There are three types of body fat

Skinfold self-testing at home
There are three types of body fat: The first is subcutaneous fat, which is stored
right below your skin. Second, there's intramuscular fat, which is inside the muscle
tissue (picture the fat inside a "marbled steak."). Third, you have internal fat,
which is located on and around your internal organs for protective cushioning.
Skinfold testing is based on the premise that the majority of your body fat is
subcutaneous– right below your skin where you can see and grab it. By "pinching"
the skin and fat and measuring the thickness of the fold at one or more sites, you
can get a fairly accurate estimate of your total body fat percentage...and more
importantly, a way to consistently measure your progress from week to week.
Until quite recently, a challenge many people faced was not having an experienced
fitness professional available to test you. For years, a skinfold test could only be
performed by somebody else (there was no way to "pinch yourself.") A second
person was required to "pinch your fat" at several locations, including spots you
can't reach, such as your upper back. Even if you were the "human pretzel" and
you could somehow reach around and measure all your own skinfolds, it wouldn't
be accurate.
This problem was surmounted when a company called Accu-Fitness invented an
inexpensive plastic skinfold caliper called the Accu Measure. The Accu Measure is
different from other calipers because it was designed so you can measure your
own body fat at home and you don't even need another person to help! This
method is inexpensive, convenient and private!
There's a LOT to be said for the accountability factor when you have a coach or
trainer measure your body fat every week. However, the privacy factor of the Accu
Measure is also nice because if you're like most people, you prefer not to have a
stranger groping your fat rolls every week. It's kind of embarrassing in the
beginning... although once you start getting leaner, you may surprise yourself
when one day you're proud to have someone "pinch you" - because there's nothing
there but thin skin on top of rock hard muscle!)

Is β-Carotene and Other Carotenoids Important in Cancer Prevention?

Is β-Carotene and Other Carotenoids Important in
Cancer Prevention?
β-Carotene and other carotenoids has long been speculated as reducing
the risk of cancer. In accordance, several studies of populations have
suggested that when people ate more carotenoids the presence of cancer
was lower. Interestingly, while β-carotene often receives the most atten-
tion other carotenoids have been shown to strong benefit as well. For
example, studies involving smokers have suggested that the dietary intake
of total carotenoids, lycopene, β-cryptoxanthin, lutein, and zeaxanthin
have a more clear relationship to reducing lung cancer risk. Thus it makes
sense to eat a diet rich in fruits and vegetables to allow for a broad variety
of carotenoids and to plan a supplementation regimen along this line of
thinking as well.

The environment that we inhabit

    The Very Basics of Humans
   All that we (our body) are, ever were, or are going to be is borrowed
from the environment that we inhabit. This unique state of indebtedness
is primarily attributed to our nutrition intake. We must be grateful to the
earth's crust for lending us minerals that strengthen our bones and teeth
and allow us to have electrical operations that drives nerve and muscle
function. We must also pay homage to plants for the carbohydrate forms
that power our operations and for the amino acids that make the protein
in our muscle.
    Nutrition refers to the science of nourishing our body.
   All too often we do not truly appreciate the relevance of nutrition to
our basic being. But again, please keep in mind that nearly everything we
are and are able to do is either a direct or indirect reflection of our past
and current nutrition intake. No matter how oversimplified nutrition
may seem in television commercials and on cereal boxes, it is without a
doubt one of the most complex and interesting sciences out there. One of
the major tasks of this site is to provide an understandable overview of
nutrition as it applies to optimal health and longevity.
