Abstract
This paper reviews and discusses the health benefits of eating foods containing docosahexaenoic acid (DHA). The paper reports that research has proven DHA to not only be essential for the functional development and growth of an infant's brain, but that it is also vital for the preservation of an adult's normal brain functioning. According to the paper, sources of DHA include fatty fish such as tuna, salmon and mackerel.

From the Paper
"Associated risks for eating fish include potential effects of extremely high methylmercury intake, however, chronic exposure to low levels are not solidly grounded regarding health effects. Women of childbearing age, according to the Environmental Protection Agency, need to avoid eating shark, swordfish, King mackerel and golden bass and only eat up to 12 ounces per week of other fish and shellfish. It is recommended that women of childbearing age do not eat more than 6 ounces of Albacore tuna each week."
"In practice, fish consumption, particular oily fish and shellfish, reduces CHD mortality and is noted to likely improved neurological functioning. Potential risks from dioxin, mercury and PCB contamination are outweighed by DHA's probable benefits."

Abstract
The paper describes the development of the embryo in the first three months, known as the first trimester. The paper discusses a new test that can detect Down syndrome earlier through the use of a blood test and an ultrasound examination, and then looks at the role of fatty acid DHA in the central nervous system and the need for caution in Vitamin A supplementation. The paper also examines the impact of stress on the embryo and relates that severe stress in the first trimester may prompt early delivery.

Outline:
A New Test for Down Syndrome
Maternal Diet Significant in the First Trimester
Caution Over Vitamin A Supplements
Stress in the First Trimester

From the Paper
"A new life begins when a woman's ovum or egg unites with a man's sperm in a process called fertilization (Bennington, 2001). That new life develops in the woman's body during pregnancy, which usually takes nine calendar months. Pregnancy is also called the gestation period. The gestation period, in turn, consists of three trimesters. These trimesters consist of the different stages of the embryo or fetus' development. The first trimester covers the first 13 weeks of pregnancy or the first 12 weeks of life. The second trimester covers the 14th to the 26th weeks and the third trimester, the 27th to the 40th weeks (Bennington)."
