FOOD CHEMISTRY
-
-Fat are nutrients in food that the body uses to build nerve tissues including the brain and nerves and hormones
- the energy produced by fats is 9 calories per gram
- fat gives food flavor and texture but it’s also high in calories and excess amounts of fatty foods can cause many health problems
-
Fats also known as triglycerides, molecules made from the combination of one molecule of glycerol with three fatty acid
Fats can be classified as either saturated or unsaturated depending on the structure of the long carbon-carbon chains in the fatty acids
-
Unsaturated fats contain some number of double bonds in their structure. These fats are generally liquid at room temperature (fats that are liquid at room temperature are referred to as oils). Unsaturated fats can be either polyunsaturated (many double bonds) or monounsaturated fats (one or few double bonds)

( exp: olives, peanut butter and nuts)

-Food contains saturated fat contributes to your gaining weight since it will heap in every part of our body tissue.
-
-The development of cancer cells in our body is triggered by bad eating pattern: too much consuming food contains fat and less fibers.
-
-
Unlike saturated fats, found in animal products and fried foods, healthy fats promote positive cardiovascular health. Omega-3 fatty acids, for example, provide protection from hypertension, cholesterol problems and heart disease
-
Because fats help your body absorb and utilize the fat-soluble vitamins A, D, E and K, consuming too little fat makes way for vitamin deficiencies.
-
-
-
Fats help the brain produce feel-good brain chemicals, such as serotonin and dopamine. They also increase your ability to concentrate, staving off foggy thinking and low moods

CARBOHYDRATE
Carbohydrate is the important macronutrient in the body. Carbohydrate consist from element carbon, hydrogen and oxygen which is the ratio is 1:2:1. it is the main component that contribute energy to build a healthy body
