Red Produce: For Heart and Blood Health

Red fruits and veggies get their vibrant hue from antioxidants called lycopene and anthocyanins.

These compounds protect your ticker and your entire circulatory system in several ways. For example, research shows that the lycopene in tomatoes, watermelon, and pink grapefruit helps:

  • Prevent LDL “bad” cholesterol from becoming oxidized and damaging artery walls
  • Reduce inflammation that can lead to cardiovascular disease
  • Lower blood pressure
  • Improve blood flow

The anthocyanins that make cherries, raspberries, strawberries, and red cabbage so rosy boast all those benefits, too.

They also stabilize collagen and strengthen blood vessels to boost overall circulatory health.

Remember when you’re shopping for ruby-red produce?

More Intense Color = More Nutrients

Deeper, darker shades of crimson contain higher concentrations of heart-helping antioxidants. So choose the ripest, reddest varieties you can find!

Here are some easy, tasty ways to pump up the red foods in your routine:

  • Add raspberries, strawberries, or red grapefruit slices to a spinach salad
  • Blend cherries or pomegranate seeds into smoothies
  • Roast beets and red onion wedges for a flavorful side dish
  • Stuff bell peppers with ground turkey, brown rice, tomatoes and spices

Orange and Yellow Produce: For Immunity and Eye Health

Orange foods like carrots, pumpkins, mangoes, and apricots get their vibrant color from beta-carotene, a powerful antioxidant.

As its name suggests, it can be converted to active vitamin A inside your body. Vitamin A keeps your vision sharp, supercharges immunity, and helps maintain healthy skin and tissues.

Yellow foods like lemons, pineapple, yellow peppers, and squash also supply immune-strengthening vitamin C and vision-guarding compounds called lutein and zeaxanthin.

Lutein and “zee-ah-zan-thin” accumulate in eye tissues and filter harmful blue light that can damage retinas.

Research suggests getting plenty in your diet can lower risks of cataracts and age-related macular degeneration.

What are the ways to pump up orange and yellow varieties?

  • Whip up carrot-ginger soup or carrot-apple muffins
  • Mix yellow bell pepper strips into a rice or quinoa salad
  • Snack on orange slices, pineapple chunks, or mango with a handful of unsalted nuts
  • Jazz up tacos with mango salsa and yellow pepper strips
  • Blend pumpkin or sweet potatoes into smoothies for creaminess

Tip: Cooking Veggies Boosts Nutrient Absorption

Your body soaks up more beta-carotene and other antioxidants from cooked or pureed orange/yellow produce compared to raw.

So, while crunchy carrot sticks make a fine snack, eating cooked carrots, pumpkin pie, or carrot soup provides superior nutrition!

Green Produce: For Detoxification and Anti-Cancer Benefits

From avocados to zucchini—green produce is packed with health defenders! For one, green veggies and fruits provide chlorophyll, the pigment that gives plants their verdant color.

Some fascinating research suggests chlorophyll helps block toxins and carcinogens from binding to DNA in the body.

This protective action occurs in isolation and also sparks more extensive detoxificationn processes in cells.

Additionally, virtually all green plant foods deliver:

  • Immune-boosting vitamin C
  • Bone-building vitamin K
  • Anti-inflammatory nutrients like omega-3s (in green leafy vegetables) and magnesium
  • Fiber for healthy digestion and weight regulation
  • Antioxidants and phytochemicals that combat diseases like heart disease and type 2 diabetes

Some easy ways to pile your plate with green goodness:

  • Add avocado chunks or slices to sandwiches and burgers
  • Blend spinach or kale into fruit smoothies.
  • Snack on grapes, kiwis, or honeydew melon
  • Stir-fry broccoli, sugar snap peas, asparagus and other veggies
  • Toss a mixed green salad with lemon juice and olive oil

Remember Leafy Greens

Leafy green veggies like spinach, romaine, kale, arugula, chard, and collard greens are concentration camps for nutrients compared to other colors. Be sure to work them into your healthy rainbow regularly!

Blue and Purple Produce: To Protect Memory and Lower Alzheimer’s Risk

The anthocyanin antioxidants that give blueberries, blackberries, plums, eggplant, and purple cabbage their dramatic hue also guard brain cells and cognitive function. Population studies link higher anthocyanin intake to:

  • Up to a 32% lower risk of dementia and Alzheimer’s disease
  • Enhanced short-term memory and coordination
  • Improved focus, information processing, and decision making

The unique combination of antioxidants in purple and blue foods also helps safeguard DNA structure.

This cellular protection translates to lower risks for several cancers—including colon, esophageal, and prostate tumors.

Lastly, many blue/purple fruits and veggies have anti-inflammatory, antimicrobial, and antiviral properties. So eating more of them supports immune strength, to boot!

Ideas for eating more blue/purple produce:

  • Start your day with a blueberry muffin or smoothie
  • Mix purple cabbage into coleslaw
  • Roast eggplant and red onion together
  • Snack on blackberries, blueberries, or red grapes

Frozen Berries = Fresh Berries

Frozen blueberries, strawberries, blackberries, raspberries, and other berries retain their nutritional content and anthocyanin levels equally as well as fresh. Stock up when you see sales!

White Produce: Immunity, Heart Health and Phytochemicals

White, tan, and brown fruits and vegetables complete the healthy rainbow, providing an array of nutrients.

For example, immune-boosting zinc and vitamin C abound in cauliflower, jicama, mushrooms, bananas, and brown pears.

Heart-helping potassium and fiber bulk up white peaches, apples, turnips, garlic, and mushrooms. And don’t forget about the numerous protective phytochemicals found across white produce categories!

Allium vegetables like onions, leeks, shallots, and garlic contain anti-inflammatory and antimicrobial sulfur compounds.

Fungi like mushrooms and offer proteins along with B vitamins. Apples, pears, and stone fruits serve up antioxidants like quercetin, hydroxycinnamic acid, and catechins.

Together with the other rainbow colors, these whites, tans, and browns help round out a balanced, nutrient-dense diet.

A few easy ways to add more white fruits and veggies:

  • Whip up mushroom stroganoff
  • Bake chicken topped with banana slices and pineapple
  • Stir fry bok choy or napa cabbage
  • Roast cauliflower florets seasoned with cumin and garlic
  • Mix apples or pears into salads or eat as-is for snacks
