The 12 Healthiest Foods That You Need (Especially After 50)
In a Nutshell
After 50, declining stomach acid, reduced microbiome diversity, anabolic resistance, and rising inflammation make nutrient-dense, anti-inflammatory foods essential. Prioritize wild salmon/sardines for omega-3s, pasture-raised eggs and beef liver for choline and B12, fermented vegetables and kefir for microbiome diversity, and collagen-rich bone broth plus red meat for connective tissue and muscle support. Key supporting foods include arugula for nitric oxide, onions for quercetin, extra virgin olive oil for anti-inflammatory phytonutrients, aged cheese for K2-directed calcium, and dark chocolate (85%+) for gut barrier and cardiovascular benefits.

After 50, stomach acid becomes weaker, making it more difficult to absorb B12, break down protein, and pull in minerals. The full diversity of gut microbes decreases, reducing microbiome benefits. Anabolic resistance develops, making it harder to build muscle despite the same exercise routines. Inflammation increases throughout the body.
Wild salmon is recommended over farm-raised salmon. Sardines serve as a less expensive alternative. Both provide omega-3 fatty acids: EPA for reducing inflammation and DHA for brain health, as a significant portion of brain fats are made from DHA. Salmon is prepared by cutting into cubes and frying in butter until slightly crispy. Sardines should be purchased in extra virgin olive oil with bones and skin intact for additional collagen.
Pasture-raised eggs are recommended, and the whole egg including yolk should be consumed. Egg yolks contain more protein per volume than whites and have nearly the highest amount of choline, which prevents fatty liver and supports brain health by converting to acetylcholine, a key neurotransmitter. Eggs provide high-quality cholesterol needed for vitamin D production, bile, and cellular membranes. No credible evidence links dietary egg cholesterol to increased heart disease risk. Eggs are considered the perfect ketogenic food due to being very low in carbs while containing virtually every nutrient except vitamin C.
Both are super nutrient-dense foods. Cod liver is consumed rather than the oil. High-quality grass-fed beef liver provides even more nutrients and is the best source of B12 and the highest source of choline. Both provide co-enzyme Q10 for energy through mitochondrial support, which becomes increasingly needed with age.
A 2021 Stanford University study compared high-fiber diets versus fermented food diets including sauerkraut, kimchi, and other fermented vegetables. After 10 weeks, the fermented food group showed decreased levels of all 19 inflammatory markers, while the fiber group showed minimal change. High-quality fermented vegetables provide both fiber and microbiome benefits. Lacto-fermented pickles contain 100 million to 1 billion microbes per gram and appear cloudy, found in the refrigerated section. Regular vinegar pickles contain no microbes and lack cloudiness.
Kefir differs from yogurt, which contains only a couple bacterial strains that rarely survive stomach acids. Kefir is more acidic, allowing microbes to adapt and pass through stomach acidity into the small and large intestine. Kefir contains 30-56 different microbes including friendly bacteria and yeast that yogurt lacks. Goat milk kefir is considered the ultimate choice. Kefir contains tryptophan, which enhances melatonin production for better sleep. People with lactose intolerance can typically handle kefir because microbes consume most of the lactose.
Arugula tops the list for increasing nitric oxide, which benefits arteries and circulation. Arugula provides additional benefits for liver health. Garden-grown lettuce provides microbes that function like probiotics, unlike store-bought hydroponic or aeroponic lettuce.
Onions are consumed in large amounts and added to salads and burgers. Red and yellow onions provide different benefits. Onions contain quercetin, which helps clear zombie cells that cause inflammation and acts as an anti-inflammatory. The fiber and quercetin in onions serve as food for the microbiome.
Bone broth provides collagen, which decreases after age 50. Collagen comprises 30% of body protein, yet typical steak consumption provides only 2-3%. Collagen powder can be added to coffee. Collagen serves as raw material for building connective tissue in joints, tendons, and ligaments. Glycine, an important amino acid often deficient in people, can be obtained from bone broth and collagen. Glycine helps improve sleep by reducing body temperature by one degree.
Grass-fed, grass-finished red meat provides protein for structural and biochemical purposes. Red meat contains creatine for short bursts of exercise and carnitine for shuttling fatty acids into mitochondria. Carnitine levels decrease with age, making red meat increasingly beneficial.
Seafood provides trace minerals including zinc from oysters and selenium for thyroid function. Farmers typically add only three minerals (NPK - nitrogen, phosphorus, potassium) back to soil, leaving 90 additional trace minerals missing. Trace minerals act as co-factors for all biochemical processes.
Extra virgin olive oil creates a tickling or irritating sensation at the back of the throat. A specific phytonutrient inhibits the same enzymes as ibuprofen, helping reduce pain and inflammation.
Aged cheese is consumed daily and provides calcium in the proper form, healthy protein, and healthy fat. As a fermented product, aged cheese contains vitamin K2, which directs calcium to bones rather than soft tissues, joints, or arteries.
Dark chocolate or cacao with at least 85% cacao content is recommended. 90-95% of cacao is not absorbed in the small intestine and travels to the colon where gut microbes consume it. Cacao significantly increases nitric oxide for cardiovascular support. A 2025 Japanese randomized control trial found women eating dark chocolate daily increased from 2.75 to 4.95 bowel movements per week. Elite athletes consuming 40 grams of 85% dark chocolate daily for 30 days showed significant decreases in zonulin, a biomarker for leaky gut.
