Fat is created in the body through a process called lipogenesis, which involves converting excess energy from food (calories) into fat and storing it for future energy needs. This process is tightly regulated by hormones and occurs in specialized fat-storing cells called adipocytes. Here’s a breakdown of how fat is created: 1. Sources of Fat […]

Anemia is a medical condition characterized by a lower-than-normal number of red blood cells (RBCs) or a deficiency in hemoglobin, the protein in RBCs responsible for carrying oxygen throughout the body. This condition results in a reduced ability of the blood to deliver oxygen to tissues and organs, leading to various symptoms and complications. Common […]

Being anemic can have serious negative consequences because it reduces the amount of oxygen your blood can deliver to your body’s tissues and organs.

Anemic people often feel colder than others because their bodies struggle to generate and maintain sufficient heat due to reduced oxygen delivery and blood flow. Here’s why anemia can make someone feel cold: 1. Reduced Oxygen Delivery Hemoglobin in red blood cells carries oxygen to tissues. When a person is anemic, there’s less hemoglobin, so […]

Iron is an essential mineral that can be obtained from a variety of dietary sources. There are two main types of iron found in food: heme iron and non-heme iron. Heme Iron (Most Readily Absorbed) Heme iron is found in animal-based foods and is more efficiently absorbed by the body. The following are significant sources: […]

Hematocrit is a measure of the proportion of red blood cells (RBCs) in your blood. It is expressed as a percentage and represents the volume of red blood cells compared to the total blood volume, which includes plasma (the liquid part of blood) and other cells. For example: A hematocrit of 40% means that 40% […]

A1c, also known as hemoglobin A1c or glycated hemoglobin, is a blood test that measures the average blood sugar (glucose) levels over the past 2 to 3 months. It reflects the percentage of hemoglobin (a protein in red blood cells that carries oxygen) that is coated with sugar (glycated). Why Is A1c Important? The A1c […]
