All berries reduce the risk of and fight cancer. Your best sources include fresh and frozen. Choose berries from the area you live in. Each part of the world has their own cancer prevention berry sources.

You should limit your consumption of fruit juices since they contain higher concentrations of sugars. A 1/4 cup or 125 ml (4 oz.) is the upper limit of acceptable calories since the liquids typically don’t contain fiber to blunt the sugar impact.

You should avoid fruit juices that contain added sugars/pear juice/apple juice/fructose since they are concentrated sugar sources.

When and if possible, you should choose organic sources to reduce your risk of pesticide and chemical exposure.

Beans and Legumes are a much-needed weapon against cancer.

Beans and legumes, the humble staples of many global cuisines, are gaining recognition in the scientific community for their potential role in reducing the risk and mortality of many diseases and cancer. This blog post will delve into the research behind these claims, shedding light on why I put beans and legumes in my Cancer Food Pyramid Tactic.

What are Beans and Legumes?

Beans and legumes are the fruits or seeds of a family of plants called Fabaceae. They are rich sources of fiber, essential vitamins and minerals, and plant-based protein. Common examples include chickpeas, lentils, peas, kidney beans, black beans, soybeans, pinto beans, navy beans, and peanuts.[1]

Nutritional Powerhouses

Beans and legumes are high in minerals and fiber without the saturated fat found in some animal proteins. They are rich in plant protein, fiber, B-vitamins, iron, folate, calcium, potassium, phosphorus, and zinc.

One cup (164 grams) of...

Nuts and Cancer

Nuts may be considered a cancer superfood because they contain additive and/or synergistic properties that contribute to reduced cancer risk.

Nuts are a rich source of monounsaturated and polyunsaturated fatty acids, tocopherols, antioxidant polyphenols, fiber, prebiotics, vegetable protein, minerals, and vitamins. The fiber and prebiotics can promote the growth of beneficial bacteria gut microbiome.[i] 

Nuts can decrease glucose, insulin, and inflammation levels.[ii] [iii] All of which can increase the risk or even stimulate cancer if elevated.

A human genetic study of women with breast cancer found consuming 2 oz (60 grams) of walnuts a day for 2 weeks improved 456 cancer prevention and cancer growth genetic pathways. Analysis of the data showed activation of pathways that promote apoptosis (normal cancer cell death), helped keep cancer cells in place and inhibited the pathways that promote activation of pathways that promote proliferation and migration....

Honey for Cancer Prevention?

Honey is a natural sweetener that has been used for thousands of years for its medicinal properties. More recently, there has been growing interest in the potential of honey to prevent cancer.

Honey contains several active compounds that have been shown to have anti-cancer properties. These include:

Methylglyoxal (MG): MG is a natural compound that has been shown to kill cancer cells in vitro and in animal studies.

Polyphenols: Honey is a rich source of polyphenols, which are plant compounds that have antioxidant and anti-inflammatory properties.

Flavonoids: Flavonoids are another type of polyphenol that has been shown to have anti-cancer properties.

Other compounds: Honey also contains other compounds with potential anti-cancer properties, such as propolis, royal jelly, and bee pollen.

Several studies have investigated the potential of honey to prevent cancer. One study, published in the journal "Cancer Prevention Research" in 2010, found that honey was...

Cooking Oil Smoke Point and Cancer

A cooking oil's smoke point is the temperature at which it begins to smoke visibly when heated. When an oil starts smoking it is oxidizing and could damage your body. 

A smoke point is the maximum safe cooking temperature. You should avoid heating the oil past this temperature. If you do heat past the smoke point you increase the risk of the oil turning brown, forming oxidized chemicals that can harm your body and increase your risk of cancer. People who work in kitchens and restaurants with cooking oils and poor ventilation have an increased lung cancer, colorectal cancer, and breast cancer risk.

Each oil manufacturer has a different chemical composition because of processing methods and each batch of fruit, vegetable and seed will vary. These factors will affect the smoke point. 

How many of you love avocadoes?

My wife and I do! With our family cancer history of hormone cancers, we will still enjoy but limit our avocado or guacamole to less than once a week.

Previous laboratory cancer cell studies have shown purified nutrients and plant chemicals in avocadoes suggests this fruit has anticancer activities. But actual human intake and cancer risk have not been evaluated until recently.

In April 2023 a research study of data from 45,289 men in the Health Professionals Follow-Up Study (HPFS) and 67,039 women in the Nurses’ Health Study (NHS) evaluated avocado consumption and the risk of cancer.

In the HPFS, consuming more than 1 avocado a week was associated with a decreased risk of only colorectal cancer, lung cancer, and bladder cancer in men. Other cancer rates were not affected. In the NHS, avocado consumption was associated with increased risk of breast cancer in older postmenopausal women. Neither group noticed a decreased or increased overall cancer...

Tomatoes and Cancer Prevention

Tomatoes are a delicious and nutritious fruit that has been linked to a number of health benefits, including a reduced risk of cancer. The key compound in tomatoes that appears to be responsible for their cancer-fighting properties is lycopene. Lycopene is a carotenoid, which is a type of antioxidant that can protect cells from damage.

A number of studies have shown that people who eat more tomatoes or tomato products have a lower risk of developing certain types of cancer. For example, a study published in the journal Cancer Epidemiology, Biomarkers & Prevention found that men who ate the most tomatoes had a 33% lower risk of developing prostate cancer than men who ate the least tomatoes. Another study, published in the journal Cancer Causes & Control, found that women who ate the most tomato sauce had a 20% lower risk of developing ovarian cancer than women who ate the least tomato sauce.

In addition to prostate and ovarian cancer, tomatoes...

Maca root (Lepidium meyenii) extract is a worldwide consumed food supplement for sexual dysfunctions, increasing sperm production and its motility, and alleviating menopausal symptoms. Various bioactivities of maca include enhanced reproductive health, antifatigue, antioxidation, neuroprotection, antimicrobial activity, anticancer, hepatoprotection, immunomodulation, and improving skin health and digestive system's function.

MACA has not been well studied for its impact on cancer. Over all Brassica vegetables, such as mustard, broccoli, and MACA, is associated with decreased risk of developing cancer.
There is a laboratory cancer cell study showing ingredients in MACA decrease liver cancer and colon cancer cell growth.

But another laboratory cell study shows that high dose maca encourages triple negative breast cancer cells to metastasize.

In summary, at the time of publication MACA has not been studied in humans. Based on its known impact on hormones and laboratory cell...

Prebiotics provide nutrients that help your good bacteria (flora/microbiome) to grow in your gut. The good microbiome supports your immune system and helps your body fight cancer and infections.

Your gut microbiome supports hematopoietic stem cell transplantation, chemotherapy, immunomodulating therapy and cancer immunotherapy.

You get a lot of prebiotics from the following 11 foods.

1. Chicory root
2. Dandelion greens
3. Jerusalem artichoke
4. Garlic, Onions & Leeks
5. Asparagus
6. Bananas
7. Barley
8. Oats
9. Apples
10. Flaxseeds
11. Seaweed

A couple of servings a day support the good bacteria in your gut. It would take a lot of supplement prebiotic capsules to get the same effect as a serving or two of food.
