From fast food restaurants and delis exploding with high-calorie sandwiches to salad bars stocked with high fat and high sugar salad add-ons — lunchtime can be a minefield of temptation for those trying to eat a healthy and balanced diet.

But a healthful and enjoyable lunch can be done. These simple tips can help.

Your meal should include lean protein, whole-grain carbohydrates, and produce. Roughly half of your plate should be vegetables or fruit; one-quarter should be lean protein such as fish, chicken, turkey, tofu, beans, or low-fat cottage cheese; and one-quarter should be whole grains, such as one slice of whole-grain bread, or half a cup of brown rice, whole-wheat pasta, or quinoa. You might include a small amount of healthy fat, such as a tablespoon of oil-and-vinegar dressing on your salad.

Salad can be a good way to go, but you need to be careful. Regular salad dressings, cheeses, and mayonnaise-based salads (such as tuna, chicken, and egg salads) can contain unhealthy fats, hidden sugar, and salt. Not to mention lots of calories. Here’s the trick to a healthy and satisfying lunch salad.

Step 1: Build a vegetable base. Load your plate with leafy greens and raw or grilled vegetables.

Step 2: Add some protein — a few scoops of garbanzo or kidney beans. Beans are an excellent source of fiber — and they’re filling! Other good selections include grilled chicken, low-fat cottage cheese, or chopped eggs. Go light on the cheese. A sprinkle of a strongly flavored cheese like feta or Parmesan can deliver flavor with fewer calories.

Step 3: Add a small amount of healthy fat. Sprinkle on the nuts and seeds. They are high in heart-healthy unsaturated fat and healthy protein, give you a feeling of fullness, and help food stay in your stomach longer. You might also opt for a dash of oil and vinegar.

Step 4: Whole grains and fruit make a nice addition to a creative salad. Look for whole grains like barley or bulgur wheat to sprinkle on top. Or add a few slices of fruit.

The foods we eat can affect our risk of developing certain types of cancer. High energy and high fat diets can lead to obesity and are generally thought to increase the risk of some cancers. Plant-based diets high in fresh fruits, vegetables, legumes and wholegrain foods may help to prevent cancer.

Diet is just one of the lifestyle factors that influence the risk of developing cancer. Smoking, obesity, alcohol, sun exposure and physical activity levels are also important. Although some foods can affect cancer risk, there is no evidence that specific foods can cause or cure cancer.

Food and some common cancers
Some common cancers (and how they are affected by what we eat) include:

• Lung cancer – this is the leading cause of death from cancer in the world and smoking is mostly responsible. There is convincing evidence that diets high in vegetables and fruits are protective against lung cancer. It is thought that compounds called carotenoids (present in significant amounts in fruits and vegetables), as well as vitamin E, are probably responsible for some of this effect. However, the use of antioxidant supplements, such as beta-carotene and vitamin E, has not been proven to be effective in either prevention or treatment of lung cancer and may, in fact, increase the risk of developing cancer in those who smoke. While fruits and vegetables may offer some degree of protection, not smoking in the first place is by far the best prevention.

• Breast cancer – this is the most common type of cancer in women in the world. There is an increased risk of breast cancer with factors such as rapid early growth, greater adult height and weight gain in adulthood. Much of the risk of developing breast cancer involves factors that influence oestrogen levels during a woman’s reproductive life, such as age of menarche (first period), number of pregnancies and breastfeeding practices. Post menopausal women who are carrying too much weight, especially around their middle, have more than twice the average risk of breast cancer. Diets high in mono-unsaturated fat and high in vegetables and fruits may reduce the risk, while alcohol consumption increases the risk.

• Prostate cancer – a quarter of all new cancers diagnosed in men in UK is prostate cancer. Vegetables, soy in particular may decrease the risk, while a high fat diet that comprises mostly animal fat sources (such as dairy products, fatty meats and takeaway foods) may increase the risk. Lycopene is a potent antioxidant found in tomatoes, tomato-based products, watermelon and strawberries. It may also help lower the risk of prostate cancer.

• Bowel cancer – this is the fourth most common cancer in the world. Up to 70 per cent of cases can be prevented by following a healthy lifestyle. Keeping a healthy weight, being physically active and a diet high in vegetables and fibre are protective, while consuming a large amount of red meat (especially processed meat) and alcohol may increase the risk.

Foods to ‘eat less’
Foods to limit in your diet or eat less of include:

• Fatty processed red meats

• Highly processed foods that are low in fibre

• Heavily salted and pickled foods.

Foods to ‘eat more’
The strongest protective anti-cancer effect has been shown with:

• Vegetables, especially raw vegetables or salads

• Leafy green vegetables

• Carrots

• Tomatoes

• Citrus fruits

• Cruciferous vegetables like broccoli, cabbage, brussels sprouts, bok choy and other Asian greens.

Include more of these vegetables and fruits in your diet along with other varieties.

