Anti-Inflammatory Diet
A whole-foods pattern designed to lower chronic, low-grade inflammation by emphasizing omega-3s, polyphenols, fiber, and minimizing ultra-processed foods, sugar, and seed oils.
The anti-inflammatory diet is not a single protocol but a synthesis of the patterns most consistently linked to lower inflammatory markers (CRP, IL-6, TNF-alpha) in human studies — Mediterranean-style eating, oily fish, abundant polyphenols, and low intake of ultra-processed foods, refined sugar, industrial seed oils, and excessive alcohol.
Foods to emphasize
Fatty fish 2–3x/week (salmon, sardines, mackerel, herring)
Extra-virgin olive oil
Berries, cherries, and other deeply colored fruit
Dark leafy greens and cruciferous vegetables
Turmeric, ginger, and culinary herbs
Green tea
Nuts (especially walnuts) and seeds (flax, chia)
Legumes and whole grains
Dark chocolate (≥70% cocoa) in moderation
Foods to avoid
Sugar-sweetened beverages and refined sugar
Ultra-processed snacks and ready meals
Industrial seed oils used at high heat (soybean, corn, sunflower, cottonseed)
Processed and cured meats
Refined flour products
Excess alcohol
Key principles
Cook with olive oil, finish with extra-virgin olive oil
Aim for 25–35 g of fiber per day from whole foods
Eat the rainbow — color diversity ~ polyphenol diversity
Limit added sugar to <25 g/day
Typical duration: A long-term eating pattern.
Why it may help
Beauty & Anti-Aging: Polyphenol- and omega-3-rich diets are linked with better skin elasticity, hydration, and reduced photoaging markers.
Skin Care: Reduces inflammatory drivers of acne, rosacea, and eczema; commonly recommended alongside topical care.
Cancer (Adjunctive Support): Lower dietary inflammatory index scores are associated with reduced incidence of multiple cancers in large cohorts.
Type 2 Diabetes: Reduces systemic inflammation that drives insulin resistance and beta-cell dysfunction.
Insulin Resistance: Reduces chronic low-grade inflammation that impairs insulin signaling.
Prediabetes: Lowers inflammatory markers linked to insulin resistance and metabolic progression.
Safe and flexible. Can be combined with Mediterranean, vegetarian, or plant-forward patterns.
Ketogenic Diet
Very-low-carbohydrate, high-fat eating pattern that shifts the body into ketosis, using ketones from fat as a primary fuel.
A classical ketogenic diet typically provides ~70–80% of calories from fat, ~15–20% from protein, and only ~5–10% (often 20–50 g/day) from carbohydrates. The metabolic shift to ketosis lowers blood glucose and insulin, raises ketone bodies (beta-hydroxybutyrate, acetoacetate), and is being studied for neurological and metabolic conditions. Variants include the Modified Atkins Diet (MAD), Medium-Chain Triglyceride (MCT) ketogenic diet, and the Low Glycemic Index Treatment (LGIT).
Foods to emphasize
Fatty fish (salmon, sardines, mackerel)
Pasture-raised eggs
Avocado and olives
Extra-virgin olive oil, coconut oil, MCT oil
Grass-fed meat and poultry
Full-fat dairy (butter, ghee, hard cheeses)
Nuts and seeds (macadamia, pecan, walnut, chia, flax)
Low-carb leafy greens and cruciferous vegetables
Bone broth and electrolyte-rich foods
Foods to avoid
Sugar and sweetened beverages
Grains and starches (bread, pasta, rice, cereal)
Most fruit (except small portions of berries)
Legumes and beans
Starchy vegetables (potatoes, corn, peas)
Low-fat or sweetened dairy
Vegetable seed oils (soybean, corn, sunflower) in excess
Most processed and packaged foods
Key principles
Carbohydrate intake usually 20–50 g net carbs per day
Adequate protein (~1.2–1.7 g/kg) — not high-protein
Most calories from whole-food fats
Track electrolytes (sodium, potassium, magnesium) to prevent "keto flu"
Best initiated with clinician guidance if on medications for diabetes, blood pressure, or seizures
Typical duration: Often 3–6 months minimum to assess response; medically supervised protocols (e.g. for epilepsy) may be maintained for years.
Why it may help
Cancer (Adjunctive Support): Investigated as an adjunctive metabolic therapy alongside standard oncology care — most evidence is preclinical or early-phase, with some glioma and glioblastoma trials. Should only be used under oncology and dietitian supervision.
