Dietary guidelines - what are they?

• Definition: They're set instructions about what foods, meals, or food groups a country's people should focus on for a balanced diet.
• Purpose: Turning scientific understanding of a healthy diet into real-world advice for folks.

But hey, why don't all countries have the same guidelines? 🌍

• It's because of factors like
  • Religious beliefs: Some religions have specific foods they avoid.
    • E.g., Muslims avoid pork.
  • Social norms: Like how it's normal in some countries to have a siesta after lunch.
  • Preparation preferences: Sushi in Japan vs. BBQ in the US!
  • Food consumption patterns: Ever noticed how some countries prefer rice, while others prefer bread?
  • Food availability: It’s easier to get mangoes in India than in Iceland!
  • Food security: Does everyone have easy access to food?
  • Income & food prices: Can people afford the recommended food?

Every country has its own cool way of showing these guidelines:

• 🇦🇺 Australia uses a food pyramid.
• 🇰🇷 Korea has a food tower.
• 🇫🇮 Finland prefers a food circle.
• 🇯🇵 Japan goes for a spinning top.
• 🇨🇦 Canada has a beautiful rainbow.
• 🇬🇧 UK uses a simple food plate.

Differences in Dietary Needs: Athletes vs. Non-Athletes

• Energy & Fluid Needs: Athletes need more because they burn more and sweat more!
• Type of Sport: A weightlifter won't eat the same diet as a swimmer.
• Training, Competition, & Recovery: Athletes eat differently on rest days vs. game days.

Some Cool Science-y Stuff

• Endurance athletes (like those who run marathons 🏃‍♀️) need more carbohydrates in their diet.
  • Why? To meet energy demands for high-intensity events and delay tiredness.
  • Imagine trying to drive a car for a long journey without enough fuel! 🚗
• Most of their energy comes from carbs, leading to less energy from proteins and fats.
  • But, they still need slightly more proteins than non-athletes.
    • Why? For repairing and building muscles.
• Endurance athletes also need a bit more fats than their non-athlete buddies.
  • Fats provide energy, help absorb some vitamins, and offer essential fatty acids crucial for performance.
• Hydration: Super essential! Athletes should drink enough water to replace what they lose from sweating.
  • Think about how a plant droops without water. Now, imagine that's you without hydration during a workout! 🥤🌱

Study Tip: Imagine foods and nutrients as superheroes. Each has its own superpower that helps athletes perform at their peak! 🦸‍♂️🥦🍗

Remember: Nutrition is like the gas for your body's engine. You gotta fuel up right to zoom ahead! 🚀🍌🍗🥤🥦
