The digestive system
A macronutrient is a type of nutrient in any food which is required in large quantities in a
person's diet. Examples of macronutrients are sugar, carbohydrates and proteins, which
each have different roles. A micronutrient is an essential element required in smaller
amounts. Examples of these are minerals and vitamins; e.g zinc, potassium, iron,
copper and cobalt. Zinc comes from beef, cashews, garbanzo beans, and turkey.
Vitamins are necessary for energy production, immune function, blood clotting and other
functions. Meanwhile, minerals play an important role in growth, bone health, fluid
balance and several other processes. Micronutrients work in tandem with
macronutrients to keep the body functioning and are crucial in order to maintain energy
levels, metabolism, cellular function, and physical and mental wellbeing.
In a roast dinner, some macronutrients may be present like fats, sugars, proteins and
carbohydrates. Some micronutrients that may be present in the roast dinner are
calcium, vitamins, copper, iron, magnesium, phosphorus, thiamine and zinc. The role is
maintaining health and helps absorb vitamins A, vitamins D and vitamin E. These
vitamins are fat-soluble, meaning they can be absorbed only by the help of fats. Any fat
not absorbed not used by body cells or in the production of energy is converted into
body fat. Fats are an essential part of a healthy diet and should account for about
15-20% what you consume. They help by improving brain development, overall cell
functioning, protecting the body’s organs and even helping you absorb vitamins found in
foods. The role of carbohydrates in keeping health and function of the body is to provide
the body with energy in the form of ATP. This is made in many processes, for example
respiration. Four functions of carbohydrates in the body are to provide energy, store
energy, build macromolecules, and spare protein and fat for other uses. Glucose energy
is stored as glycogen, with the majority of it in the muscle and liver. This makes up
around 45-65% of a diet. Examples of carbohydrates are apples, bananas, cauliflower,
carrots, oats, brown rice, millet, quinoa, chickpeas, kidney beans. The role of sugars in
stabilizing health and function of the body and providing energy. During digestion,
sugars are broken down both mechanically and chemically,by enzymes, into the single
units glucose, fructose, and galactose, which are absorbed into the bloodstream and
transported for use as energy throughout the body. During pregnancy, glucose helps
make milk. The digestion of protein enables breaking the complex molecule first into
peptides, each having a number of amino acids, and second into individual amino acids.
The pepsins are enzymes secreted by the stomach in the presence of acid that breaks
down proteins. Proteins are used for growth and repair of muscle fibres and bones and
can be seen as an essential building block.. Proteins are also used to make enzymes,
hormones and other chemicals in the body.

A roast dinner is made of meat,
potatoes, yorkshire pudding, and
vegetables. Meat is an example protein
which is a macronutrient that is
essential to building muscle mass. It
aids in muscle and bone growth and
repair. Potatoes are an example of
carbohydrates which are also
macronutrients which is an essential in
providing energy to the body's process.
Yorkshire pudding is a common English
side dish consisting of a baked pudding
made from batter consisting of eggs,
flour, and milk or water. Vegetables are
an important part of healthy eating and
provide a source of many nutrients,
including potassium, fiber, folate and
vitamins A, E and C. Options like
broccoli, spinach, tomatoes and garlic
provide additional benefits, making
them a superfood.
The small intestine's main job is to absorb nutrients from the food taken in to the body
and the villi help by increasing the surface area that the intestine has for absorption.
Intestinal villi are small, finger-like projections that extend into the lumen of the small
intestine.The large intestine also performs the functions of absorption, but without villi
because the large intestine is wider and shorter than the small intestine and has a
smooth inner wall. They contain specialized cells that transport substances into the
bloodstream. Although these villi do not aid in the digestion of nutrients, they do help
with nutrient absorption. The villi also contain vessels called lacteals.