Type 2 Diabetes: Significant HbA1c and fasting glucose reductions in clinical trials. Monitor diabetes medications closely to avoid hypoglycemia.
Prediabetes: Rapid improvements in fasting glucose and HbA1c, often reversing prediabetes within months.
Insulin Resistance: Most direct mechanism — lowers insulin demand by minimizing carbohydrate load.
Ketogenic therapy is a medical intervention when used for seizure disorders or oncology — work with a clinician or registered dietitian experienced in ketogenic therapy. Not recommended in pregnancy, type 1 diabetes without supervision, pancreatitis, certain fatty-acid oxidation disorders, or active eating disorders.
Vegan Diet
A fully plant-based eating pattern that excludes all animal products — meat, fish, dairy, eggs, and honey.
A whole-food vegan diet emphasizes vegetables, fruit, legumes, whole grains, nuts, and seeds. It has been associated with improvements in body weight, blood lipids, and glycemic control, and is being studied for autoimmune and inflammatory conditions. It requires deliberate planning for vitamin B12, vitamin D, omega-3 (EPA/DHA), iodine, iron, zinc, and (sometimes) calcium.
Nuts and seeds (especially walnuts, chia, flax, hemp)
Fortified plant milks and nutritional yeast
Algae-based EPA/DHA supplement
Vitamin B12 supplement (non-negotiable)
Foods to avoid
Refined grains and sugar as the bulk of meals
Heavily processed vegan junk foods
Coconut and palm oils in excess
Key principles
B12 supplementation is required, not optional
Include a reliable iodine source (iodized salt or seaweed in moderation)
Get vitamin D from sun and/or a supplement
Combine grains and legumes across the day for complete protein
Choose calcium-fortified plant milk if not eating leafy greens daily
Typical duration: A long-term eating pattern.
Why it may help
Cancer (Adjunctive Support): Vegan cohorts show some of the lowest incidence rates of cancer in observational data, particularly for hormone-related and GI cancers.
Skin Care: Eliminating dairy has reduced acne severity in clinical studies; whole-food vegan diets push this further with high antioxidant intake.
Type 2 Diabetes: Improves insulin sensitivity, supports weight loss, and lowers CV risk in T2D. Supplement B12.
Vegan diets can be excellent or deficient — quality depends on planning. Pregnant, breastfeeding, and growing children on vegan diets should be followed by a registered dietitian.
Vegetarian Diet
A plant-based eating pattern that excludes meat, poultry, and fish but typically allows eggs and/or dairy.
Vegetarian diets range from lacto-ovo (includes eggs and dairy) to lacto (dairy only) and ovo (eggs only). Done well, they are associated with lower rates of cardiovascular disease, type 2 diabetes, and some cancers. Done poorly, they can be high in refined grains and low in key nutrients (B12, iron, omega-3s, zinc).
Foods to emphasize
Legumes (lentils, chickpeas, beans, tofu, tempeh)
Whole grains (oats, quinoa, brown rice, whole wheat)
Vegetables and fruit, daily and varied
Nuts and seeds (almonds, walnuts, chia, flax, hemp)
Plan for protein at every meal (legumes, tofu, tempeh, eggs, dairy)
Pair iron-rich plants with vitamin C to boost absorption
Plan a reliable B12 source — fortified foods or a supplement
Include omega-3 ALA from flax, chia, walnuts; consider an algae-based EPA/DHA supplement
Typical duration: A long-term eating pattern.
Why it may help
Cancer (Adjunctive Support): Long-term cohorts (Adventist Health Study, EPIC-Oxford) associate vegetarian patterns with lower incidence of several cancers, especially colorectal.
Beauty & Anti-Aging: High intake of plant antioxidants is linked with better skin antioxidant capacity and lower oxidative stress markers in observational studies.
Nutritional adequacy depends on planning, not just food choice. A registered dietitian can help avoid common gaps.
Autoimmune Protocol (AIP)
A strict elimination version of paleo designed to calm autoimmune flares and identify food triggers through structured reintroduction.
The Autoimmune Protocol removes foods commonly implicated in immune activation and gut permeability — grains, legumes, dairy, eggs, nightshade vegetables, nuts, seeds, refined sugar, alcohol, and additives — for a 30–90 day elimination, followed by careful one-at-a-time reintroduction. It is most studied in Hashimoto's thyroiditis and inflammatory bowel disease.
