutrients

The body needs protein (complete) carbohydrates, and fats (yes fats) to repair, supply energy, and maintain good health. As a bodybuilder these basic macro-nutrients and micro-nutrient containing foods are the raw materials utilized to build and shape your living work of art. Buy and learn to use a nutritional almanac. 

Ratios of Macro-nutrients are also paramount to create an environment for the best athletic and /or aesthetic results. For most non-obese clients I advise a general Macro-nutrient calorie distribution/ratio of 30-40% protein, 40-50% carbohydrates,... 

Antioxidant-rich phytochemicals are micro-constituents in plants and agricultural food products. They differ from proteins, carbohydrates, and lipids, which are macro-nutrients that are abundant in plants and food products. The type and quantity of antioxidant-rich phytochemicals vary significantly from source to source. Different types of the antioxidant-rich phytochemicals may have different antioxidant and other biological activities and bio availability. Although most phytochemicals have UV absorption, using traditional spectrophotometeric methods to quantify the antioxidants is not practical as they could be significantly masked or interfered with by many other compounds in the sources. Thus, the analysis methods for antioxidant-rich phytochemicals are more complicated and sophisticated than the methods used for macro-nutrient compounds. 

The health benefits of food and food constituents is currently gaining much attention. New biotechnological techniques allow the enrichment of food with micro- and macro-nutrients such as rice with high levels of vitamin A, tomatoes with extra flavonoids and also milk with additional calcium. These frmctional foods are often coimected with health benefits. Specific food constituents in a pharmaceutical formulation are called nutraceuticals. These are frequently associated with medical claims.

Of particular interest in relation to Si N interactions and diatoms is the relatively recent finding that iron provides a strong regulating influence on the species composition of phytoplankton assemblages, as well as on the elemental ratios of diatoms. Fe and Si supply appear to be particularly important in several large areas where high concentrations of other macro nutrients (N, P) are present in surface waters. These HNLC areas (Minas et al, 1986) are characterized by low phytoplankton biomass...

The second characteristic feature of Forest Ecosystem soils is the accumulation of macro-nutrients in the litter with sharp decreasing to the download horizon. However, the trace elements show the opposite trend and the concentration of micro-nutrients is gradually increasing up to the soil forming rocks.

This chapter will provide an overview of the factors which have been studied most extensively as potential inhibitors of cancer. It will stress data in the areas where recommendations have been made to the public (1,2). We will begin with a discussion of the macro-nutrients which have received the greatest attention for their potential for modifying cancer risk, dietary fat and fiber, and the relation of these nutrients to calorie Intake. 1 will then describe data suggesting that mlcronutrlents such as vitamins A, C, and E, and the trace element selenium, may have some potential in the inhibition of cancer. Finally, I will present some recent data in support of cancer prevention by some non-nutrient components of fruits and vegetables.

The calculation of the energy, substrate and volume needs in parenteral nutrition is given in textbooks and guidelines [52]. The needs depend on the patient s disease and nutritional status. The first step is the specificatirMi and calculation of the necessary amounts of fluid, glucose, and amino acids (macro-nutrients). The second step includes the calculation of the electrolytes. Vitamins and trace elements are commonly added in standard amounts according to professional guidelines. 

There are about forty elements involved in the life processes of living oig anisms out of which about thirty elements are essential for healthy human beings. These are Na, K, Mg, Ca, V, Cr, Mo, Mn, Fe, Co, Cu, Zn, Sn (metals) and H, C, Si, N, P, O, S, Se, F, Cl, Br, I (non metals). The elements H, C, N, O are taken in the form of proteins, c irbohydrates and lipids. These are the major constituents of cur food. Besides these, some elements are needed more than 1 mg in our food. These are Na, K, Mg, Ca, P, S and Cl. They are called macro nutrients or princ al elements. They constitute 60-80% of body s inoiganic elements. 

What are macro nutrients Discuss in detail the role played by sodium, potassium and chlorine. 

Of the various elements that are ktiown to be essential for the proper growth and reproduction of plants, Nitrogen, Phosphorus and Potassium are required in relatively large amounts and so are known as major elements or macro-nutrients. A deficiency of one or more of these elements in soil may limit the growth of a particular plant or crop and may thus decrease soil fertility.
