Eating well does not require extreme dieting or complicated rules. It requires meeting evidence-based daily targets across core food groups while controlling added sugar, sodium, and saturated fat. Below is a structured breakdown aligned with U.S. Dietary Guidelines, followed by a realistic one-day sample meal plan.

---

1. Vegetables: 2–3 Cups Per Day

Why it matters: Vegetables provide fiber, potassium, folate, antioxidants, and phytochemicals that reduce cardiometabolic risk.

Daily target:

• 1 cup raw or cooked vegetables
• 2 cups raw leafy greens = 1 cup equivalent
• Include at least:
  • 1 leafy green serving
  • 1 colorful vegetable (carrot, bell pepper, beet, squash)

Strategy: Distribute across meals instead of relying on dinner only.

---

2. Fruits: 1.5–2 Cups Per Day

Why it matters: Whole fruits provide fiber and micronutrients without the glycemic spike of juice.

Daily target examples:

• 1 medium apple or orange
• 1 cup berries
• ½ large banana

Best practice: Choose whole fruit. Limit juice due to concentrated sugars.

3. Protein Foods: 5–6.5 oz Equivalents Per Day

Why it matters: Supports muscle maintenance, metabolic function, and satiety.

Examples of 1 oz equivalent:

• 1 oz cooked meat, poultry, or fish
• 1 egg
• ¼ cup beans or tofu

Minimum protein requirement:
~0.36 g per pound bodyweight (RDA).
Many active adults benefit from more (0.5–0.7 g/lb depending on goals).

Diversify sources: Include seafood, poultry, legumes, eggs, nuts.

4. Grains: 6 oz Equivalents Per Day

At least 50% from whole grains.

1 oz equivalent:

Choose low-fat or unsweetened options. Fortified plant milks are acceptable alternatives.

Keep saturated fat under 10% of total calories.

7. Hydration

• 2–3 liters of water daily
• Increase with exercise, heat, or high fiber intake.

8. Limits to Respect

• Sodium: < 2,300 mg/day
• Added sugar: < 10% of calories (~50 g max at 2,000 kcal)
• Fiber target:
  • Women: 22–28 g/day
  • Men: 34–38 g/day