Foods to emphasize
Quality meat, poultry, and seafood (especially wild-caught fatty fish)
Organ meats once or twice weekly
A wide variety of non-nightshade vegetables and leafy greens
Nuts and seeds (including seed-based spices like cumin, coriander)
Refined sugar and sweeteners
Alcohol
NSAIDs and food additives where possible
Key principles
Pair the elimination with sleep, stress management, and movement
Track symptoms in a journal during reintroductions
Reintroduce one food every 5–7 days and watch for symptom changes
Most people do NOT need to stay strict long-term — the goal is a personalized maintenance diet
Typical duration: 30–90 day strict elimination, then a structured staged reintroduction over weeks to months.
Why it may help
Skin Care: Used as an elimination protocol for chronic eczema, psoriasis, and autoimmune skin conditions where food triggers are suspected.
AIP is restrictive and best done with a practitioner familiar with the protocol, especially when active autoimmune disease is involved or in pregnancy/lactation.
Carnivore Diet
An all-animal-foods elimination diet consisting of meat, fish, eggs, and (optionally) dairy, with zero plant foods.
The carnivore diet is the most aggressive elimination diet — it removes every plant food (and therefore every fiber, lectin, oxalate, gluten, and FODMAP source) to isolate animal-food tolerance. Proponents use it primarily as a short-term diagnostic elimination to surface food triggers in autoimmune, gut, and inflammatory conditions. Long-term safety data is limited and observational.
Foods to emphasize
Ruminant meat (beef, lamb, bison) — emphasized for nutrient density
Pasture-raised eggs
Fatty fish (salmon, sardines)
Organ meats (liver, kidney) once or twice weekly
Bone broth and bone marrow
Animal fats (tallow, butter, ghee)
Salt to taste
Optional: aged hard cheeses, heavy cream
Foods to avoid
All grains, legumes, and seeds
All vegetables and fruit
Nuts and plant oils
Sugar and sweeteners
Most processed foods
Alcohol
Key principles
Eat to satiety — no calorie counting
Salt food liberally to maintain electrolytes
Prioritize fattier cuts over lean meats
Reintroduce foods one at a time after the elimination window to identify triggers
Best tracked with a clinician given the radical nature of the change
Typical duration: Typically run as a 30–90 day elimination, then food reintroductions one at a time.
Why it may help
Skin Care: Reported anecdotally to clear chronic skin inflammation by removing common food triggers; used as a short diagnostic elimination, not a long-term plan.
Long-term effects on cardiovascular markers, bone health, and the gut microbiome are not well established. Avoid in chronic kidney disease, gout flares, or active eating disorders without medical supervision.
Linked nutrient deficiencies
Vitamin and mineral deficiencies commonly associated with the conditions this remedy may support.
Vitamin C
Water-soluble vitamin
Antioxidant required for collagen synthesis, immune function, and iron absorption.
Low zinc is linked to recurrent infections, acne, slow wound healing, leaky gut, and impaired taste/smell. Often deficient in vegetarians and those with gut malabsorption.
Common symptoms
Frequent colds/infections
Acne or slow-healing skin
Loss of taste or smell
Hair loss
White spots on nails
Food sources
Oysters
Beef and lamb
Pumpkin seeds
Cashews
Lentils and chickpeas
Lab markers to discuss
Plasma or serum zinc
Zinc/copper ratio
Reference intake: 8–11 mg/day RDA.
Supplementation notes: Take away from iron and calcium. Long-term high-dose zinc depletes copper — pair with ~1 mg copper if dosing >30 mg/day.
Why it matters here
Skin Care: Low zinc is implicated in acne, eczema, and slow wound healing.
Beauty & Anti-Aging: Required for wound healing and collagen formation.
Vitamin D
Fat-soluble vitamin
Hormone-like vitamin central to immune function, mood, bone, and thyroid health.
Low vitamin D status is one of the most widespread deficiencies globally and has been linked to autoimmune disease activity (Hashimoto's, MS), mood disorders, recurrent infections, and poor skin barrier function.
Common symptoms
Fatigue
Low mood
Frequent infections
Bone or muscle aches
Hair thinning
Food sources
Fatty fish (salmon, sardines)
Egg yolks
Cod liver oil
UV-exposed mushrooms
Fortified dairy
Lab markers to discuss
25-hydroxyvitamin D (target 40–60 ng/mL per most functional ranges)
Reference intake: Adults 600–800 IU/day RDA; functional medicine often targets 2,000–5,000 IU/day with monitoring.