Seven a day
Eating seven or more serves daily of a variety of grains, grain products, legumes, roots and tubers will also provide protective benefits against cancer. The less processed the grains, the better. Diets high in refined starch and refined sugar may increase the risk of stomach cancer and bowel cancer.

Meat and bowel cancer
There is now convincing scientific evidence that eating processed meat increases bowel cancer risk. The World Cancer Research Fund (WCRF) has recently recommended that people avoid eating processed meat. Processed meats are any meat that has been preserved by curing, salting or smoking, or by adding chemical preservatives. These meats include hot dogs, ham, bacon and some sausages and burgers.

It is recommended that children are not given processed meats at all. This is because many of the habits we develop as children last into adulthood. Substitutes for processed meats that are recommended for children include poultry or fish, low fat cheese or small amounts of lean meat.

The WCRF also recommends limiting the amount of fresh red meat we eat to 500g (cooked weight) a week. This is because there is convincing evidence that red meat also increases a person’s risk of bowel cancer.

Some research suggests that eating burnt or charred meat may increase cancer risk, but the evidence is unclear.

Fats and cancer
There has been a great deal of interest in the possible association between fat and cancer. Current evidence does not indicate a direct link between fat intake and particular types of cancer (with the possible exception of prostate cancer). However, a high fat diet may lead to obesity, which is a risk factor for several cancers including cancer of the colon, breast, kidney, oesophagus, gallbladder and endometrium.

Supplements are not the answer
Results of studies that show a protective effect of foods containing certain nutrients should not be taken to mean that these nutrients, when isolated and taken as supplements, will provide the same benefits for cancer prevention. In some cases, there has been an increased risk of cancer in those people who take nutrient supplements at doses higher than the amount of that nutrient normally eaten in foods.

Suspect foods examined
While a high energy, low fibre diet may increase a person’s risk of developing cancer, some individual foods have also been singled out as potentially causing cancer (carcinogenic). These include:

• Artificial sweeteners – such as aspartame, saccharin and cyclamate. Laboratory rats can develop bladder cancer if fed huge amounts of saccharin or cyclamate, although this is at levels thousands of times greater than a normal diet. International studies agree that humans aren’t affected in the same way. Artificial sweeteners are considered safe to eat.

• Cured, pickled or salty foods – there is no conclusive evidence that red meat causes cancer. However, bacon and other cured or pickled meats contain a substance called nitrate, which has the potential to cause cancer in laboratory animals when eaten in huge doses. How this research relates to humans isn’t clear. To be on the safe side, it is best to limit the amount of cured meats in the diet because they are generally high in fat and salt. Salt has also been associated with an increased risk of stomach cancer and should be consumed in limited amounts.

• Burnt or barbecued foods – a group of carcinogenic substances called polycyclic aromatic hydrocarbons (PAHs) can be produced if foods are overheated or burnt. Although charred or smoked foods could contain traces of PAHs, experts agree that the amount in the average UK diet is too low to be considered a significant cancer risk. However, when cooking, it’s best to use relatively low temperature methods wherever possible. These include steaming, boiling, poaching, stewing, casseroling, braising, baking, stir-frying, microwaving or roasting. Avoiding char-grilled meats and foods would also be smart.

• Peanuts – some laboratory animals can develop cancer after eating peanuts that are contaminated with toxin-producing moulds. However, peanuts sold in the UK are generally uncontaminated and contamination is routinely screened for.

• Alcohol – consuming alcohol increases the risk of cancers of the mouth, pharynx, larynx, oesophagus, breast and liver. The risk is even greater in those people who smoke. Alcohol has also been associated with colon, breast and rectal cancers. Men should drink less than two standard drinks a day and women less than one standard drink a day.

Treating cancer with food
While food plays an important role in preventing some cancers, the therapeutic value of food in treating existing cancer is less clear. It is true that a person with cancer needs excellent nutrition in order to better cope with the physical demands of the illness and the rigours of medical treatment. However, claims that particular foods, vitamins or micro nutrients can kill cancer cells should be viewed with scepticism To date, there is little scientific proof that a particular food or supplement can cure cancer or destroy cancer cells.

Recently some Japanese studies have found that green tea may delay the development and spread of certain cancers. Other studies have suggested that soy may also have a similar effect. Although this work is preliminary, it may suggest a more important role for food in the treatment of cancer in the future.

Nutrition for the person with cancer is important for many reasons, including:

• The immune system needs bolstering to fight at full strength.

• The diet may be adjusted to cope with various symptoms, such as constipation, diarrhoea or nausea.

• Loss of appetite or an increased metabolism means that high energy foods may need to be included in the daily diet.

• Extra protein may be needed to help prevent loss of muscle from weight loss.

Things to remember

• High fat, low fibre diets may increase the risk of many cancers, including bowel, lung, prostate and uterine cancers.

• You can reduce your risk of developing cancer by eating more fresh fruits, leafy green vegetables and wholegrain foods.

• Even though diet can influence your risk of developing cancer, there is little evidence that special foods can be used to cure existing cancers.
