What Martha Stewart (84) Eats to Look Decades Younger

She was the oldest cover model in Sports Illustrated Swimsuit Issue history. She posts selfies that regularly break the internet. And she still runs a media empire that would exhaust someone half her age.

So when Martha Stewart talks about what goes on her plate every single day, people pay attention. And the routine she has quietly maintained for over fifteen years is far simpler than anyone would expect.

The Morning Ritual She Has Never Skipped

Every morning, before anything else, Stewart blends a glass of green juice using produce she grows herself in a greenhouse on her property. Her recipe combines spinach, celery, parsley, cucumber, ginger, apple, lemon, and sometimes pomegranate juice, arugula, and fresh herbs.

She has kept this habit since at least 2009, and she treats it as non-negotiable no matter how early she wakes up or how packed the day ahead looks.

Why She Refuses to Call It Anti-Aging

In a 2021 interview with CNBC Make It, Stewart called the juice “an essential part of my everyday diet because it really does help with anti-aging. I don’t like the word ‘anti-aging’ — I say successful aging. And it also helps a lot with hair.”

The spinach and parsley in her blend deliver folate, vitamin K, and plant compounds linked to reduced inflammation, while the cucumber and celery keep the drink deeply hydrating without spiking blood sugar.

The Collagen Powder She Adds to Every Glass

Stewart does not stop at vegetables. She stirs collagen powder directly into her morning juice, a habit she has openly credited for supporting her skin over time.

Collagen production slows considerably as the body ages, and supplementing through powder has been linked in research to measurable improvements in skin elasticity, thickness, and hydration when taken consistently.

The Pescatarian Plate She Builds the Rest of the Day

Beyond the morning glass, Stewart follows a largely fish-based approach to eating. She has been direct about her preference, saying she does not eat much meat and gets most of her protein from seafood, particularly wild-caught salmon and tuna.

Her go-to lunch is a tuna salad made with Italian tuna packed in olive oil, fresh celery, crisp apple, shallots, and lemon juice, a combination she has described as a regular and reliable favorite.

The Olive Oil Cabinet That Says It All

Stewart keeps a dedicated cabinet in her kitchen specifically for olive oils, using extra virgin as her default fat for cooking, finishing dishes, and making dressings. It is a habit that closely mirrors the Mediterranean diet, the eating pattern most consistently linked to heart health, brain protection, and slower visible aging.

She has also insisted on growing as much as possible herself, tending a greenhouse year-round to produce the spinach, celery, parsley, and cucumbers that go directly into her daily glass.

That quiet combination of a raw morning ritual, homegrown produce, and a plate built around fish and olive oil is the answer Martha Stewart has been giving for decades. It just never came with a brand name attached.