Supplementation notes: Take with a fat-containing meal. Pair with vitamin K2 (MK-7) when supplementing higher doses long-term.
Why it matters here
Cancer (Adjunctive Support): Observational and some interventional data link adequate vitamin D to improved outcomes in several cancers.
Skin Care: Supports skin barrier and immune balance.
Beauty & Anti-Aging: Influences skin barrier function and pigmentation pathways.
Vitamin A (Retinol)
Fat-soluble vitamin
Required for epithelial integrity, immune defense, vision, and skin renewal.
Selenium reduces TPO antibodies in Hashimoto's and supports T4→T3 conversion. Deficiency is implicated in thyroid autoimmunity and viral susceptibility.
Green tea appears to exert its effects primarily through its antioxidant and anti-inflammatory compounds, which may help protect cells from damage and modulate various biological pathways.
How it works in more detail
The main active compounds, catechins (especially epigallocatechin gallate or EGCG), appear to act as potent antioxidants, neutralizing free radicals and reducing oxidative stress. EGCG has been studied for its potential to inhibit 5-alpha reductase and matrix metalloproteinases, which are enzymes implicated in processes such as skin aging. Further, green tea compounds may influence cellular signaling pathways and gene expression, as observed in some preclinical models.
How to use
Always consult a qualified clinician.
Editorial guidance
Suggested dosage
2–3 cups/day brewed, or 300–500 mg/day of standardized EGCG extract.
Research dosage range
300-1000 mg/day of EGCG, or 3-5 cups of brewed green tea daily
Typical onset
Some acute effects, such as a mild stimulant effect due to caffeine, may be felt relatively quickly. However, any sustained health benefits from green tea are generally thought to require consistent, long-term consumption over weeks to months.
Typical forms
tea bags, loose leaf tea, capsule, extract
Quality markers
For green tea supplements, look for products standardized to a specific percentage of catechins, particularly EGCG, to ensure consistent potency. Reputable brands often provide third-party testing for purity and absence of contaminants. Organic certification may indicate fewer pesticide residues.

Weight regain after a successful weight loss intervention is very common. Most studies show that, on average, the weight loss attained during a weight loss intervention period is not or is not fully maintained during follow-up. We review what is currently known about dietary strategies for weight loss maintenance, focusing on nutrient composition by means of a systematic review and meta-analysis of studies and discuss other potential strategies that have not been studied so far. Twenty-one studies with 2875 participants who were overweight or obese are included in this systematic review and meta-analysis. Studies investigate increased protein intake (12 studies), lower dietary glycemic index (four studies), green tea (three studies), conjugated linoleic acid (three studies), higher fibre intake (three studies), and other miscellaneous interventions (six studies). The meta-analysis shows a significant beneficial effect of higher protein intake on the prevention of weight regain (SMD (st

Non-alcoholic fatty liver disease (NAFLD) has recently emerged as a challenging metabolic disorder with a strong emphasis on its prevention and management. Polyphenols, a group of naturally occurring plant compounds, have been associated with a decreased risk of various metabolic disorders related to NAFLD. The current systematic review aims to critically assess evidence about the ameliorative effect of polyphenol supplementation on NAFLD patients. A PRISMA systematic search appraisal was conducted in PubMed, Scopus, Web of Science Core Collection, and all relevant studies published prior to April 2024 and met the inclusion criteria were included. Twenty-nine randomized clinical trials (RCTs) comprised 1840 NAFLD patients. The studies primarily examined eleven phenolic compounds, including turmeric, curcumin, resveratrol, genistein, catechin, green tea extract, hesperidin, and silymarin. Turmeric and curcumin decreased liver enzymes, inflammatory cytokines, lipid profile, insulin resis

Patients with acne are interested in nutraceuticals as a potential treatment option. However, there is uncertainty regarding the efficacy and safety of these products.
To evaluate the evidence for oral nutraceuticals in the treatment of acne.
The PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science databases were searched from inception through January 30, 2023, to identify randomized clinical trials evaluating oral nutraceutical interventions (ie, vitamins and minerals, botanical extracts, prebiotics, and probiotics) in individuals with acne. Clinician-reported outcomes (eg, investigator global assessment, lesion counts), patient-reported outcomes (eg, quality of life), and adverse events were extracted from the included studies. The quality of evidence was assessed using the Cochrane Risk of Bias checklist tool for randomized clinical trials. Based on the Risk of Bias tool, articles were converted to Agency for Healthcare Research and Quality standards

BACKGROUND: Hyperpigmentation disorders are commonly encountered in dermatology clinics. Botanical and natural ingredients have gained popularity as alternative depigmenting products. OBJECTIVE: We sought to review clinical studies evaluating the use of different natural products in treating hyperpigmentation so clinicians are better equipped to educate their patients. Specific ingredients reviewed include azelaic acid, aloesin, mulberry, licorice extracts, lignin peroxidase, kojic acid, niacinamide, ellagic acid, arbutin, green tea, turmeric, soy, and ascorbic acid. METHODS: Systematic searches of PubMed and SCOPUS databases were performed in March 2016 using the various ingredient names, "melasma"and "hyperpigmentation." Two reviewers independently screened titles, leading to the selection of 30 clinical studies. RESULTS: Review of the literature revealed few clinical trials that evaluated the treatment of hyperpigmentation with natural ingredients. Despite the limited evidence-based

The effect of a combination of magnesium, vitamins B6, B9, B12, rhodiola and green tea/L-theanine (Mg-Teadiola) on stress was evaluated in chronically stressed, otherwise healthy individuals. Effects on stress-related quality-of-life parameters (sleep and perception of pain) were also explored. Adults with stress for ≥1 month, scoring ≥14 points on the Depression Anxiety Stress Scale (DASS)-42 questionnaire, were randomized (1:1) to receive oral Mg-Teadiola (n = 49) or a placebo (n = 51), for 28 days, with a follow-up assessment on Day 56 (NCT04391452). The primary endpoint was the change in the DASS-42 stress score from baseline to Day 28 with Mg-Teadiola versus placebo. The DASS-42 stress scores significantly decreased from baseline to Day 28 with Mg-Teadiola versus placebo (effect size, 0.29; 95% CI [0.01, 0.57]; p = 0.04). Similar reductions were observed on Day 14 (p = 0.006) and Day 56 (p = 0.02). A significant reduction in sensitivity to cold pain (p = 0.01) and a

Background and objective: Tea is the second most consumed drink in the world after water. Gingivitis is among the most common infectious diseases. In this clinical study, Chlorhexidine Gluconate (CHX) was chosen as the positive control group and the clinical and biochemical efficacy of mouthwashes with green tea, white tea and essential oil (EO) as the active ingredients were aimed to be examined comprehensively.
Methods: 112 participants with gingivitis were randomly assigned to 4 different groups that different mouthwashes were used for 4 weeks. CHX-MW group (0.12% CHX, as a positive control group), EO-MW group (Listerine), GT-MW group (5% Green tea), and WT-MW group (5% White tea). The effects of the mouthwashes on plaque, inflammation, and dental staining were evaluated by indexed scores at the beginning and the end of the 4th week. In addition, markers related to gingival inflammation (IL-1beta, MMP-8) and oxidative stress (TOS, TAS, OSI (TOS/TAS)) were evaluated on samples from the gingival crevicular fluid.
An explosion of interest in the numerous therapeutic properties of Punica granatum over the last decade has led to numerous in vitro, animal, and clinical trials. Pomegranate is a potent antioxidant, superior to red wine and equal to or better than green tea. In addition, anticarcinogenic and anti-inflammatory properties suggest its possible use as a therapy or adjunct for prevention and treatment of several types of cancer and cardiovascular disease. Because of pomegranate's antimicrobial properties, it may aid in preventing infection by dental pathogens, pathogenic E. coli O157:H7, and antibiotic-resistant organisms such as methicillin-resistant Staphylococcus aureus (MRSA) Pomegranate's effect on bacterial pathogens has only been tested in vitro, however, necessitating human trials to refute or substantiate any clinical effect.
The possibility that pomegranate extracts may also have an effect on several other disease processes, such as Alzheimer's and obesity, underscores the need for more clinical research. Currently, numerous clinical trials are in progress exploring the therapeutic potential of pomegranate extracts.
Aim The investigators want to evaluate the effect of Punica granatum components on Chronic sinusitis, nasal polyps and chronic rhinitis.
