Recommended Intake (RI) and Deficiency are terms used in
nutrition to describe the amount of a nutrient that is considered to be
adequate for most healthy people. The RI is based on scientific evidence of the
amount of a nutrient that is needed to prevent deficiency symptoms and promote
optimal health. A deficiency occurs when the body does not get enough of a
nutrient. This can lead to a diversity of health problems, depending on the
nutrient.
The RI is different for each nutrient and is based on
factors such as age, sex, and pregnancy status. For example, the RI for vitamin
C is 90 milligrams (mg) for adults aged 19 and older. This means that most
healthy adults need to eat at least 90 mg of vitamin C per day to prevent
deficiency symptoms.
A deficiency occurs when the body does not get enough of a
nutrient. This can happen for a diversity of reasons, including:
Not eating enough foods that contain the nutrient.
Having a condition that affects nutrient absorption.
Taking certain medications that can interfere with nutrient
absorption.
The symptoms of a nutrient lack can vary depending on the
nutrient. Some common symptoms of nutrient deficiencies include:
Fatigue
Weakness
Hair loss
Brittle nails
Dry skin
Constipation
Diarrhea
Anemia
Numbness or tingling in the hands and feet
Vision problems
Cognitive decline
If you think you may have a nutrient deficiency, it is
important to see a doctor or registered dietitian. They can help you determine
if you have a deficiency and recommend ways to increase your intake of the
nutrient.
Here are some tips for getting the recommended intake of
nutrients:
Eat a diversity of healthy foods from all food groups.
Choose foods that are obviously rich in nutrients.
Limit processed foods and sugary drinks.
Take a daily multivitamin and mineral supplement if you are
not sure if you are getting enough nutrients from your diet.
It is important to note that the RI is just a general
guideline. Some people may need more or less of a certain nutrient depending on
their individual circumstances. If you have any concerns about your nutrient
intake, talk to your doctor or registered dietitian.
What is recommended energy and nutrient intake? And, More
The recommended energy and nutrient intake varies depending
on a number of factors, including age, sex, activity level, and health status.
The Dietary Reference Intakes (DRIs) a set of nutrient intake guidelines for
Americans and Canadians. The DRIs are based on scientific evidence and are
designed to meet the needs of most healthy people.
The DRIs include the following:
Recommended Dietary Allowances (RDAs): The RDA is the
average daily consumption level that is sufficient to meet the nutrient supplies
of nearly all (97–98%) healthy persons in a particular life stage and sex
group.
Adequate Intakes (AIs): The AI is the average daily consumption
level that is assumed to be adequate for individuals in a particular life stage
and sex group. The AI is used when there is not enough scientific evidence to
develop an RDA.
Tolerable Upper Intake Levels (ULs): The UL is the uppermost
level of daily nutrient consumption that is likely to be safe for most
individuals. Exceeding the UL may increase the risk of adverse health effects.
It is important to note that these are just general
guidelines. Individual needs may vary depending on a number of factors. If you
are concerned about your energy or nutrient intake, talk to your doctor or
registered dietitian.
Why is recommended intake important?
Recommended intake is important because it helps safeguard
that you are getting the nutrients your body needs to function properly. When
you do not get enough of a nutrient, you may experience deficiency symptoms.
These symptoms can vary depending on the nutrient, but they can include
fatigue, weakness, hair loss, brittle nails, dry skin, constipation, diarrhea,
anemia, numbness or tingling in the hands and feet, vision problems, and cognitive
decline.
Recommended intake also helps prevent chronic diseases. Many
chronic illnesses, such as heart illness, stroke, category 2 diabetes, & some
kinds of cancer, are linked to poor diet. Getting the recommended intake of
nutrients can help reduce your risk of developing these diseases.
There are a few things you can do to make sure you are
getting the recommended intake of nutrients:
Eat a diversity of healthy foods from all food groups.
Choose foods that are obviously rich in nutrients.
Limit processed foods and sugary drinks.
Take a daily multivitamin and mineral supplement if you are
not sure if you are getting enough nutrients from your diet.
It is important to talk to your doctor or registered
dietitian if you are worried about your nutrient intake. They can help you
create a personalized plan to meet your individual needs.
