GENETICALLY MODIFIED ORGANISM (GMOs)

What is genetically modified organism?

A genetically modified organism (GMO) is an animal, plant, or microbe whose DNA has been altered using genetic engineering techniques.


How do we make GMOs?



  1. Identify: Scientists identify what trait they want a plant to have. Then, they find an organism that already has that trait within its genes.
  2. Copy: Aster scientists find the gene with the desired trait, they copy that gene.
  3. Insert: Next, scientists use tools to insert the gene into the DNA of the plant.
  4. Grow: In the laboratory, scientists grow the new plant to ensure it has adopted the desired trait. If successful, scientists then grow and monitor the new plant in greenhouses.

Why do we use GMOs?

  • Increased crop yields
  • Reduced costs for food production
  • Reduced need for pesticides
  • Enhanced nutrient composition and food quality
  • Resistance to pests and disease
  • Greater food security
  • Medical benefits to the world's growing population

WORLD HUNGER

   What is "World Hunger" ?     The United Nations’ (UN) Hunger report defines hunger as “ periods when populations are experiencing severe food insecurity .” World hunger is when people spend entire days with nothing to eat due to various reasons such as lack of money and lack of access to food and other resources. When a person consumes below 1,800 calories per day , it qualifies as food deprivation or undernourishment. What are the causes of "World Hunger" ? Climate change and natural disasters Conflict in several territories The socio-economic effects of the COVID-19 pandemic Why is "World Hunger" is a problem? The effects of world hunger are as diverse as they are devastating. At its core, a diet characterized by an  insufficient intake of calories, proteins, vitamins and minerals impedes human development   at every level. For example, infants, children and adults. In turn, this negatively impacts the health, education, economic and social developm...

FUNCTIONAL FOOD, NUTRACEUTICALS AND DIETARY SUPPLEMENTS

  FUNCTIONAL FOOD Nutrient consumed as a part of a normal diet but delivering one or more active ingredients (that have physiological effects and may enhance health) within the food matrix. The functional food category and examples are shown as below : HOW ARE FOODS MADE TO BE "FUNCTIONAL"? 1) Taking out potentially harmful components. For example, cholesterol in egg yolk and lactose in milk. 2) Increasing the amount of nutrients and beneficial non-nutrients. For example, fiber-fortified liquid meals, calcium-, and vitamin C-fortified orange juice. 3) Using beneficial substances in food production or products. For example, using bacteria in fermented milk and soy products. DIETARY SUPPLEMENTS A product (other than tobacco) that is intended to supplement the diet , which contains one or more of the following dietary ingredients. A vitamin, a mineral, an herb or other botanical, an amino acid, a dietary substance to supplement the diet by increasing the total daily intake, or ...

GLYCEMIC INDEX

  WHAT IS GLYCEMIC INDEX (GI)? The glycaemic index (GI) is a rating system for foods containing carbohydrates . It shows how quickly each food affects your blood sugar (glucose) level when that food is eaten on its own . Foods are classified as low, medium, or high glycemic foods and ranked on a scale of 0–100. The lower the GI of a specific food, the less it may affect your blood sugar levels. Here are the three GI ratings:             - Low : 55 or less            - Medium : 56 - 69            - High : 70 or above HIGH GI FOOD Carbohydrate foods that are broken down quickly by your body and cause a rapid increase in blood glucose have a high GI rating. Some high GI foods are  : LOW AND MEDIUM GI FOOD Low or medium GI foods are broken down more slowly and cause a gradual rise in blood sugar levels over time . Some examples are : Some fruits and vegetables Pulses Wholegrain...
