Lifestyle Activities

This term is frequently used to encompass activities that a person carries out in the course of daily life and that can contribute to sizeable energy expenditure. Examples include taking the stairs instead of using the elevator, walking to do errands instead of driving, getting off a bus one stop early, or parking farther away than usual to walk to a destination.

Lipid

A general classification to denote water-insoluble compounds, such as fatty acids and sterols.

Local Food Source

The average food item travels 1,550 to 2,480 miles across the United States to reach your dinner table, according to www.foodroutes.org By buying local, or closer to home, your food travels a shorter distance, which helps reduce global warming and air pollution and supports local farmers.

There is no specific definition, but many consumers say it should be produced within a 100-mile radius of their homes. The "Natural Resources Defense Council" helps you find the freshest, closest food now.

 

Locavore

A group of San Francisco women proposed only eating food grown or produced within a 100-mile radius of the city and called it 'locavore'. In 2007, it became the New Oxford American Dictionary word of the year, meaning a person who favors locally produced food over food produced in other regions.

 

Low Density Lipoprotein (LDL)

LDL is a compound made up of fat and protein that carries cholesterol in the blood from the liver to other parts of the body. High levels of LDL cholesterol, commonly called bad cholesterol, cause a buildup of cholesterol in the arteries and increase the risk of heart disease. An LDL level of less than 100 mg/dL is considered optimal, 100 to 129 mg/dL is considered near or above optimal, 130 to 159 mg/dL is considered borderline high, 160 to 189 mg/dL is considered high, and 190 mg/dL or greater is considered very high.

 

Lycopene

The prominent antioxidant in tomatoes, watermelon, and pink grapefruit also gives these foods their color and may fight cancer by preventing free radicals from binding with oxygen. Its other health benefits may include protecting against age related macular degeneration, reducing the risk of lung damage, and thinning the blood of people with type 2 diabetes to help decrease the chance of clots and associated heart troubles.

 

Lysine

See Essential Amino Acids.

 

Macronutrient

A dietary component that provides energy. Macronutrients include protein, fats, carbohydrates, and alcohol.

Magnesium

Magnesium is an essential mineral for the human body. It is needed for protein, bone, and fatty acid formation, making new cells, activating B vitamins, relaxing muscles, blood clotting, and forming adenosine triphosphate (ATP). The production and use of insulin also requires magnesium. Under certain circumstances magnesium has been found to improve vision in people with glaucoma. Similarly, magnesium has demonstrated an ability to lower blood pressure.

Manganese works with vitamin K to support normal blood clotting. Working with the B-complex vitamins, manganese helps promote a positive outlook when faced with stress, frustration, and anxiety.

Maltitol

See Sugar Alcohol.

 

Manganese

Manganese is an essential trace mineral that is required in small amounts to manufacture enzymes necessary for the metabolism of proteins and fat. It also supports the immune system and blood-sugar balance and is involved in the production of cellular energy, reproduction, and bone growth.

Mannitol

See Sugar Alcohol.
