The essential components of our food are called __________ .
The components of food are certain organic substances and minerals found in food. They are called nutrients. Nutrients provide the body with energy and enable it to grow, repair and maintain itself. Hence it is important that we understand the exact role of nutrients in our food and recognize the various foods that provide these nutrients.
Which of the following nutrients is not present in milk?
Milk contains almost all vitamins, but vitamin such as niacin, vitamin C, vitamin E and K are present in very less amount. So milk is not considered a major source of the mentioned vitamins in the diet.
The food component present in sugar is
The kind of sugar we usually think about - table sugar - is called sucrose. Sugar is made up of carbon, hydrogen and oxygen atoms. It's the way these atoms are connected that makes each type of carbohydrate different. In each molecule of table sugar there are: 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.
What fraction of your body is water?
About 2/3 of the average human body is water, mostly within the cells. The amount of water in the human body ranges from 50-75%. The average adult human body is 50-65% water, averaging around 57-60%. The percentage of water in infants is much higher, typically around 75-78% water, dropping to 65% by one year of age. Thus, option B is correct.
Foods like pizza, burger and noodles are rich in
Burgers and pizzas from big fast food chains are called junk food because they usually have a lot of calories and are very high in fat, carbs, sodium and/or sugar, while having little nutritional value.
_________ provide more than double the energy provided by carbohydrates or proteins in human body.
Fat produces more than two times energy per gram than either carbohydrates or protein. Metabolism in the body converts carbohydrates, protein and fat into energy. Any excess of these nutrients will be stored as fat in the body. In other words, regardless of whether it is carbohydrates, protein or fat, it will be converted into fat storage in the body if it is not used. As our body fat accumulates, our body weight increases.The calories in food come from carbohydrates, proteins, and fats. A gram of carbohydrate contains 4 calories. A gram of protein also contains 4 calories. A gram of fat, though, contains 9 calories — more than twice the amount of the other two.
The component of food which help our body to fight against infections is
Proteins help form immunoglobulins, or antibodies, to fight infection.
Antibodies are proteins in your blood that help protect your body from harmful invaders like bacteria and viruses.
Our body prepares which type of Vitamin in the presence of sunlight?
Vitamin D3 (cholecalciferol) is synthesized in the skin by the reaction of 7-dehydrocholesterol with UVB radiation, present in sunlight with an UV index of three or more.
The disease caused by the deficiency of iron is
Iron deficiency anemia is a common type of anemia — a condition in which blood lacks adequate healthy red blood cells. Red blood cells carry oxygen to the body's tissues.
The mineral which controls the functioning of thyroid is
The mineral selenium helps your thyroid produce thyroid hormone, convert T4 into T3, and can lower thyroid peroxidase antibodies. Selenium deficiency is also linked to worsening of thyroid eye disease and an increased risk of postpartum thyroid problems.
The disease caused by the deficiency of iodine is
Iodine deficiency is the major cause of goiter worldwide, but this is rarely a cause in more economically developed countries where iodine is routinely added to salt.
As iodine is less commonly found in plants, vegan diets may lack sufficient iodine. This is less of a problem for vegans who live in countries such as the United States that add iodine to salt.
Dietary iodine is found in:
2. Plant food grown in iodine-rich soil
3. Cow's milk
________ helps to maintain a constant body temperature in our body.
Because water can absorb and transfer heat well, the human body uses it to stabilize temperature. Water also helps expel excess heat from the body as water vapor from the lungs and sweat on the skin.
Your body needs ____ litres of water every day.
Health authorities commonly recommend eight 8-ounce glasses, which equals about 2 litres, or half a gallon.
The indigestible material present in food is known as
Roughage is the rich fibrous indigestible edible material present in our food in form of grains or vegetables, which helps in elimination of waste from large intestine.
Rickets is caused by the deficiency of
Rickets is a bone disorder caused by a deficiency of vitamin D, calcium, or phosphate. There are different bony abnormalities associated with rickets, but all are due to poor mineralization with calcium and phosphate. The active form of vitamin D is synthesized by skin cells when exposed to sunlight.
Excessive body weight due overnutrition leads to
Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. Overweight and obesity are major risk factors for a number of chronic diseases, including diabetes, cardiovascular diseases and cancer. Once considered a problem only in high income countries, overweight and obesity are now dramatically on the rise in low- and middle-income countries, particularly in urban settings.
Vitamins and minerals are
Protective foods are the foods that contain adequate amounts of vitamins, minerals, and high-quality proteins and they protect against the development of a deficiency disease. Including protective foods in your diet is a natural way to fight disease, ward off infection and maybe even extend your lifespan. Protective foods have benefits beyond disease prevention as well. The calcium and nutrients found in low-fat dairy products, vegetables, fruits, grains and lean proteins, for example, can guard against certain cancers, hypertension, scurvy, diabetes, osteoporosis heart disease, bone loss, kidney stones and stroke. Diet alone cannot guarantee good health and is not a magical cure-all, but its significance is enormous.
Jaggery is a good source of
Jaggery contains about 98% carbohydrates and about 97% sugar content. 10 grams jaggery provides 38 calories. It is Indian sweetener manufactured from sugarcane. It might be a healthy substitute of industrial sugar or chemically processed and cleaned sugar.
The highest concentration of minerals are found in
Of this 90% is accounted for by seven minerals (calcium, phosphorus, potassium, sulphur, sodium, chloride and magnesium). The other minerals are known as trace elements as these add together to about 10% of the total mineral content of the body. The largest concentration of minerals is found in the bones and teeth.
Iodine is used to test the presence of ________ in the food.
Iodine can be used in a simple test for starch. Iodine is normally a brownish-yellow color. However, in the presence of starch, iodine turns blue or bluish-black in color.
Which of the following is a protective food?
Foods that contain large amount of antioxidants that make free radicals harmless are called protective foods. Foods rich in vitamins and minerals are referred to as protective foods as they provide immunity and protect our body from various diseases and infections. All fruits and vegetables as well as dairy products are examples of protective foods.
The mineral we get from fish is
Vitamin A is needed for healthy vision as well as for healthy skin, while vitamin D is essential in bone development. Fish is rich in calcium and phosphorus and a great source of minerals, such as iron, zinc, iodine, magnesium, and potassium.
Scurvy (Bleeding gums) is caused due to the deficiency of
Scurvy is the name for a vitamin C deficiency. It can lead to anemia, debility, exhaustion, spontaneous bleeding, pain in the limbs, and especially the legs, swelling in some parts of the body, and sometimes ulceration of the gums and loss of teeth.
Night blindness is caused by the deficiency of
Night blindness caused by nearsightedness, cataracts, or vitamin A deficiency is treatable. Corrective lenses, such as eyeglasses or contacts, can improve nearsighted vision both during the day and at night. Let your doctor know if you still have trouble seeing in dim light even with corrective lenses.
Benedict's solution is used to test the presence of _____ in food.
Benedict's solution is used to test for simple sugars, such as glucose. It is a clear blue solution of sodium and copper salts.
