Specific references to Canned Tuna throughout Geoff Bond's publications.
The idea of eating salad for breakfast does indeed run counter to our Western cultural programming, but it is something that many societies do, notably in Africa. A copious mixed salad with some avocado, tuna flakes, or shrimp makes a great start to the day. Again, make it a large portion— at least one pound per person. It is not really so much: One large tomato, one cucumber, some onion, and some lettuce leaves make 9 oz of plant food. Round it off with 3 oz of canned tuna, and you have a hearty breakfast. ~Paleo in a Nutshell p.87
A suitable choice for lunch is a mixed salad, and an appropriate quantity might be 12 oz. Weigh foods until you are used to estimating the quantities by eye— it's larger than you are used to. Get in the habit of thinking that a salad is often in two parts: The salad vegetables, comprised uniquely of foods from Food Group 3 (Non-starchy Vegetables), and some additions of protein-rich foods from Food Group 6 (Meat, Poultry, Eggs, and Fish). You can add tuna or chicken breast, for example, to the salad or eat as a side dish. Use a simple homemade vinaigrette of mustard, olive oil, lemon juice, and vinegar. ~Paleo in a Nutshell p.88
For children/adolescents, Have stocks of oily fish like canned salmon, sardines, and tuna. ~Paleo in a Nutshell p.107
It was not until the 1960s that fish farming or "aquaculture" came of age. Since then, salmon, trout, catfish, and tilapia have been farmed on an industrial scale. They have almost completely displaced their wild counterparts from our tables. Less commonly farmed are carp, mullet, redfish, and sea bass. Efforts are already under way to farm tuna, cod, sea bream, and turbot in vast enclosed offshore pens. ~Deadly Harvest p.62
Up until the 1970s, virtually the only fish on our plates were ones caught in the wild. Now, we have seen the huge volume of fish, notably salmon and trout, that are produced by fish farms. Even so, most other species that we find in our supermarkets (fresh, frozen, or canned) are still wild. Cod, halibut, tuna, sardine, plaice, mackerel, pollock, herring, and many others, for the time being at least, are all caught in the wild. We can say that many of them conform to the Savanna Model while the others, if not conforming, are certainly not harmful. ~Deadly Harvest p.63
Omega-3 EFAs are found in plants and animal matter. In plants, the most common form is alpha-linolenic acid (ALA), found particularly in walnuts, flaxseed, hempseed, and rapeseed (canola oil). In animals, omega-3 oils are particularly found in "oily" fish, such as sardines, salmon, trout, and tuna. ~Deadly Harvest p.104
Remembering that starch is not a great thing to be putting in the body, let us keep things in perspective. There are occasions when there are small amounts of starch in a protein dish, like a few bits of sweet corn in a tuna salad. This is unimportant provided that the protein dominates. The trouble arises when the proteins and starches are equally balanced and they fight each other for priority. This is the case with so much of what we eat today— for example, steak and french fries, hot dogs, hamburgers, and tuna sandwiches. Starch/protein combinations cause trouble when they are present in nearly equal proportions and they fight each other for dominance. ~Deadly Harvest p.121
