Katharine Hepburn, a Hollywood icon known for her independence and spirited personality, also embodied a philosophy of simple, fuss-free living. Her approach to diet and exercise, characterized by a reverence for real food, a love of chocolate, and a commitment to physical activity, offers valuable lessons for aging with grace and maintaining vitality.
Hepburn's Philosophy: Simplicity and Enjoyment
Hepburn's strategy in life, as reflected in her approach to health, was essentially a no-fuss and simple one. She believed in eating real food without obsessing over it, and famously enjoyed chocolate. This aligns with the modern understanding that a balanced diet should be sustainable and enjoyable, rather than restrictive and stressful.
The Importance of Protein in Aging
While Hepburn may not have explicitly focused on specific macronutrient ratios, modern nutritional science highlights the importance of protein, especially as we age. From around the age of 30, we begin to lose muscle mass at a rate of 3-8% per decade. Adequate protein intake is crucial for maintaining muscle mass, immune function, and brain health, as these processes rely on amino acids derived from protein.
A senior person weighing 65kg, for example, may need just shy of 100 grams of protein per day. Good sources include salmon (approximately 25g of protein per 100g) and eggs (about 7g of protein per egg). It's important to consume a variety of protein-rich foods throughout the day to ensure a diversity of amino acids.
Tryptophan, an essential amino acid, is particularly important in aging as it supports the immune system and is needed for the production of serotonin and melatonin, vital for sleep and mood regulation. Adequate protein intake can therefore contribute to better sleeping patterns and improved mood.

For those following plant-rich diets, it's essential to consider plant-based protein sources that provide all the essential amino acids. Legumes and nuts are excellent options.
Seaweed as a Novel Protein Source
Emerging research highlights the potential of seaweed as a protein source. Studies have shown that certain types of seaweed, when grown in ideal conditions, can contain up to 40% protein in their dried form. Protein-rich seaweed ingredients can contain up to 60% protein. Incorporating seaweed into the diet, through products like muesli or even stirred into mashed potatoes, can add nutritional value and contribute to daily protein intake.
Seaweed is also rich in other beneficial components such as B12 and trace elements like iron. Ongoing research is exploring the protein profile, digestibility, and bioavailability of seaweed, as well as its potential applications in various food products.
The Importance of Balance and Whole Foods
While protein is crucial, it's important to remember that balance is key. Excessively high-protein diets (greater than 2g/kg of weight for most people) that lack other essential nutrients, particularly carbohydrates and glycan fibers for gut health, can be detrimental. Consuming a whole-food diet makes it easier to achieve a balanced intake of all necessary nutrients.
Hepburn's approach of "don't be fussy about it" aligns with the idea of focusing on whole, unprocessed foods and avoiding restrictive dieting.

Hepburn's Exercise Regimen: A Lifelong Commitment to Activity
Katharine Hepburn was known for her enviable trim figure and maintained her fitness well into her later years. At 84, she claimed to still be able to stand on her head and walk on her hands. Her parents encouraged her to exercise her body "to its fullest potential," and she embraced this philosophy throughout her life.
Unlike many leading ladies of her time, Hepburn enjoyed vigorous exercise. She was said to enjoy a wide variety of sports, especially swimming, tennis, and golf. She often exercised before dawn to fit it into her busy schedule. When at her parents' home in Fenwick, Connecticut, she would practice her diving skills in the ocean, even when the water was cold.
Hepburn's dedication to exercise continued as she aged. She continued doing her own stunts well into her 60s. Her commitment to fitness likely allowed her to enjoy her favorite foods, including brownies, without compromising her health.
Hepburn's Advice on Life and Well-being
Hepburn's lifestyle blog, "HEP," offered tips for healthy living, emphasizing gratitude and a no-nonsense approach. She advocated for stick-to-it-iveness and believed in facing challenges head-on. She famously jumped into an ice pool and swam 150 laps before dawn every morning, followed by exercises with a medicine ball.
She eschewed elaborate fashion and preferred simple, practical clothing. She also believed in plain food and dismissed the hype around gluten and trendy diets, favoring a simple breakfast of muesli and prune compote and a lunch of a hard roll and cheddar cheese. While she allowed herself a shot of Jameson's in the evening, she considered the trends that people go crazy for a national disgrace.
