Vitamins called nutrition vitamins are vital compounds that work as cofactors in many metabolic reactions within the body. They are important to the immune system and normal growth and development. Vitamin deficiencies can lead to an array of health problems. As such, they have a large public health significance.
There are two types of vitamins: fat-soluble and water-soluble. The urine easily excretes water-soluble vitamins. The liver and tissues store fat-soluble vitamins. A deficiency of either vitamin can have serious consequences.
Vitamins can found in many different foods. Some vitamins can be found naturally, while others are synthesized by the body. Nearly all vitamins are essential for the functioning of our bodies. Therefore, it is important to eat a variety foods to meet your daily needs. Ask your doctor for guidance if you are unsure about your nutrient requirements. You may also want to consider taking a supplement.
The chemical properties and the ability of the molecule to dissolve in water, fat or other liquids determine the classification of vitamin. Vitamins can also have their function in the body classified according to how they are transported. Vitamin A, for example is absorbed via carrier-dependent mechanism at low concentrations.
It is becoming more important to pay attention to food-sourced vitamins. These studies have given insight into the metabolism of vitamins and the role of food in our health. Metabolic modifications of vitamins obtained from food can alter the structure or function of the vitamin. This can lead to structural changes, as well as to significant changes in the chemical properties of the vitamin.
Depending upon where a vitamin is found in the body's system, it can be classified as one of four groups: antioxidants enzymes hormones gene transcription elements and hormones. These four categories give a basis for understanding the importance of vitamins in human health. Additionally, vitamins are involved in the production of a variety metabolic enzymes and hormones. One of these is methyl malonyl mutase (CoA) coenzyme, which is necessary for mammalian cells metabolism.
Important connections have also been made between food-sourced vitamins and the bioavailability, or reversed epigenetic age. Vitamins are critical for the synthesis of neurotransmitters and steroid hormones, and for the formation of red blood cells. Vitamins are available in both plant- and animal-based diets.
Vitamins are also important for the protection of biological membranes from lipid peroxidation. Vitamin E, selenium, and other vitamins are involved in this process. Other vitamins can also be made endogenously by intestinal bacteria. Some vitamins are essential while others are optional. These vitamins can be found in small quantities from many sources.
At the moment, there is no one food that contains all the vitamins needed by humans. The recommended daily intake of vitamins will vary depending on the source of the vitamin and the gender. On average, a person needs 60 mg of vitamin A per day. Older adults need higher levels. Premenopause women also require higher iron requirements.
FAQ
What is the ideal weight for my height? BMI calculator and chart
Calculating your body mass index (BMI), is the best method to calculate how much weight to lose. Healthy BMI ranges between 18.5 to 24.9. If you want to lose weight, then you should aim to drop about 10 pounds per month. Simply enter your weight and height into the BMI calculator.
To see if you're overweight or obese, check out this BMI chart.
What is the difference between a virus and a bacterium?
A virus can be described as a microscopic organism incapable of reproducing outside its host cell. A bacterium can be described as a single-celled organism which reproduces by splitting in two. Viruses are small, around 20 nanometers in size. Bacteria are much larger, at 1 micron.
Viruses can be spread by contact with bodily fluids containing infected substances, such as saliva, urine and semen. Bacteria are often spread via direct contact with contaminated surfaces and objects.
Viral infections can be transmitted through skin cuts, scrapes and bites. They can also get into the skin through the nose, mouth and eyes, ears as well as through the rectum, rectum and anus.
Bacteria may enter our bodies through cuts and scrapes on our skin, burns, insect bites, and other wounds. They can also get into our bodies via food, water or soil.
Viruses and bacteria both cause illness. But viruses do not have the ability to multiply within their hosts. They can only infect living cells and cause illness.
Bacteria can multiply within their hosts and cause illness. They can spread to other parts of our bodies. To kill them, we must use antibiotics.
What's the difference between fat/sugar?
Fat is an important energy source, which comes from food. Sugar is a sweet substance found naturally in fruits and vegetables. Both fats (and sugars) have the exact same calories. However, fats contain more than twice as many calories as sugars.
Fats are stored in your body and can cause obesity. They can cause cholesterol buildup which can lead to strokes and heart attacks.
Sugars are quickly absorbed and provide instant energy. This causes blood glucose to rise. High blood glucose levels are dangerous as it can increase the likelihood of developing type 2 diabetes.
How do you know what is best for you?
Listen to your body. Your body knows what you need when it comes time to eat, exercise, and get enough rest. Your body will tell you what to do so that you don't go overboard. Pay attention to your body, and ensure that you're taking care of your health.
Is it possible to have a weak immune system due to being cold?
Being cold gives you a weaker immune system because when you are cold, your body produces less white blood cells which fight infections. Cold can also make you feel better as your brain releases endorphins, which reduce pain.

What does the term "vitamins" mean?
Vitamins can be described as organic compounds found in food. Vitamins aid us in absorbing nutrients from the food we eat. Vitamins cannot be made by the body; they must be taken from food.
Two types of vitamins exist: water soluble and oil soluble. Water-soluble vitamins dissolve quickly in water. Vitamin C,B1(thiamine), B2 (2riboflavin), and B3 (3niacin), as well as vitamin C,B1, B2 (riboflavin), and B3 (niacin), vitamin B6 (pyridoxine), vitamin folic acid (biotin), pantothenic, and choline are examples. Fat soluble vitamins are stored in the liver and fatty tissue. Examples include vitamin D, E, K, A, and beta carotene.
Vitamins are classified according their biological activity. There are eight major vitamin groups:
-
A - vital for normal growth and maintaining good health.
-
C – essential for proper nerve function.
-
D – Essential for healthy teeth, bones and joints
-
E - required for good vision & reproduction.
-
K - Essential for healthy muscles and nerves.
-
P - Vital for strong bones and teeth.
-
Q - aids in digestion of iron and iron absorption
-
R - Red blood cells are made from red blood cells.
The recommended daily allowance (RDA), for vitamins, varies based on gender, age, and physical condition. RDA values are set by the U.S. Food and Drug Administration (FDA).
For adults 19 years and over, the RDA vitamin A intake is 400mg/day. Pregnant mothers need 600 micrograms a day to ensure fetal growth. Children ages 1-8 require 900 micrograms per day. Infants below one year of age need 700 micrograms daily. But, between 9 months to 12 months of age, the amount drops to 500micrograms per days.
Children aged 1-18 years need 800 micrograms daily, while children overweight require 1000 micrograms per days. Children who are severely obese or underweight will need 1200 micrograms each day.
Children aged 4-8 who have anemia are required to consume 2200 micrograms of Vitamin C daily.
2000 micrograms per person is necessary for general health. Because of their higher nutrient needs, women who are pregnant or nursing need 3000 mg per day.
1500 micrograms is the recommended daily intake for adults aged 70+, as they lose 10% of their muscle every ten years.
Women who have been pregnant or are lactating require more than the RDA. Pregnant women require 4000 micrograms daily during pregnancy, and 2500 micrograms every day after birth. Breastfeeding mothers need 5000 mg per day when breastmilk is being produced.
