Question

Accepted Answer

### 1. Describe one of the earliest recorded food regulations.
# Brief Explanations:
One of the earliest food regulations was in ancient Rome, where laws were set to prevent adulteration of wine and bread. For example, bakers were regulated to ensure fair weights and quality of bread, and wine merchants were restricted from adding harmful substances to wine. In the Middle Ages, guilds also regulated food production (like butchers’ guilds ensuring meat quality). Another early example is from ancient Egypt, where there were standards for grain trading to prevent fraud.
# Answer:
One early food regulation was in ancient Rome, where laws regulated bakers (ensuring fair bread weights/quality) and wine merchants (preventing adulteration with harmful substances). Or, in ancient Egypt, grain trading had standards to avoid fraud.

### 2. Which two federal agencies did President Lincoln introduce?
# Brief Explanations:
President Lincoln established the United States Department of Agriculture (USDA) in 1862 to support farming/agriculture, and also the Internal Revenue Service (IRS) (via the Revenue Act of 1862) to collect income taxes to fund the Civil War.
# Answer:
President Lincoln introduced the **United States Department of Agriculture (USDA)** (1862, to support agriculture) and the **Internal Revenue Service (IRS)** (via the 1862 Revenue Act, to collect income taxes for the Civil War).

### 3. What does the NLEA stand for? When was it passed, and how does it affect consumers?
# Brief Explanations:
NLEA stands for the Nutrition Labeling and Education Act. It was passed in 1990. It requires food manufacturers to include nutrition labels (with info like calories, fat, nutrients) on packaged foods, and regulates health claims on labels. This helps consumers make informed choices about food by providing clear nutritional info, so they can manage diets (e.g., track calories, avoid allergens, choose nutrient - dense options).
# Answer:
- NLEA: Nutrition Labeling and Education Act.
- Passed: 1990.
- Affect on consumers: Requires nutrition labels on packaged foods (with calories, nutrients, etc.) and regulates health claims, enabling informed food choices (e.g., diet management, allergen avoidance).

### 4. Why does the body need fats?
# Brief Explanations:
Fats are a major energy source (provide 9 kcal/g, more than carbs/protein). They insulate the body (retain heat), protect organs (cushion them from injury), help absorb fat - soluble vitamins (A, D, E, K), and are used to make hormones (like steroid hormones) and cell membranes (phospholipids in cell walls).
# Answer:
The body needs fats for: energy (9 kcal/g, efficient fuel); insulation (retain heat); organ protection (cushion organs); fat - soluble vitamin absorption (A, D, E, K); hormone production (e.g., steroid hormones); and cell membrane structure (phospholipids).

### 5. Which three types of elements make up fats?
# Brief Explanations:
Fats (lipids, specifically triglycerides) are made of carbon (C), hydrogen (H), and oxygen (O). Triglycerides consist of glycerol (a 3 - carbon alcohol with - OH groups) and fatty acids (long chains of C and H with a - COOH group), so the elements are C, H, O.
# Answer:
Fats (triglycerides) are made of **carbon (C)**, **hydrogen (H)**, and **oxygen (O)**.

### 6. Give four examples of saturated fats.
# Brief Explanations:
Saturated fats have single bonds in fatty acid chains, are solid at room temp (usually from animal sources or tropical oils). Examples: butter (from dairy), lard (pig fat), coconut oil, palm oil. Also, fat in red meat (like beef fat) or shortening (hydrogenated, but some shortenings use saturated fats).
# Answer:
Four examples of saturated fats: butter (dairy fat), lard (pig fat), coconut oil, palm oil (or beef fat, shortening).

### 7. Give two examples of unsaturated fats.
# Brief Explanations:
Unsaturated fats have one (mono) or more (poly) double bonds, are liquid at room temp (mostly plant - based, or fish). Examples: olive oil (monounsaturated), canola oil (monounsaturated), salmon oil (polyunsaturated, omega - 3), sunflower oil (polyunsaturated, omega - 6).
# Answer:
Two examples of unsaturated fats: olive oil (monounsaturated), salmon oil (polyunsaturated, omega - 3) (or canola oil, sunflower oil).

### 8. What is the difference between monounsaturated fats and polyunsaturated fats?
# Brief Explanations:
Monounsaturated fats have **one double bond** in their fatty acid carbon chain (e.g., olive oil, canola oil). Polyunsaturated fats have **two or more double bonds** (e.g., sunflower oil, salmon oil with omega - 3/6). The number of double bonds affects their structure, melting point, and health impacts (polyunsaturated fats like omega - 3s are linked to heart health).
# Answer:
- Monounsaturated fats: Have **one double bond** in the fatty acid carbon chain.
- Polyunsaturated fats: Have **two or more double bonds** in the fatty acid carbon chain.

### 9. Explain what could happen to your body if you consumed too much fat.
# Brief Explanations:
Excess fat (especially saturated/trans fats) leads to weight gain (high calorie density: 9 kcal/g). It can cause high blood cholesterol (LDL “bad” cholesterol rises), increasing risk of heart disease (atherosclerosis: plaque in arteries). Also, obesity - related issues: type 2 diabetes (insulin resistance), joint strain, and some cancers (e.g., breast, colon) are linked to high fat diets (especially unhealthy fats). Liver issues (fatty liver disease) can occur as the liver stores excess fat.
# Answer:
Consuming too much fat (especially unhealthy fats) causes: weight gain (high calorie density); high blood cholesterol (LDL rise) → heart disease (atherosclerosis); obesity - related problems (type 2 diabetes, joint strain); increased cancer risk (e.g., breast, colon); and fatty liver disease (liver fat accumulation).
