Summary
Folate is crucial for health, preventing neural tube defects and potentially stroke. A specific MTHFR gene variant increases cardiovascular risk, but riboflavin supplementation may mitigate this by lowering blood pressure.
Area of Science:
- Nutritional biochemistry
- Genetics
- Public health
Background:
- Folate is essential for one-carbon metabolism, impacting homocysteine levels.
- Elevated homocysteine indicates functional folate deficiency.
- Folate status is vital for preventing neural tube defects and stroke.
Purpose of the Study:
- To review the lifecycle roles of folate.
- To discuss public health strategies for optimizing folate status.
- To explore emerging roles and genetic interactions of folate metabolism.
Main Methods:
- Literature review of scientific evidence on folate's roles.
- Analysis of genetic determinants of homocysteine, specifically the MTHFR 677C→T polymorphism.
- Examination of studies on folate interactions with other nutrients, like riboflavin.
Main Results:
- The MTHFR 677TT genotype is linked to reduced enzyme activity, elevated homocysteine, and increased cardiovascular disease (CVD) risk.
- A novel interaction between the MTHFR polymorphism and riboflavin was identified.
- Riboflavin supplementation in TT genotype individuals lowered blood pressure in hypertensive and CVD patients.
Conclusions:
- Folate plays critical roles in health across the lifespan.
- Genetic variations in folate metabolism influence health risks, particularly CVD.
- Targeted nutrient interventions, like riboflavin for MTHFR 677TT individuals, show promise for cardiovascular health.

01:28Proteins: Dietary Sources and Requirements
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...
01:18Lipids: Dietary Sources and Requirements
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...
01:30Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
01:25Role of Vitamins in Maintaining Bone Health
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

01:15Carbohydrates: Dietary Sources and Requirements
Carbohydrates are predominantly obtained from plant sources. With the exception of lactose found in milk and insignificant glycogen amounts in meat, most consumed carbohydrates have plant origins. Monosaccharides and disaccharides, or sugars, can be sourced from fruits, honey, milk, sugar cane, and sugar beets. Grains and vegetables are rich in the polysaccharide starch. Two types of polysaccharides provide fiber: cellulose, which is abundant in many vegetables, forms undigestible roughage or...
01:27Parentral Nutrition: Centeral and Peripheral Parental Nutrition
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
